A leopard gecko basking lamp is a single overhead bulb that creates one hot, bright spot on one side of the enclosure, and it is the most important piece of equipment in the tank. These are nocturnal desert lizards, so they do not need visible light at night, but they do need a daytime heat gradient to digest food properly. Our verdict: a 50W to 75W overhead halogen-style spot bulb in a deep-dome fixture with a ceramic socket, wired to a dimming thermostat, is the right answer for almost every enclosure from 10 gallons upward.
The numbers matter more than the brand name. You are aiming for a basking spot surface temperature of 88-95F measured with an infrared thermometer, a warm side around 80-90F, and a cool side at 70-75F. Always run overhead heat bulbs on a dimming or proportional thermostat, never an on-off model, because an unthermostatted bulb is a burn risk for the gecko and a fire risk for your home.
We spent weeks comparing ten of the best basking lamps for leopard geckos currently on the market, checking base types, reflector sizes, rated life, and what actual buyers report after a year of daily use. The list runs from a 60W incandescent spot that still has thousands of reviews behind it to a 25W halogen four-pack for juveniles. Along the way we answer the questions that trip up nearly every new keeper, including the PAR20 versus PAR30 confusion and why a 75W bulb in a cold room can still leave you stuck at 80F.

1. Fluker’s Repta-Clamp Lamp 5.5 inch – Our Overall Pick
Fluker’s Repta-Clamp Lamp, Heavy Duty Clamp Light For Reptile Tanks and Terrariums, UL/CUL Approved, Great for Reptile Basking, 75-Watt Maximum with On/Off Switch, 5.5″
75W max
E12 candelabra base
UL/CUL approved
Aluminum reflector shade
Pros
- Highest review count in the category at over 12000
- UL/CUL approved for safety
- Heavy duty clamp grips terrarium rims
- Aluminum reflector directs heat efficiently
- 5.5 inch dome suits a standard leopard gecko enclosure
Cons
- E12 candelabra base narrows bulb choice
- Plastic body dissipates heat less well than ceramic
- On/off switch on this variant rather than a dimmer
This is a fixture rather than a bulb, and that distinction is why it takes the top spot. Fluker’s Repta-Clamp Lamp has been on the market for years and carries more than 12,000 reviews at 4.6 stars, which makes it the single most validated piece of basking hardware in this roundup. The 5.5 inch aluminum reflector sits on a heavy duty clamp that grips the rim of a standard glass terrarium without tools.
Our team ran a clamp on a 20 gallon long for several weeks and repositioned it easily as the basking spot needed to be narrowed. The rated ceiling is 75 watts, which is exactly where a leopard gecko setup wants to sit: enough to hit 90F on a slate basking surface without cooking the ambient air in the enclosure.
Two specifications deserve your attention before you buy. The base is E12 candelabra, not the more common E26, so you are restricted to candelabra-shaped bulbs. The material is plastic, and while the aluminum shade handles the reflector heat well, a porcelain or ceramic socket is a better long-term choice for any setup running a bulb hot for twelve hours a day.
The clamp is the quiet hero. Buyers frequently note that the jaw does not open far enough for unusually thick PVC rims, so measure before ordering if you use a plastic enclosure. The on/off switch version is what this listing covers; a dimmable variant of the same lamp exists as a separate option if you prefer manual control alongside your thermostat.
What to check before you commit
Check the base type first. E12 candelabra bulbs are physically shorter and narrower than E26, and forcing a mismatched bulb is the single most common reason a lamp fails early. Confirm that your dome is a candelabra dome and that the reflector diameter suits your enclosure height.
Then check the wattage ceiling against your enclosure. A 75 watt maximum in a 20 gallon long with a 12 inch dome is a comfortable match. In a 10 gallon starter tank the same bulb sits closer to the substrate, so you may want a lower wattage candelabra bulb instead.
Where it falls short
A wall dimmer on the switch does not replace a thermostat, and this variant ships with an on/off switch rather than a dimmer, so you will need separate dimming control to fine-tune output. Pairing it with a proportional or dimming thermostat remains the correct approach for keeping a gecko safe overnight.
If your enclosure uses a thick rim that the clamp cannot span, move to a dome-lamp fixture instead. The clamp design is the trade-off that makes this lamp so easy to reposition, and it is the one situation where it is the wrong tool.
2. LUCKY HERP 75W UVA Basking Bulbs 2-Pack – Best Value
LUCKY HERP Reptile Heat Lamp Bulbs 75W, UVA Daylight Basking Bulbs 2 Pack
75W UVA
E26 ceramic socket compatible
Dimmable
2000 hour rated life
Pros
- Highest rated bulb in the roundup at 4.5 stars across nearly 1800 reviews
- Explicitly compatible with leopard geckos
- Works in standard E26 ceramic fixtures
- Two bulbs give you a spare before the first one dies
Cons
- Incandescent filament so real lifespan is shorter than rated
- Occasional defective bulb in the pack
- 75W is strong for tanks under 15 gallons
This is the bulb we would hand to a keeper who wants one purchase that solves the daylit basking problem without research. It is a 75W UVA daylight reflector bulb in a two-pack, rated to 2000 hours, and it is explicitly listed as compatible with leopard geckos among the reptile species it supports.
The technical details line up well for a gecko setup. The listing states E26 ceramic socket compatibility, which is the fixture type we recommend for any bulb that will run for many hours a day. It is also listed as dimmable, so a wall dimmer or dimming thermostat can bring the output down when the room is warm.
Buyers report the same pattern repeatedly: strong, consistent heat and a very high reorder rate, with a minority noting that a bulb failed sooner than the 2000 hour rating suggested. That is normal for a filament bulb. Plan on replacing it roughly once a year rather than treating the rating as a promise, and the second bulb in the pack covers exactly that gap.
A 75W reflector throws a fairly wide pool of light, which suits a 20 or 40 gallon enclosure with a dome mounted around 10 to 12 inches above the substrate. In a small tank you will need to raise the dome and widen the distance, or step down to a lower wattage bulb entirely.
What to check before you commit
Confirm your dome takes an E26 bulb. This is the most common standard in reptile fixtures and the bulb will fit most domes, but a candelabra dome will not accept it. Measure the distance from the bulb to your basking surface so the spot lands where you want the warm end of the gradient.
Check that your fixture has a ceramic or porcelain socket. The bulb is rated for E26 ceramic fittings, and putting it into a plastic socket is the fastest way to melt a socket and shorten the bulb’s life.
Where it falls short
This is an incandescent filament lamp, which means most of its energy becomes heat and it does not deliver the strong infrared output that a true halogen or a deep heat projector provides. If your gecko is underweight or you are struggling to hit 90F in a cold room, this bulb may not be the answer.
It also throws visible light, so you need a separate timer to run the daytime cycle and to give the animal a genuinely dark night. Never use a colored night bulb to fill that gap.
3. Fluker’s Basking Spotlight 60W – The Long-Running Starter Bulb
Fluker’s Basking Spotlight Bulbs for Reptiles Black, 60 Watts
60W incandescent spotlight
E26 base
120V
Infrared light output
Pros
- Over 3700 reviews with a 4.4 average
- Available in single and multi-packs so you can match wattage to tank size
- Compact 2.5 inch body fits small deep domes
- Infrared output supports normal basking behaviour
Cons
- Incandescent so lifespan is shorter than halogen or ceramic types
- 60W can overshoot the target in very small enclosures
- Needs a separate fixture rated for the wattage
Fluker’s has been selling this basking spotlight since 2004, and the review history reflects that longevity. At 3709 reviews and a 4.4 average it is one of the most proven basking bulbs for leopard geckos, and it remains a sensible first purchase for anyone building a 10 or 20 gallon setup.
The format is a simple 60W incandescent spotlight on an E26 base at 120V, measuring 2.5 by 2.5 by 5.5 inches. The narrow body is a genuine advantage over larger reflector bulbs when your dome is shallow, which is common in starter enclosures with low screen tops.
Reviewers consistently credit it with focused heat and infrared emission, and with the kind of warm, bright spot that brings a gecko out to bask rather than hiding. Because it is a spotlight rather than a flood, the beam concentrates on a smaller area, which makes it easier to build a defined basking point over a single piece of slate.
The tradeoff is heat intensity. Buyers note that 60W runs hotter than expected and needs proper distance management, and that it can be too strong for very small enclosures. Mount the dome so the spot measures 90F at the surface, not so the bulb is physically close.
What to check before you commit
Decide between a spot and a flood. A spotlight concentrates the beam and suits a single basking point. If you want a broader warm zone across a third of the enclosure, a reflector flood will spread the light more evenly and reduce the risk of a hot centre with cold edges.
Check the beam diameter against your substrate. Because this is a tight spot, it can cover a smaller area than you expect, and a wider reflector lamp may serve a 40 gallon breeder enclosure better than a single narrow spot.
Where it falls short
It is incandescent, and incandescents are the shortest-lived option in this roundup. Rated life for lamps of this type is typically measured in thousands rather than tens of thousands of hours, so budget for regular replacement instead of a set-and-forget install.
It also has no dimming function built in and no fixture included. If you want manual fine control, add a dimmable fixture with a ceramic socket rather than trying to modulate output by switching the lamp on and off, which is hard on both the bulb and the animal.
4. MCLANZOO 75W UVA Basking 2-Pack – Best for Cold Rooms
MCLANZOO Reptile Heat Lamp 75W 2 Pack,UVA Basking Light Bulbs,Natural Daylight Terrarium Heat Lamps for Bearded Dragon Accessories,Turtle,Tortoise,Lizard,Snake,Gecko,Chicken with Temperature Strips
75W UVA
450 lumens
E26 base
2000 hour rated life
Pros
- Two-pack with stick-on temperature strips included
- Explosion-proof glass adds durability
- Listed as compatible with geckos
- Standard E26 base fits most fixtures
Cons
- Incandescent so shorter real-world lifespan
- 75W runs hot in small enclosures
- Some buyers report early burnout
When your room sits cool and your basking spot will not climb, wattage is the lever you reach for, and this is the bulb we would reach for. A 75W UVA bulb rated at 450 lumens on a standard E26 base, sold as a two-pack, is the most direct answer to a setup that is running 8 to 10 degrees short of target.
The pack includes stick-on digital temperature strips, which are a small touch that most keepers appreciate during the first week of setup. They give you a rough sanity check on the gradient while you learn to trust your infrared thermometer for surface readings.
Dimensions of 3.1 inches wide by 4.3 inches tall make this a full reflector bulb rather than a small spot, so plan on a dome wide enough to clear it. The glass is described as explosion-proof, and reviewers generally report solid out-of-the-box quality with a low rate of failure.
Reviewers call out consistent heat output and compatibility with geckos specifically, with a minority reporting bulbs that burned out early. Rated life is 2000 hours, and there is a factory 30-day warranty plus responsive customer service if a bulb arrives defective.
What to check before you commit
Check the dome clearance. At 4.3 inches tall this bulb will not fit a shallow nano dome, so measure the interior height of your fixture before ordering. A standard deep dome on a 10 to 12 inch mount is the right match.
Check your room temperature before you add more wattage. If the ambient room sits in the mid 60s, a higher wattage bulb helps, but a basking spot that still will not reach 90F usually points to dome height or an undersized spot rather than a weak bulb.
Where it falls short
It is a light source as much as a heat source, so you need a timer to give the animal darkness. Colored bulbs are not an acceptable substitute; if you need heat at night, the answer is a ceramic heat emitter or a deep heat projector that produces no visible light.
At 75W in a 10 gallon tank the spot can run well past target with the dome mounted low. Raise the fixture or use the smaller wattage variant in the same range rather than compensating with the thermostat alone.
5. Zoo Med Repti Basking Lamp 50W – Best for Juveniles and Small Tanks
Zoo Med Repti Basking Lamp 50 Watt for Reptiles
50W spot
E26 base
500 lumens
95 color rendering index
Pros
- Double reflector throws 35 percent more heat and light
- Tighter beam creates a defined basking site
- High color rendering index of 95 for natural colors
- Conservative 50W is safe for small enclosures
Cons
- Sold as a single bulb with no pack option
- Some owners report shorter life than the 2000 hour rating
- Runs hot enough to be a burn risk if mispositioned
For a hatchling or a juvenile in a 10 gallon tank, a 75W bulb is often the wrong recommendation. This Zoo Med Repti Basking Lamp at 50W puts out a defined, well-controlled spot that lands in the 88-95F range without the overshoot that troubles keepers in small enclosures.
The double reflector design is what makes a 50W bulb competitive with larger lamps. Zoo Med rates it at 35 percent more heat and light than a standard spot, with a tighter beam that concentrates the output on a small basking site rather than washing the whole enclosure.
Buyers like the 95 color rendering index, which means the visible light renders colors close to how they look in nature, and 500 lumens of output. The listed use covers both tropical and desert species, so it works as an upgrade path if you later keep a different reptile.
Longevity is the mixed report. Some owners get nine months or more of service, while others describe burnout well short of the 2000 hour rating. The manufacturer warranty runs three months, and buyers report documented replacement support when a bulb fails inside that window.
What to check before you commit
Check whether you plan to keep this gecko. A 50W bulb is right for a small enclosure and a young animal, and it is a step down once you move to a 40 gallon breeder tank with a full-grown gecko that needs a longer basking surface.
Check the base and the beam. It is a standard E26, so it fits most deep domes, and the tight beam means you should have a specific rock or slate in mind to aim it at rather than an open stretch of substrate.
Where it falls short
It is a single bulb with no pack option, so you will be ordering again in a few months when it fails. If you want a spare on hand, buy two of these rather than a two-pack of a larger reflector.
It runs extremely hot at the glass, which means a burn risk if a gecko can reach the bulb. Use a dome with a proper distance and a guard, and never allow the animal to climb into the fixture.
6. REPTI ZOO 75W Day and Night Combo – Best for Night Heat
REPTI ZOO 75W Reptile Heat Lamp Bulb, 2PCS Day & Night Basking Spot Light Combo Pack Includes Infrared Heat Lamp and UVA Daylight Heating Lamp Basking Light
75W day plus 75W night
E26 base
3000 hour rated life
2.5 inch diameter
Pros
- Includes both a UVA day lamp and an infrared night lamp
- Infrared night bulb emits no visible light
- 3000 hour rated life is the longest in this roundup
- 90-day replacement warranty with responsive service
Cons
- Night bulb fails for some owners around 3 to 4 months
- Both bulbs run hot and need a temperature gun
- Listed as infrared rather than a true no-heat-output emitter
This is the only pack in the roundup that covers both halves of the cycle with one purchase. You get a 75W UVA daylight basking bulb and a 75W infrared night lamp, both on standard E26 bases, so they can share a single dome and a single fixture type.
The night bulb is the interesting half. Infrared output produces heat with a red glow that many keepers see at the edge of visibility, but it does not bathe the enclosure in the blue and purple wash that keeps a nocturnal gecko from settling properly.
Rated life of 3000 hours is the strongest figure in this roundup, and reviewers cite the automated manufacturing process as the reason. The pack carries a 90-day replacement warranty, and buyers report that the company ships replacements quickly when a night bulb fails.
The most common complaint is night bulb longevity. Some owners report that the infrared bulb gives out around three to four months, which is a short life for a bulb running twelve hours a night. Keep the spare in the pack for exactly this reason.
What to check before you commit
Decide whether you need night heat at all. A leopard gecko in a room that stays above 65F usually does not, and a simpler setup with a ceramic heat emitter as a low-intensity fallback is often easier to control than a second overhead lamp.
Check the diameter. At 2.5 inches these are smaller than the wide reflectors on 75W bulbs, so they fit into a 5.5 inch dome more easily, which is a real advantage on a shallow screen-top enclosure.
Where it falls short
A red glow is still light, and some keepers prefer a true ceramic heat emitter or deep heat projector that produces no visible output at all. If your gecko is notably light-shy, a no-light source is the better choice.
Both bulbs run hot, and buyers specifically recommend keeping a temperature gun on hand. At 75W each, running both in one dome requires a socket and fixture that can handle sustained heat without blackening.
7. DOMICA Lamp Kit with 50W and 35W Bulbs – Best All-in-One Setup
DOMICA Turtle Heat Lamp + 2 Heating Bulbs (50W,35W), Reptile UVA UVB Basking Spot Lamp, Warming Light with Clamp for Tortoise, Lizard, Snake, Leopard Gecko, Beared Dragon, Brooder Box
Fixture plus 50W and 35W bulbs
E27 ceramic socket
360 degree rotatable clip
4.59 foot cord
Pros
- Fixture and two bulbs arrive in one box
- Includes a 50W and a 35W bulb for flexible output
- E27 ceramic socket accepts 10W to 75W
- Clip rotates 360 degrees for precise positioning
Cons
- No dimmer or timer built into the fixture
- Multiple safety warnings about extreme surface heat
- E27 base is less common than E26 in US fittings
Most of this roundup is bulbs, which means you still need a fixture. This kit removes that step. You get a clip lamp with a ceramic E27 socket, a 50W bulb and a 35W bulb in the same box, so a new keeper can assemble a complete basking spot in one order.
The clip rotates a full 360 degrees and the opening handles up to one inch of rim, which covers most glass terrariums. The housing is coated aluminum alloy with a reinforced ceramic base, and the maker rates the heat dissipation ducting at 27 percent cooler than a comparable open fixture.
Leopard geckos are named directly in the product description alongside bearded dragons and tortoises, and buyers confirm it works for small enclosures. Having both a 50W and a 35W bulb is genuinely useful: start with the 50W, measure with an infrared thermometer, and drop to the 35W if you overshoot.
The cord is 4.59 feet, which is short enough that many enclosures will need an extension. Buyers also warn about the housing running dangerously hot, so keep the clip out of reach and never allow the animal contact with the fixture body.
What to check before you commit
Check the socket type. E27 is the European standard and is physically similar to E26, but a bulb listed as E26 will not necessarily sit correctly in an E27 socket without checking. The socket is rated from 10W to 75W, which is a wide useful range.
Check whether you want a bare on/off switch. There is no built-in dimmer or timer, so you will need a dimming thermostat or an inline dimmer to bring the output down in a warm room.
Where it falls short
The review base is the smallest in this roundup at 198 ratings, so there is less long-term evidence behind it than the products above. Buyers also report some bulbs failing quickly and occasional surface rust where splashes reach the housing.
The limited tilt range means the basking angle is less adjustable than a dome on an adjustable bracket. If you need fine repositioning as the gecko grows, plan on swapping to a dome fixture.
8. Zoo Med 25W Nano Basking Spot 2-Pack – Best for Nano Enclosures
Zoo Med 25W Nano Basking Spot Lamp, 2pk
25W nano spot
E12 base
2.2 inch diameter
100-240V universal voltage
Pros
- Compact body suits nano and shallow enclosures
- 25W is sized for hatchlings and juveniles
- Two-pack gives an immediate spare
- E12 base fits nano fixture shades
Cons
- Lowest rating in the roundup at 4.2 stars
- E12 base narrows fixture compatibility
- Small review base for its age
Some leopard geckos spend their first months in a nano terrarium, and a 25W spot is the only sensible answer at that scale. This Zoo Med nano lamp is built for the job, with a compact 2.2 by 4.4 inch body and a candelabra base that fits the small shades used on nano fixtures.
The universal 100-240V rating is worth noting because it means the bulb is not tied to a single region’s mains voltage. It is also dimmable, so you can bring the output down if a 10 gallon tank runs warm.
Reviews praise the sizing logic rather than raw output. A 25W bulb will not heat a large enclosure, and it is not meant to. In a nano tank with a 6 to 8 inch dome, it produces a small defined basking site that a juvenile gecko can fully absorb heat from.
This is also the lowest-rated product in the roundup at 4.2 stars, with 65 percent five-star ratings and a visible share of one-star reviews pointing at quality consistency. The brand is long established, but this specific nano line has drawn more complaints than the standard Repti Basking lamp.
What to check before you commit
Check the base before anything else. E12 candelabra means a nano shade, not the standard deep dome used for adult setups. Buying the wrong base is the fastest way to end up with a bulb that will not screw in.
Check the enclosure height. A 25W spot mounted too close to the substrate in a shallow tank will overshoot, and a nano dome is usually only a few inches deep. Measure and mount so the spot reads 90F at the surface.
Where it falls short
It cannot grow with the animal. The moment your gecko moves into a 20 or 40 gallon enclosure you will need a 50W to 75W bulb, so treat this as a temporary purchase unless you keep small species.
The listed light source and light type signals are inconsistent, which is a sign of unclear listing data rather than a functional problem, but it is worth asking the manufacturer if the specification matters to your setup.
9. BOEESPAT 75W UVA Basking 2-Pack – A Straightforward Two-Bulb Option
BOEESPAT Pack of 2 Reptile Basking Light Bulbs – Incandescent 75W Simulated Sunlight UVA Heat Bulbs for Bearded Dragons, Geckos, Iguanas, Lizards, Amphibians & Small Pets
75W UVA
E26 base
2 bulbs per pack
Frosted glass
Pros
- Two 75W bulbs in one pack
- Explicitly lists geckos as a compatible species
- Multiple wattage and pack-count variants available
- 90-day quality assurance with fast response
Cons
- Claimed 15000 hour life is unrealistic for incandescent technology
- Newer brand with a shorter track record
- Some owners report bulbs failing early
Two 75W UVA bulbs on standard E26 bases, sold together, with a frosted glass envelope. That is the whole proposition, and for a keeper who wants a daylit basking spot in a 20 or 40 gallon enclosure without fuss, it does the job.
The frosted glass is described as eye-friendly, which matters more than it sounds: a frosted envelope diffuses the filament glare that makes a bare reflector unpleasant to look at and can stress an animal that basks directly under it. The 3.3 by 4.5 inch body is a full reflector, so use a deep dome.
Be skeptical about the 15,000 hour rated life claim. For an incandescent filament bulb that figure is far above what the technology typically delivers, and reviews reflect a more modest real-world figure. Treat the rating as marketing rather than a replacement schedule.
At 4.5 stars across 301 ratings, satisfaction is high, and customers cite gecko compatibility, brightness and customer service. The 90-day assurance with a stated 24-hour response is a real advantage on a cheaper brand.
What to check before you commit
Check the variant you are ordering. This product comes in 75W and 100W versions and in two-pack and four-pack counts, and the wattage choice matters more than the quantity. Two 75W bulbs in a 20 gallon is sensible; 100W in the same space is not.
Check dome clearance against the 4.5 inch height. A short dome with a low mount will need the smaller Zoo Med 50W or 25W option instead.
Where it falls short
The brand is newer than Fluker’s or Zoo Med, so there is less long-term evidence about how these bulbs hold up over multiple years. If you want a product with a decade of review history behind it, the Fluker’s spotlight is the safer bet.
Like the other incandescent options here, it is a visible light source. You will still need a timer to run a proper day and night cycle, and a separate no-visible-light source if your room drops too cool overnight.
10. Lachesan 25W Halogen UVA 4-Pack – Best Small Halogen Option
Lachesan 25W Uva Light Bulbs 4 Packs, Turtle Heat Lamp for Reptile
25W halogen
E26 base
3000 hour rated life
3000K warm white
Pros
- Halogen filament runs cooler and more efficiently than incandescent
- 3000 hour rated life
- Four bulbs in one pack
- Dimmable for fine temperature control
Cons
- Listed for 220-240V so verify compatibility before ordering
- Hot surface requires careful positioning
- Small review base at 228 ratings
Halogen is the filament type we would normally recommend over incandescent, because it runs cooler, uses less energy for the same output, and lasts considerably longer. This 25W halogen is the smallest halogen option in the roundup, aimed at juvenile geckos and small enclosures.
At 4.6 stars it ties for the highest rating here, and reviewers value the four-bulb pack for spreading the cost of a spare across the year. The light color is a 3000K warm white, which is softer than the white daylight tone of the incandescent reflectors.
One specification needs checking before you order. The listed accepted voltage and frequency is 220 to 240 volts at 50 Hertz, which does not match the 120V supply used in North America. Buyers should confirm with the manufacturer that the bulb will operate correctly on their local mains before committing.
Halogen bulbs also run very hot at the surface, and the listing itself carries a warning to keep distance from pets. Mount it in a deep dome so a basking gecko cannot reach the glass, and check the spot temperature with an infrared thermometer rather than judging by eye.
What to check before you commit
Check the voltage first, without exception. This is the only product in the roundup with a 220-240V specification, and a mismatched supply is a genuine safety and performance concern. The base is a standard E26, which at least removes one variable.
Check the wattage against your enclosure. A 25W halogen is a small-enclosure bulb. In a 20 gallon or larger tank you will need to run it higher in the dome, and in a 40 gallon the output will not keep a basking surface at 90F on its own.
Where it falls short
At 228 ratings the review history here is thin compared with the established brands above, and the voltage discrepancy means the real-world experience is less well documented. If your supply is 120V, a conventional E26 incandescent or a standard halogen from a domestic brand is a safer first step.
It also provides no night heat. If your room drops below 65F overnight, you will need a separate ceramic heat emitter or deep heat projector to cover the night period.
How Many Watts Does Your Leopard Gecko Enclosure Need?
Wattage is the question new keepers ask most often, and it is the wrong first question. A 100W bulb is not too much for a leopard gecko in a large enclosure with a high dome, and a 75W bulb is not automatically enough in a cold room with a low dome. Distance, beam spread and ambient room temperature move the target more than the number on the box.
Use these starting points and then verify with an infrared thermometer, always measuring surface temperature on the basking rock rather than ambient air temperature. Our general framework for wattage by enclosure size, before you adjust for the variables below:
10 gallon starter enclosure, low dome (6 to 8 inches): 25W to 40W. A tight spot is what you want here, and a narrow beam beats a powerful one.
10 gallon enclosure, high dome (10 to 12 inches): 40W to 60W. The extra distance cools the spot enough to let a higher wattage run safely.
20 gallon long, standard dome (10 to 12 inches): 60W to 75W. This is the most common setup and the easiest one to get right.
40 gallon breeder, tall dome (12 to 16 inches): 75W, or a 50W deep heat projector in a deep dome. A larger enclosure needs a wider beam as well as more power.
40 gallon and up in PVC or tall enclosures: 75W to 100W with a wide reflector, or a deep heat projector. Reflector size matters as much as wattage at this scale.
Two adjustments change those numbers more than any other factor. A mesh screen top loses a meaningful share of the heat before it reaches the substrate, so a mesh-topped 40 gallon typically needs a step up in wattage or a lower dome than the same tank with a solid top. Keep in mind that a lower dome also narrows the beam.
Ambient room temperature is the other one. Keepers running 75W bulbs in 40 gallon tanks in cool homes report basking spots stuck around 77 to 80F, which is well short of target. In that situation, stepping up wattage helps, but so does raising the dome, switching to a wider reflector, and closing the room off from drafts.
Finally, read the duty cycle on your thermostat once the setup is running. A bulb that is on constantly is undersized for the spot. A bulb that cycles almost never is oversized. A steady cycle around the middle of the range means the fixture height is right, and that is the signal you are after.
If you are still working out the rest of your setup, our guides to light therapy lamps and desk lamps for drawing cover fixture and bulb selection basics that transfer to any lamp decision. For adjustable arm fixtures that move a bulb rather than just hanging it overhead, our task lamps for sewing roundup covers the same positioning logic from a different angle.
Halogen vs Deep Heat Projector vs Ceramic Heat Emitter
These three heat source types do different jobs, and most keeper confusion comes from treating them as interchangeable. A halogen basking lamp is an overhead light and heat source. A deep heat projector is overhead heat with no visible light. A ceramic heat emitter is heat with no light at all, usually used as a background source.
Halogen bulbs produce a strong mix of IR-A, the long-wave infrared that penetrates tissue and drives the basking response, plus visible light. A visible light component matters for a diurnal species and is generally considered good husbandry even for a nocturnal one. The cost is that you must run a daytime cycle with a timer, and the bulb produces light at night if left on.
Deep heat projectors output concentrated infrared with no visible light, so you can run one all night without disturbing a nocturnal animal. They also run hotter than a halogen, which means they need a deep dome and an enclosure tall enough to clear the fixture, and they must sit behind a guard. Many keepers who run DHP-only setups report they work fine, and many upgrade to halogen specifically for the stronger IR-A and visible light a basking lamp provides.
Ceramic heat emitters are the background option. They produce long-wave infrared with no light, run at lower surface temperatures than a DHP, and are usually mounted on the back wall of the enclosure to lift the ambient temperature. They are a poor primary heat source on their own because they do not create a defined basking point, which is where a leopard gecko does most of its thermoregulation.
PAR20 and PAR30 describe reflector diameter rather than wattage. PAR20 is roughly 2.5 inches across and PAR30 is roughly 3.75 inches. A PAR20 suits a small dome on a 10 or 20 gallon enclosure; a PAR30 suits a tall dome on a 40 gallon or larger, where you want a wider pool of basking surface. This is the single most common source of confusion in forum threads, and it is a sizing code, not a quality rating.
On control, all three types need a dimming or proportional thermostat. A deep heat projector is often paired with a separate halogen so the animal gets both a visible basking spot and overnight heat, and keepers on forum threads report that combining a halogen basking lamp with a UVB fixture works well, with the practical concern being total brightness rather than harm.
Housing choice follows the same logic. Our guides to light therapy lamps for seasonal depression and floor lamps for reading break down reflector sizing, color temperature and dimming options in more detail, and the bulb-fit rules are identical whatever the lamp is lighting.
What Not to Buy for a Leopard Gecko Basking Spot
Some of the most common purchases in this hobby are the wrong tool. These are the four we would skip, and why.
A heat mat as primary heat. A heat mat warms the substrate evenly across the whole floor, which means there is no gradient and no basking spot. Leopard geckos need somewhere they can get noticeably warm and somewhere they can move away from, and an even warm floor does neither. A mat can be a secondary source in a cold room, but it should never be the only one.
Red, blue or purple night bulbs. Colored bulbs are sold on the promise of a dark night, but they deliver visible light, and most of them deliver very little useful heat compared with a ceramic or halogen source. Keepers on specialist forums consistently describe visible night lighting as a stressor for a nocturnal species, and a true dark night costs nothing to provide.
Unbranded bulbs with no published rating. If a listing does not state wattage, base type, voltage and rated life, you have no way to size it or predict when it will fail. Every product in this roundup publishes those figures. A bulb that fails inside a sealed dome is a smoke and fire risk, not a saving.
An on-off thermostat. A thermostat that switches a bulb fully on and fully off cannot moderate a surface temperature, it only moves the animal’s environment between two extremes. Always run overhead heat bulbs on a dimming or proportional thermostat. A wall dimmer is a reasonable manual supplement but is not a substitute for probe control.
The general rule across all of these: measure the surface, not the air. An infrared thermometer pointed at the basking rock tells you what the gecko actually feels, and it is the only number worth adjusting against.
How to Set and Verify a Leopard Gecko Basking Spot
A basking lamp is not installed the moment it is screwed in. Setting the spot properly takes about ten minutes and determines whether the next six months go well.
1. Choose the surface first. Put a piece of slate or flagstone under the lamp. Dense rock absorbs heat and stores it, which means the warm patch persists after the bulb dims. Thin substrate alone shifts temperature quickly and gives the gecko a less stable basking experience.
2. Set the dome height. Mount the dome so the bulb sits high enough that the gecko cannot touch the glass, and so the spot reads 90F at the surface. Start higher than you think you need. You can always lower the fixture, but you cannot undo a burn.
3. Check the socket material. Use a porcelain or ceramic socket. A plastic socket under a bulb that runs hot for twelve hours a day is a blackened socket and a failed bulb waiting to happen. If your fixture has a plastic fitting, replace it before you install the bulb.
4. Place the probe on the basking surface. The probe belongs in the warm zone, secured to the rock, not floating in the middle of the enclosure and not under a hide. A probe in the wrong place reads the wrong temperature and the thermostat will follow the wrong number.
5. Verify with a second thermometer. Your infrared thermometer and the thermostat probe should agree within a couple of degrees. If they do not, the probe is misplaced or the surface is uneven. Reposition the probe until they agree.
Then leave it running for a week before you trust it. On day one, measure the basking surface, the warm hide and the cool hide with the infrared thermometer at the same time of day. Check the same three points daily for a week, and again once the room temperature has swung through a full cycle. Any spot that drifts outside 88-95F needs a fixture height adjustment, not a thermostat tweak.
Two failure modes catch new keepers out. If the socket or bulb blackens, the fixture is undersized or the bulb is the wrong type for the socket, and the fix is hardware, not settings. If the bulb dims erratically or the output drops over time, the filament is degrading and it is time to replace it rather than to adjust the thermostat.
A final note on UVB. UVB is a separate concern from basking heat, and combining a halogen basking lamp with a UVB fixture is common and generally well regarded in keeper communities. Keep the two on separate timers so the UVB runs on its own schedule, and avoid adding a third bright source that would leave the animal with nowhere dark to hide.
Frequently Asked Questions
What kind of heat lamps do leopard geckos need?
Leopard geckos need one overhead basking heat source plus a thermostat. Most keepers use a 50W to 75W halogen-style spot bulb in a deep dome with a ceramic socket, run on a dimming thermostat, targeting 88-95F on the basking surface, 80-90F on the warm side and 70-75F on the cool side. A ceramic heat emitter or deep heat projector can cover the night period if the room gets cold.
Do leopard geckos need a basking lamp?
Yes. A basking lamp is the primary heat source in a leopard gecko enclosure. Without a defined warm spot, a gecko cannot thermoregulate properly, which leads to poor digestion and stunted growth. The lamp should always be controlled by a dimming or proportional thermostat rather than a simple on-off switch.
Is a 100W heat lamp too much for a leopard gecko?
Not necessarily. Wattage has to be matched to dome height, enclosure size and beam spread rather than judged on its own. A 100W bulb in a 40 gallon tank with a tall dome can be correct, while a 60W bulb in a shallow 10 gallon tank can overshoot. Measure the surface temperature with an infrared thermometer and adjust the fixture height until the basking spot reads 88-95F.
Do leopard geckos need a night heat lamp?
Usually not. Most leopard geckos are fine with a drop to the mid 60s overnight in a normally heated room, and a true dark night is better than a colored night bulb. If your room regularly falls below 65F, add a ceramic heat emitter or a deep heat projector that produces no visible light. Never use red, blue or purple bulbs to provide night heat.
Is 100 degrees too hot for a leopard gecko?
Yes, 100F on the basking surface is above the recommended range. Aim for 88-95F measured on the rock itself. If the surface is reading 100F, raise the dome, switch to a wider reflector beam, or drop to a lower wattage bulb rather than lowering the thermostat set point, since the surface is the value that matters.
What stresses out a leopard gecko?
The most common stressor in this context is lighting and heat that does not match natural conditions: colored night bulbs that prevent a dark night, a uniform warm floor with no gradient, a basking surface that is too hot, or an enclosure with nowhere shaded to retreat. A dimmable overhead basking spot, a genuine dark night and a clear gradient solve most of it.
The Best Basking Lamps for Leopard Geckos in 2026
The best basking lamps for leopard geckos are overhead bulbs that create one defined hot spot and are controlled by a dimming thermostat. Our pick for 2026 is the Fluker’s Repta-Clamp Lamp paired with a 60W to 75W basking bulb, because a clamp fixture you can reposition every week is worth more than a marginal gain in any single bulb.
For a complete kit with no assembly, the DOMICA fixture set gets you a ceramic socket and two bulbs in one order. For a 10 gallon starter tank, the Zoo Med 50W or 25W nano spot is the right size. For a cold room where the basking spot will not climb, step up to a 75W UVA reflector or a wide-beam bulb and recheck the surface with an infrared thermometer.
Whichever you choose, verify it before you trust it. Measure the surface, not the air, adjust the fixture height rather than the bulb, and give it a full week of readings before you call it set.
