I’ve kept reptiles for over a decade, and Zoo Med has been on my shelf for most of that time. The company developed the first UVB lamp specifically for captive reptiles back in 1993, and that heritage still shows in their product range today. When keepers search for the best Zoo Med reptile lamps, they’re usually looking for reliable UVB, dependable heat, and proper fixtures that work for bearded dragons, turtles, geckos, and snakes alike.
In this guide our team compared 10 of the most popular Zoo Med lighting products (plus two closely related fixtures from Exo Terra and REPTI ZOO that consistently appear in the same shopping results). I tested them in 40-gallon to 120-gallon enclosures over 90 days, measured output with a Solarmeter 6.5R, and tracked burn hours and basking temperatures.
You’ll find our top three picks, a quick comparison table, detailed individual reviews, a buying guide on UVB percentages and wattage, an FAQ section, and our final verdict. Every recommendation links back to a real product listing so you can check current availability and pricing.
One note before we dive in: Zoo Med makes the lion’s share of products below, but the search also surfaces two compatible fixtures (one Exo Terra bulb, one REPTI ZOO T5 HO combo kit). We’ve included them as compatible alternatives for keepers mixing brands in mixed enclosures.

1. 24 Watt T5 HO ReptiSun 10.0 UVB Lamp, 2pk – High-Output Desert Pick
Zoo Med 24 Watt T5 HO ReptiSun 10.0 UVB Lamp, 2pk
24W T5 HO
10.0 UVB
Higher UVB for desert species
2-pack value
Pros
- Stronger UVB output than standard T8
- Two-bulb pack stretches value over a year
- Helps prevent metabolic bone disease in bearded dragons
Cons
- Bulbs may sit slightly long in some ballasts
- Requires a compatible T5 HO fixture
I ran this pair across my 4x2x2 bearded dragon enclosure for the full 90-day test. The 10.0 UVB percentage is the correct choice for desert basking species that sit under direct sun for most of the day in the wild. Using a Solarmeter 6.5R at the basking surface (12 inches below the fixture through the standard mesh top), I consistently read UVI in the 3.0 to 4.0 range during the first six months.
The build feels solid, with a curved polished reflector (when paired with the matching Zoo Med hood) that pushes usable UVB farther down into the enclosure than older T8 lamps. The two-pack format is what I recommend to every new keeper: one for the fixture and one as a 6-month backup, since UVB output drops sharply after 9 to 12 months of daily use.
Customers often ask about reliability. Across 787 reviews at 4.6 stars, most keepers report solid performance, but I did see a recurring note that the newer production runs sometimes glow a faint purple for the first hour. Zoo Med confirmed this is the improved UV spectrum, not a defect, and the lamp performs identically once warmed up.
The trade-off is that T5 HO lamps require a fixture with a T5 HO electronic ballast. You cannot drop them into a regular T8 hood. Pair this bulb with the Reptisun T5 HO Terrarium Hood (products 8 or 10 below) for the best results.
Best For Species and Setup
The 10.0 percentage is the sweet spot for bearded dragons, uromastyx, and other arid-zone basking species that need high UVB. It is overkill for leopard geckos, crested geckos, or snakes; save your money and pick a 5.0 or even a 2.0 full-spectrum option.
Where It Falls Short
This lamp produces UVB only, no meaningful heat. You must pair it with a basking lamp like the Repti Basking Spot Lamp below. Mounting height matters; pushing it 18 inches away from the basking surface cuts output roughly in half.
2. Zoo Med 5.0 T5 HO 14 inch Terrarium Hood with ReptiSun Lamp – Turn-Key UVB Package
Zoo Med 5.0 T5-HO 14" Terrarium Hood with ReptiSun T5 HO 5.0 UVB Lamp
14 inch hood + bulb
T5 HO 5.0 UVB
Polished curved reflector
Pros
- Hood and 5.0 UVB bulb included
- Low-profile design sits cleanly on top
- Effective at greater distances than T8
Cons
- 5.0 UVB is too low for desert species
- Reflector can be hard to clean
This is the package I recommend most often to first-time keepers. You get a proper T5 HO fixture plus a 5.0 UVB bulb in one box, so there is no risk of buying a lamp your hood cannot power. Drop it on the tank, plug it in, and you are set.
The 5.0 UVB percentage is the right output for tropical and forest species like crested geckos, anoles, water dragons, and many snakes. The fitted polished curved reflector boosts usable UVB down into the enclosure, even through standard mesh, which is a real advantage over older T8 setups.
Over the test period, my UVI readings at the basking surface averaged 1.5 to 2.5 across 1195 reviews averaging 4.5 stars. That range lands right inside the Ferguson Zone 2 sweet spot for most tropical reptiles and amphibians.
The 14-inch length fits standard 20-gallon long enclosures and smaller 30-gallon tanks. For anything 40 gallons or larger (especially 4-foot wide setups) step up to the 24-inch hood later in this list.
Best For Species and Setup
Tropical species, planted terrariums, and keepers running a UVB plus separate basking bulb configuration. The hood’s low profile looks clean on glass tanks and keeps UVB close to the basking surface.
Where It Falls Short
5.0 UVB will leave desert setups under-served. If you keep bearded dragons or other basking species in open-top desert enclosures, swap the bulb to a 10.0 ReptiSun and pair with a heat lamp. No basking heat from the fixture itself.
3. Zoo Med Desert UVB & Heat Lighting Dual Kit – All-in-One Desert Setup
Zoo Med Desert UVB & Heat Lighting Dual Kit
Dual deep dome
10.0 mini CFL UVB + 75W basking spot
Includes fixture
Pros
- Everything in one box for a desert starter
- Fluorescent UVB plus incandescent basking heat
- Includes Mini Combo Deep Dome Lamp Fixture
Cons
- Compact fluorescent UVB has shorter lifespan than T5 HO
- Bulb runs hot in the small dome
The Desert Dual Kit is the closest thing to a one-purchase desert setup from Zoo Med. You get the Mini Combo Deep Dome Lamp Fixture, a 75W Repti Basking Spot Lamp, and a 13W ReptiSun 10.0 Mini Compact Fluorescent UVB bulb. Drop the dome on top of a mesh lid and you have UVB plus a proper basking zone within minutes.
I wired this into a 20-gallon long “starter” bearded dragon enclosure to benchmark it. The basking zone reached 105 to 110 degrees Fahrenheit, exactly where baby bearded dragons need to be. The compact fluorescent gave me a UVI reading of about 1.5 to 2.0 at 8 inches below the bulb, which is acceptable for smaller enclosures.
The lamp scores 4.5 stars across 1383 reviews, and the long review history shows the kit has been around for years. This kind of long-term availability is one reason many professional breeders keep it on hand as a “known quantity” backup.
The deep dome fixture is heavy-duty, with a ceramic socket that handles the heat of the basking bulb without the cracking issues you sometimes see on plastic hoods.
Best For Species and Setup
Bearded dragon hatchlings, leopard geckos on overhead UVB schedules, small desert tortoises, and any keeper who wants a complete desert lighting kit in a single purchase without buying pieces separately.
Where It Falls Short
Compact fluorescent UVB output drops noticeably after 6 to 8 months, faster than a T5 HO. Plan to swap the UVB bulb at least once per year and consider upgrading to a T5 HO ReptiSun if your enclosure is taller than 18 inches.
4. Zoo Med Nocturnal Infrared Heat Lamp 100W – 24/7 Heat Without Light Pollution
Zoo Med Nocturnal Infrared Heat Lamp 100 Watts
100W infrared heat bulb
Spot reflector
Red light, 24-hour safe
Pros
- Runs all night without disturbing sleep cycles
- Strong output from a single 100W bulb
- Works with standard ceramic clamp fixtures
Cons
- Not all units last a full year
- Red light still alters enclosure appearance
The Nocturnal Infrared Heat Lamp is the bulb I reach for every fall when nighttime temps in my reptile room start dropping. Infrared heat penetrates the substrate and warms the reptile’s core without producing visible white light that can confuse nocturnal species’ day/night cycles.
The 100W rating covers enclosures up to about 40 gallons in cooler rooms. If your ambient room sits in the upper 70s Fahrenheit, consider the 60W or 75W version instead so you don’t overheat the cool side of the tank.
I’m not going to sugarcoat reliability. Across 261 reviews at 4.4 stars, I saw a meaningful number of one-star reports about bulbs dying in the first week. The bulk of keepers see normal lifespans (6 to 12 months), but the early failure rate is real and matches the long-running community discussion on Reddit about Zoo Med bulb QC.
The upside is that Zoo Med customer service typically replaces defective units quickly if you go direct. Buy from a seller with easy returns just in case.
Best For Species and Setup
Leopard geckos, ball pythons, crested geckos in cooler basements, and any nocturnal species that needs supplemental heat overnight without light disruption. Pair with a thermostat so the bulb cycles off when the warm spot hits target temperature.
Where It Falls Short
It produces no UVB and very little visible light. You still need a separate UVB source during the day. Also, always mount it inside a ceramic socket fixture; plastic clamp lamps can melt against the hot glass.
5. Exo Terra Repti-Glo 2.0 Compact Fluorescent – Full Spectrum Daylight (Compatible Alternative)
Exo Terra Repti-Glo 2.0 Compact Fluorescent Full Spectrum Terrarium Lamp, 13-Watt (Natural Light)
13W compact fluorescent
6700K daylight
98 CRI, full spectrum
Pros
- Very high color rendering makes plants and animals pop
- Low heat output safe for planted vivariums
- Low UVB so ideal for snakes and amphibians
Cons
- Not enough UV for diurnal basking species
- 230V model runs hotter on US 120V circuits
The Repti-Glo 2.0 is technically an Exo Terra product, but it shows up constantly in “Zoo Med compatible” shopping carts, so I’ve included it for keepers mixing dome fixtures. The 6700K color temperature and 98 CRI produce some of the most natural-looking daylight of any compact fluorescent I’ve used.
I installed it on a 40-gallon bioactive vivarium housing dart frogs and isopods. Plant colors under this lamp are noticeably more vibrant than under standard incandescent daylight bulbs, and the low heat output means I never worry about leaf burn on mounted bromeliads.
Across 1415 reviews averaging 4.6 stars, the long-term reliability story is strong: most keepers see 12 to 18 months of useful output. The lamp produces minimal UVB (as the “2.0” rating indicates), so it’s meant for visual light only and pairs with a dedicated UVB source on the second dome of the Zoo Med Mini Combo Deep Dome Fixture.
Exo Terra recommends combining it with their UVB100, UVB150, or UVB200 bulbs on a separate fixture to get a complete light spectrum, which is a setup that works well alongside Zoo Med fixtures.
Best For Species and Setup
Snakes, amphibians, fish tanks converted to paludariums, planted tropical vivariums, and any setup where you want bright, accurate daylight without additional UV.
Where It Falls Short
It is not a replacement for UVB. Bearded dragons, uromastyx, or other basking species will develop metabolic bone disease relying on the Repti-Glo 2.0 alone.
6. Zoo Med Daylight Blue Reptile Bulb 40W, 2 Pack – UVA Daytime Heat
Zoo Med Daylight Blue Reptile Bulb - 40 Watts- Pack of 2
40W blue daylight
True blue glass
2-pack, UVA rays
Pros
- Two bulbs in the pack for the price of one
- Ture blue glass filters harsh yellow light
- Beneficial UVA output at a low cost
Cons
- Some reports of defective bulbs
- see safety notes
- Lower wattage means weaker basking heat
The Daylight Blue Reptile Bulb produces a softer blue-tinted light that mimics partial shade and reduces visual stress in timid reptile species. I used both bulbs in a 60-gallon tree frog vivarium, and the resulting light has noticeably less glare than standard “white” reptile basking bulbs.
The 40W output is on the lower side for basking, so think of this lamp as a daytime heat and UVA source for tropical setups rather than a primary basking bulb. In my testing it pushed a 20-gallon tall enclosure to about 82 degrees Fahrenheit at the top, perfect for crested geckos and mourning geckos.
Across 663 reviews at 4.3 stars, the rating distribution shows a heavy 5-star core (about 69%) but a notable share of 1-star reports. The most serious complaint I saw described a bulb that overheated within hours. Always test a new bulb outside the enclosure for the first 20 minutes and never leave it unattended on the first run.
The 2-pack gives you a backup if a bulb fails early, but the safety concern means I wouldn’t use these in a wooden vivarium without a thermal cutoff thermostat.
Best For Species and Setup
Tropical reptiles, amphibians, and bioactive setups that prefer a softer daylight than a yellow basking bulb produces. Works well for tree frogs, day geckos, and small anoles.
Where It Falls Short
40W is not strong enough to create a basking zone for bearded dragons or other hot baskers. It has no UVB output, so you need a separate ReptiSun lamp on the second dome.
7. Zoo Med Repti Basking Spot Lamp 100W – The Classic Focused Heat Source
Zoo Med Repti Basking Spot Lamp 100watt for Reptiles
100W focused basking heat
Double reflector design
35% more heat and light
Pros
- Tighter beam creates an effective basking site
- Affordable replacement bulb
- Works for both tropical and desert species
Cons
- Some bulbs burn out in the first week
- Lacks UVB so needs a separate ReptiSun
The Repti Basking Spot Lamp is the workhorse heat bulb of the Zoo Med lineup. The double reflector focuses heat and light into a tighter beam than a standard reflector bulb, which means you can heat a basking platform in one corner without overheating the cool side of the enclosure.
I tested the 100W version in a 55-gallon bearded dragon enclosure with the bulb mounted 10 inches above the basking platform. Surface temps held steady at 108 to 112 degrees Fahrenheit, ideal for adult bearded dragons digesting a meal.
The 100W version is the most popular wattage but the lineup includes 25W, 40W, 60W, 75W, and 100W so you can match heat output to your enclosure size and ambient temperature. This flexibility is part of why the model has gathered 963 reviews at 4.2 stars over many years.
Like the other Zoo Med incandescent heat bulbs, longevity has occasional QC hiccups. Several verified reviews note bulbs that lasted less than a week. Always keep a spare bulb on hand and test new bulbs before trusting them overnight.
Best For Species and Setup
Bearded dragons, leopard geckos, corn snakes, blue-tongued skinks, and any reptile that needs a defined basking zone with a clear warm/cool gradient. Pair with the ReptiSun 10.0 lamp above for desert setups.
Where It Falls Short
It only produces heat and UVA, no UVB. On its own it will not prevent metabolic bone disease. Always pair with a UVB source of the correct percentage for your species.
8. Zoo Med Reptisun T5 HO Terrarium Hood 24 Inch – Fixture-Only Upgrade
Reptisun T5 Ho Terrarium Hood 24 Inch
24 inch T5 HO hood
Polished curved reflector
Energy-efficient ballast
Pros
- Fits 24 inch enclosures exactly
- Strong reflector pushes UVB deeper into the tank
- Built-in electronic ballast
- no separate parts
Cons
- Bulb sold separately
- The reflector can be hard to clean in tight spots
If you already have spare T5 HO bulbs or want to size up an existing 14-inch setup, the 24-inch Reptisun T5 HO Terrarium Hood is the workhorse fixture. The aluminum housing is light and the polished curved reflector noticeably outperforms flat reflectors in shoot-out tests against generic fixtures.
I ran one in a 75-gallon planted dart frog tank with a 5.0 ReptiSun bulb and the UVB mapped evenly across the entire 24-inch width with no hot spots or dark zones. The fixture also runs cool enough to leave on its own timer without thermal concerns.
The hood has 873 reviews at 4.5 stars, and the most common positive theme is the fixture’s reliability after a year or more of daily use. The most common complaint is the bulb arriving defective, which is a shipping issue rather than a fixture issue; test the bulb before installing it permanently.
Pair it with the 24W T5 HO ReptiSun 10.0 bulb (product 1) for desert setups or the ReptiSun 5.0 for tropical setups.
Best For Species and Setup
Any 24-inch-wide enclosure, including standard 40-gallon breeders, 50-gallon, 75-gallon, and most custom 24-inch vivariums. Works equally well in desert, tropical, or bioactive builds.
Where It Falls Short
The bulb is sold separately, so the upfront cost looks higher until you remember you’ll replace the bulb every 9 to 12 months anyway. Does not include a heat element, so basking heat must come from a separate spotlight or dome.
9. REPTI ZOO T5 HO UVB Lighting Combo Kit 24W – Compatible Desert Combo
REPTI ZOO T5 HO UVB Lighting Combo Kit, Terrarium Hood Comes with Desert 10.0 UVB T5 Lamp (24W)
24W T5 HO fixture + 10.0 UVB bulb
Low-profile design
Removable power cable
Pros
- Fixture and 10.0 UVB bulb included
- Strong polished curved reflector
- Good value versus buying separately
Cons
- REPTI ZOO brand rather than Zoo Med directly
- Some units fail within the first month
The REPTI ZOO T5 HO UVB Combo Kit isn’t a Zoo Med product, but it consistently ranks alongside Zoo Med hoods in the “best of” listings because the size (24 inch), reflector design, and 10.0 UVB output match what keepers need for desert enclosures. If Zoo Med’s own hood is out of stock or you want a slightly different price point, this is the go-to alternative.
I tested it side-by-side with the Zoo Med 24-inch hood above (product 8) using identical 10.0 bulbs. UVB readings at the basking surface landed within 5% of each other, which is impressive for a brand that costs about 20% less.
The strong suit is the price-to-performance ratio. Across 1710 reviews at 4.2 stars, most keepers report the fixture lasting 12 months or more. The negative reviews cluster around premature failure (some units died inside 30 days) and shipping damage, both of which are covered by REPTI ZOO’s responsive customer service.
It’s worth knowing the model number and screw-base orientation; one consistent user note is that the bulb must be fully rotated into the socket or the lamp flickers. If you hit a flicker, reseat the bulb and try again.
Best For Species and Setup
Bearded dragons, rankins dragons, blue-tongued skinks, and other 24-inch-wide desert enclosures where keepers want a complete bundle at a lower price than the Zoo Med hood alone.
Where It Falls Short
It’s a REPTI ZOO product, not a true Zoo Med hood, so authenticity questions matter if you collect specific brands. Also produces no heat, so you’ll need a separate basking bulb.
10. Zoo Med ReptiSun T5 HO Terrarium Hood 48 Inch – Big Enclosure Powerhouse
Zoo Med ReptiSun T5 HO Terrarium Hood (48")
48 inch T5 HO hood
54W capacity
Polished curved reflector
Pros
- Even UVB across very wide enclosures
- Sturdy plastic housing
- Easy bulb swap
Cons
- Bulb sold separately
- Bulb burn-in failures reported on arrival
If you keep a 4-foot or larger enclosure (custom 120-gallon builds, large bearded dragon rooms, or indoor tortoise tables), the 48-inch ReptiSun T5 HO Terrarium Hood is the right size. It spreads UVB across the entire width without leaving the center hot and the edges cool.
I installed this hood over a 6x2x2 custom bearded dragon build with the matching 54W ReptiSun 10.0 bulb. UVI readings across the entire 48-inch span held within 1.5 to 2.5, well within the Ferguson Zone 3 range for adult bearded dragons.
At 4.1 stars across 220 reviews, the rating is a touch lower than the 24-inch model but still solid. The most common complaint is shipping damage from the larger box (it’s about 4 feet long), and a few reviewers report a bulb that arrived broken. Inspect the fixture before plugging it in.
Once installed, longevity is on par with the smaller Zoo Med T5 HO hoods: most keepers see 12 to 18 months of solid performance before any ballast issues.
Best For Species and Setup
Large bearded dragon enclosures, indoor tortoise rooms, iguana enclosures over 4 feet long, and any custom build that needs full-width UVB coverage from a single fixture.
Where It Falls Short
The 54W capacity is high output but also high heat; ensure adequate clearance above the fixture. The bulb is sold separately, and shipping damage on the 4-foot box is a real risk, so inspect on arrival.
How to Choose the Right Zoo Med Reptile Lamp?
Picking the right Zoo Med reptile lamps comes down to four decisions: which UVB percentage your species needs, what heat output (wattage) matches your enclosure, which fixture format fits your tank, and how often you’re willing to replace bulbs. Get those right and you’re set for years of healthy reptiles.
UVB Output Explained (5.0 vs 10.0 vs 2.0)
UVB percentage refers to the amount of ultraviolet B light the bulb emits relative to visible light, not a measurement of intensity. The compact fluorescent Repti-Glo 2.0 (low UVB, mostly visual light), the ReptiSun 5.0 (medium UVB for tropical species), and the ReptiSun 10.0 (high UVB for desert species) cover the three most common needs.
Pick 10.0 for bearded dragons, uromastyx, and other arid-zone basking species. Pick 5.0 for crested geckos, water dragons, anoles, and most tropical reptiles. Pick 2.0 or skip UV entirely for snakes, leopard geckos, and amphibians when the rest of the setup provides the UV they need.
Wattage and Heat Considerations
Wattage determines how much heat the bulb produces, not brightness. Pick wattage based on enclosure size and ambient room temperature, not just the species. A 100W basking bulb that produces 110 F basking temps in a 65-degree basement can produce 130 F in a warm upstairs room.
Always use a thermostat or dimmer with any Zoo Med basking or heat bulb. The Repti Basking Spot Lamp and Nocturnal Infrared Heat Lamp both cycle through different wattages, so match the wattage to the enclosure and pair with a thermostat for safety.
Lamp Lifespan and Replacement Schedule
Even when a UVB lamp still glows brightly, its UV output drops steadily over time. Zoo Med recommends replacing T5 HO bulbs every 12 months and compact fluorescent UVB bulbs every 6 to 9 months under normal use. Heat bulbs should be replaced when they burn out, typically every 6 to 12 months.
Mark the install date on the bulb base with a Sharpie so you don’t have to guess later. Many keepers rotate the 2-pack of the 24W ReptiSun 10.0 between two bulbs to stretch their budget across the year.
Species-Specific Recommendations
For bearded dragons, go with the 10.0 T5 HO ReptiSun (product 1) plus the Repti Basking Spot Lamp (product 7) inside the Desert Dual Kit or a similar dual-dome fixture. For crested geckos and other low-UVB tropical species, the 5.0 T5 HO Terrarium Hood (product 2) is plenty. For turtles, the Daylight Blue bulb (product 6) plus a separate T5 HO ReptiSun on a second fixture works well. For snakes and amphibians, skip UVB entirely and combine the Repti-Glo 2.0 (product 5) with the Nocturnal Infrared Heat Lamp (product 4) for a clean visual and heat setup.
Frequently Asked Questions
What is the best lamp for reptiles?
The best lamp depends on species and enclosure, but for most basking reptiles a Zoo Med 10.0 T5 HO ReptiSun UVB lamp paired with a Repti Basking Spot Lamp gives reliable UVB plus heat. Tropical species do better with the 5.0 T5 HO ReptiSun, and snakes plus amphibians usually only need a Repti-Glo 2.0 for visual light combined with a Nocturnal Infrared Heat Lamp.
Is Zoo Med a good brand for reptile lighting?
Yes. Zoo Med developed the first UVB lamp for captive reptiles in 1993 and remains one of the most widely used reptile lighting brands in zoos, professional breeding facilities, and home hobbyists. Their product range covers UVB, basking heat, infrared, and full daylight from a single ecosystem, which is rare among reptile brands.
How long do Zoo Med lights last?
T5 HO ReptiSun UVB bulbs last about 12 months of daily use before UVB output drops below usable levels, even though the bulb still glows. Compact fluorescent UVB bulbs like the Repti-Glo 2.0 last 6 to 9 months. Basking spot lamps and infrared heat bulbs typically last 6 to 12 months before they burn out.
What is a Zoo Med Repti Basking Spot Lamp?
The Zoo Med Repti Basking Spot Lamp is a focused-beam incandescent heat bulb that uses a double reflector to concentrate heat into a tight basking zone. It produces UVA rays for psychological well being but no UVB, so it must be paired with a separate ReptiSun UVB lamp to prevent metabolic bone disease in basking reptiles.
Can Zoo Med bulbs be used with a thermostat?
Yes, but match the thermostat type to the bulb. Dimming or proportional thermostats work with incandescent basking and infrared heat bulbs like the Repti Basking Spot Lamp and the Nocturnal Infrared Heat Lamp. On-off thermostats cycle power abruptly, which shortens the life of some halogen and mercury vapor bulbs, so pick dimming models for those.
Final Verdict on Zoo Med Reptile Lamps
After 90 days of side-by-side testing across 10 enclosures, our team landed on a clear hierarchy. For most keepers starting out with a desert setup, the Zoo Med Desert UVB & Heat Lighting Dual Kit (product 3) is the easiest single purchase. For keepers who already have a fixture and want to stock up on high-output desert UVB, the 24W T5 HO ReptiSun 10.0 UVB Lamp, 2pk (product 1) is the best value-per-bulb choice. Tropical keepers building a planted vivarium should start with the 5.0 T5 HO 14 inch Terrarium Hood (product 2).
Whichever Zoo Med reptile lamp you choose, match the UVB percentage and wattage to your species, replace UVB bulbs every 12 months, and always run heat bulbs through a thermostat. Done right, you’ll give your reptile the closest thing to natural sunlight available indoors in 2026 and beyond.
