Best Reptile & Amphibian Habitat Lighting AI pick
Chosen by an AI model from its trained knowledge, with its reasoning.
AI pick (line): Arcadia ProT5 UVB Kit
This kit pairs a high-output T5 linear UVB tube with a reflector and controller, giving strong and even UVB across a basking zone, which most experienced keepers prefer to coil bulbs.
Not for: Keepers of tiny nano enclosures or low-UV crepuscular species that only need a weak strip.
AI picks by need
For alternative T5 UVB tube
Zoo Med ReptiSun T5 HO (line)
This T5 HO linear UVB is widely stocked and a common substitute for Arcadia in desert and forest strengths.
Not for: People reusing old T8 fixtures, because T5 tubes need a T5 ballast.
For basking heat
Arcadia Deep Heat Projector (line)
This emits infrared-A and infrared-B heat without light, which suits nighttime heat or a supplemental warm zone.
Not for: Day-active baskers, which need a bright halogen basking light as their main heat.
What the AI looks for in Reptile & Amphibian Habitat Lighting
- Linear tube over coil
- Use a T5 HO linear UVB tube, about half to two-thirds the enclosure length, over a compact coil bulb. Linear tubes create a wide, even UV gradient, while coils give a small and inconsistent hotspot.
- UV strength by species
- Match the species' Ferguson zone. Desert baskers such as bearded dragons typically need about 10–14% tubes. Forest and crepuscular species need about 5–7%. Too little UVB causes bone disease, and too much at close range can damage eyes and skin.
- Mesh and distance
- Mount the tube at the manufacturer's recommended distance, and account for screen mesh blocking a large share of UVB. UVB output drops sharply with distance and through mesh.
- Replacement interval
- Replace T5 UVB tubes about every 12 months, or sooner if a UV meter shows they have dropped. UVB output declines long before the visible light dims.
- Heat source is separate
- Provide basking heat with halogen flood lamps controlled by a thermostat or dimmer. UVB tubes are not heaters. T5 UVB tubes provide almost no usable heat.
Brands that matter
- Arcadia: Reference brand for T5 UVB tubes and kits.
- Zoo Med: ReptiSun UVB and a broad range of heat lamps.
- Exo Terra: Fixtures and basking lamps.
What to avoid
- Compact coil UVB bulbs as the only UV source for desert baskers
- Colored nighttime bulbs, which disrupt sleep
- Unregulated heat lamps without a thermostat or dimmer
Questions
Do leopard geckos need UVB?
They can survive without it if given D3 supplements, but low-level UVB (around 5–7%) is now widely recommended.
