Exo Terra Reptile UVB 150 Tube 15W 18in T8 UVB Lamp PT2395

The ET Reptile UVB 150 Tube 15W 18in (PT2395) is a high-output T8 fluorescent UVB tube designed for desert-dwelling reptiles that require intense UV exposure to thrive. Replicating the strong, direct sunlight of arid environments, this tube delivers a very high UVB output comparable to desert sunlight conditions — making it suited to species such as bearded dragons, uromastyx, and other basking reptiles with demanding UV requirements.

High UVB Output for Desert Species

Desert reptiles experience greater UV radiation than most other reptile groups, and their physiology reflects that — they require correspondingly high UVB levels in captivity to stay healthy. This tube is built to meet that demand, delivering the kind of UV intensity that encourages proper vitamin D3 photosynthesis, which in turn supports calcium absorption and helps prevent metabolic bone disease.

Suitable for Dense Screen Covers

If your vivarium uses a mesh or screen lid, UVB penetration can be significantly reduced — dense screen covers are known to filter out up to 50% of UVB rays. The high output of this tube means it remains effective even when mounted above such covers, making it a practical choice for keepers whose setups would otherwise compromise UVB delivery.

Vitamin D3 Synthesis and Keeper Confidence

• High Vitamin D3 yield index to support calcium metabolism
• Aids in the prevention of metabolic bone disease in captive reptiles
• Very high UVB output comparable to direct desert sunlight conditions
• 18-inch length suitable for placement across a range of vivarium sizes
• 15W T8 tube format, compatible with standard T8 fluorescent fittings

Detailed Packaging Information

The packaging provides keepers with a full spectral graph and UV spectral graph, alongside a reptile bulb rating system. Distance-related data is also included, covering UVB output, D3 photosynthesis rates, Ferguson Zone guidance, and a UVB chart — giving you everything you need to position the tube correctly and ensure your animal receives the right UV dose.

For keepers serious about UV provision for desert species, this tube takes the guesswork out of UVB husbandry and gives you a solid, well-documented lighting tool to build your setup around.
