Exo Terra Reptile UVB 150 Tube 14W 15in T8 Lamp | PT2394

The ET Reptile UVB 150 Tube 14W 15in (PT2394) is a high-output T8 fluorescent UVB lamp designed for desert-dwelling reptiles that require intense UV exposure. With a UVB output level comparable to direct desert sunlight, this tube is suited to species that bask in open, arid environments and demand more UV radiation than woodland or tropical reptiles. It is also a practical choice where dense mesh or screen lids are in use, as these can block up to 50% of UVB rays — the higher output compensates for that loss and ensures sufficient UVB still reaches your animals.

Desert-Level UVB Output

Desert reptiles sit at the higher end of Ferguson Zone requirements, spending extended periods under intense, direct UV radiation in the wild. This tube replicates that intensity, making it appropriate for species such as bearded dragons, uromastyx, and other arid-zone lizards that need sustained UVB exposure to thrive in captivity.

Vitamin D3 Synthesis and Calcium Absorption

The tube carries a high Vitamin D3 yield index, supporting the photosynthesis of D3 in the skin. Adequate D3 is essential for calcium metabolism — without it, reptiles are at serious risk of metabolic bone disease. Running this tube at the correct distance and duration provides a key line of defence against nutritional deficiencies that are common in captive desert species.

Suitable for Screen-Covered Vivariums

Dense screen or mesh tops can significantly reduce UVB penetration before it even reaches the animal. The elevated output of this tube makes it a reliable option in setups where that filtration effect is unavoidable, helping to ensure your reptile still receives a meaningful UV dose throughout the day.

Packaging and Technical Data

• Full spectral graph and UV spectral graph included on packaging
• Reptile Bulb Rating System reference provided
• Distance-related UVB output and photosynthesis data included
• Ferguson Zone guidance and UVB chart included for correct placement

Having accurate setup data on the packaging means keepers can position this tube correctly from day one, without guesswork. For those running multiple vivariums, the 15-inch length is worth checking against your enclosure dimensions, as longer T8 tubes in the range can span across more than one terrarium.
