Exo Terra Reptile UVB 150 Compact Lamp 13W | Desert Reptile UVB Bulb

The ET Reptile UVB 150 Compact Lamp 13W (PT2188) is a high-output UVB compact bulb designed specifically for desert-dwelling reptiles. These species bask under intense, direct sunlight in the wild and require UVB levels that match those conditions — this lamp delivers exactly that, replicating the solar radiation experienced in arid and semi-arid environments.

High-Output UVB for Desert Species

Desert reptiles — including bearded dragons, uromastyx, and many agamids — are among the most UV-exposed animals on the planet. This lamp produces a very high UVB output comparable to direct desert sunlight, supporting the UVI levels these species need to thrive. It replaces the former Repti Glo 10.0 with an updated spectrum.

Vitamin D3 Synthesis and Calcium Metabolism

The bulb carries a very high D3 yield index, meaning it actively drives vitamin D3 photosynthesis in the skin. Adequate D3 is essential for calcium absorption, and without sufficient UVB exposure, reptiles risk metabolic bone disease. This lamp directly addresses that risk for keepers of high-UV species.

Effective Range and Screen Penetration

• Effective UVB output up to 50 cm (20 inches) from the lamp
• High enough output to compensate for dense mesh or screen covers, which can filter out up to 50% of UVB rays
• Recommended for terrariums where screen coverage would otherwise compromise UVB penetration

Compact Format

The compact design makes this bulb compatible with a wide range of standard reptile luminaires and fixtures. For keepers who want to supplement visual light output, it can be paired with a natural daylight bulb to create a more complete lighting environment.

For any keeper maintaining desert reptiles and wanting confidence that UVB provision is not a limiting factor in their animal's health, the ET Reptile UVB 150 Compact Lamp 13W is a straightforward, well-specified choice.
