Exo Terra Reptile UVB 150 Compact Lamp 26W | Desert UVB Bulb PT2189

The ET Reptile UVB 150 Compact Lamp 26W (PT2189) is a high-output UVB bulb designed specifically for desert reptile setups. Built to replicate the intense UV radiation levels found in arid environments, it delivers UVB output comparable to direct desert sunlight — making it the right choice for species that bask hard and require strong D3 synthesis to stay healthy.

High-Output UVB for Desert Species

Desert-dwelling reptiles experience some of the highest UV exposure of any reptile in the wild. This lamp matches that intensity, providing a very high UVB output that supports the elevated requirements of tortoises, uromastyx, bearded dragons, and similar species. A high Vitamin D3 yield index ensures effective D3 photosynthesis, which in turn drives calcium absorption and helps prevent metabolic bone disease.

Effective Range and Screen Cover Performance

• Effective UVB penetration up to 50 cm (20 inches)
• Recommended for use in terrariums with dense screen covers, which can block up to 50% of UVB output
• The elevated UVB output compensates for screen filtration, ensuring adequate UV reaches your animal

Updated Spectrum

This lamp represents a new spectrum formulation — it replaces the former Repti Glo 10.0 and improves on it. For keepers who previously relied on that bulb, this is the current equivalent. For optimal visual light output within the vivarium, it can be paired with a compatible natural light bulb.

Compact Format

At 26W in a compact form factor, this bulb fits standard compact lamp fixtures without requiring a dedicated linear tube setup. That makes it a practical option for smaller desert vivarium builds or for keepers who want strong UVB output without the footprint of a tube system.

For any desert reptile keeper who takes UV provision seriously, the ET Reptile UVB 150 Compact Lamp 26W delivers the output levels these animals genuinely need — not a compromise, but a lamp built around their biology.
