Exo Terra Reptile UVB 150 T8 Tube

The Exo Terra Reptile UVB 150 Tube is a high-output T8 fluorescent lamp engineered for desert and arid-species keepers who need serious UVB performance. Replicating the intense UV radiation experienced by sun-exposed desert reptiles, this tube delivers UVB levels that match some of the harshest natural environments — making it the right tool for species with elevated UV requirements.

High UVB Output for Desert Species

Desert reptiles bask in direct, unfiltered sunlight for extended periods and require correspondingly high levels of UV radiation to thrive. This tube's very high UVB output mirrors those conditions within the vivarium, providing the intensity that species such as bearded dragons, uromastyx, and other arid-zone reptiles need to function properly. It is also well suited to set-ups where a dense or fine-mesh screen sits between the tube and the animal — dense screens can filter out up to 50% of UVB, and the higher output of this lamp compensates for that loss.

Vitamin D3 Synthesis and Calcium Metabolism

A high Vitamin D3 yield index is central to what this tube does for the animal. Adequate UVB exposure drives D3 photosynthesis in the skin, which in turn enables proper calcium absorption. Without sufficient D3, reptiles are at serious risk of metabolic bone disease — this tube is designed to remove that risk when used correctly and at the recommended distances.

Informed Setup with Detailed Packaging Data

Each tube ships with comprehensive technical information printed on the packaging, giving keepers everything they need to position and use it correctly. This includes a full spectral graph, a UV spectral graph, the Reptile Bulb Rating System classification, and distance-related data covering UVB output, D3 photosynthesis rates, Ferguson Zone guidance, and a full Exo Terra UVB chart. There is no guesswork involved in dialling in the correct placement.

Available in Multiple Sizes

The UVB 150 tube is available in a range of sizes to suit vivariums and terrariums of different scales. Longer tubes can span multiple enclosures side by side, making them practical for keepers running several set-ups under shared lighting. Select the appropriate size for your enclosure from the variant options on this page.

For keepers housing desert reptiles or working with screen-top enclosures where UVB penetration is a genuine concern, the Exo Terra Reptile UVB 150 Tube offers a straightforward, well-documented solution backed by clear setup data.
