The Exo Terra Reptile UVB100 emits optimal levels of UVB, similar to that of shady environments such as rainforests or other tropical locations. Reptiles living in these habitats receive moderate UV radiation due to climatological conditions (fairly high humidity, changes in weather, etc) that prevent unfiltered sunlight from reaching the reptile's basking site. The optimal Vitamin D3 yield index ensures vitamin D3 photosynthesis to aid calcium absorption and prevent metabolic diseases. The longer sizes can be placed on multiple terrariums.

The packaging includes all necessary information: Full Spectral Graph, UV Spectral Graph, Reptile Bulb Rating System and distance-related information like UVB output, Photosynthesis, Ferguson Zones and Exo Terra Reptile UVB Chart.
