The Exo Terra UVB100 emits optimal levels of UVB, similar to that of shady environments such as rain forests 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. BOX CONTAINS Light Tube

UVA rays stimulate appetite, activity and reproductive behavior. provides necessary UVB rays for optimal calcium metabolism. Optimal levels of UVB. Ideal for all tropical and sub-tropical reptiles.
