2.0 Compact: The Exo Terra natural light 2.0 is a general light source with high visual light output and a very high colour rendering index (CRI), but a lower UVB radiation. This bulb is suitable for snakes, all amphibians (frogs, toads and salamanders) and nocturnal animals. Plants will thrive under this light as well. It is also a perfect complementary light to a UVB bulb to boost visual light. 5.0 Compact: The Exo Terra Reptile Light 5.0 has a moderate to high UVB output, similar to that of shady environments such as rain forests and other tropical locations. Reptiles living in these habitats receive less UV radiation because of the many climatological conditions (fairly high humidity, changes in weather, etc) that prevent direct sunlight from reaching them or their basking sites. 10.0 Compact: The Exo Terra Reptile Light 10.0 has a very high UVB output similar to that associated with desert environments. Desert locations receive more direct sunlight than any other because of fewer clouds, less air humidity, and no plants or trees to provide shade. Therefore desert reptiles are more exposed to UV radiation than any other type of reptile. This bulb can also be used on screened terrariums or terrariums with dense screen covers to ensure UVB penetration. Dense screens can filter out up to 50% of the UVB rays. Intense Compact: The Exo Terra Reptile UVB200 emits the ideal UVB spectrum for optimal Vitamin D3 photosynthesis. The Reptile UVB200 Bulb is especially designed to simulate conditions for reptiles with very high UV requirements, like diurnal reptiles from desert environments. These areas receive direct unfiltered sunlight with high levels of UVB. The significantly high Vitamin D3 yield index results in increased vitamin D3 photosynthesis to aid calcium absorption and prevent metabolic diseases. The extended UVB penetration makes this bulb the ideal choice for taller terrariums or terrariums with denser screens.
