Product Information

Why Is UVB Light Essential?

In its natural environment, a reptile has exposure to direct light from the sun, which as well as being composed of the visual light that we are familiar with, also has a significant content of ultra-violet light.This UV energy is an important factor, as it drives a chemical reaction in the skin, which results in the formation of vitamin D3, without which calcium metabolism cannot occur correctly, and the skeleton of the animal cannot develop correctly.

When a captive reptile is not exposed to direct sunlight, then the resulting lack of vitamin D3 can cause the bones to become weak and misshapen. Other hard structures, such as scales, claws, and the carapace of tortoises or turtles would also be adversely affected without sunlight.

These lights will need to be used with a T8 controller, such as the Arcadia light controller and a reflector (optional) to almost double the light output. For the maximum enjoyment of your terrarium / vivarium we recommend that you replace your Reptile Systems light at least once a year.
