Without the sun’s energy, all life on earth would cease to exist. It is by the sun’s energy that all life forces are driven. Although the sun and its light are very complex, there are only three elements of light that are important and easily reproducible for reptile husbandry: ultraviolet light, visible light and infrared light. In order to create these three biological aspects of sunlight artificially, Exo Terra has developed several specialized lights to be used in the natural terrarium or aqua-terrarium setting. It is important to know that it is almost impossible to accommodate all of these needs in a single light source, a combination of different light sources is necessary in most cases. The table below will help you make the right lighting choice.
