UVB: reptiles need UVB light for vitamin D production and calcium formation. Without UVB, reptiles can get bone disease through metabolic disorders in 6 months or in a shorter period of time. UVA: reptiles and amphibians can see things people don't see. UVA light is the part of the rainbow colors that reptiles can see. UVA light helps to increase the overall activity level of reptiles, their appetite and their reproduction behaviour. Without UVA light, they are colour-blind. Ideal for large terrariums or vivariums with the following reptiles: tropical lizards (green iguanas, taggeckos, anolis, water agamas, etc.), aquatic turtles, tortoises, chameleons (panther chameleon, Yemen chameleon, etc.).
