REPTILAMP UVA UVB Reptile Light Bulb - 26W CFL Replacement LED UV Lamp for Terrariums & Reptile Habitats - Ideal for Lizards, Turtles & Snakes

Reptiles and amphibians need both UVB and UVA light to live healthy lifestyles. These are both types of ultraviolet (and UV) light. Each type of light has a different role to play in keeping your pet happy and healthy. The UV spectrum is broken up into three parts: UVA, UVB and UVC. All three of these types of light are found in natural sunlight. UVA light helps regulate behaviors such as feeding, diurnal movement, mating and similar activities. UVB light allows the synthesis of vitamin D3, which helps to absorb calcium. UVC light is not required for reptiles. It's important to note that at high levels of exposure this light can be harmful to most animals.
