The functionality of reptiles depends on light thus, providing adequate light to reptiles is imperative if you have them as pets. However, the daylight bulbs required for different reptiles vary based on their natural habitat and unique needs. The kind of lightning usually used is ultraviolet light, and they come in different types such as UVA and UVB. While the UVC spectrum also exists, it is discouraged in production because of its harmful effects.
