The thing to remember is that each reptile comes with an perfect choice for UV lighting. You need to make sure that they're getting enough, but you don’t want to overdo it and get the maximum UV output available. Here are tips on lighting needs for some of the most popular
Reptile Daylight lamp:
Bearded dragon--needs just two different light sources, you to give heat and UVA light and another to provide UVB light. Bearded dragons require a number of the highest quantities of UVB of reptile pets. Your beardy will perform best using a mercury vapor bulb like
full spectrum daylight bulb or a fluorescent tube. Compact fluorescents don't give off enough UVB for bearded dragons.
Veiled chameleon--additionally needs different heat/UVA and UVB lights. Unlike chameleon species that reside on the rainforest floor, the veiled chameleon needs moderately high levels of UVB exposure, and compact fluorescents aren't sufficient.
Green iguana--requires separate bulbs for both heat/UVA and UVB. Because green iguanas are larger reptiles that require big timers, you will probably need two UVB bulbs which cover a large area, such as
Fluorescent Tube Lamp.
Corn snakes--only require one light source that offers warmth and UVA. Most snakes do not need different UVB lighting.
Ball python--necessitates only heat/UVA lighting.
