It is important to have the proper lighting for your specific reptile. Find out what lighting your reptile needs, then do your best to provide it.
Some important lighting terms:
UVB -This is ultra violet (wavelength) B. This light has a physiological benefit for reptiles. It helps animals synthesize vitamin D3, which allows them to metabolize calcium and phosphorous in their diets, supporting skeletal development, egg production, etc. Animals that bask in their natural habitat need more UVB; such as iguanas, turtles, etc. Animals that live on the forest floor or under rocks need less.
UVA - Ultra-Violet (wavelength) A. This light is more psychological in its benefit. It gives the appearance of natural sunlight, making food and prey items look more realistic. It is also believed to aid breeding, hibernation and generally help to define normal photo-periods.
FULL SPECTRUM - When used in discussions of lighting, it refers to the full visual spectrum, i.e., containing all visible wavelengths. Full-spectrum light reflects all colors of prism refraction: red, orange, yellow, green, blue, lavender, indigo and violet. Full spectrum does not include non-visible light such as ultra-violet.
DIURNAL - Animals that are active in the daylight and rest in darkness. This describes most reptiles kept by hobbyists. Reptiles are ectothermic (cold-blooded), so they need the sunlight to raise their body temperatures.
NOCTURNAL - Animals that are active in darkness and rest during daylight. Amphibians, including many frogs and toads.
