The full spectrum of natural light is important for the health of lizards. Ultraviolet wavelengths are specifically important for vitamin D and calcium metabolism. There are two bands of UV: UVA and UVB. UVA (320-400nm) produces beneficial behavioural and psychological effects but does not activate vitamin D precursors in the skin. UVB (290-320nm) is necessary for vitamin D synthesis.

However, artificial lights cannot replace natural sunlight and even a few minutes of exposure to unfiltered sunlight is beneficial.
