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.

* A consistent photoperiod of 14 hours light and 10 hours dark is recommended. An ultraviolet light source should be available within two feet of the lizard (Note: UV light will not penetrate glass).
However, artificial lights cannot replace natural sunlight and even a few minutes of exposure to unfiltered sunlight is beneficial. Slow deliberate lizards may become far more active with a small amount of time in sunlight each day. Although artificial light provides UVB and vitamin D3 may be available as a supplement, there is no substitute for natural sunlight.
