Full Spectrum Compact Fluorescent Bulb for Bird Cage

All Light bulbs contain some UVA...not all contain proper levels as well as UVB levels.

UVB enables birds to synthesize vitamin D3 for proper calcium metabolism which is necessary for normal growth, maintenance of strong bones, and egg production. UVA is visible to birds, enabling them to recognize mates, locate food, and identify different species. Without UVA, birds are essentially colorblind!
