The new AvianSun™ 5.0 UVB Compact Fluorescent Bulb from Zoo Med is the first true full spectrum bulb specifically for birds, that provides visible light, UVA, and UVB. This bulb is designed for use with Zoo Med's new AvianSun™ Deluxe Floor-Lamp. This unique lighting arrangement will provide birds with safe levels of beneficial UVB and UVA for physical and psychological health. 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! Give your birds Zoo Med's AvianSun lighting and bring the sun indoors!
