The Avian Sun has been completely redesigned. Now with a NEW adjustable gooseneck, the Avian Sun Deluxe Floor Lamp from Zoo Med allows bird keepers to provide their birds with true full spectrum light, including UVB and UVA, just like they get in their natural environment. This floor lamp is designed for and includes the Zoo Med Avian Sun 5.0 UVB Compact Fluorescent 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.
