Avian Adjustable Floor Lamp for Bird Provides birds with true full spectrum light. Includes UVB and UVA to radiate their natural environment. 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 calcium metabolism which is necessary for normal growth, strong bones and egg production. UVA is visible to birds, enabling them to recognize mates, locate food and identify different species.
