Ultrasun lamps are designed for tropical or desert lizards and turtles. Balanced UVB emission for the growth of solid structures (scales, claws, shells). Prevention of metabolic bone disease. The UVB rays in Ultrasun help reptiles synthesize provitamin D3 (optimal calcium absorption through vitamin D3 production). UVA provides physiological well-being to animals by reducing stress. Ultrasun can be placed on top of the mesh. Simplified installation, as the lamp is self-ballasted: screws into a standard E27 ceramic socket (no separate ballast needed).
