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