Up to 30% total energy output in the UVA wavelengths which help to increase appetite, activity, and induce reproductive behavior in captive lizards, turtles, and tortoises.
Up to 5% of the total energy output is in the UVB wavelengths which help to prevent or reverse metabolic bone disease. UVB lighting is safer than adding powdered D3 supplements as it allows your animals a chance to regulate their own vitamin D levels by endogenous synthesis as they would in nature. Unlike most other reptile bulbs, the UVB in the Repti Sun 5.0 UVB will penetrate up to 12" from the bulb's surface. In most other reptile bulbs, the UVB completely dissipates at three to four inches from the bulb's surface.

The UVA and UVB wavelengths simulate sunlight for turtle or tortoise basking. This also helps to strengthen the turtle's shell thus aiding in preventing "soft shell" problems in captive turtles and tortoises.

Used and recommended by zoos, veterinarians, and top reptile professionals.
