UVB wavelengths along with proper temperature (usually additional heat), are responsible for vitamin D3 production in reptiles. However, only some UVB wavelengths (from 290-315 nm) help synthesize Vitamin D3. The Reptisun® UVB/LED bulb emits UVB wavelengths from 295 nm to 320 nm.

UVA is part of reptile vision, so without it they’re colorblind! A portion of UVA wavelengths (from 320nm-335nm) also help regulate Vitamin D3 production and let reptile’s body’s know when they’ve created enough. The Reptisun® UVB/LED bulb emits UVA wavelengths from 320nm-335nm and from 355nm-395nm.

Visible light is critical to reptiles as it is for humans. The amount of visible light a bulb emits is measured on a temperature scale corresponding to the warmth of the light relative to color. A bulb emitting light between 5,000 and 7,000 Kelvin most closely resembles the sun. The Reptisun® UVB/LED has a color temperature of 6,500 Kelvin.
