Why UVB Light Matters for Reptiles
Reptiles, like lizards and turtles, depend on ultraviolet B (UVB) radiation to synthesize vitamin D3. This vitamin is essential for calcium absorption, which in turn affects bone development, immune function, and metabolic health. Without adequate UVB exposure, reptiles can suffer from metabolic bone disease (MBD), lethargy, poor appetite, and even shortened lifespans.
What Is the UVB Index?
The UVB index is a measure of how much UVB radiation a lamp emits. CTT classifies its reptile lights based on UVB output:
UVB 10.0 – High Output: For desert-dwelling reptiles requiring intense UVB.
UVB 5.0 – Moderate Output: Suited for forest and tropical reptiles.
UVB 2.0 – Low Output: Ideal for rainforest reptiles and amphibians in shaded habitats.
