Choosing the right UVB UVA bulb can be fun and easy. You’ll find the perfect one for your pet with this guide. Here’s what to look for:
-
Reptile Type: Different reptiles need different UVB strengths. Desert pets like bearded dragons need strong UVB, while forest pets like geckos need less.
-
Bulb Strength: Check the UVB output, shown as a percentage (like 5.0 or 10.0). Higher numbers mean stronger light.
-
