First of all, Crested Geckos don’t absolutely need UVB light to live, but some studies suggest it can help them stay healthy and act more like they would in the wild.
That’s why many people who own reptiles use it.
However, the best UVB bulb for a crested gecko is a low-level UVB bulb made for shade-dwelling species, ideally mounted above the screen with no glass or plastic underneath.
Some great options I suggest are:
- Zoo Med 5.0 T8 linear UVB.
- Arcadia 6% UVB.
- And Arcadia ShadeDweller bulbs.
These are the ones I really recommend!
Just make sure whatever you choose gives off 2.0% to 5.0% of UVB light, but not more than 7.0% to 10.0%.
Hope it makes sense!
