Leopard geckos are active mainly around dawn and dusk, but veterinary husbandry guidance indicates that they benefit from low-output UVB lighting.
What strength UVB does a leopard gecko need?
Low-output UVB is appropriate for this species; the Royal Veterinary College gives approximately 6% as an example. Exact lamp placement depends on the fixture, enclosure, mesh and manufacturer's instructions.
How long should UVB stay on?
A roughly 12-hour daytime light cycle is commonly used. Replace or test UVB lamps according to the manufacturer's guidance because visible light does not tell you how much useful UVB the lamp is still producing.
