A. For open top enclosures or when there is no material between the bulb and the animal:

1 Use a T8 2–6% bulb at distances up to 15 inches between the bulb and the animal; for distances over 15 inches, a T8 10–12% or T5 6% bulb may be required.

2 Provide a UVB and heat gradient so animals are not constantly exposed to UVB light.

3 Turn UVB light on for 2–4 hours daily to every other day, especially for cryptic or fossorial species that are naturally exposed to low levels of UVB.

For enclosures with a screen/mesh between the bulb and the animal:

1 Use a T8 6–12% bulb at distances up to 15 inches between the bulb and the animal; for distances over 15 inches, a T8 12% or T5 6% bulb may be required.

2 Provide a UVB and heat gradient so animals are not constantly exposed to UVB light.

3 Turn UVB light on for 2–4 hours daily to every other day, especially for cryptic or fossorial species that are naturally exposed to low levels of UVB.

Note: depending on the type of mesh, there may be a 30–50% reduction in UVB, which must be taken into consideration when selecting the bulb. The use of a UVB radiometer is more critical when the bulb is placed above a mesh in order to determine the actual UVB exposure.
