The Zilla Tropical 25 T8 UVB Bulb is a T8 linear fluorescent UVB that produces lower amounts of UVB for tropical and forest-dwelling reptiles.
Due to experts reporting the output of Zilla UVB bulbs as "potentially unreliable", we do not recommend using this product without a Solarmeter 6.5 to make sure your reptile is getting the right amount of UVB.
We recommend the Zoo Med T8 ReptiSun 5.0 as an alternative.

4" below lamp — UVI 2 - 8
