The Zilla Desert 50 T8 UVB Bulb is a T8 linear fluorescent UVB that produces higher amounts of UVB for desert 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 10.0 as an alternative.
