The Zilla Desert UVB Canopy Bulb is a compact coil fluorescent bulb designed to emit small amounts of UVB and UVA wavelengths for reptiles with very low UVB requirements.
Due to experts reporting the UVB output of Zilla Canopy Series Fluorescent UVB/UVA 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.
