The Zilla Tropical 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.
The UVB output of Zilla Canopy Series Fluorescent UVB/UVA Bulbs is too low to be significantly beneficial to reptiles. If you are looking for a tropical compact UVB bulb for your reptile, we recommend the Zoo Med ReptiSun 5.0 Compact Fluorescent instead.
