Zilla 11410 Desert 50 UVB Fluorescent Bulb, 20-Watt Coil
When it comes to the bone health of a desert reptile, the extra daily dose of UVB light provided by a Desert 50 bulb (50 microwatts per second/cm2) is as essential as proper food and water for long term strength. The Desert 50 family of bulbs also provide needed UVA light, plus visible-spectrum illumination that makes skin coloration more vivid and viewable. Get all this in a family of high-efficiency bulbs designed to fit most major fluorescent fixture types. Desert 50 bulbs are designed for 3500 hours or twelve full months of average use.
