Fluker's Sun Glow Coil Bulb 5.0 UV Bulb 20 Watts

Under natural conditions, the sun produces ultraviolet B radiation (UVB). UVB radiation is needed to produce vitamin D. In captivity, reptiles that have poor lighting conditions can develop life threatening diseases. Sun Glow fluorescent bulbs provide essential ultraviolet B radiation for captive reptiles and amphibians. These bulbs actually generate more UVB (> 250 vwatts/cm2 ) than competitor's 5.0 fluorescent tubes (> 250 mwatts/cm2 )! Sun Glow bulbs should be used in combinationwith Fluker's incandescent bulbs which can be used to regulate the environmental temperature.
