FC8T9/BLB BLACK LIGHT BLUE FLUORESCENT LIGHT BULB CIRCLINE BLACKLIGHT BULB

Supra Life fluorescent black bulbs last up to 5 times longer than standard black bulbs. The black light is designed with a special filtered glass that absorbs most of the light from the filament to create a bright fluorescent effect when directed at objects and materials. Long life phosphors reduce color shift and provide consistent lumen output levels up to 90% of rated life hours. Black light sources have many uses. They can be used for decorative and artistic lighting effects, for diagnostic and therapeutic uses in medicine, for the eradication of microorganisms, for the observation or detection of substances labeled with other substances that have a fluorescent effect, for the curing of plastic resins and to attract insects. The light blue black bulbs are similar to normal black lights, but with a filter in the glass to filter visible light and provide only UV light output.
