Question

If you paint a regular white light ....black will it be a black that they use in clubs?
just want to know if u paint a regular high voltage light black or some other dark color do it become a black that owners use in clubs

Answer

quotBlackquot lights have a special HEATPROOF, NONFLAMMABLE coating that allows only ultraviolet and some visible violet wavelengths of light to pass through Why they look purple... Black paint would allow no light to pass through, or block equal amounts of all wavelengths if the coating was thin... Wouldnt work. quotBlackquot lights run hotter than regular lights of the same wattage because of all the visable light energy reflected back by the dark violet coating and quottrappedquot in the bulb..brbrNote... There is no special filament in an incandescent black light bulb. Its all in the coating. The light from a fluorescent tube has more output in the ultraviolet range, so fluorescent tubes make better black lights.
