A blacklight circular fluorescent is essentially a lamp that emits UV light, which is actually not visible to our eyes as it is outside the range of human vision. While they look just like regular lights, they do just the opposite, which is why a room in which a black light is illuminated still appears dark. But because of this very reason, black lights find huge applications in museums, amusement parks, clubs, Halloween parties and more. But black lights are not all about fun – in fact, they are widely used to check the authenticity of banknotes and antiques, as they can detect fluorescence. But there are more interesting applications too. For instance, a blacklight circular fluorescent is a special UV lamp that can attract insects into traps, and can zap them. These blacklight circular fluorescent lamps are also used to cure resin, plastic, and varnishes in industry. Visit Light Online and explore varieties of black lights.
