Black light

Black light is a special gas discharge lamp, which emits a wave of 330-400nm UV light, which is insensitive to human light, so this human insensitive UV light is called black light.

Fluorescent lamps generate light by passing a current through a tube filled with an inert gas and a small amount of mercury.

The use of black light traps insects, insecticidal not only high efficiency, and easy to use, no pollution, can save a lot of pesticides If the use of UV metal halide lamp as a black light source, due to the UV radiation energy, power can be made very high, then A light can manage thousands of acres of land.
