Ultraviolet light is an impulse, which has special wavelength. It’s quite shorter, than visible light, however if compare with X-rays, uv wavelength is longer and has the range about 40-400 nm. For human eye such light is invisible, but different insects and birds can see it. As we know Uvb light is produced by sun, but can be obtained artificial way, for example tanning beds and UV lamps. Such lamps have a spectrum of light with the length of wave 290 to 320nm. Scientists call it biological spectrum, because it’s not harmful for human, sure if exposure time isn’t much, because there always exists chance to get sunburn. Biological features of ultraviolet light affects our body on molecular level, and can cause severe damage, that’s why one should treat carefully.

Uvb lamp with narrow spectrum has the length of wave 311-313nm, with the top on 312nm. Here you can see, that such lamp uses narrow spectrum even from its name.  If we turn to the treating skin disease we can see by the results of different researches, that exactly narrowband lamps are more effective than broadband. Such lamp is safe and due to its narrow spectrum helps to treat only affected areas not touching healthy skin. There exist gossips, that broadband lamp can cause skin cancer, but not narrowband.
