As we know Uvblight is produced by sun
Ultravioletlight is an impulse, which has special wavelength. Its quite shorter, thanvisible light, however if compare with X-rays, uv wavelength is longer and hasthe range about 40-400 nm. For human eye such light is invisible, but differentinsects and birds can see it. As we know Uvblight is produced by sun, but can be obtained artificial way, for exampletanning beds and UV lamps. Such lamps have a spectrum of light with the lengthof wave 290 to 320nm. Scientists call it biological spectrum, because its notharmful for human, sure if exposure time isnt much, because there alwaysexists chance to get sunburn. Biological features of ultraviolet light affectsour body on molecular level, and can cause severe damage, thats why one shouldtreat carefully.
Ultravioletlamps use artificial uv light and can be divided into two main types:
Broadbandlamp and narrowband.
The firstone works with the wavelength spectrum of 290-320 nm, reaching its top on306nm. It effects on our skin quite strong in medical sense if compare withnarrowband lamps, however both type are proven ceiling panel light not to be harmful in medicaltreatment of skin disorders.
Uvb lamp with narrow spectrum has the length of wave311-313nm, with the top on 312nm. Here you can see, that such lamp uses narrowspectrum even from its name. If we turnto the treating skin disease we can see by the results of different researches,that exactly narrowband lamps are more effective than broadband. Such lamp issafe and due to its narrow spectrum helps to treat only affected areas nottouching healthy skin. There exist gossips, that broadband lamp can cause skincancer, but not narrowband.
UVB light bulbs
Ultravioletlamps or bulbs are very effective in treatment skin disease such eczema,psoriasis and many other. These bulbs can be of different sizes. It can beportative for home therapy and big cabins for clinical treatment. Sure itdepends on affected areas of skin and what treatment is prescribed.
