While low, there is still some power of a conventional black light in the UVB range.
UVA is the safest of the three spectra of UV light, although high exposure to UVA has been linked to the development of skin cancer in humans.
The relatively low energy of UVA light does not cause sunburn.
Do black lights give off radiation?
There is no evidence to suggest that insect traps using ultraviolet black light increase your risk of developing skin cancer, as the amount of ultraviolet radiation they emit is very low. Black lights emit a type of ultraviolet radiation called UVA, which is invisible to the human eye.
Are black lights Ultraviolet?
A black light looks dark purple, but most of the light it emits is in the ultraviolet (UV) range of the spectrum, which is invisible to the human eye. Under a UV light, white clothes, our UV poster [link], glow in the dark and many fluorescent coloured items emit a bright glow.
What kind of cancer does UV rays cause?
Exposure to UV radiation is the main factor that causes skin cells to become cancer cells. Almost all skin cancers (approximately 99% of non-melanoma skin cancers and 95% of melanoma) are caused by too much UV radiation from the sun or other sources such as solaria (solariums, sunbeds, and sun lamps).
Is UV bulbs dangerous?
Exposure to ultraviolet (UV) radiation is a risk factor for most skin cancers, according to the American Cancer Society. Natural sunlight and UV lamps used for tanning give off the harmful rays, as do the small lamps used to speed drying in nail salons. UV-A is one of three types of UV ray.
