What is the difference between a black light and an ultraviolet light?
Similarly, you may ask, is a UV light and a blacklight the same thing?
A blacklight (or often black light), also referred to as a UV-A light, Wood's lamp, or ultraviolet light, is a lamp that emits long-wave (UV-A) ultraviolet light and very little visible light. Blacklight lamps which have this filter have a lighting industry designation that includes the letters "BLB".
Also, what does UV black light detect? UV light is used to detect the presence of trace evidence in forensic investigations. Blood, urine, semen and saliva can present visible fluorescence. UV or black light reveals changes on the surface of objects as it causes specific fluorescence in materials depending on composition and age.
Keeping this in consideration, are black lights bad for you?
Black Light Safety Most black lights are relatively safe because the UV light they emit is in the longwave UVA range. UVA does not cause sunburn, but it can destroy vitamin A, damage collagen, and promote skin aging. Some black lights emit more light in the UVB range. These lights can cause skin burns.
What is a UV light bulb?
UVC lights are UV germicidal bulbs that emit very short ultraviolet wavelengths from 100 to 280 nanometers that damages the DNA of bacteria, viruses, and other pathogens. These lamps can help eradicate harmful bacteria and are used for a variety of things, namely in the purification of food, water and air.
