Popularly, UV light is what is referred to as “black light.” Technically, any light just outside our eyes’ perception is called black light.
So, near UV AND near IR (ultraviolet and infrared) light are considered black light.
The “Black Light” you use for fun posters or to examine currency is a UV-A band light.
Is a blacklight the same as UV light?
Difference Between Black Light & UV Light. Strictly speaking, a black light is a kind of UV light. Black lights emit ultraviolet radiation (UV light). UV is radiation with a wavelength just shorter than that of violet light, which is the shortest wavelength of light in the visible part of the electromagnetic spectrum.
What kind of light is a black light?
Black lights are lamps that emit long-wave ultraviolet light, and thus, not much visible light.
Do all black lights work the same?
There are actually two different types of black light, but they work in basically the same way. The “black” glass tube itself blocks most visible light, so in the end only benign long-wave UV-A light, along with some blue and violet visible light, passes through.
Will a black light cure UV resin?
The “blacklights” you are talking about are a useless wavelength for what is needed to cure the resin. Yes, they will EVENTUALLY cure the repair but so will a fluorescent light in the right amount of time. The LONG WAVE UV lights used for curing w/s/r resins can be harmful!!!
