What is a 365 black light
365nm UV light (also referred to as "long wave UV light", "black light") is a type of near-ultraviolet light that is invisible to the naked eye. It is often used in special lighting applications and is particularly well-suited for fluorescence and bacterial detection.
Is a black light just a purple light
If you turn on a black light bulb in a dark room, what you can see from the bulb is a purplish glow. What you cannot see is the ultraviolet light that the bulb is also producing. Our eyes can see visible light in a spectrum ranging from red through orange, yellow, green, blue and violet.

Can LED lights be used as a black light
LED's can be designed to produce light of any wavelength. Most black light LED sources are in the 385-400nm range, though a little lower is considered the sweet spot for creating the optimal black light effect. A fixture or bulb peaking at around 365nm will cover the entire black light spectrum.
Is 365 nm UV harmful
Most of the risks associated with excessive exposure to sunlight (sunburn, eye irritation and cancers) are a result of UV-B wavelengths. Because UV flashlights emitting at wavelengths 365 nm or higher are emitting in the UV-A range, they can be thought of as being less harmful than the UV-B wavelengths.
What is 395nm UV light used for
The FoxFury HammerHead 395nm UV Forensic Light System is used by field crime scene search, lab and medicolegal (including SANE, coroners and medical examiners) personnel to look for serological / body fluids (including urine and semen), accelerants (oil, gas, turpentine), bite marks, bruising and trace evidence (hairs …
Is black light just darkness

Is a UV light just a purple light
Purple and violet light have shorter wavelengths than other colors of light, and ultraviolet has even shorter waves than violet does; so ultraviolet is sort of "purpler-than-purple" light or "beyond violet" light. Ultraviolet radiation lies between visible light and X-rays along the electromagnetic spectrum.
Can I turn my phone into a blacklight

Is 405nm UV safe
405nm visible light is not as quick-killing as harmful UV light; it re- quires a longer exposure time to accomplish the task. With that said, the 405nm wavelength does not affect the heme porphyrins that exist within humans, and secondly do not cause any cellular damage.
Can black exist without light
As any rainbow will demonstrate, black isn't on the visible spectrum of color. All other colors are reflections of light, except black. Black is the absence of light. Unlike white and other hues, pure black can exist in nature without any light at all.
