Are black LED lights possible?

Are black LED lights possible?

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. This is due to the phosphors within an LED lamp that convert the Ultraviolet light to white light.

Does Colour black exist?

As any rainbow will demonstrate, black isn’t on the visible spectrum of colour. Black is the absence of light. Unlike white and other hues, pure black can exist in nature without any light at all. Some consider white to be a colour, because white light comprises all hues on the visible light spectrum.

Why is there no black colored light?
