Black Light Bulb (Kallemax)

Black Light Bulb (Kallemax)

A black light is a type of light bulb that emits mostly ultraviolet radiation. Although most bulbs also give off a faint violet glow, the majority of the light is outside the visible range. This energetic radiation excites molecules, often producing fluorescence or phosphorescence. A visible photon is released when a molecule loses the absorbed energy, making the substance appear to glow in the dark.
