UV light is Ultra Violet light which when switched on, glows neon colours up in the dark. For UV lights to work successfully, glowing face-paint, clothing, shoelaces etc. up, then the room needs to be dark, otherwise light will dilute the UV rays.
Lighting effects which are not specifically UV do not glow you up in the dark. They create effects on walls and ceilings, depending on the type of light. So, UV light glows you up in the dark, while all other lights create effects around the room.
