Why aren't black lights black?
Black as a color would absorb all visible frequencies of light. A "black light" is not actually black, but rather emits most of its light in the ultraviolet frequencies. This light is invisible to our eyes except that it interacts with certain materials that fluoresce (glow in the dark) when they absorb UV light. These lights are also used for indoor plants that need UV light to grow.

Do black lights use more electricity than regular bulbs?
Black lights typically use the same amount of electricity as regular bulbs of the same wattage. The difference is in the type of light they emit: black lights emit ultraviolet (UV) light, which is not visible to the human eye but can make certain materials glow.
Why cant you produce black light?
Black light is produced using ultraviolet (UV) lights. These lights emit UV radiation, which causes certain materials to glow or fluoresce in a way that appears to be black light. Other colors of light don't have the same effect on these materials, which is why they cannot produce black light.
What substances are in black lights?
Black lights primarily emit ultraviolet (UV) light, typically in the UV-A range, which is around 320 to 400 nanometers. The light is produced using a phosphor coating on a fluorescent tube or by LEDs designed to emit UV light. Common phosphor materials in black lights include compounds like barium, strontium, and zinc. Additionally, the glass of the tube is often treated to filter out visible light, allowing primarily UV light to escape.
