Black lights look just like normal fluorescent lamps but they do something completely different. Ours is an 18 inch fixture that is perfect for exploring natural glow in the dark objects in your home, or with specific glow in the dark decorations like our Level Ring or specially formulated paints and powders
A tube black light is a basically a fluorescent lamp with a different sort of phosphor coating. This coating absorbs harmful shortwave UV-B (280-320 nanometers) and UV-C light (below 280 nanometers) and emits safe UV-A light (320-400 nanometers). The "black" glass tube itself blocks most visible light, so in the end only benign long-wave UV-A light and some blue and violet visible light pass through.
Interesting Fact: If you walked around all night with a portable black light, you would discover that there are phosphors all over the place. There are lots of natural phosphors in your teeth and fingernails, among other things. If you have a dog in your house, the black light will highlight any "accidents." The first thing many people notice is that some of their clothing glows. This is because most laundry detergents contain phosphors to make whites appear brighter in sunlight. Sunlight contains UV light that makes the whites glow "brighter than white."
Don't have room for the light fixture? Consider our 75 W black light bulb instead. You can place it like an ordinary light bulb.
