Black lights in particular have a wavelength between 315-400nm. There are a variety of ways to create this effect including using special glass or actually emitting these wave lengths from an LED. Ultraviolet is mostly invisible to the naked eye because the human eye can not see below 400nm. Ultraviolet light has many more purposes other than creating cool colors on your favorite band's posters. These range from forensic investigations to sports fishing. Bodily fluids such as saliva, urine and semen fluoresce under an ultraviolet light. There are several professions that use ultraviolet flashlights to help them do their job based on this fact. Hotel staffs have started using ultraviolet flashlights to ensure that they have properly cleaned a room. Each attendant checks each section of the room and inspects it to ensure that the next guest has a clean environment to rest. Any time the light causes something to glow green they know they have missed a spot and clean it up immediately. Another profession that uses ultraviolet flashlights day-to-day to detect saliva, urine and semen are forensic detectives. The ultraviolet light allows forensic detectives to see where a mess has been cleaned up trying to hide evidence at a crime scene. While the mess might seem clean to the naked eye, these fluids leave a residue that is not easily removed. Pepper spray companies have also started adding extra chemicals that will fluoresce under ultraviolet light. Again, these chemicals are not easily removed, so if you are in a scuffle and run away, detectives can use an ultraviolet light to prove that you were at the scene. If you are naughty your local CSI will be able to figure it out. Sometimes you need to be your own CSI unit. You know your pet has urinated in your house but you can't seem to figure out where. An ultraviolet light is great for helping pet owners track down where their animals have been urinating so that it can be cleaned up. Nightclubs and other establishments which take cash also require ultraviolet lights to ensure the currency they are receiving is legitimate. United States currency uses strips of precisely placed strips of plastic in their bills. These plastic strips will fluoresce under a black light. Each bill fluoresces a different color. This means counterfeiters must get the location and color of the strip correct to be able to pass off fake bills. The U.S. government also use paper that does not fluoresce, so if your bill lights up in the white areas, you have found a counterfeit bill. Even credit card companies have started using ultraviolet lights to determine if the cards are legitimate. They load the cards with holograms that only show up under ultraviolet light next to the hologram that is visible in visible light. Many states are using anti-counterfeiting systems to ensure their state driver's licenses are not fake. This discourages teens from using fake IDs to gain access to environments where they are not allowed. But forensics and documents are not the only use for ultraviolet lights. Many animals see in the ultraviolet spectrum. Fish are especially attracted to ultraviolet light. Sports fish like bass and trout are especially attracted to ultraviolet light because their prey fluoresce when exposed ultraviolet light. Tackle companies have started offering lures with fluorescent bodies in an effort to attract more fish to the bait. Field and Stream found that this is a legitimate way to catch more fish, especially as the sun goes down. Fish aren't the only animals that fluoresce under ultraviolet light. Scorpions’ exoskeletons have a protein called beta-carboline which causes them to fluoresce under ultraviolet light. Not only are scorpions scary looking, but they glow in the dark too. We sell many UV lights to people that live in Arizona where scorpions are considered pests. The best way to find scorpions is using a UV light.
