What Is Black Light Used For?
Black light bulbs have been around for decades. Once considered a psychedelic gimmick, they have become a mainstay in society. This unique part of the light spectrum, known as ultraviolet light, is not noticeable under normal visible lighting conditions. Some objects take on a bright or glowing hue when exposed to black lights.
There are many uses for these bulbs. Whether incandescent or fluorescent light bulbs, they have scientific, practical and recreational uses. They come in many shapes and sizes and are available in stores as well as on-line.
Forensics
With the popularity of television shows focusing on forensic crime labs on the rise, black light bulbs have come to the forefront. The CSI series regularly features crime solving in the lab with help from other gadgets and instruments. More than one case has been cracked by blood stains or bodily fluid showing up on a wall or under a microscope featuring these special lights.
Chemical Studies
Some objects require a chemical reaction to make them illuminate. One example is white paper. When it is created, chemicals are sometimes added to make it appear brighter and cleaner in regular lighting. This additive started about 50 years ago. As a result, most plain white paper and some white cotton T-shirts glow in the dark when exposed to the ultraviolet end of the spectrum.
Aquariums And Other Natural Effects
Many everyday materials glow under this type of lighting without adding anything. Legos, petroleum jelly and club soda all fit in this category. Some vegetables, like spinach or chard, may emit color under this type of light.
Black lights in aquariums or terrariums has increased in popularity for school children, especially as science projects. Some creatures glow, while others just have a luminescent habitat at the flick of a switch.
Clubs And Bars
Many nightclubs have jumped on the black light bandwagon. Using this type of lighting on dance floors or over bars creates a mystical and festive atmosphere. Patrons are often encouraged to wear white clothing. The bar industry has also taken to using plastic products that glow, adding to the aura as servers walk around with glowing trays.
Many of the specialty drinks served feature alcoholic beverages that glow under these conditions. Blue Curacao, food coloring and tonic water are three elements that illuminate beverages under black lights. Absinthe, some sports drinks and certain flavors of Jell-o have the same effect.
Safety
One of the most popular industrial uses for black light is in the safety arena. Fluorescent and phosphorescent materials will illuminate to reveal fuel tank leaks, measurement marks and invisible chalkboard notations, allowing things to be seen in special conditions that do not need to be seen by the naked eye in normal lighting. Military operations and spacecraft excursions use these special features as well.
