Ultraviolet Light Bulbs
Ultraviolet light (UV) is invisible to the human eye. It is part of the electromagnetic spectrum that lies beyond the purple range of the visible spectrum. The ultraviolet spectrum has wavelengths between 100 and 400 nanometers (nm). The UV spectrum is further divided into wavelength ranges named UVA (blacklight), UVB (phototherapy), and UVC (germicidal).
We carry ultraviolet light bulbs using all of these wavelengths for a variety of stage/studio, special effects, phototherapy, and air/water purification equipment. If you can not find the ultraviolet bulb you need, call 800.784.1998 to speak with a lighting specialist. In most cases, we can help you locate the UV bulb you are looking for.
About UV Bulbs & Fixtures
All of the bulbs and fixtures in this category emit light in the ultraviolet part of the spectrum. However, not all UV bulbs or fixtures are interchangeable. There are a large number of applications utilizing UV light.
The UV-A part of the ultraviolet spectrum is used in a wide variety of applications. Commonly referred to as blacklights, these UV bulbs are much more than a novelty. Although they are used in many blacklight fixtures in stage/studio applications, blacklights can be used for fraud detection of currency, validation of identification, and even identifying organic waste to track the path of bedbugs.
UV-A light provides very little disinfection power, although it can have some germicidal effectiveness over very long periods of time. It is generally not dangerous to humans, except in high dosage amounts.
Specialty UV-B bulbs are used in medical settings for treatment of jaundice, skin disorders, and other conditions. It can also be used for some germicidal applications, although it does not have nearly the effective power of UV-C lights.
UV-C light can be extremely harmful to human and animal skin and eyes, and is used for disinfection of air and surfaces, as well as water purification. Most UV-C light from the sun is filtered out before it even hits the earth.
UV-C germicidal bulbs and fixtures are most often used in medical settings to sanitize surfaces and clean rooms. Municipalities have long used UV-C for water purification. And with the increased awareness of the danger of airborne pathogens, the demand for UV-C for air purification has skyrocketed.
