American Lighting Association (ALA) has recently shared a wealth of information on the topic of germicidal lighting which can be very useful during this time of pandemic with the novel coronavirus COVID-19. We are sharing some of this information they’ve sent, but also check the link at the bottom for more information and resources compiled to better inform yourself and your customers.
The use of germicidal ultraviolet technology can be effective with proper safety precautions
The use of germicidal lighting as a potential way to combat germs and viruses, including COVID-19, is receiving a lot of interest and publicity lately. Germicidal ultraviolet “light” or GUV refers to the technology of germicidal lighting, which utilizes ultraviolet-emitting sources. While GUV is a technology with great opportunity, it is also more complicated than simply turning on a UV light.
It is imperative to be cognizant of the safety and efficacy issues, and to be educated about the capabilities of the different types of UV light.
- UV-A – traditional blacklight used in insect traps and theatrical settings, abundant in natural sunlight and daylight
- UV-B – also present in sunlight, excessive exposure causes sunburn and repeated exposures over time can result in skin cancer; so-called tanning lamps emit UV-B
- UV-C – germicidal lighting, requires strict precautions, damaging to eyes and skin, not present in sunlight
