Can Germicidal Lighting Combat COVID-19?

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 more complicated than simply turning on a UV light.

Germicidal Ultraviolet Light - Technology Newsletter

Suddenly there is a growing interest in germicidal lighting. A quick look online or at manufacturers’ literature and websites shows a proliferation of germicidal lighting equipment from permanently installed luminaires to portables, including light wands and screw-in germicidal bulbs, all designed to decontaminate objects, materials or surfaces.

As an industry that is being significantly impacted from the ramifications of COVID-19, it is important to gauge the opportunities in front of us and how we can differentiate our businesses moving forward. Our top priority is to do everything we can to help our members and the lighting industry remain healthy, both in body and business.
 
And, lastly, some cautions:
 
  • Insist upon and read carefully all GUV product safety and caution notices. If none are provided, ask the manufacturer. If you feel the information provided is incomplete or hard to understand, consider not using the product.
 
  • Germicidal lighting works only via line-of-sight. Reflected light does not kill germs because most reflecting surfaces in homes absorb the critical UV-C wavelengths.
 
  • Exposure matters. Exposure = Intensity x Time. Like sunburn, damage to skin and eyes results from being exposed for too long to the light source. GUV exposures, however, are likely to be measured in seconds and minutes, not hours.
 
GUV is a good way to help control the spread of the COVID-19 virus. Learn the facts to apply it effectively and safely. Be safe and well.
 
Sincerely,
