Disinfection Efficacy
Both UVC LED and UVC Lamp have been proved to be effective for diminish bacteria and viruses including the pathogen of COVID-19, SARS-CoV-2, with suitable UV intensity and expose time.
UV mercury lamps with better optical power and lower price have been the major source for most UVC disinfecting products. Signify, for example, increased capacity for its UV mercury lamp production for meeting the rising demands for disinfection.
But LED makers have also improved their UV technology and achieved breakthroughs recently years. Manufacturers such as AquiSense, Asahi Kase, Crystal IS, Dowa, High Power Lighting, Seoul Viosys, Stanley, Violumas and more have produced UVC LEDs with advanced efficiency and higher power output.

Safety
UVC light not only kills virus, it can also cause damages to human skin and eye. Therefore, when using disinfecting products based on either mercury lamps or LEDs, it is important to avoid direct exposure of the light. The Global Lighting Association has provided guidelines focusing on UVC disinfection products for manufacturers and users to prevent potential hazard of such applications.
It is also worth noticing that the safety guidelines or standards available at the moment mostly base on mercury lamps. Safety standards of UVC LEDs have yet be defined with effective verification as they do not take big market share. But since UVC LEDs are easily adopted with portable products like UVC light wands, which have been popular disinfecting products for the consumer market, people need to pay extra attention when using such devices and avoid direct exposure to the skin and eyes.
