Energy Focus’ AbUV circadian lighting and UV-C air disinfection troffer provides continuous disinfection designed for more than 99.9 percent effectiveness against airborne pathogens. A built-in fan draws, disinfects, and circulates air at approximately two air changes per hour in a 200-square-foot space. The disinfection troffer uses a lighting control platform that provides flicker-free, dimming, and color-tunable LED lighting.
