Jeez, every response in here is about it burning your eyes. Thing is, people aren't in every room all the time. Have it set to a sensor, same as the lights, and you can quickly sanitize large spaces that are unoccupied. Elevators, airplanes, etc can be sanitized the second they're empty. My FIL is a retired GE engineer working on this technology.

Sounds dangerous

I have lights go out on me all the time at the office, just sitting mildly still. What happens if someone falls asleep in the room? Or worse a kid? Severe sunburn and possible blindness

Better presence sensors exist, and are only used in such critical situations. These are based on radar and sense the chest movements of people.
