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

Or what if they're black? I've read so many stories about sensors not detecting people simply because they have darker skin.

I dont think the lights would be on the entire time the room was empty...

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