"My apartment builder fixed this random looking thing on the roof .Not sure what it is and what it does. It was recently fixed and I’m not sure if it is anything significant. Can anyone fill in my curiosity?"
Answer: "It’s a reflector for surveying. Most likely used to determine building movement/settling over time."

#31 UV-C sterilizing lights should be a very pretty light blue. UV-A/B lights are the common dark purple "black lights" for bug zappers and party lights. NOTE: UV-C sterilize by killing cells, thus DO NOT be in the same room with an exposed (lit) UV-C light. If you start to smell BBQ, that's your skin being cooked from across the room. If you look at it, you're burning cataracts on your eyes and damaging your retinas (extended exposure can lead to blindness).

I have one of these! In spite of what I thought when I first saw it at a garage sale it's comfortable beyond belief. I can sit on it for a couple of hours and get up with no trouble at all.
