Kale, Your guess is as good as mine. I also love the way the far light rests partly ATOP the bus duct (not the HVAC this time :-)). I'll try to get another pic....this was obviously a place rife with incompetent management, and a maintenance department that used dumpsters as their "parts house."

Is that one down by the "familiar" looking sprinkler a 2x4 troffer with no lense? Don't worry... ...I'm sure they'll hang the other side independently of the bus duct as soon as someone throws some jack chain in the trash.

What gave me the willies is that there is no visible means of support for that twin-tube strip light. I'm afraid to open it, and find someone mounted it with self-drilling screws- right where the PoCo feed comes in through the wall!
