Yeah wee have some neat arms too from the 60s. And even fewer from before then from the remote ballast MV and incandescent days.
BTW, I relamped the three bathrooms with the short ceilings! I used my short 6" folding step stool. Both 1st floor bathrooms and one 3rd floor bathroom were relamped. The other 3rd floor bathroom and both 2nd floor bathrooms have the tall ceiling. The only time anyone came into the bathrooms while I was relamping was the 3rd floor bathroom; a teacher came in while I was fixing the light by the door and he came close to peeing himself (or crapping himself, if that's what he was going in there to do lol). He just asked if it was alright for him to go into the bathroom (seeing that I was working on the lights). I said "yep, I'm just finishing up. Finally got some light in here!" And it was all good. His look changed to confused when he saw the backpack though, since he then realized I was a student and not a maintenance hand. He didn't say anything though.
So... Seeing that those bathrooms were a success, I will be back with a taller ~24" stepladder to finish what I started in the bathrooms with the taller ceilings. The extra light actually does make a bit of a difference. I'll grab pics and post them to LG in a couple weeks.
