Saw at the Loma Linda ReStore, looked used, didn't get as I didn't really need or want, rather bulky. You can see how deep it is compared to a regular fluorescent troffer. I w was priced at $10.
Interesting... If I had bought it I'd probably paint it a dark color and convert it to incandescent or fluorescent and make it into a pool table light lol.
I'm actually thinking that it's an experimental fixture. It would definitely need strong hanger wires as it would probably fall through a T-bar ceiling..
Something like that would be kinda cool to have! But I wouldn't have bought it either simply because its so big (and I would truly have no use for it)
