I'm doing a small tenant fit up. In addition to the 40 recessed lights I've already installed in this space, I have a few pendant lights to mount. The issue I'm having is that the ceiling is a 4'by 4' acoustical ceiling tile. I've seen other jobs where these tiles were used however all the lights I saw installed were half a@@ED. I can't seem to come up with a U.L. listed box support, i.e. caddy 512, or the like that will span a 4 foot tile.There is about 5' between the ceiling grid and the fire rated sheetrock/and joists above. I already have Jack chain installed. Was hoping to avoid any monsterous contraptions. Any ideas?? Part numbers would be awesome..
