Cow, these fixtures are made by Cooper
who own about two-three dozen other lighting and electrical brands (Including Halo a well made fixture for the price, and easy install) - They knew when the designed it. (If these had Halo's hanger bars, and Iris's J-box - I would promote them myself.)It would be like Ford saying they didn't know what the designers at SAAB, Volvo, Ferrari, Jaguar, Mazda, Austin Martin, and Lincoln were doing.... I'm sure they know very well that Mercury's have a few design flaws too - but don't care. Cooper, I am sure does not care what we think about installing them, so long as they can sell them to designers and architechs for looks alone.
BTW I did come up with an interesting way of hanging them. By screwing a piece of channel to the cieling so the edge was the same distance of CL to edge of the fixture opening. That way you could balance the fixture up there butted against the channel, and install the extra support needed to stabilize it. Tek screw through each hanger bar it came with and one or two more to lock it so it doesn't float around on them flimsy things. And make sure your in-outs are twisted and have firm connection - believe me, you never want to go into these after rock. Especially the IC version. You'll need mirrors, lights, picks and hooks to do it. Like some sort of keyhole surgeon.
