On your canopy, you may want to consider a way to better ventilate the side where the air exits the fixture. ATI fixtures are great because they have active cooling. The air is sucked in through the top and exits the fixture on the side (For the dimmable, I'm pretty sure it's opposite side of the cord). If the fixture isn't properly ventilated, you'll lose performance and have premature failure of the fixture. From what I can tell by your pictures, the fixture might have a hard time exhausting the hot air from the fixture.
