No offense, Mike, I know you're an over the top kind of guy, but vapor tight fixtures in an attic?? In the garage I guess I could see them. They are pretty.
Honestly, for half the money and twice the light, I would have installed 8' tandem strip lights with four 4' T8 LED lamps. 4' 2 lamp fixtures would have been fine for the attic. In the garage, I would have installed the 8' strips and mounted them end to end so I had a continuous source or row of light with no dark spots in between the fixtures.
It wouldn't be as pretty but double your light for half or more the cost.
