I've got recessed LED fixtures in the dining room. (Juno IC22 housings.) They were installed after the old plaster ceiling had been removed, so they're fastened to the joists with telescoping bar hangers.
Now that I'm installing a plank ceiling, I've found that in order to account for how far out of level the joists are, the finished height of the planks in the area of the fixtures is such that the adjustability of the fixture trim won't quite go low enough.
Here is a photo of one. It only needs to go about 1/2" lower. (That's the approaching planks coming in from the left.)
If the torsion spring clips can be replaced with some that are slightly longer, that would do it. The ones that came with it are four inches on either end of the spring.
I'm looking for some that are at least 4-1/2" on each leg of the spring. The only ones I've found available online are either labelled as 4" or don't have any dimensions specified.
Do these clips come in different sizes? Alternatively, is there another way to get the trim of the fixture about 1/2" lower.
