The cleanest unit with the lowest back panel profile I've seen. With this light, installation was the easiest I have ever experienced. For the 6" LED I used a 4-1/4" hole saw for the ceiling box and it looks very clean with no ceiling gap. is 4 inches in diameter and works well. [Update] I bought the Ostwin model for comparison. Ostwing has a scalloped edge versus Jullison's tapered edge and I will be buying both. Ostwing supplies both long and short machine screws and that helps. only with standard screws. I often need a longer one to get to the ceiling box hence 5 stars dropped to 4 stars.
