Very nice lights. Note that the portion of the slab is less than 4 inches - closer to 3 inches. If you're trying to match these gimbals with the Lithonia WF series, keep that in mind. Installation is easy in theory, but gets a lot more annoying than necessary due to Halex-style cable clamps being too tight. Maybe it's ok for 14 AWG wire, but I had 12 AWG wire in this circuit and it's very difficult to run 12 AWG wire through these connectors. The wire can rub against the terminals where it exits the junction box. I don't know why they didn't put the clamps 90 degrees against the wires.
