Bought 11 WF6 30K LED lights for a project with minimum ceiling thickness. They work great for that purpose and look good. The only downside, and I should have looked at the compatibility list on Lithonia's website, is the availability of compatible dimmers. I tried both the Leviton DZ1KD and Leviton DZ6HD, neither of them worked and produced flickering lights at almost all dimmer levels and in all programmable light modes (incandescent, CFL, and LED). What did work, right out of the box, was Lutron Caseta P-PKG1W-WH-R.
