Review on Amico 12 Pack 4 Inch 3CCT Ultra-Thin LED Recessed Light with Junction Box, Selectable 3000K/4000K/5000K, 10W Equivalent 60W, High Brightness 700LM, Dimmable Can-Killer Downlight by Andre Young

Excellent 6" light set. Will buy more and try the 4" version. Dims perfectly.I had hopped these would be flush with ceiling allowing just a small hole for wires up to transformer box (installed in top floor where box could be fitted from attic.). However, you still need to cut a full 6" hole in ceiling. Sames as with a canister light. Would be great canister upgrade.But the looks greatly exceed a canister with a flat disk on ceiling and no hole visible.If they fail, (all 10 worked), replacement is just rotating some clips and plugging in, but can you buy just the LED light section?
