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 Adam Wilson

I used these to retrofit existing can lights. The biggest pain was getting the old cans out of the existing ceiling holes. The new lights trim rings were just a tad too small to completely cover the existing hole so I utilized the old trim rings by placing the old trim ring onto the new fixture.I used WAGO connectors which made wiring very easy. The only negative of these lights is that the boxes are fairly flimsy and bend easily when removing the knock out plug. I used electrical tape to completely wrap around the entire the lid and box so the lid would not pop open once installed in the ceiling cavity.
