I read many reviews before choosing these Amico LED downlights for retrofit and I am very happy with my choice. Pros: 1) 12 packs were well packed and organized. 2) Grand Prize for Light. 3) Installation was easy if your lights have spring latch holes. Mine did. I quickly installed 20 of these. I watched the installation video and found it very helpful. I recommend putting the E26 adapter in the socket first and then plugging in the light. As a result, the plug could not be twisted. 4) All fixings fit snugly to the ceiling. 5) Each LED was a dot and lit up immediately. I like the 3CCT options and will tweak them later. I will also install dimmers later and see how these lights work. In my opinion, this was the easiest and most affordable upgrade for my lighting needs.
