Just installed these. Really simple. My concerns were the size and brightness. They seemed small. They  are small powerhouses, I have five bars and they are plenty bright, I run them on click 8 of 10 , I love the motion sensor on/off with a wave of the hand. two per cabinet are awesome, one is probably plenty. The brightness is great, the color at 2700k is perfect, and the installation can be as simple or as complex as you want... double stick tape or wood screws.. all included in kit!! 10/10
