I bought two sets of four lamps (3 inch, 5W, 3000K), one set for the top of the bed in the wall alcove and the other set over the table. Installation was easy, I used a 2 5/8" hole saw and it worked great for 3" lights. I have Murphy bedside lamps on a touch switch dimmer and they work with no flickering. I had an issue, one of the power supplies was making a faint oscillating noise. I contacted YGS-Tech and they quickly sent a replacement and the issue was resolved. I am very happy with my purchase.
