The idea of having multiple color/temp choices was very appealing, especially for the price. I bought 24 of these to install 22 at my mother-in-law's house (2 extra for future mishaps). I installed 17 of these today and decided not to mess with the install anymore after all the headaches. In the first box of 12 I had two with broken switches and three that didn't look like 4000k despite setting them up. Three looked warmer than the others and were brushed aside. Luckily I had enough in another box to finish two rooms. I also don't recommend them due to the spring clip design. Other manufacturers of retrofit lamps have better solutions. I do not recommend these lamps and I encourage you to consider another manufacturer.
