My master bathroom is quite large and has two mirrors with six lights each. I put all 12 new bulbs in at the same time. My wife really liked the warm white color, but I still found it a bit boring. I switched my mirror to 4000K bulbs and it helped. She has hers, I have mine, everything works. I put the other six 3000K lights in the smaller kid's bathroom and they work great. I noticed that for some reason these bulbs make a slight buzz. I don't have a dimmer either, so it's the bulb itself.
