I have installed over 30 of the 6" echo smart LED bulbs from Home Depot that come with the trim built in. They look amazing! They are indistinguishable from incandescent, they are cool and they dim extremely well. I could not be happier. And on LI they cost $22 (and that's with the trim ring). It's not the best pic, but you get the idea. The color is perfect too, soft white:
