The problem I have with Crees is th form factor. We have recessed lighting in our kitchen, mostly R30, and the fixtures are 40 years old, certainly superseded by newer standards. Regular R-30 bulbs fit perfectly. The Cree equivalents take some work to fit right, especially the ones with the built-in bezels.
That said, I love the light they produce. It's a bit brighter, and only slightly whiter than the light the 65W incandescents put out, at a fifth the power consumption.
I have one question for the pick-your-color manufacturers: Have you ever consulted an interior designer? The colors of paint, fabric, etc. in a room are all picked with specific lighting in mind, both natural and from lamps. Start futzing with it, and things will start looking crappy. Ever wonder why a hotel room looks fine under CFLs but the same CFLs in your bedroom make everything an ashy grey? It's because the colors in the hotel room were picked specifically because they complement the color spectrum put out by the CFLs.
I'm looking forward to the day not far off when I can have all LED lighting in the house, but I have no desire to make radical color changes (except for special applications people have mentioned ike aids for the deaf).
