I just had an addition built and did some remodeling, putting all recessed lighting in, a total of 25 lights. I went with the Cree LR6C. The LR6 does a great imitation of incandescent light, but the only thing I find good about the red-yellow incandescent light is that we're used to it. I and my wife really like the somewhat cooler (about 3400 degree color temperature) LR6C.
The lights screw right into standard recessed fixtures. I used Halo, and highly recommend them for ease of installation. You can get the LR6 and LR6C and fixtures with the two-pin base, also, if your local code requires it. I believe California, for example, now requires lights in new construction to have the different base so incandescents can't be retrofitted. That's not a requirement here, so I went with the standard screw-in (Edison) base.
We love the color and the brightness. They're spec'ed at 12 watts, but typically measure more like 10, and they're at least as bright as 65 watt incandescents. I've got them spaced roughly 5 feet, and it's bright -- I measure 250 - 300 lux at waist level. Conventional dimmers (some, anyway) will dim them to about 25% intensity. They don't change color as they're dimmed. And of course they come on immediately at full intensity -- there's no warm up period like a compact fluorescent.
The thing that sold me about the Cree is the way they control the color. The light has a number of white and red LEDs, and a color sensing element. The sensor automatically adjusts the relative outputs of the white and red LEDs to keep the color constant. Without this constant feedback control, a lot of lights using this scheme will change color over time as the LEDs age differently. And I can't perceive the slightest difference in color from one light to another.
Love 'em, and highly recommend 'em.
