I have swapped out over 20 6" cans in my house with the CR6 CREE LED fixtures from HD over the last year. I was walking through local store yesterday and see that they now carry a CREE 4" LED fixture (similar to the 6"). I don't even see it on the CREE web site. It is more expensive than the 6" ($35), but I have 4-4" cans that get a lot of use and I have been looking for a good LED bulb that dims without flashing, and fits properly in the 4" can/trim... so I put in a couple of the 4" CREE LEDs and they are great!

Interestingly enough, they are rated at the same light output as the 6" version, but 1 watt lower power consumption. I am wondering if they use a newer generation LED in them... anyone seen them or have any further info?
