In case anyone is interested... I just saw the CREE CR6 come up on the Home Depot web site for $49 under the Home Depot brand EcoSmart... but it is clearly the CR6. I spoke to CREE and they said the only differences between the HD version and the CREE retail version are 3 yr warranty instead of 5 yr and 35,000 hours instead of 50,000... and there are some different internal parts. All other specs look identical. I would be curious if anyone buys one of each and takes a look inside to see if there are really any different parts... :) BTW.. Home Depot has "tons" in stock, they say.
