Those Cree/Home Depot bulbs were brand new this spring (2013). If you've got LED bulbs that have been going for two years, they're probably something else.
The oldest ones are whatever store brand Home Depot dropped under $15 first. Ecosmart maybe? That's when I started replacing CFLs. I switched to only buying Cree when those dropped under $10 too.
