I have been 100% LED for quite a while. I use a lot of different brands, basically whatever I find usually. Ecosmart, Philips, Feit, etc... and most seem to last a pretty long time. I also tend to buy 6 or 8 packs. With the Feits, I had some fail within a year or so, but when I replaced with ones from the same box, those lasted years. I guess it just depends. I have a few that have been going for 7-8 years at least, those generally being the more expensive ones that came out early on. I have a 48" ecosmart one in the bathroom that's been there for ~6 years.
