Tech In Plain Sight: Incandescent Bulbs
(hackaday.com)
This is a most excellent place for technology news and articles.
I've been using GE Relax HD most recently. I don't remember when I bought them, but it has been at least 5 years. I haven't had one die yet.
(All the Cree bulbs I used before these died quickly.)
Edit: I have read that LED bulbs usually die early because of their driver circuitry running too hot. If you are able to give yours better ventilation, it might help.
