Well I bought this bulb in September and now it's February. The lightbulb started blinking in January and then went out completely. Far from 9.1 years. Even if it was on all the time, which it isn't, almost not at all. I'm consistently disappointed with CFLs and LEDs, especially considering how much you're paying. But CFL is worse! They just don't seem to last. I would try to get a guarantee but you have to go through so many hurdles - one company (not sure about this one) had a 10 year guarantee but you had to have the original packaging and receipts. Come on, who keeps the original packaging for that damn lightbulb? It just excites me.
