I was an early adopter thinking it would save a bunch of money in the long run. I went all Cree and happened to have a few Philips. The Philips are still standing tall, one burned out of the two after like 7 years. However there's these eco incandescent lights I installed in my parent's bathroom that are connected to a standard fixture powered trough one of the Lutron Maestro dimmer switches. Those bulbs have never failed possibly going on 8 years+. I'm pretty convinced that their fade in fade out dimming when you turn on/off the switch makes a graceful ramp of current that the filament never gets shocked to suffer rapid thermal expansion that eventually fails the bulb. Cree has a good 10 year warranty though, I've sent in boxes of dead bulbs to them. However many substitutes are dying out too and they're included in many of the replacements that are going back for my next batch.
