We moved in to our house 12 years ago now and installed all LED lighting. I have not counted how many bulbs, but in excess of 100. Some are on timers outdoors and are on 4-5 hours every day, the ones in our primary living room/kitchen are probably on closer to eight hours a day. There were perhaps three failures within the first three months. Then none, for nearly a decade, except for the bulbs in an enclosed ceiling fixture in DW's office. Those are on most all the time and failed about every two years. This last time I replaced them with enclosed fixture rated bulbs that had not previously been availsble. It's been three years so far, for them.

In the last year I've had four dead bulbs in those rooms where the lights are on all the time I think they are on average meeting their predicted lifespans-- lots of them are at 20-30,000 hours of use now.

All of the bulbs I installed were from either Phillips or Cree (Phillips for spot/flood bulbs and candelabra base, Cree for standard bulbs) Because I wanted high CRI (95+) they tended to be among the most expensive bulbs available. Where I volunteer they used a lot of the bargain basement no-name or discount bulbs, they have not fared well at all.

So yes, I think there are differences in quality, especially with regard to heat tolerance, and heat is clearly the enemy. In the enclosed (hot) fixture the same bulbs lasted ~20% as long as in an open fixture. I'm hoping the enclosed fixture rated bulbs will do better, too early to really say, but they have outlasted the regular bulbs

I'm happy with the choice to go 100% LED in the house. In my shop I used T5HO fixtures because they give a lumens/watt efficiency very close to LEDs but at the time I bought them provided a whole lot more light per fixture, lowering fixture and installation cost. Those lamps are on 9-10 hours a day, seven days a week (~35,000 hours) and I just noticed the first one starting to flicker. They are clearly dimmer now than when new. Also Phillips bulbs in those fixtures.

I'm not going to give you brand-specific advice, but I will give you my experience. I have quite a few LED bulbs in various fixtures around my home and have had very few fail prematurely. Some of them are going on 8-10 years now. I don't think a lot more money necessarily buys you better quality or longer life. I've bought many different brands: Feit, Sylvania, and many other brands on Amazon that were not familiar to me but got high reviews.

Where have you been using these bulbs that failed? And have any of them been in applications where you have dimmers?

As appropriate, check that the bulbs are approved for (a) use in a fully-enclosed fixture, (b) use in a damp or wet area, (c) control by a dimmer. 1000bulbs.com has all this information for the bulbs it sells. If you're using a dimmer, be sure it's LED-compatible. Lutron LED+ dimmers are the excellent.
