    Cree has a new bulb with a plastic globe instead of glass. It's cheaper than the glass ones, but uses more power. I picked one up to try out.

    Yeah, the bulb I had in my lamp by the couch went out after just a couple months. Cree exchanged it for me, but still, nowhere near the supposed 10 year life.

    They're getting close. Very close. I used the last of my stash of CFL's and went shopping for more bulbs last week.

    I almost got LED's. So close. But instead I bought a multi-pack of CFL's for 1/4 the price. Maybe when those run out I'll get LED.

    I have LED's in my dimmer fixtures, CFL everywhere else.

    I've just replaced all my exterior lights with LED bulbs. 4 floods that are 120W / 20W actual and three 100W / 15W actual regular bulbs. Anything will be better than the 6 month average the last floods lasted. I've started changing out the interiors for 60W / 11W actual GE bulbs that were on sale in a two pack at walmart. They work OK in a group (in a ceiling fixture), but as singles they struggle in the floor lamps

    Years ago, I got a one-sided LED faced unit, that let that face rotate to place light where you need it. If you have a proper place for such a light, you'll burn 6 watts of electricity, but illuminate with the equivalent of 100 watts....... an incredible LED light.

    Matt, I did that at work with the bathroom lights. I was replacing four 15W cfls a year because of the constant turning on and off of the lights. Since I replaced the CFL's with Cree 9.5W LED's problem solved. I have yet to replace one so far and it has been a little over a year. Exit lights were the same six 20W bulbs a year, two bulbs or 40W per unit. Put in replacement LED's 2.5W per light box in back in 2011 and not one has burn out yet. :) Total replacement cost $45 for the LED's vs buying six, $6 incandescent bulbs every year.

    I have over 55 LED's now.
    1 GE,
    10 ecosmart, BR40 (HomeDepot house brand, But not Cree)
    8 Phillips,
    The rest are Cree.
    None have burnt out.
    Only flicker in one room, with a old dimmer.

    The BR40 ecosmart were sold for a short time in HomeDepot.
    Website had lots of complaints of early burnout.
    I figured they were from heat reading the reviews.
    So I created heat sinks from dog food can lids, pushed on from the screw side.
    Used a spade hole saw bit. 1 3/8" in the center.
    And snips when the old spade bit couldn't finish the job.
    Removed the air-tite trim rings I had earlier installed.
    Finally adjusted the bulb height in the recessed can to protrude out of the can slightly.
    Worked and looks great. More flood than spot light now.


    Very Happy with all my choices. Great color and brightness. Trial and error was used.

    Hear that GE is making a new Reveal BR30 with no flicker.
    I read of a no can install LED down light also. Wish I heard of them earlier. Could have kept the ceiling hole wire only.

    Here is a good read for anyone interested in LED bulbs.

    Good observation. That's likely a common cause of early failures of LEDs, and CFLs, too. People put them in poorly ventilated fixtures designed for incandescents, which are much more tolerant of high temperatures.

    Update: The replacement LED for my failed CREE 3-Way LED bulb just failed. Two failed within about 6-7 months. I won't be buying another CREE LED bulb until they get their quality issues resolved.

    Funny you should bring this thread back. I saw the first flicker the other day in one of my Cree-equipped fixtures. Based on past experience I'll find a dead LED in about a month.

    I've started writing installation dates on the bases of replacement bulbs. I have a feeling this is going to lead to a new spreadsheet.

    Both of my failures never flickered. They just suddenly failed. Today I had the lamp on the "high" setting, and was done with needing bright light, and just wanted to click it over to "low". I twisted the switch, it went off, and never came back on. After the first one failed, I thought maybe the switch/socket in my vintage lamp were going bad, so I replaced them and the new bulb still died. I guess there was nothing wrong with my lamp.

    A week ago I swapped my minor-but-frequent flickering Cree for a Lowes Utilitech LED and haven't seen a single flicker. Same fixture, same dimmer switch, same operating conditions, same dining room so regular daily use where flicker is noticeable.

    Sigh. I had thought the Cree name would make it a good buy but now I'm questioning it.

    My Crees flicker a little on a dimmer. The Luminus ones I got from Costco are better on dimmers so far.

    Here's my review of the bulb that I posted on HomeDepot.com as soon as it failed.

    At this point I've been scared away from the CREE LED's. Not willing to try another until their reliability has improved.
