    Home Depot CREE LED bulbs are garbage

    CREE bulbs are poorly designed and poorly made. Why shouldn't I buy better light bulbs from Amazon?
    There is a much greater selection of high quality LED light bulbs from Amazon.

    just because you are stupid doesn't mean that other people are stupid, too.

    • Try one dude - it's the best bulb available by quite a margin.

    • I'm getting the feeling you don't like Cree for some reason

      • Oh, and NONE of them have the warranty that CREE offers.

      • Some of the bulbs above are NOT dimmable. Some are more expensive than the CREE bulbs. All of them do not have the form factor of an incadescent bublb of the same type, makling it NOT a candidate for glass globe or table lamps with shades because the light is directional for the most part and does not offer coverage at it's base.

      • 1 / 5 Audible hum and flickers
        April 7, 2013
        9-Watt (60W) A19 Daylight (5000K) LED Light Bulb (1-Pack)
        Jimmy from Allston, Boston, MA 02134, USA

        I purchased this Cree daylight LED 60W replacement light bulb with the Hampton Bay Upright Accent Lamp (SKU 494 599) at the Home Depot. The Hampton Bay lamp advertises "3 Level Touch Control" and the Cree light bulb advertises "Dimmable".

        While the two are able dim (3 levels + off), the Cree light bulb makes an audible humming/buzzing sound when it's dimmed. At full brightness, this Cree light bulb still hums, but the tone is higher and less audible. Note that the Cree light bulb did not hum when used in a different table lamp (without dimming capabilities), but the Hampton Bay lamp didn't hum when used with a 60W incandescent bulb either. This leads me to conclude that the Cree LED light bulb and the Hampton Bay lamp don't work well with each other, but I don't know which one to blame.

        Another problem is that the combination visibly flickers occasionally (this is in addition to the invisible, high-speed flicker shown in the attached photo), sometimes for extended periods of time. Once again, like the humming, this problem does not appear when the two are used separately.
        As for energy efficiency, as measured by a Kill-a-Watt electrical meter, the bulb alone consumes 9.5W (still good, but 0.5W more than advertised). (I know the Hampton Bay lamp itself consumes an additional 0.4W, but I've accounted for this by using a different light fixture).
        The Cree bulb's power factor is a respectable 0.97 when fully on, but when dimmed (in the Hampton Bay lamp), the power factor goes as low as 0.33. This low power factor means that it's less efficient for the power grid.

    • Do you really think that investors take advice from a rambling idiot? And now, your an engineer? Have you not seen the reviews of CREE's bulb? It beats the competition on EVERY level.

    • Perhaps we should listen to him he knows stupid and garbage better than anyone.
