    A lingering question in my head about these Amazon and Home Depot bargain bin products. The ecosmart 80cent bulbs I have commonly fail by just becoming dim just like this guy’s. Well I can’t expect too much from bottom dollar quality.

    TL:DW
    • Amazon product that failed after 15 months with the seller nowhere to be found, didn’t work because of a bad connection.
    • ecosmart likely a shorting resistor, not enough voltage from the driver chip getting to LEDs that are working just fine.
    • utilitech pros had better heat dissipation and more parts, but found no clear failure mode and he busted the thing anyway diagnosing how it handled mains voltage.
