  • KEDSUM LED Shop Lights: Cheapnification Thereof

    As the basement’s fluorescent fixtures and lamps gradually die, I’ve been rewiring the fixtures for LED tubes, all bought from KEDSUM through Amazon. The first few batches looked like this:

    Kedsum - good LED lamp
    Kedsum – good LED lamp

    The most recent two batches seem cheapnified:

    Kedsum - poor LED lamp
    Kedsum – poor LED lamp

    The tubes show similar changes, going from a stylin’ version to a simple cylindrical cap:

    Kedsum vs Kedsun - tube end caps
    Kedsum vs Kedsun – tube end caps

    The most recent carton label might lead you to think they’re counterfeits, but it could just be a simple typo:

    Kedsum vs Kedsun - LED lamp carton
    Kedsum vs Kedsun – LED lamp carton

    There’s absolutely no way to tell what you’re going to get from any vendor on Amazon (or anywhere else, for that matter), so there’s no point in returning them, but I’d hoped buying “the same thing” from “the same seller” would produce a consistent result.
