    Impression:Great price,DOA;

    Pros: Very cheap considering the output and lumen produced.
    Cons: The way the polarity is marked is somewhat confusing but easy to figure out with a multimeter. First unit only had 6-7 working emitters, second had 60-70% working. Third worked to 100%, at least for now.
    Other: At 33V you'll need about 11ohms 10W resistors for simple hookup.
