Today's lumen lies

  • sheepish Top 10 Forum Poster Monday, October 09, 2017 10:17 AM Reply

    Emitter Brand    Cree    

    LED Type    XM-L2    

    Emitter BIN    L2    

    Number of Emitters    1    

    Theoretical Lumens    2000 lumens    

    Actual Lumens    2000 lumens    

    Working Voltage    3.7V    

    Current    3A    

    1 single-die LED run at 3A and it makes 2000 actual lumens. Only in China!

    Cree says that LED and luminous flux bin at 3A makes 920 lm.

    This isn't actually the only lumen lies today - sku.483237 incorrectly claims to have an XM-L2 and an output about 30% higher than Cree's data for an XM-L.

    DX has found a new way to deceive customers:
    Use reviews for different products that have not been bought
    by the person who wrote the review.
