    They are 3 watt leds , but most of the time leds are not driven at peak.

    watts is amps x volts

    so a 3 watt led driven at 700ma with a drop of 3.5 volts which is about normal would be 0.7 x 3.5 = 2.45 watts

    The picture is right off of e-shine's website. Either this is a US front for e-shine, or they are reselling the e-shine fixture, or e-shine is making them for them. Likely the latter of the 3. Either way, the picture is of the 50x1W grow bar, not the 25x3W one, which e-shine still sells so I don't think you're saving much, maybe some shipping cost.

    WAK - doesn't seem to explain;

    Description: 25x3 watt using 13 1watt Epistar 660nm red and 12 1watt bridgelux
    455nm blue
    Or

    50 watt using 45 3watt Epistar 660nm red and 5 3watt bridgelux
    455nm blue
    But I am LED ignorant so perhaps it does make sense if you know what you are talking about.

    Oh snap you're right, their pics and wattages are all messed up. The 100W array shows the 100 x 1W e-shine fixture, but then says is it 50W using 50 3W LEDs, which are probably run at 2W so that makes sense, but still. This site now screams that it's a front for a foreign company. US based companies (for the most part) actually review their site wording.
