    Pros:

    The "next level" lightsource for designers,
    inventors and for other development.
    The light seems pure white in all directions.
    Can not replace Cree's on stars without altering several things but that makes it for
    other applications maybe more suitable.
    The 11V 1000mA and the better dissipation
    og the nine chips is better than single 3W chips technique 3in serie 3 strings parallel tells that 9 80 lumen/watt emitters work together, well spead over the coolingplate and about 170 degrees radiationfield, so a hemisheric emission characteristic.

    Cons:

    Not really, only for making lightbeams less suitable

    OtherThoughts:

    Waiting for a good driver for both 12 VDC an VAC and 230VAC should be pleasant.
    The current of 1A is devided in 3X 330mA wich is for a 1 Watt emitter a nice and not overratad value.
    Allthought the unit needs proper cooling , less nasty hotspots will be produced wich decays lifetime.
    Hopefully the chips insede are EXACTLY the same, otherwise NTC effects can send the best producing lightstring first to the chips-heaven because no kind od compensation (resistors etc. are being used inside. Time will learn if that gives trouble

    Bottomline:

    Nice new product, emits a HUGE amount of solarcolour light and a very good unit to update your home to completely LED lighted.
    It easilly outclasses a 100 Watt incandecent lightor a 20 Watt energt saving light with far better spectrum, because white leds produces many more colours dan fluorescent lamps do.
