    Involvement:General (knows how to use it) - Ownership:more than 1 month

    Pros:

    I haven't measured exact output values but, on high, this driver powers an LED as brightly as another driver from here that also has a high output of 1200mA... In other words, it's bright :)
    Low output is a great (I'd estimate 15 lumens with a Seoul U2SVOH LED)
    PWM flicker can not be seen using the high output.
    The driver does not get hot when being powered with a 6V or 8.4V source.

    Cons:

    The PWM frequency of the low output is LOW. Flickering is easily seen when the light is moved. Very annoying.
    The order of outputs is bad. Low-Strobe-High.. What's the sense in transitioning through strobe before getting to the high output??

    Bottomline:

    It's a good driver to use with 2 lithium cells. Flickering on low is bad and the order of the modes could be better however, it doesn't change the fact that this is one of a handful of 8.4V drivers available here.
