    Involvement:Expert (understands the inner workings) - Ownership:less than 1 day

    Pros:

    bright!

    it has a good beam

    small case

    good case quality and looks good

    5 modes

    Cons:

    the brightness is different with all accapted batteries - 1 AA is the worst, 2 AA is much better, but 1 Li-Ion 14500 is the brightest.

    the case gets quite warm on full power.

    the 5 modes are changed by switching the switch (soft touch on the switch or by turning off and on), this is a bit aggravating because when the lamp is turned on, the mode is always a other.

    Battery life is not very good with 14500 li-ion cell on full power (i think about 30 minutes, not tested yet)

    OtherThoughts:

    the lamp is nice, but when the LED driver will be a constant-current-source it will be better, because the brightness will be constant when the input voltage is changing.

    ATTENTION! When you use a unprotected li-ion cell, you will not know when de battery is low (2,5V) and deep discharge is not good for the cells.

    Bottomline:

    Nice flashlight for the price.

    When you search for a small light with high brightness, take it and use 1x14500 or 2xAA NiMh (Sanyo Eneloop recommended, i´ll test GP ReCyKo soon (next DX order)).
