  • Very good 2 Li-ion Driver

    Involvement:General (knows how to use it) - Ownership:1 day to 1 week

    Pros:

    May be it is the first driver of DX which shows a better performance than advertised. I got 1.8A output current with two Lithium cells & one XM-L T6 led (output@3.42 V), on the other hand while using 2 XM-L T6 leds in series the output current reduced to 1.1 A with output voltage of 6.8 V. Both the result are off from High mode. The driver self not getting heated on high mode also which is a great symbol of high efficiency.

    Cons:

    Not a constant current driver, if it was a cont. current driver with a combination of 2 XM-L T6 leds the efficiency would have been far better and the light lumens would have been much higher.

    OtherThoughts:

    Would have made with constant current characteristics for a higher output. DX should release a same sized driver for bike light with a full current compatibility (i.e. 3000 mA constant current) of XML-T6/U2/U3 emitter.

    Bottomline:

    I don't get any bottom line till now. I will rate once again after use of a couple of months.
