    double xpg w/ 2800mA driver?

    I am considering a double xpg light using ShiningBeams cheap 3 mode driver. Specs for the driver are 2.8V - 6V battery input. 3 mode output 140mA/1,000mA/2800mA. I assume I can use this driver but am unsure on wiring to achieve half the mA to each led. Any help?

    Parallel only.
    And, if one of the LED dies, second will get 2,8A immediately ( = nicely fried XPG).
    I would use single XML with this driver (or XPGs with proper driver).

    even if you modified for half the current, it would still be a pretty poor selection of modes?

    Thanks guys, the single xml build sounds like the way to go. I was just thinking of using up a couple of xpg's I have lying around.
    Is there a cheap useful 3 mode driver for a couple of xpgs?

    You can use shiningbeam's 1400mA (4*7135) driver and wire 2 xpg's in series using the poorman setup. You have to use a 2s (8.4v) battery.

    I may have got my hands on the last 3 1400mAh boards from shining beam.
    Just got em in my hands yesterday, and checked their site, and they are no longer on there.

    Now I just need to wrap my head around how to wire one up to 2 XP-G's.
    It's hard for me to understand without seeing a diagram, and the only diagrams on CPF are for 4 XP-G.

    EDIT:
    Download over at CPF cleared the wiring up for me. I think I got it now.
    Here is a link incase anybody needs clarification on how to wire up 2 XP-G's in a poormans setup. Post #263

    Sorry for steering this in a different direction, but it seems like the info could benefit the OP.

    Look, whatever happens, don't fight the mountain.
