    n00b question about XM-L, driver and battery

    Hello all,

    I'm looking to build a single LED XM-L type design, based on one of the many sled designs I've seen on the forum. I was planning on buying an L-Flex to drive it, but I'm a little uncertain about which battery to choose?

    3.7v? 7.4v? I'd prefer to use a Task LED driver if possible, they're stateside vs a long wait time from DX, other places, etc.

    However, suggestions are welcomed re: driver, nothing is set in stone at this time.

    Thanks!

    You need a 3.7v battery with a single XM-L if using an L-Flex.
    The combination works very well.

    Taskled.com currently says nothing will be processed or shipped until NOV12. Still probably faster than dealextreme and 100x better.

    illumination supply also sell a good 3A AMC7135 based driver for not too much ($10-12 inc. postage I think), which is simpler than the Lflex but would work fine for what you need (has undervoltage and overtemp protection and a variety of selectable modes). It might also be worth PMing E1320 on Budgetlightforums as he sells custom programmed drivers for reasonable amounts. You might even be able to get a nice LED off him if you ask nicely.

    None of them are quite as fancy as an Lflex, but for a single XM-L light you might not need all the bells and whistles, then you can put the money saved towards something else, like the battery

    Illuminationsupply is currently on backorder. I ordered some 3A AMC7135 drivers a couple weeks ago (they were not listed as backordered then) and I'am still waiting.

    EL34 also sells the same 105C driver, but in the 2.8A version.
