    LED Maglite (CREE XM-L Modification)

    Got it working- it was just my batteries that were the problem! Thanks again!

    LED Maglite (CREE XM-L Modification)

    jeffmazter,Thanks for responding! 1) I'm actually using three different batteries wired in series to power the driver- one 3.75 V 32650 Lithium Ion battery; one 1.5 V D Cell Alkaline Battery; and one 3 V Lithium watch battery. (Long story short- I meant to order two 32650 batteries but only ordered one, so the Alkaline battery and Watch battery are providing the needed voltage boost until the new 32650 arrives.)When I tested the battery pack with a multimeter, it read around 8.25 Volts. I believe that should be enough for the driver, as on the website it says it accepts from 5.5 - 15 Volts. 2) Thanks for that helpful link! I actually tested the current that the Driver was outputting to the LED, and it looks to be around 0.2 Amps, which seems like it would correspond to the Low-Power mod...see more »jeffmazter,Thanks for responding! 1) I'm actually using three different batteries wired in series to power the driver- one 3.75 V 32650 Lithium Ion battery; one 1.5 V D Cell Alkaline Battery; and one 3 V Lithium watch battery.

The pictures are of my battery pack made from the barrel of an old maglite, and a multimeter measure of the batteries voltage.Thanks again! :DMU5ICI4N

    Jeffmazter406,So, I got the Driver and XM-L LED, but I seem to be having a problem. I can't switch out of Low Mode! Every time I wore my LED up, it remains on low mode and blinks every 5 seconds or so. I believe that this low-power-blinking is supposed to be for when the driver overheats, but obviously that can't be happening! Any idea how to fix this? Thanks.

    OK, Thanks! I'm thinking of using your mod for a high-powered bike light I'm building :)

    Great instructable! Does anybody know how one would switch "modes" (low, medium, Hugh) with this LED driver?
