XM-L2 T6 de-domed
LED mounted on copper board (Sinkpad)
Increased power from ~16-17W to around 20W (variable resistor so can be changed between 1-20W total output)
Lux readings are around the 230K mark @ 1m (measured at 4.56m and calc. back to 1m)… I also tried it with a XP-G2 (de-domed on copper) and got around 300K lux (at 16W) but has been swapped back for the larger spot of the XM-L2.
So… here is what I can think of for improving it further: XM-L2 T6 changed to a U2, AR coated lens, solder braid on switch (possibly pointless given the driver type)… anything else?
A strong arm and warm up beforehand to prevent injury. Na, just kidding. Sounds good with what you have done. Are you going to post some pictures up of your mod?
Nothing much to stick up in the way of photos: you’ve all seen what a de-domed XM-L2 on copper board looks like as well as a resistor swap… not much I can do in the way of beam-shots either… if I have the time I’ll try chuck something up later.
As far as increasing amps: I am reading ~2.7 amps with two 18650s in series (~3.8Vx2) so it should be something like 5-6 amps to the LED. Anything above this resulted in flickering… something to do with the tail-cap.
