1) The modded switch will also need to have 4 wires as shown in the referenced threads right? (as opposed to two for the direct drive option)
2) How and where are the 4 leads coming from the switch wired up? Do all 4 go to the driver and LED assembly, and are the connections marked?
This looks great wish I had a mag.
Does anybody see why somthing like this could not be made for the M3 ?
I would love a triple XM-L T6 drop in for a Surefire M3 head am I dreaming or could this be done. ?
Cree states that min Vf for each XML is 3.35V at 3A. So the triple should run in regulation from 4.2V x 4 = 16.8V till 3.35V x 3 = 10.05V.
Buck drivers typically require some amount of extra voltage above Vload to reach regulation. Plus, there is also parasitic resistance in the flashlight itself and at higher current loads you'll get noticeable voltage drop from that as well. So you might need at least 2V above Vload to stay in regulation, meaning the triple will stay in regulation down to perhaps around 12V, or about 3V per cell if you use 4 Li-ions. That should be fine. At 3V/cell under load, you're probably close to the end of each cell's capacity anyway.
Hello Der Wichtel,

Thank you,

That's not the case with this buck driver. It will stay in regulation near Vf and goes into direct drive if the voltage is too low
Please let me know when you get the neutrals in!
Thanks!
