Mine is the same 
Thanks for the teardown dchomak!
I think I recall reading that that driver is junk (I may be wrong), but the rest is worth well over $24.
Yeah. The driver is junk. Start planning.
Luckily the driver is the easiest part to fix these days, thanks to the great members here!
I just got finished with some mods on this light and driver.
First of all, I am no driver expert, but as far as potential output from this driver, I think it can be VERY good. Here is a pic of the 70N02 MOSFET that I just swapped in. The 70N02 has super low resistance when passing a lot of Amps. Look at the circuit board. The entire perimeter of this driver is a sea of copper clad circuit trace that all leads to the Source pin of the FET. The Drain of the FET is just a few mm from L-. The positive ring on the cell side of the driver is connected directly to L+ through the vias that can be seen just under L+. These are all direct connections already, unlike the highly regarded JB driver that has current limiting resistors that have to be shunted in order to get what this drive already has STOCK. As long as that FET is drivin to full ON when on high, nothing could be better. If I am missing something here, someone please point it out. Sure, maybe with the original 35N03 FET it sucked, but now it rocks.
Before
After
All of the XM-L2s are mounted directly onto 1 star that has its own traces connecting them in parallel. Nothing I could do there. What I did do was replace the 24 gauge lead wires with some 16 gauge wire I picked up at Cables and Connectors. they only had 25 feet on the spool, so I bought all they had. I think it might be silver plated copper, but I can’t be sure. They didn’t know what they had as they got the spool as part of a liquidation buy.
It’s definitely copper underneath, what I don’t know is if it is silver on the outside. They said it was test lead wire. It’s nice stuff, just not silcone or teflon.
I have yet to do the spring mod, but as of now, my subjective guess is that it is twice as bright as it was. Before these 2 mods is was about as bright as a modded 3 XM-L SRK with tail spring mod, lead mod and FET swap to 70N02. That also was a cheap, non JB driver.
Yes, that is where to get them, comfychair first gave that link awhile back.
Unfortunately that seller doesn't ship outside US. :(
Does anyone know any shop shipping those MOSFETs to Europe? Or could anyone in US please help me to buy some and send to Finland?
Have you checked: http://www.digikey.fi/
Thanks, but it's out of stock there. [If I read the table correctly]
dchomak, were you able to measure a noticeable increase in current or brightness after the mod?
Would be absolutely nice to drive this beast to its full potential.
The mode spacing seems fine after the mod? How is the PWM?
Sorry for all the questions, just excited to get mine haha.
Got them ordered via a friendly US-based forum member. Thank you very much for your help! :)

or can also an US-Member sells me one or two and send it to germany?
Our illustirous RMM has them for sale on his web site and it currently shows 26 in stock:
Here.
His shipping terms are here for outside the USA:
Here.
:bigsmile:
Thank you for this information!
just write him a PM about the shipping costs ( if i remember 15 USD for a Flashlight - a few bucks for small parts)
he is nice and answers fast!
Ah dang!
This might help you rebuild your switch

Just need a pushbutton, solder on, then solder on the wires, well after you fix the metal rim
Slowly but surely you can get your SRK back together…just be gentle with it
Good luck good sir!
It no biggie that the light is dead. I was not planning on keeping it original anyway. I just hate it when thing break when they are not MEANT to break LOL
But thank you for your concern :-)
Ugh… now I kind of regret it I didn’t buy one at the original price :Sp
