OK, thanks I will look it up! But as I need some 26650 too, I might buy from intl-outdoor. They use Singpost on packages with tracking number, which takes just a few days to arrive in Sweden.
I ordered the JM26 from there, and here’s how fast I got it:

2012-12-30 13:57 —> Arrived in Sweden
I dunno what FastTech uses, it’s great if they use Singpost or HKP though.

No problem!

I don’t know actually, I’ve also been thinking about that. Can someone else confirm this? Would be good to know, so that I know what to buy. I’m not at home so I haven’t got my DMM…
I will have a look inside my SL3 and post pics later. The SL3 is 4.5A, so it will be interesting to see how they differ, and might help in knowing what to do to get more power
Update: The guy living here had a multimeter! (Dunno about quality though, lol) On full it draws 3030 mA, so those are 380 mA chips indeed. I’ll probably just add one more then :bigsmile: Feels like I’m pushing the XM-L too hard at 4.2A hehe!
I wouldn’t worry about it getting too hot I mostly use it outside and it’s currently –22°C here (–7.6°F). –30°C to –40°C isn’t unusual here (–22°F to –40°F)
Which they are not. They are jsut bling factor. The center golden part of the circle, the stars and the masked part of the circle are all one same surface for the positive contact which leads through the vias on the other side of the board where the red wire is soldered.
So you have 3.04A total in the design. I would recommend adding 2 350's or 2 380's, anymore won't do you much good - just verified that on a modified Crelant 7G9 - I dropped 4.56A (measured 4.50A) down to 3.80A, dropped 2 380 7135's, and the ceiling bounce test saw no difference at all. In theory, the XML's reach their peak at 3.5A, but I go for 3.7-3.85A, assuming there is some loss going to the LED.
Buzz out those spots to see if they are trully parallel with the rest of the mounted 7135's, if so, use them, measuring after will confirm they are soldered ok.
Slacker. There is no question at all you should be adding the full compliment of 3 chips. If your not happy you can always remove 1 or 2 chips. We need to have before and after night shots as well. Thanks.
) work in the real world myself. He shows a peak starting at 4.1A, but very little gain above 3.8A or so. Haven't come across any corraborating evidence in real flashlight tests.
Seriously I would try one at a time and check for heat build up. I have no idea what the heat sinking is like on this flashlight. The hotter the LED the less efficient. Before and after shots with the same camera settings will give a good idea whether the light is working better or not. 3 amps is the sweet spot for output and battery life. Good luck on your mission.
