Just saw that you are from Sweden, HB012. Nice cold place! :D
Yes but as I showed you the light was not cold when starting it was 29C and room temp 25+C. But outside -4C no problem at all with heat, no drop at all in output.
But outside my broken modded fan cooled makita Bml185 outperforms the TJ12, but inside this light last longer on high, also water resistant so it's more useful everywhere :-)
Im awaiting comparison between the Fenix TK70 and this one now! But for ~140-160$ you can buy 2xTJ12 and fix them together and compete with TK70 hehe
Edit: btw the tailcap reading were 2,1A, 1,3A and 0,3A using 3x18650 trustfire 2400mAh(flames) all charged at 4,23V this should be about 27w pulled from driver.
Nice,
I already have one on order (DX)
still curious about the tailcap measurements though..
Me to
I'm going to try with 3x26650s and see if I get any better results as soon as they arrive btw...
could anybody that can see them repost the beamshots?
Well I have the TK-70, and the XTAR S1 apparently also arrived but i missed the delivery. Will be soon for the J12 too.... :)
My beamshots are really shitty quality, but perhaps 2100 will have some good photos soon? Anyway a friend of mine is a amature photographer so I'll try get either the camera or her to help me taking some real beamshots with camera and flashlight fixed on tripods and on measured distances etc.
I recieved my 3x 18650s today and I can confirm that they fit as they should, but they'll need some charging time before trying if theres any difference. Btw they fit my cheap 5$ 18650 charger from DX only 1/2 slots though, and they fit 2/2 slots on Ultrafire 188.
Those looks like 26650 King Kongs (not 18650). Please let me know if you ever can use them on TR-J12. Thanks. They should not work.
I couldn't resist it, I ordered one from DX in spite their unbelivable long delivery times :)
They are too short. You need longer (protected) ones.
I would avoid protected, can't you use spacer or longer springs?
Let's hope so. 
Too short is easily fixed, too long isn't. :)
it has to work, no one reported that problem
Are you gessing that they are or are you sure? I haven't actually tried them yet, they're still charging. But why so negative :P? If three 18650 fits then three 26650 should, they even fit each others chargers...
Bah...just put some solder blobs on them.
Do not try neodymium disc type magnets. They might short out at the positive end, should you knock the light hard while it is switched on. It's not supposed to, coz the internal is anodized. But there might be negative contacts at the front and you know Murphy's law always kicks in. 3 x 26650 gives a lot of boom, these are not IMRs. Be careful when using them HB201 and jurdiciously monitor the voltages. Do not use for long periods or leave it unattended.
These are not imr's you mean those king kongs are weaker? Their capacity and resistance are ok...
