Just got my Trustfire TR-J12 from this same Aliexpress retailer. All arrived in perfect condition and very well boxed. Using my 2x26650 Trustfire 5000mAh’s charged to 4.19v, on HIGH mode I get 4.10a
Finally I have a good working 26650 light. Thanks for posting about this retailer, they are as professional as it gets and sell real Trustfire products.
Just took it outside and put it up against my DRY NW on Turbo and somehow my J12 beat it. I came inside and did a ceiling bounce test between both to see what the meter showed. The Dry read 630 lux and my new J12 read 805 lux under the exact same conditions. Perhaps the fact the Dry is NW tint and the J12 has a slightly cooler tint must be the reason for it being slightly brighter. Whatever the reason, I find it amazing the Dry got edged out.
thanks richiee i ordered from ali express 1 of these as well.

I’ve been trying to figure why there isn’t more hysteria about this light at this price. Great light at a great price with a proven vendor. I guess people prefer the form factor of the King better…
After seeing the issue Kramer had with his tail-spring, I decided to modify mine before a problem came up with it. I noticed the switch was the same on my Skyray 856 except the 856 uses a stronger gold plated spring soldered to the switch rather than a thinner chrome plated version as on this J12. Since my 856 has a bad driver, I figured I’d just switch them out. Works great and I doubt this heavier duty spring will suffer from any heat issues.
I can think of 2 main reasons. Size factor first and foremost. Its just a pain to pack a 2-3, 26650 light, IMHO. I think the bigger difference though is how each design makes use of power. The J12 needs 3.6 - 7A from each of its cells in its smallest configuration. This IMHO pretty much rules out 18650 cells as a safe alternative. This is a very difficult load for even the best 18650 cells. Even 26650 cells, if continually deep cycled with this extreme of an application will start to feel the effects. Exactly how (and when) remains to be seen… increased internal resistance, diminished self discharge performance, decreased capacity.
Because of its power extremes I don’t think the J12 is a light suited for a battery novice. I don’t think its the kind of light like a 4D maglite where you can just load it up and run it till’ it dims, at least not repeatedly without unfolding some element of risk. I for one also don’t think its a safe practice deep-discharging protected cells and tripping their circuits. So I think the J12 is the kind of light that requires some disciplined use… But thats just IMHO.
I have one of these on order from the same supplier - so far 13 days and counting for delivery. The tracking number they supplied me does not work though…
