If I had the money for any of them, since the UniqueFire UF-S7 Cree XM-L U2, is the exact same body design Trustfire uses, it would be the one I'd get. Not to mention it's a XM-L U2
Since there is only a very slight gain in lumen's between a U2 and a T6 driven at full power and these multi cell lights are very efficient and never driven at any where near full power, i don't think there will be a big difference between the U2 and a T6 7 x led except for price.
Manafont is one of my fav shop's but i would not rely of there measurements to much as they had the TR-J16 as 149.51mm wide at the head loll.
I really honestly think driven the way these multi led lights are normally your not going to see a difference in light out put the eye can see with the U2,s over the T6's.
The UF looks the same as the TR-J12 and the Keygos and so on to me. The trustfire TR-3T6 and the TR-J12 have proven to be good reliable lights and that can handle long run times with no heat sinking issues, with mode memory and dimming mode for low voltage.
I really like that driver as it has no strobe or s.o.s modes If it will run on 12.6 volt ok, you might find the TR-J12 draws more over 2 cells then that driver listed for 5 x T6 but has flashy and s.o.s modes.
Hello guys i just got the TrustFire TR-J18 for 85 bux over at lightmalls.com. I know it well not be 8000 lumens as they say so about how many lumens well this light put out in reality?
I also got this light from lightmalls, and I must warn you, it is a fake. If you got one that doesn't have any labeling, and the areas along the tube where the labels should go are flat (the genuine trustfire version is slightly curved), then you also got a fake. There are other differences to tell yours is a fake, but these are very obvious ways. Very dissatisfied with lightmalls for pulling this crap on me. :(.
Even my trustfire 3T6 outshines this fake flashlight.
My email invoice shows the correct item, but the item I got is a fake version.
Guys, also, when they say U2, they might mean in fact even T5-T4, we all know about fake characteristics, so don't rely on that for your criteria of the best flashlight!
I think the best thing to do with any of these, whether it's for a Trustfire or Uniquefire, if there's enough interest, we should contact either Ric from CNQ or Hank from IOS and have them deal directly with the manufacturer for us. Maybe we'd be able to choose which XM-L to install and perhaps even color tint. Maybe they can also have a more suitable driver installed too.
