Review TrustFire TR-3T6 Triple XM-L T6 5-Modes Memory LED Flashlight (3x18650)

The 3x XM-L DRY is a no-go due to voltage constraints.

The Long-Run DRY single XM-L could potentially work, if someone made a series 4 x AA holder.

your talking emiters and basic math, i thought we where talking about the driver.

why does 3 x 18650 draw less then 2 x 18650,s and why does 1 x 18650 draw more then 2 x 18650,s

as in example draw 20 amps at 15 volt through 14 awg wire it will get hot, but draw 20 amps through the same wire at 24 volt it will not get hot.

there is other examples like with 24v 4wd,s and 12v 4wd,s the diffrence in wiring and thermal fuses for extra lighting they didnt teach me in collage.

another example is voltage sag thats followed by scaling up in current draw.

im going to try this tomorrow, it seams the lower voltage has increased the current draw

That example is just wrong. You probably mean for the same power transmitting across a system, a higher voltage means less current and loss within a given piece of wire with set resistance (and also less voltage drop across the wire itself), not the system as a whole. The temperature of the wire is still inherently a function of the power dissipated within it, same as the system.

in the real world some times things differ from whats is schooled. my example was from a hobby charger main power leads.

i have a good example about the diffrence from 12v to 24v 4wd,s lighting, but its just to much for me to type are a hard days work.

ive always thought and was tought the higher the voltage or the higher the voltage can be maintained the less current draw that is needed to maintain its given requirments.

im crap with words but i think you might be getting what i mean. voltage sag might be a better example.

The confusion here is between the system as a whole and the wire. The wire is only one component within the system. The wire is dropping 24v. It has a set resistance and its power dissipation is directly proportionate to the current across it. So for a system that maintains a given power usage (like our driver above, which is specifically designed to function in this way, not as a natural consequence of a trivial circuit), it does mean that slightly less power will be dissipated across the wire. However, the vast majority of the power will still be going to the emitter.

is that TrustFire TR-3T6 3800-Lumen?

Nope i dont think any of them including the dry, trustfire and the sky ray come close to 3800 lumens.

but you should know that as in your sig you have links to the same online shop.

looks like manafont sell a replacment driver for the TR-3T6

Triple T6 Cree Circuit Board Driver

it might work for the burnt out sky rays...

thanks ,i know that,tow online shop have same product,but price different。

ive been using my TrustFire TR-3T6 heaps and it is still going strong, been using it every night just about and last night we took it on another long bush walk spotting kangaroo,s and rabbits with my daughter on high all of the time.

today i tryed it on 6 AA Duracell 2650 mAh rechargeables i had to use all the extention tubes from the TR-3T6 3 x 18650 and my TR-1200 the current draw was 2.81 amps the batteries where fully charged and where 9 volt combined.

next to the torch is a 30 cm or 12 inch ruler to show the extra lengh it still felt solid, i could not notice any lose of light with my eyes and the torch still worked well but is close to the lenght of a 4 or 5 D maglite ? and could be use as a base ball bat lolls

LOL! Benckie, great stuff....

Perfect timing! My TR-3T6 I bought myself for my birthday came this morning, my birthday. :)

What an awesome light! The finish is great with no nicks or blemishes. Threads are perfect and smooth. All o-rings are the right size and seal nicely. The head is really heavy and takes a while to get warm compared to my other XM-L torches.

The one thing I'm disappointed in is a lack of o-ring for the lens. Does anyone know where I can get an o-ring (preferably GTID) the proper size for it? Did anyone else have that gasket on theirs?

Output, without a second TR-3T6 to compare directly too, seems to be the same with either 2 or 3 cells. For now I'm running it with only two but I can't wait for tonight when it gets dark! 8)

Johnny, mine didn't come with a lens gasket either. If you find out where we can get one, let us know. Besides that, it's a great light!

Happy B Day Johny Laughing

mine has a o-ring infront of the glass on the bezel and an alloy ring after the glass, then a o-ring on the head where the bezel screws onto the head and double o-rings every where else.

it is hard to see the o-ring infront of the glass as its tight but there is one there on mine, try looking hard between the bezel infront of the glass.

Will do! Hey, if this body & head is the same as a TR1200 then there has to be something out there. That body is common as hell and been out for a while. Even a Maglite gasket might fit! :wink:

EDIT: According to a Google search you can get the Mag-lite lens gasket at Advance Auto Parts for less than $1. I'm going to grab one next time I'm out. Reflectors and pills for the TR-1200 fit the Mags so the Mag lens gasket might fit the TR-1200 and TR-3T6.

I just looked and your right. It's very thin and hard to see without shinning a light on it. Oh yeah, Happy Birthday Johnny!

Thanks, Guys! I removed the lens retaining ring and sure enough, the lens gasket was hiding in the corner. That’s good news to me. I was able to properly tighten the retaining ring and all is nice and snug now. One thing I know I DON’T have is a gasket on the head where the bezel screws in. The groove is there but no o-ring. That’s an important one and I’ll have to find one somewhere.

And thanks for the B-day wishes, guys!! :)

Sweet. Thanks!

Well my TR-3T6 came yesterday (manafont) and despite being really good packaged in bubble wrap, cardboard box and bubble envelope it has lot of small nicks and bruises (mainly on head) and finish looks really delicate (far from x8)

On the bright side it works flawlessly, has really nice almost neutral white tint and it's seriously bright

On two fresh hi-max cells it draws around 2.4 A and 1.55 with three cells.

Hi there,

will it burn the driver if i would use 4*18650 batteries? ( with an extra extension tube )

best regards
