Glass plus reflectors. It is a rare light that can exceed 80% optical efficiency. Most are in the 70-75% range. Those small reflectors are real killers…
Ah yes, I forgot about reflector losses. I can’t get a good look at the centering rings from the pictures supplied, so I guess we’ll have to wait and see.
Nah, they just use random number generators 
Fasttech specs - 3800lm, beam 500m
Aliexpress specs - 2700lm, beam 1,000m
its a total lottery.........
Unfortunately, someone's gotta take a hit and review it before I'd drop that much on an unknown light.
If anyone is about to buy, check out this site for a nice price drop down from $121 to $76: http://www.shenzhen-wholesale.com/trustfire-trs700-7-x-cree-xml-t6-led-3800-lumens-diving-flashlight_sku9556.html
But…diving flashlight?? Surely doesnt look like a submersible model with a sliding switch.
what is this triple mtg2 btu shocker that your talking bout?
dude that is dirt cheap. man what if its not as bright as fasttechs….i should jump on this right now actually before they raise the price
actually, their way of payment is only western union and some other thing. and they need to email you shipping cost.
Yes you’re right. It’s one hell of a beast!
>)
Me like it a lot! :heart_eyes:
That is the most desirable huge sized multi-emtter light I have ever seen. It looks so great and bad-ass at the same time!
Have anyone ordered it?
I im skeptical about 2 things though.
-The built in bezel, it looks to be a bit long, might steel some light.
-Mod friendly for higher output?
ex sending.. unfortunately.
What does that mean?
Looks good 
Ah yeah, no free shipping, and they probably charge a couple bucks for using paypal too. You have to put it in the cart and do a “pre order” to see how much, they say “we will email it to you”. Even if its “a lot” for Chinese places, it wont be near the $50 difference in price I’m sure.
SZ wholesale has come through on a lot of my deals in the past. They have consistently had better price and when I have bough something from them they have packed it up really nice and safe and shipped it to me right fast. They get my thumbs up.
I've pulled the trigger on this badboy this morning. I can't wait to get it in my hands!
I have to say the finish, as well as the machining quality, is unlike anything I've ever seen from Trustfire. It actually looks like something Armytek could have produced. With luck a simple resistor mod can make it's performance as beastly as it's looks. Can't wait to see it in person. :bigsmile:
Cells and LED's - same as a J18. A J18 with the IOS driver and you got 5,000 - 5,500 lumens. So, for the extra cost of this light, you are getting maybe a preferred UI, form factor, host quality? Dunno, too many maybe's - if there was something more to it (U2's at least) ...
This is supposedly infinitely variable, so not sure how a driver change will work with the current switch if it really is infinitely variable.
Exactly. I hope that a resistor mod is easy enough on it. I’d be very happy with 2A/LED. More would be icing on the cake.
Did you buy it on that Shenzen site? If so, what was shipping like and total cost?
Yeah, I probably wouldn’t get it unless I didnt have a J18 and this one could be modded the same way. Still a nice light though. I really have my eye on the J20…
Do you think your mod would work well on the x100? With the nicer throw that one could really be worth it.
