Yeah i tried those and they are absolutely the same as Efest 4200( real capasity is 4300-4450 actualy, at 5a load)….i think they could be rebranded Efest cause its absolutely the same, i bought them only once 6 months ago but the shipping time took forever

I tested so far Enerpower 4700 mAh , all Efest and Keepower 26650 models, Trustfire too, have several Ultrafire and i dont wanna talk about , i have currently even Sony US26650FTC1 3000mAh LiFePo4- the best considering high amps is Efest 4200

Those Panasonic 26650 in Aliexpress seems to be fakes, at least 2 that i bought were

Thanks Mitko. May I ask what device you use to test your cells?

Selfmade one, well am i a power engineer Smile Its actualy quite simple

Plus, you can always test a battery on a DD driver fresh started, at 4v, at 3.8 and so on, thats the method i used before i made one

Hey Tom, i just saw Kaidomain has a 58.6mm AR glass, have you tested it?

Ohhh - I am so freak'n spoiled by UCL's and UCLp's, I find disappointment in all the other so called AR lens (cheap ones) out there. I'm with Dale on this. I did try pretty much all of them CNQ, KD, IOS, FT, etc.. - All are beaten by Chris's at flashlightlens.com.

Think CNQ had the Y3's - tried those, maybe not the KD's specifically, not sure.

are you using 6v led?

i am running 6v xhp50 with this driver and resistor mod and its around 3.8 amps with 2 cells. with one cell, xml2 and resistor mod i could only get 3 amps.

The way I understand it the Y3 is a buck driver. I am close to 2.8A with TWO cells at the tail which after losses it should be close 5A to the XM-L2 emitter. To unleash the capabilities of this driver add a third cell. In my case three cells only increased weight and capacity. I am running 3 26700 King Kongs on my HX 1175B1 driver with the MT-G2 witb a tail cap reading of 4.6A and imagine that works out close to 6.5A. But I claim not to be an expert. Wink

my Y3 has always been different. the driver in mine doesnt buck. never have understood why. i have burnt a couple of xml2s trying to run 2 cells. that is why i got the 6v xhp50 in it. i was having trouble with my meter but i retested it at the tail and it is 4.27 amps with 2 not fully charged 18650s.

Quick question fellows: tube thread size?

I've been looking for an extension tube which I could lego with, they're selling this Y3's extension tube at FastTech, yet no one has answered my inquiry there yet.

It seems to be M31×1, comfirmation?

It seems to match the picture here. I haven’t heard of copies of this light being made.

If you are think'n of using it for another light, I dunno what M31x1 means, or how to verify it. I got Y3 extension tubes, but not from FastTech, so dunno if it would help.

Tom E:

ISO metric screw thread @Wikipedia

In essence, M31×1 is a metric screw thread designation equal to a male thread of 31mm outer diameter and 1mm of thread pitch.
