Thanks mrs, but, should be under 3mm - 2.9464 to be exact 
. 116/40 = 2.9. I use www.convertunits.com.

Tom, dont remember if it was this thread or the original GB thread but you posted that you thought you could get around the same 250kcd as I got from an XP-G2 with an XM-L2, just wanted to say thanks for motivating me to take mine back apart and put the XM back in (a U2 1D dedomed), I just did 5 readings in a row (cause I simply couldnt believe the results) and its now doing an average reading of 268k at 1m (measured at 5m) and the max reading was 273kcd!
I’m gonna be going to my buddies poll barn in the next few weeks where I can measure at 15m in total darkness to see if it focuses any more at distance.
This is currently the farthest throwing light I’ve personally owned (tho I’ve built a few Courui’s and resistor modded an SR91 and a TK75 for customers) and its gotten me addicted to throw (use to be a flood guy).
I also went ahead and ordered several more Y3’s for lights to build for stock, I have a red PT121 I’ll stick in one for a hunting spotlight (legal in specific areas here on ’yot’s)
Cool! All good. a 1A may do a little better, even. Dunno - I got my first GearBest Y3 and it's disappointing, stock. It's not as focused as the other Y3's and does lower in lumens and a little lower in throw. I think the reflector doesn't sit as low. Been checking all sorts of dimensions and that reflector dimension is the only thing I see. The lens is a bit foggy and I can't get it clear, but subbed it out with a spare Y3 lens and no difference. This one has some differences:
- a flat matte finish where the older ones are more glossy
- a thick green GITD o-ring in front of the reflector where the old ones had a thinner black one. Maybe they were trying to make up the gap
- a green GITD tail switch boot instead of black
It's almost a full 100 lumens lower OTF (~730 instead of ~830), but amps is still about the same - 2.5A or so. Might simply be the LED or combo of things - maybe they used a U2 bin before, maybe the thicker o-ring is hurting output. The tint seems to match - cool white, like a 1A.
Hm, you just described my group buy Y3 exactly. Strange.
Hi guys, is the first time that a buy from Gearbest. Normally how long it takes to receive the goods? 30/40 days as usual?
My Y3 was ordered Sep 3, arrived Sep 22 - 19 days. Haven't had a China package arrive in over 30 days in a long time... Been as short as 10 days, more typical is 17-20. Is your glass 1/2 full or 1/2 emtpy, or is your light bright or dim?
Read threw the SingFire S1 clone thread for more info. Personally the 2 gearbest orders I’ve placed have both arrived in ~20 days but other people have had much different experiences.
Thank you.
10 days will be a super super fast deal. Last order from China take 46 days to arrive in Italy (with custom). 17-20 day still ok.
To know if my glass is 1/2 empty/full must wait 
20 days ares till a good amount of time. It’s not bad. Ok, let’s wait!! Thank you too :bigsmile:
Anybody know if is possible to change the side switch?
I really don’t like it white/plastic; grey/metal will be perfect.
And, if it’s possible, is an hard work/mod to do for a noob like me? Thank you 
From Nederland Post tracking: the flashlight in on his way, country of destination: Italy 
The 5 extension tubes, country of destination: Spain :~
Are the Y3s from GB showing up with minor scratches like the ones from CQG?
Mine was not perfect from GB (not too bad though) - I'm thinking there may be the same issues, dunno til we hear more feedback.
I'm not in a position where I can check my Y3's for battery length but can speak from experience that it is impossible to build a light that covers all battery scenarios in multi cell lights. Even single cell lights can be difficult with a single spring on one end of the battery. 18650 batteries start at 65mm in length and can go over 71mm in length. That's 6mm for a single cell that the light must cover, 12mm for two cells etc. As a rule flashlight manufacturers use the shorter length to make their lights which is fine if you use short batteries but not many of us do especially where we use protected cells in multi cell lights. As some have found out this light looks like it will accommodate the shorter batteries only. HKJs web site is probably a good place to start as it has measurements for most of the popular batteries.

Again -- single cell, I use KK 26700's -- longer than any 26650 protected cell around. Even the MOLI 26700 I've fit in a Y3 and used. Once you plug in an extender, different story... It's the extenders, not the single cell light.
Agree
Ordered 3 extensions. Want to use three KK26700 in the Y3. Will modify/machine the last extension to allow for extra length. If the last extension ever shows up in the mail. It’s been almost 6 weeks since I ordered.
6 weeks is bad - close or at the PP cutoff. I'd open up a dispute within 2 days of the limit.
For me, 6 weeks to arrive in Italy is normal, unfortunately :~
Arrived!! It took 25 days, not so bad
The extension tubes where inside the same pack of the flashlight…So the second tracking only for they was not my.
I put 1xC Alkalines battery, but it is too short. Put 4xC Alkalines (2 not fresh, 2 new) the flashlight blink, unusable. Put 3x18650 and it run very well! I’m waiting 1x26650, can’t wait
But, I’m asking if it does not run with 4C Alkalines, with the others 3 extension, so others 3/4 battery, it will run or it will blinkies?
My extension tube arrived... before Yezl Y3. Damn.
First try 4x fresh.
