Wait am I missing something here? What is Beacon LED function exactly? What LED, main or switch? What beacon function exactly?
Beacon led as in the switch indicator. The side switch has a beacon function, correct?
That is what miller is calling the Switch LEDs in the OP on Real Issues Found.
Sorry. The LED in the switch. When you turn the light off with one click, the green LED stays lit (guess that’s technically not a beacon….told y’all I probably said it wrong)…assuming to help locate the light in the dark.
To disable, supposed to turn light back on and then immediately back off again, but not fast enough to register a “double click” for turbo.
Q8 came in the mail today! I have put batteries in it and have been giggling like a little school girl! I am saddened to report, however, that my switch led has begun to show the dreaded erratic behavior. It worked fine for a bit, but now it flickers and I have not been able remedy the problem. I have reset the UI a couple of times, changed batteries, all to no avail. Will dig into the light tomorrow and see if I can figure out whats going on.

Both packaging & light arrived in good order.
Light is clean & pristine eternally.
Slight oily residue w/ miroscopic Al dust deep in battery tube. Nothing to be concerned about but I did wipe it out.
Remainder of light clean internally.
Fit & Finish is excellent, both internally & externally.
Nice threads… very smooth.
Tailcap O-ring needed a bit of grease.
Firm double springs.
Driver screws snug & secure.
Reflector looks good, lens is clean.
LED’s appear well centered.
Q8 lights up & appears to be functioning properly after about 3 hours indoor run time at varying power levels.
Lighted switch seems to be working properly at this point.
Timed stepdown was at about 178 seconds.
Temp was about 55 C at stepdown (measured by IR temp gun)
Beam is nice & smooth. Nice tint.
All LED’s appear to be same brightness.
4 x 30Q buttontop 18650 batteries used.
My impression…… Very nice & well done light.
A big thank you to the Q8 team, M4DM4X**, TF, BG, & anyone else who had a part in making this light possible.
Well done!!!
In addition… Tracking was 100% accurate & worked flawlessly. It is highly recommended if you want to know where your package is after it shows shipped on the Banggood site. Do not be concerned if you package just ‘sits’ somewhere for a day or three…… that is just part of it. Nothing to worry about… it will get to you.
If you do not care where your package is…. please ignore the previous statements about Tracking.
Q8 #2 & Q8 #3 are scheduled for delivery tomorrow…. 9-20-2017
See ya’ then.
I think that about covers it.
Carry on………

NOTE / Just noticed, 1 switch LED is much brighter than other.
Ohh, ok. Understand much better now. Sorry, I call that the "Locator LED" feature, but I call the swithch LED an Indicator LED.
So, the "Indicator LED" can function as a Locator LED, but has other functionality as well. Why I call it an "Indicator LED" and not a "Switch LED", is because of other lights, not the Q8, than can have the Indicator LED in a different position, not behind the switch cover. Ok - for the Q8 here, I really should have called it the "Switch LED" -- would have been easier to explain and understand... 
Anyways, why you can can reproduce it so easily at 1/3 brightness or higher, is because the Indicator LED is blinking 2 times on high amps, and only blinks once at low amps, so, it's easier to catch it while it blinks.
A better way to get it consistently go off is as follows:
- from OFF, press&hold the switch til the main LED goes on (very low) and/or the switch LED, then release the switch and click it immediately. Works every time for me, unless I'm too slow..
Now I'm turning 60 soon, but still have fairly quick hands, so maybe that's why it's easy to me (pitched a lot of slow pitch against steroid injecting gym rats, and if you have slow hands, you will be D-E-A-D, dead!). I was just darn lucky on my team I had a few of those roid raging gym rats too and they would defend me if those crazies started hitting their rockets up the middle... "But it's just a game", yea, right. 
Ohh - my daughter played Big East Div1 soccer as a goalkeeper. Guess what made her so good at stopping goals? Quick hands, of course!

Entertaining read! But if you’ll allow me to try to boil it down, are you saying you have to hit the switch while it’s blinking to get it to disable locator?
Edited to shorten
I also received mine today. Everything looks and works great. The knurling is my favourite feature and that reflector is top notch.
I want to say great job to everyone involved! I'm very happy with how this turned out.
I stuffed in some very well used Panasonic 2900mAh laptop pulls that were all around 4.05volts and stuck it in the BLF legendary integrating sphere with the TA ND filter mod and got 4704 4744 lumens... Excellent!
Srs2000’s bong for your buck cracked me up.
Glad to hear that people around here are getting their lights. Mine should be here Friday.
Yes - that was simple
It's actually a bug that could be interpreted as a feature, least that's what we call bugs anyway. Bugs is a 4 letter word and feature sounds so much better.
I lol’d too
@ srs2000
Well done sir :laughing:
Got mine today, too. Shipped via free air express to California. Using 30Qs from mtnelectronics. Both green LEDs appear to have similar brightnesses, and have been working thus far (7+ hours). Fingers crossed.
As for the always-on beacon, is the Q8 really consuming only 135uA with the LEDs on? That's pretty good considering how bright they are.
I still have another coupon, and so I guess I'll order another one. Maybe I'll get it by the holidays. :-)
On these lights, there is a spring pcb screwed down in the tail, removing the tail cap only shows you that…. right? So why the worry over rough threads on the tail cap… the one that isn’t removed in daily usage? Puzzles me, is all…

Maybe to be able to ‘smoothly’ access the secret mini instructions some will stash in there. 
Fixed that for you 
Cheers David
…. Nooooooooooo not me. Some might, but I will not be one of them. 
just got the light today with standard shipping
the ramping mode works great but the blinkies not i double click from off to turbo then double click to strobe and if i click once again its off iff i make a fast double click i get to bike strobe but from there i cant get any further blinkies single click turns the light off and double click also off …. and the double click has to be very fast
Great seeing a lot of new arrivals that bring a lot of “bong for the buck”
Li ion and bang are a poor combination
After the one yesterday that was a setting thing we now see the 4th issue 
Can you make a video while it still is in flicker mode and has not stopped completely (yet)?
And pitches help of course.
Maybe some testing with a DMM?
Thanks for letting know and still be able to enjoy the rest of the Q8!
