Always annoying to receive batteries with wrapper defects although since this is an unprotected battery it’s relatively easy to fix the wrapper yourself if you don’t want to deal with having BG replace it. Since the wrapper is too heavy on the negative side, it’s easy to remove it – just snip (perpendicular cut) a part of the excess so that you can peel the rest off with your fingers then put on a new wrapper and just use a hair dryer. If you don’t already have spare wrapper it’s only around $1 shipped from China for a small roll but you’ll have to wait a couple weeks to get it.

Thanks to both of you.

Honestly, I am not impressed by whatever company added these extra tops. It has a flimsy piece of metal between the battery and button top.

I guess it works okay, but is probably why Tom E’s test showed the solder top versions out performing the button top. I may just remove the button tops and add some solder blobs.

EDIT 2: 9/20/17
It appears after playing some more, that my switch just MAY work like it’s supposed to in regards to disabling the switch LED when the light is off (after reading TomE’s suggestion of how to hit it). It does appear you don’t have as long to click the switch a second time when the light is in the lower voltage outputs…and that timing is a little more finicky…for me at least…than when the light is in brighter modes. SO….mine may NOT be an issue…JUST FYI. ALSO, I just left the switch LED on for the past 3 hours or so and after coming back to the light, it did NOT appear to be flickering or anything.

POSSIBLE ISSUE (wondering if others with LED beacon issues might have the same problem and just didn’t go as far as I did in “playing” with it…doubtful…but wondering)

Got my Q8 yesterday. Gonna state the issue first..then brag on the light.
Beacon LED function – I’ve tested this dozens of times and this seems to be the behavior mine exhibits. The beacon comes on after turning off the light regularly and dependably (the best I can tell). The erratic behavior comes when I want to turn off/disable the beacon. I noticed sometimes I can get it to go off and sometimes I can’t (with the switch click right after turning on). I have narrowed it down to this: I can get the LED beacon to disable IF and ONLY IF the light was turned off at about 1/3 to 1/2 FULL level or brighter. If I turn the light off in any mode lower than that, the LED beacon will NOT turn off. If the beacon won’t turn off, all I have to do is turn the light back on, turn the brightness up to at least 1/3 to 1/2 FULL brightness (I’m eyeballing, no meters to gauge)turn it off, then do the quick on and off method, and BAM…..the beacon disables….EVERY TIME. No matter what brightness below that level I try to turn it off at, it will NOT let me disable the beacon….until I raise the brightness first.

Let me know if more info will be helpful. I tried to describe it as clearly as I could…but I’m sure it came across jumbled.

Other than that…perfect operation, thing is a TANK, love the feel and was very pleasantly surprised how “small” it is…I was expecting bigger.

THANKS TO ALL WHO HELPED!!! Been watching this since almost inception…never thought I’d have the patience to wait for it. My first SRK style light…and probably my last…as it’ll be hard to top! Smile

Try this for dependable disabling of the LED: Ramp down to moon mode and turn off immediately.

Beacon led as in the switch indicator. The side switch has a beacon function, correct?

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.

Q8 #1

Ordered 9-7-2017
“Shipped” 9-8-2017
Arrived 9-19-2017 _ Gadsden, Alabama USA
Free Shipping _ FedEx SmartPost
No Insurance added

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 × 30Q buttontop 18650 batteries used.

My impression….. Very nice & well done light.

A big thank you to the Q8 team, M4DM4X_(Martin)_, 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………
…………………………
Edit to add…

  • Free Shipping FedEx SmartPost / No Insurance added
  • Reflector looks good, lens is clean.
  • LED’s appear well centered.


NOTE / Just noticed, 1 switch LED is much brighter than other.

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.

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... embarassed

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. smile 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?

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!

Yes - that was simple smile

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.

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.  Smile

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…

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

After the one yesterday that was a setting thing we now see the 4th issue Sad
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!

Title changed and OP updated with an announcement;

Dear all,

It is clear there is an issue with some lighted switches.
I have a little sad announcement to make, production of new Q8 lights is halted while the problem is solved.

There are 2000 hosts ready for assembly and all the parts needed are there.

Thorfire is contacting the supplier of the SMD LEDs and all pictures and tests people do with a non working lighted switch assembly help to further pinpoint the reason of failure.

So I am very sorry to say we are back at “it is done when it is done” but with a big difference, before we did not have a problem if answers took days or even weeks, now that everybody has literally invested at least $40,- we want things to go fast and Thorfire is very responsive so there is good cooperation to get it done ASAP.

This also means that if you have not received a shipping notice, it will not come before it has been made clear the problems are solved.

I have confidence in Thorfire, the issues (now 4) came after some use, all Q8 lights work out of the box so that is great.
With 4 problems more are expected so this is the best way to proceed IMHO.
I am really sorry that the wait continues and hope you can accept it.

Also keep problem reports coming, we will find a good solution while aiming at having the rest free of the issue.

FIXED SWITCH LED!

Turns out it is the resistor. After swapping to another smd led i had from a battery back circuit board (getting polarity right on those things is a pain in the arse), it was still flickering. I re-applied heat to the resistor and noticed that when the iron jumped the resistor (touched both sides) both switch leds came on really bright. So i stacked another smd resistor on top of the original and BAM! Solid light. Measured current draw 6.6mA so you do the math on what the equivalent resistance is, I’m too tired and can go to sleep happy that we found a fix.

Your welcome Big Smile

How do you disassemble the switch? I got the 2 screws out from the driver board but then the wires are fairly short to really see anything else. I’m hoping someone can do a detailed breakdown of the flashlight for modding. I’d like to swap out the green LEDs for something different. Perhaps pink and blue?

Once you can get past that first blinky, into the 2ND or higher, you press and hold to go back a level and can then click to go forward again if you wish. See my video. I think it’s Narsil Part 2.
