Thanks MtnDon, seems my numbers perfectly match up with yours.
I expected entirely bypassing the tail pcb and going straight from springs to battery tube would be better than going through the contacts from the PCB to the tube. Guess not, but since it works just fine, I’ll leave it as is.
Nice to see good reports.
Some issues are being talked to via PM, will update the OP with the issues later.
Oh gosh, when the first issues popes up I suggested Barry some sort of Q8 Cool Kit with AR coated or ultra clear glass, a metal colored switch retainer ring and switch assembly with different colors to choose from.
Didn’t hear back on it, but it seems we all got a AR coated lens
And as always some don’t like it, sigh. A quick Google search shoes me several hits how to remove AR coatings
I don’t think mine is AR coated. First batch. I will look closely when I go home.
It should not be.
They were saying the second batch looks like it might be AR coated.
I was about to write something about my blueish 2nd batch Q8 compared to my 1st batch Q8, but couldn’t provide any good pics to go with it.
As this came up now anyway, side by side there is a visible difference in color when light is on and wenn it is off (reflection on the lens).
Will try to get a pic of this next week.
I don’t seek out new threads very often, so I just found out Marshall from Going Gear passed away a couple weeks ago. :cry:
I watched quite a lot of his videos. He seemed like a great guy.
Yeah it is sad, but you probably meant to post it elsewhere…
Haven’t done whitewall hunting, just comparing outside to trees and then I didn’t see it, will check proto, gen 1 and gen 2 today.
No, that’s on purpose.
I wish someone had posted it to a big thread so I would have heard sooner, rather than weeks later.
I put a link so folks can go there to talk about it and to keep this thread on topic.
Ah, yes it was posted and I think there was a topic about Olight doing a special day to help out.
I don’t think anyone got a Q8 with AR coated lens
When you point another flashlight to the lens of the Q8 with an angle of about 45 degrees you can see 2 reflections (each on one side of the Q8 lens):
1st batch Q8:
2nd batch Q8:
Do you see the difference? Looks coated on one side of the lens.
nice pics Mike!
My 2nd batch example…
No bout a doubt it, AR coated…
Does everything work as it should on the Q8 after a spring bypass? Is there any other reason flashlight manufact. dont do this on stock lights, besides the fact that it adds cost?
Is it a safety issue of some kind?
Also, is AR-coating a good or bad thing?
Just asked because my second batch Q8 has regular lens 
Thanks
Probably, yes. If it has a USB port, it can probably be used for firmware flashing.
We should stick to Narsil in this thread though, and go to other threads for other firmware options. Otherwise it’ll get confusing pretty fast.
I’m happy that the hardware can do off/low/high on the indicator LED though. Given how easy the Q8 is to reflash, it might be a nice mod option for people who want the switch to be less bright. It’s a very small patch, potentially just one line.
I just ordered a 4th one with the affiliate link and code originally sent with the PM, both are still working. 
Think I posted a few times - I modded a batch of Q8's getting 7,000 to 7,200 lumens at turn on, stock Q8 LED's, batch #1 lights but with all the tweaks, but still used the stock 18 AWG wires. Some suspected our readings, some didn't post their readings thinking they were not correct. Turns out others ended up getting the same #'s once they got their lights and modded them, so now, it's been confirmed many, many times.
My best modded Q8, so far, is 7,340 @start, 6,720 @30 secs, and that's with 70 mm 16 AWG wires and the SIR404DP FET, plus all the usual tweaks, and it's a batch #1 light.

I measured 7,112 (IIRC) at startup on a first batch light.
