I agree not to change it
Think of it this way it’ll be our own nerdy secret
It could be what could make the first run with the misspelling a collectors item in years to come!!
That soldering job on the driver lol make me look pro 
I’m thinking you are correct. Check out the pic FmC posted above. 
You just need to look at it in the mirror…
(Or flip it over and look at it from the other side. )
Just now had a few minutes with the prototype: as Tom already mentioned, on solder blobbed 30Q’s, @30 seconds, I measured 5600 (djozz-) lumen. Strange enough, on my solder-blobbed VTC6 cells I get less, 5400 lm.
I did a 3 minute runtime test on the 3Q’s, and found that just before the default 3 minute stepdown, the output was still 4700 lm (so still well above the initial 4000lm goal of the Q8 project), and head temperature as measured with an infrared thermometer aimed at the fins was then 54 degC (which temperature is considered to be about the human pain level, I can confirm that :party: ). After the stepdown I measured 1450lm and the head temperature levelled out at 44 degC, d*rn hot but bearable.
So at room temperature without air flow, the default 3 minute stepdown to 1450lm is about perfect for me, no need to set a custom stepdown temperature.
Nice input there Jos, the heat levels are set by default at just about perfect levels, output is excellent, and of course, we still want pictures so we know you’re not making all this up. 
Shine it in a cops face in Turbo while you take a picture, that’d be cool.
You may want to have a look at this app:
It seems pretty good at logging and charting anything your phone can sense.
It was mentioned already, but zakwilson’s “ceilingbounce” app is designed for this.
man, it’s not easy.
Kennedy said something about that when he announced that America was going to the moon :party:
Great to see you here Barry, it certainly is not easy but we’re all doing our best and I think a good job is being done!
I thought Barry meant the app was not easy to use.
Doing great Barry!
4 of 7 samples in
I can confirm on mine that
The outside is as designed and planned
Nice addition of CE ROHS “don’t toss in bin” marking (the CE logo needs a little more space between the C and E)
Lovely to look at the depth of the fins and see them get deeper near the LEDs
Tripod mount works fine , even with a huge tripod plate.
Threads are very smooth, there was no grease, and that gave me the opportunity to feel how smooth the threads are, very nice.
Switch is precise and good.
Driver bottom looks very nice, with “Q8” - plastic ring - nice brass ring - plastic ring with space for screws in outer ring
Elegant and the Q8 vias line up beautiful.
This is great for even things not looked at normally are done so nice!
I haven’t taken it apart yet, first gonna test the modegroup settings in Narsil
On four protected Panasonic low drain cells it already has an impressive output
It already is brighter then the Nitecore TM06S , Convoy L6 and Thorfire S70 and S70S that were my brightest lights before yesterday
If course the XHP70 lights with big reflector throw further but the area the Q8 lights up is awesome.
The tint is pleasant without annoying shifts to green or blue
It handles heat fine but will have to rely on others testing with higher drain cells
The LEDs are not 100% aligned but this is not a big deal, even on the $100-$150 Nitecore TM06S the LEDs are not 100% aligned and on both Q8 as TM06S the beam does not suffer from it, it is so little and by how the quad reflector and quad LEDs work it does not show even when whitewall hunting.
Narsil is amazing
And Tjirfires side switch works very good with it.
Ramping and let go makes the side switch blink and tell if the 7135 only or also the FET is used on the level chosen. 7135 only is remarkable bright, much brighter then I expected from reading the numbers
Quick access to voltage check is useful and nice
So much can be setup, amazing, from moon level, how side switch behaves, thermal/timed stepdown to blinkies
There is a bug in Narsil so Tom has to do some code writing and for production the updated Narsil must be used.
There were no spare o rings in the box and the simple manual as provided was not there.
Maybe add a switch cover too?
Other then this and pending teardown and measuring I say with the following things to be done:
1 updated Narsil
2 CE marking little more space between C and E
3 spare o rings in box
4 manual in box
I can give the GO on the Q8
So there Barry, 1 out of 7, let’s see what the others have to say
My copy of prototype #3 looks and behaves exactly like Miller’s and Tom’s it seems, so I agree on Miller’s observations. These prototypes are consistently good.
About the Narsil UI that I have not used before: I have just played with the default ramping UI. The ramping is fast, very precise, and intuitive, I have not for a moment wanted to discover the other UI options.
It is very well thought out that from off a ‘click’ gets you on the memorised output setting, while from off a ‘hold’ starts ramping up from the lowest level. In practise that is really intuitive.
The ramping is fast enough that for maximum brightness I simply ramp up, I do not feel the need for a short-cut to max.
yeah, it also feels great to see it get brighter and brighter, much more fun then double click and have it on turbo right away
MARK list updated
Thanks man!
That golden Q8 inside that golden ring is a very nice touch! :+1:
yeah agree, it is cool to have nice details even in places not normally looked at
Drumroll please!! The tension is mounting and across the world flashaholics are starting to feel their blood pressure rise… so close so close we are about to witness an historic event in the flashlight world!
heheh
