Both of mine arrived today; they were ordered within minutes of each other the first day they went on sale.

One is perfect so far.  The other has a couple issues we've seen, and (I believe) a bran-fresh one (lucky me Wink ).

 

First issue is asymmetrical LEDs in the switch.  Here's a pic of both, and while it's not a great picture it shows a smaller bright spot on the right side of the right light's switch:

 

The second issue can be seen in this picture.  There's an obvious flaw in the tube/anodizing.  This came out of an absolutely unscathed box, so I don't believe it occurred in shipping:

 

Here's a close up; not sure what caused it tbh but it's not a simple dent.

 

 

Interestingly, the light with the flaws pictured above also has a battery tube that's not correctly aligned with the head when fully tight.

Mine arrived and it’s perfect, no problems to report, everything works fine, it’s heavier than I expected, thank you so much Q8 team! Party Beer

Will update on this thread if something comes up…

Frustration is understandable given the anticipation of this exciting light. Maybe I’m a persimist, but I recognize the monumental task of getting a complicated piece of electronics manufactured half-way around the world. The barriers are enormous. It seems to me that off the shelf, stock flashlights have a higher than average failure rate compared to other commodities.
In fact, I buy most of my lights from modders like Vinh Nguyen, not just because they are bright, but any problems have been fixed in the upgrade process. Not to mention, I’m dealing with someone I consider a friend and warranty work is a fast, state-side turnaround.
So, why go for this given my pessimism? Because this is a great flashlight design, backed by a hard-working team who did their best. And let’s be honest, where pray tell can you find a better bang for the buck in a flashlight. Wasn’t it worth taking a chance? And the outcome seemingly has only one insignificant glitch, which has nothing to do with the reason we bought it.
This post is to say thanks to the team!!!

Thanks for mentioning tube alignment ‘feralcomprehension’. Thumbs Up
I gotta go back & check that. Nothing jumped right out at me…. but never can tell, I was paying attention to other stuff. Wink

I/we … deserve to know a solid date for production to resume. Not a guess, not a “whenever” but a definite time.

Instead of shaking your fist at the empty sky demanding to know when it will rain again, this might be a good time to do something else. Go for a walk, talk to a friend, laugh at cat videos, rock out to loud music, argue with trolls on 4chan, do some cleaning, whatever works for you. A delayed flashlight isn’t worth raising one’s blood pressure.

I’m anxious too, with a project or two waiting on a Q8 hardware, but there are plenty of other things to do in the meantime.

You’re right about it being a toy. It makes people complain exactly like my 5 year old on a bad day.

I’m not sure why people are expecting the tubes to be aligned ? Do you expect them to be individually indexed, or selectively fitted, or so precisely machined that every one is perfect, and interchangeable ? Do you know of any SRK type design which does so (certainly not the classic SRKs.)

It is a feature of the design. Even if somehow all the above was done, after a bit of use and wear, the indexing would shift anyway.

The alternative is I suppose a bland cylindrical tube.

drive it at the lowest current level that is fully characterised (much brighter), then PWM it down to the desired level.

Not an option. With the MCU doing PWM, it would be about 0.1mA for the indicator LED and about 5mA for the MCU. It can’t do PWM while it’s asleep, so it would drop the efficiency and standby time to about 1/40th of what it is now. It would be pretty much the same as leaving the light on in moon mode all the time.

Edit: I did find a potentially-relevant trick on my old Ferrero Rocher light though. I was able to get three brightness levels (high, low, off) from an indicator LED in sleep mode by messing with the pin mode. High and off were fully within spec, but for “low” mode I had to go off the data sheet and do things the MCU didn’t really support. I suspect it might not work on a Q8 though, because it probably relied on the voltage divider resistors which newer drivers don’t have any more.

Better they stop production and figure out the issue and change whatever needs changing than them continue putting out hit or miss products. As for a definite time that is impossible to guess at until the solution is decided upon, parts if necessary ontained, etc.etc.

Received mine yesterday.  Real fine light.  Looks and feels great.  My wife digs it too.  I immediately bypassed the springs and drilled the driver mounting holes to clear the mounting screw holes.  Neither were necessary, just my preference.  The light is the real deal.  I measured 6K lumens in partially depleted 30Q's.  The light get hot fast like it should.  Beam pattern is a great mix of flood and throw.

This is my first time using Narsil.  Love the ramping and natural feel of it.  I got lost a couple times in the UI, but that is probably just operator error.  The indicator light is very bright for my taste (Think I will swap in a less harsh red or amber emitter).  The indicator emitters turns off when the light it on.  Is that by design?

Very happy with the light and I totally understand the frustration of those awaiting to receive theirs.  Big congrats to The Miller and team.  First light I don't feel the need to do any major mods on.  Hang in there guys.

My take on battery tube alignment is that mine spends the vast majority of time “aligned”,

… during the daylight hours,

… where it can actually be seen and appreciated.

I thought that was a brilliant design decision, thanks Team Q8!

I never even noticed the tube was “misaligned“when fully seated. I did not expect it to and don’t care if it does not.

> production stoppage

Don’t get bent out of shape.
Consider the odds are that they did stop production for good reason.

Like, they need to understand why the problem is happening and, importantly, figure out whether it would appear over time with more flashlights.
You don’t want them to rush and ship you something that is going to make you unhappy later on.

They are smart to be concerned not about just a one percent chance of disappointment but about the possibility of shipping a known failure or problem that will appear after a while.

Could be there’s a problem with construction technique. Find that guy and educate him.

Could be there’s a problem with a bad parts lot.
Could be all the good source parts have already shipped and the next batch to be built would all or mostly have (or develop) the problem.
Are there bad parts in the bin they’d be drawing from if they kept building lights? They need to find that out.

And remember — it’s several companies supplying parts, several people putting them together.
All you need is just one person on the critical path with the chabuduo — “hey close enough just ship it”— attitude, covering up a problem and passing it on.

Finding that person can be a real difficult task, as that person’s manager could have the same “close enough” problem and be helping hide it.

Could be they really care about their reputation for doing quality work. Signs are that’s what’s happening.

Maybe you would feel different if you didn’t already have a flashlight sitting in your lap

No, Joey, I’ve said all along — I want the manufacturer to test samples from the first run properly (that’s QC) and check during production for problems being built in (that’s QA). And I’m well aware of the “quality fade” issue that we’re all hoping to avoid with this production.

I’ve accepted that the first run of any batch is going to have undetected problems because we’re the QC/QA people for most of these manufacturers. That is, we’re the “Charlie test” group. There’s the alpha test (first round); there’s the beta test (did the first round get fixed?); and there’s ship it and “Sorry, Charlie” test group.

If the first round were proving to be good enough, they wouldn’t have stopped pushing them out. Four percent failure in the first 24 hours is one thing. But if that’s an early indicator of a problem that will emerge, that’s something else.

If they are concerned that the asymmetrical brightness is an early indicator that a light may develop the flicker-failure problem, they have good reason to pause.

Trust me on this. I own a Cometa. I’ve avoided a number of the other disaster-batch flashlights that have been popular here.

Talk to anyone who bought one of the bad ones. Ya think they feel different — happier — because they got them early?

Don’t think so.

But the fact that these four lights are showing very similar problems leads me to believe that it’s much more than a coincidence and it bears looking into.

I’ll keep patiently waiting.

Posted this as an edit to my original post…but wanted to put it here in case it was helpful or relevant to anyone.

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.

THANKS AGAIN Q8 team!
And thanks TomE for encouraging me to play with the switch thing some more. Thumbs Up

Are you talking about the tube screws in the head a bit “cockeyed” OR… the flats on the tube are ‘mis aligned’ with the head??

A little time with a piece of sandpaper on a nice thick piece of mill finish steel can quickly adjust this. I use a worn coarse corundum belt then 400 grit wet or dry on a piece of 3/16” a2. Stand the tube on the paper covered steel and sand while maintaining the angle. Take a few passes while gradually turning the tube to evenly sand the un-anodized end and test assembly and repeat as necessary. When close to aligned repeat with fine paper to smooth the end and do final adjustment. It’s the method I used to align two tubes to the head assembly on my Chimera. Of course, alteration like this would void the warranty.

Hank I was responding to your flippant “don’t get bent out of shape” comment. I just feel that maybe you should off commenting to members who have now coughed up multiples of 40$ for a flashlight that we now have no idea when it will be produced. Each issue during development led to a month or more each time. Sorry but I would take one with asymmetrical indicator leds over an open ended whenever any day. And most of the other 1600 would too. I am going to wait but I don’t need a lecture on quality control. In fact it seems a few post up that one of the problem q8s now seem fine. I will abide my time as will most other members.

What part of Florida? I’m in contact with someone from high school in Ft Myers and my younger brother in Tampa (busy with construction work doing repairs). Ft Myers got hit hard whereas much of Tampa had power within 48 hours.

Dunno why, but ThorFire has been in a big rush to get these going as of late. I have no doubt it's gonna move quick. Last word from TF was they seem to know what's going on. Not sure I posted these, but these pics were sent to TF:

Last Prototype (round 3):                   Production: 

    

Clearly they changed the LED's - gold tracing to silver tracing is one sure sign, also a different layout of the traces. The resistors are the same value, 15K, which I recommended from the round #2 prototype after experimenting with them. The prototypes are definitely not as bright. Round #1 had only one LED, so was a different PCB.

That is a perfect description….. that is exactly how one of mine looks also. Good job putting it into words. Smile

I was watching the nhc site and others for days before it turned north and following the movement of pressure systems and spaghetti as Irma moved. I know you saw some rough conditions but were fortunate as were millions of others that early forecasts predicting a direct path through Miami as a Category 5 were wrong and Irma lost a good bit of power following the coast of Cuba. I’m not minimizing the severity, just thankful it wasn’t worse.

After using it heavily for over 1 hour, maybe 30% of the time on max, and then max for 3 min, temp was only 42 Cel in 2 Cel ambient temp. I will not care if the switch Led stops shining, it isn’t that important, will possible disable that Led. Walking in the dark forest with this flashlight gives me complete peace of mind.

Had no switch problem. I will enable Thermal Temperature stepdown and want the switch light to be permanently on to easier locate it in the dark, except when in lock mode.
