Q8, PMS SEND TO THOSE WITH ISSUES BLF soda can light

Hearing that your 3rd one is DOA is real comforting, considering some of us would settle for a single unit that maybe had a off bright switch led.
Waited a year + for squat. On a list that means squat.
And What happened to the order list near the top of the OP??
Pffffffff, vanished. Funny how that happens.
Disgusted.

My thought was two workers were tasked with placing the emitters and working from two different spools. It seems possible to me but I could be wrong but the best possibility of balanced output is sequential emitters from the spool followed by testing with a calibrated voltage/current source. In a mass test groups could be wired to power in a manner that split voltage and current and uses photos to isolate extreme variation between emitter pairs. When doing calibrations I sometimes did ‘gang’ cal of groups of low accuracy (±3% or +) voltmeters where the combined uncertainty was less than the certified accuracy of the standard. Not endorced procedure but after testing groups of meters and following up with individual tests not one failed. A superior kind of freaked out seeing me do it but every meter I passed was within tolerance when re-checked.

Thanks tekwyzrd.
Hurray for BOINC, by the way.

So with 2 LEDs in parallel, the risk over time down the line would be if one of them dies or its connection
fails, all the current goes through the other one and fries that one? That would explain a cautious approach.

Who are you referring to?
What do you mean by doa? The switch led or the flashlight?

Nah, if one burned out it would be like a 7.5k resistor on the other led. It would be a bit brighter, but not burn out. I think Amplificus shorted the resistor and the leds did not blow. They just drew way too much power so the battery drain is much higher.

Or you could just be me

Switch leds measure 2.246v each with batteries at 4.008v. In case it matters.

It’s been many years since I did this, but I have had luck in the past using two irons - one in each hand, with the tips on each pad. Use the tips of the irons like tweezers or pliers by pushing them each towards the other and lift the part off the board.

I’ve been playing with the UI and have a question since you asked JasonWW.

I am back in ramping mode, and have configured Moon mode for the lowest level.
Click and hold starts the light from a low and ramps up - as expected.
Ramping it back down, I get a switch blink at a fairly low level. - as expected.
I can select a level, turn the light off and with a single click I get the remembered mode. - as expected.
However - from off, with a medium click - I get this crazy dim moonlight level (I like it - it just does not seem to be in the cheat sheet or the doc on post 2.) This seems to be the only way to get into this level. I can’t ramp to it at all.
My eyes are a little whacked right now - mostly from the Q8, but also staring at a monitor. So I’m going to go sit in a very dark room for a while and see what this level looks like.
I’m just wondering if this is a know feature or an easter egg?

Just want to pass it along that ThorFire is sorry for the delay, and they think they can work out the SW LED issue quickly. Don't know, or am sure, of all the details, but sounds like they will go with a 2 resistor design, and go back to the LED's they used on the prototypes. They are also looking at some of the screw issues - no promises there though.

I was actually about to comment on that Lazy-R-us. So what is happening is that via ramping down the lowest level is ALWAYS the “default” level. The only way to get to the user specified level 1-7 is to hold from off and it turns on in that mode, then you let go immediately. Also something that bugged me… I set the moonlight level to 7 because I dislike moonlight and always ramp up for a moment before using my lights, but if you long press to get my default value of 7, then keep holding in, the ramping dips back down to the default of 3 before ramping up. Essentially ramping doesn’t reference the user specified moonlight level as where to start ramping and always starts at 3.

The screw issues barely bother me, but I’m glad Thorfire is working expediently to get things shipping out again. There is light glue on the tail cap spring board but it wasn’t like a loctite, just kind of sticky. It was also between the board and where it contacts the body tube. I cleaned it off on mine, but it wasn’t an issue, just something I noticed while being nosy. All of my screws are in good shape.

I was expecting this light to get hot, but even after 8 minutes of turbo it’s barely breaking a sweat. I really like that, turbo is a practical mode.

Found one list, now saved for prosperity,

No, there shouldn't be a danger of either one burning out. The current is just too tiny for that to happen. The issue is that one or both just won't work (or will work intermittently). The rest of the Q8 should be perfectly functional.

Yep, a little of both. Not sure why I didn't change/fix that before the release - I thought I found this early on and knew bout it. It might have been too late, not sure. So, if you set moon mode, only way to access it is press&hold from OFF. Can't ramp down to it. Not sure where now, but I know I fixed this - might be in the next version, might be in the D4 version maybe, not sure - I know I had ramping work to go down to moon mode at some point..

It kind of got orphaned - can't ramp down to it, can't save it as the "remembered" level, but, if you start ramping from OFF, it's always there first thing,and ramping pauses on moon mode so you can catch it easier.

DOA, dead on arrival.
Sorry, should have quoted but didn’t want to single out any particular member, doesn’t really matter, just having people comparing their 3rd light received not working properly while others have none, though ordered and paid for on the same day just pours salt in the wound.
These codes could have been handed out in an orderly manner and/or limits on purchases made.
If you need the post # it is 13250, again nothing against that member.

TK, I use the beacon on the H17F on the lowest output setting for night stand duty. Only on lights without trits. I love the beacon mode on it!

Replaced the resistor on the faulty switch board with 10K and the LED is working fine at 0.155 mA. I’m thinking that for some combinations of high Vf LED’s and high-side of tolerance resistors it’s just not giving enough voltage to be stable.

I ordered 3 x Q8”s within minutes of the code being released & all 3 in the first 200 orders :slight_smile:
1 was to a delivery address in the USA & 2 to my address in the UK.
The USA one arrived yesterday & appears to be fine :+1:
My 2 however have been showing this tracking information for the last 10 days “2017-09-11 03:33
Arrived In Hongkong, Waiting To Fly Away”
I am just wondering (I guess I know the answer) if my 2 will “fly away” to me as they are or is there any chance that Thorfire can/will recall them to fix the lighted switch issue then re-ship them ?
I guess as they are in Hong Kong, according to the tracking information, that they will just continue on to me eventually as they are ?

Just to be clear it was the 2nd light “I” ordered, the 3rd one was a gift to me from someone. That was covered HERE

Nor did I post to brag about receiving Q8’s… I posted because we were asked to.

I have not ordered all I am on the list for ‘yet’. I did order the three I am giving away, .
I have not ordered one for myself yet… as I knew I was being gifted one.
I will however order it before the coupon code expires.

I understand you are upset & I am sorry…. but I had no control over how anything was done or handled. Nor the rest of the things you mention either.

Hopefully things will progress quickly.

This is dedicated to applying some ’mojo’ to your UK order’s that they will “FLY AWAY” to wherever is most benificial to you Sir Ian…. :wink:
.

Same here. I got the message “Waiting to fly away” a few days after the “shipped” message, far before any light reached its destination and the switch led issue became known. Same message up to now.
I dug further into this and realized the site “dpdgroup.hk” (where 17track and other tracking sites get the information about this carriers tracking) has moved to a “domain parking” service about a week ago. For a while 17track displayed a notice telling their tracking information is only a cached one. This notice is currently not displayed but since “dpdgroup.hk” is still not in order I’m pretty sure the tracking information is still the cached one.

I can’t track my ordered lights anywhere else - neither international nor local - and am curious if they are still on there way to my place - or lost.
