Q8, PRODUCTION HALTED PLEASE READ TOP OP, the Q8 BLF premium edition SRK type monster flashlight
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.
 
 
.
.

First real Q8 flashlights arriving.

FIRST

IMPORTANT: DO NO EMAIL BANGGOOD CUSTOMER SUPPORT ABOUT SHIPPING< YOU WILL GET A BASIC RESPONSE THAT DOES NOT HELP YOU AT ALL. SUBMIT YOUR QUESTION IN THIS THREAD WRITING Question for Banggood above it (IN BOLD so I can easy spot it even when with a lot of new posts.  

Collected questions:

When are we going to see stock again?

What happens with expedited shipping, paid for but not arriving sooner? (WE NEED A PIC OF SHIPPING LABEL WHEN IT ARRIVES TO BE ABLE TO WORK ON THIS! NO PIC OF LABEL PMMED WE CANT DO ANYTHING!) Answer pending, awaiting arrival of these Q8 lights and pictures of shipping label

 

SECOND

Relax about shipping of your order, it will get there. the dates mentioned on Banggood do not say anything other then the absolute latest, when the pre orders started it was not clear that th first would be send out so fast yet shipping started the same day and while it was expected that now after a week the shipping would commence, some already have their Q8 in hand. read FIRST again and please "order and forget" is much better for ones stress levelsthat constantly checking shipping status. JUST DONT DO IT! 

Tracking is buggy at best, there is a long chain between you and your light, delays are possible at each link of that chain.

 

THIRD

Issues, please post your issues, or things you think that might be an issue. It will be added.

keep it at REAL LIFE EXPERIENCE ISSUES,what you THINK that COULD be an issue is very good to remember for yourself, no need to post about it.  

REAL ISSUES FOUND

 

BEACON LED IN SWITCH

Beacon functionality of switch, erratic flickering instead of constant lighted switch (first use working good)

Beacon functionality of switch, no light from switch (first use working good)

 

amplificus started flickering after some time in use, confirmed issue video https://youtu.be/GSdDHodWk2U

saypat stopped working after an hour (please video?)

engber switch led issue, first run OK, then flickering started, now no more beacon at all (please video?)

tru3s1lv3r  intermittent switch light, after working OK first time.

nishayume no switch light

teacher DOA, solution, DO NOT OPEN OR TRY TO FIX, swap with a good Q8 of Tom, so Tom can investigate and report back in depth. Tom is a true "professional guy" Wink

 

Perceived issues NOT CONFIRMED

SCREWS:

Screws. really not an issue, they do their job, are lower then the brass ring of the driver. One might want to change them, please discuss in Q8 modding topic http://budgetlightforum.com/node/55026

Please stop talking about the screws in this topic unless there is a real issue in YOUR light with them.

Some tips on the screws, they are tight, use a properly fitting screwdriver and to be sure a rubber band to make the screwdriver fit even better while removing them.

 

 Use protected button top cells for a bit extra safety, below are cells that give max output but do not have protection!

Use matched "married" cells and check for equal wear regularly!

WHAT CELLS TO USE?

OK the SRK is a light that comes up very often, and well when it comes up there always are people saying how poorly they are made nowadays.
Sky Ray King, a soda can flashlight. Once constructed solid, now cloned and made cheaper and cheaper. The good cooling properties are long gone and many have fake LatticeBright LEDs on a thin aluminium board driven by a poor quality thin wired driver.

So lets force out a good one like they used to be, but with modern features.

…..The 47K and 220K resistors are the voltage divider, where the 220K is R1, the 47K is R2
…..The 12K resistor is a FET gate resistor (on the trace from the MCU I/O pin to the FTE Gate,
……connected to ground.)
…..Diode is for reverse polarity protection
…..The SIR800DP FET is expensive, but can easily handle the high amps we get in driving 4 parallel LED’s but too hard to get hence FET now in place and asked about.
…….from 4 parallel cells, without any degradation or heat. It’s an extraordinary performing FET for it’s size

Change list from original OP design ideas:
Integrated LED shelf instead of screw in copper/brass
Lockout via side switch instead of adding a new to b designed tail switch
Added low voltage cut off
Added AR coated lens
Removed AR coated lens because of tint shift.
Added DTP to stars.
Removed Quality lanyard
Added Cree XPL HI as possible LEDs
Added Nut to attach tripod negotiable
Added charging system like BD0x negotiable
12 April Refreshed specs and features, easier to read, corrected some spelling errors
Changed bezel to black bezel
Added Reflector height, diameter and support rim as the current SRK reflectors
Added Head internals support rim of the reflector
This ensures compability with the SRK reflectors so owners can mod the Q8 to use from 3 up to 10 emitters with a SRK reflector that is widely avalable.
Added Parallel max 4 cell configuration (to use 1, 2, 3 and/or 4 cells)
Added Able to take the largest of protected button top 18650 cells
Changed spring configuration to Double springs with the smaller being a Phosphor Bronze spring
Added 18 AWG Wires
Changed wires to 20 AWG, thik enough and easier to adapt reflector base and installation
Added Wires to led not through center of integrated shelf but the sides of it
Changed specslist to look more like a spreadsheet, hopefully this reads easier
Changed 20 AWG wires instead of 18, this should be thick enough
Added Light comes with spare o-rings in all the sizes used.
Changed drops from 2 meter to 1 meter
Added about droptest falling in different angles, the 8 corners, bottom and side hitting the ground first
Changed LEDs chosen emitter XPL Neutral white
Added Pilotdog68 driver design to team.
Added Thijsco CAD analist to team
changed 12K resistor to 47K
Removed Wires to led not through center of integrated shelf but the sides of it after wire specs, how wires run depending on DTP stars design (1 big LED board for all LEDs or 4 small stars for each LED 1 star)

BLF Q8
This flashlight is completely designed and developed by flashlight enthusiasts from around the world, gathered on the website BudgetLightForum.com
The result is a highly versatile flashlight.

It can be powered by one to four 18650 Lithium Ion batteries and is controlled by an easy to use electronic side switch.
The four high performance neutral white Cree XPL LEDs are mounted on a copper plate for maximum light output and reliability.

The custom built circuit board for the Q8 allows the light to operate from below 1 lumen firefly mode to a massive 4000+ lumens.

Very high frequency insures no audible or visible PWM.

The features in this one flashlight makes it suitable for a lot of situations a flashlight is needed for.
Photographers, campers, fisherman, cyclist and emergency workers can fit the Q8 to a tripod for hands free use.

BLF Q8
A classic soda/soup can flashlight design, re-engineered with more functionality, power and efficiency.
4000 lumen of flood and decent throw in a high quality, easy to use flashlight.
This flashlight lights up a large area to at least 150 meters away.

Cree XPL V6 3D Neutral White LEDs are known for their quality and durability. These offer a pleasant tint.
The custom DTP copper plate provides the best possible heat dissipation.

The BLF Q8 uses up to four 18650 batteries.
It works with just one battery with reduced output on the higher modes and with every battery added it can work longer and with two or more batteries used the brightest modes are fully functional.

It is operated with a side switch.

.

The software makes it very easy to use.
Every user can choose to configure how the BLF Q8 works:

moon/firefly, brightness from barely visible to very low

how many modes the light has
the order of the modes (from hi to low or low to high)

ramping instead of modes (smooth gliding between 150 brightness levels with a click and hold. The light stays in the desired brightness level when the switch is released.)

5 strobe and beacon blinking modes yes or no
to read out voltage of the batteries

The light is safe with features to prevent parasitic drain to avoid depleting the battery when not in use.

lock out of the switch, this prevents accidental turning the light on.

low battery voltage step down and cut off to prevent battery damage.

User configured Turbo timer step down to avoid heat issues.

When the switch is not locked out by user and is pressed for 20 seconds it will automatically lock out and turn the light off, to make sure it will not go on when put in a bag or pocket.

Opposite of the switch a 1/4” UNC thread can be used for mounting the Q8 to a tripod and hands free operation.

With its ease of operation, relative compact size and tripod mount the BLF Q8 is an ideal light to use:
During work in large and small spaces
As theater, photo and movie lighting
On the camping
When fishing or during other outdoor activities
To light up even the biggest rooms during power outage

BLF Q8, a high quality must have!
Color Black
Flashlight Modes Ramping or 12 mode groups to choose from

Nice initiative! But if the idea is going to be a new design by a manufacturer, I see a thousand good reasons to have a good conversation with kronological about it, to avoid the many pitfalls.

I like the idea of Thorfire making it more than a deal with Fasttech. I think I remember that attempts of group buys with discount never worked with Fasttech.

If it is designed from scratch, a version can be made with a 4mm shelf that is continuous with the body, and separate ledboards screwed on top of it, that would be very versatile, and good for the heat path! The driver could simply be the Kronos X5/X6 driver expanded to the SRK-size board. A (elegant) handle would be a great extra!

Nice idea.

Wouldn’t it better with a copper shelf instead of brass?

PM send to Toykeeper
PM send to Thorfire

And yes agree let’s make the shelf an integral part of the housing and 4mm thick

How about the famous PD68 tailcap?

The Supfire M6 and Roche M170 both have an integrated shelf, the former being around the same price as you propose.

Great idea, always wanted a good SRK. However I would go with an electronic switch version and forget the lighted tailcap.

I’m interested. I’m short on funds, so can’t commit to anything yet, but I like it. One thing I’d like to suggest, though. I know a lot of people like tail clicky for lockout, but I’d rather see lockout through the UI with the side e-switch. It works well on the Olight S20-L2, IMHO. And it will cut down on the major design changes that need to be done to the light.

yes, hence the reason for aiming at that pricepoint. if they can do it so can we Wink
An integrated shelf is also a nice cost reductor compared to copper or brass screwins.

And as far as group buys, yes it is my first, however I do have some experience with dealing with Azian companies.
This is my idea and basic design,
Asus was not keen om making it, but I was sure this would be a great idea.

Hi The Miller,

If you keep the interest list in the second post, every single update of the list will generate update-mails to thread-subsribers and the updated-button in the recent posts page will direct to that 2nd post every time, instead of the really new posts.

Updates to the OP will not do that, so it is better to keep the list there.

Well the Supfire M6 for 40 USD is just the basic version, if you want the “pimped version” with higher output (4000 lumens) and better FW you must add another 50 USD!

I would not recommend to go for a lighted tailcap, but It would be great to have a choice of LED type (Nichia for the photographers and those who want the natural colors or Cree´s for maximum output)

Anyway i´m interested! I was tempted many times to get me such a can but resisted because I din´t want the cheap latticebright LEDs….

Yes the tail switch is ditched for lock out via the side switch, cheaper to make, less parts so no brainer.

Will update OP now

the only two main differences wth the original SRK are the integrated shelf and cell status via side witch.

We are basically asing Thorfire to make a new light, based on proven design, proven pularity, known sale of first batch. They can up the price for their own branded ones and have the best SRK available, we would recommend that instead of the Supfire.
I think whoever i going to build this light is offered a great deal but I would love to see a Happy box SRK arrive Wink

One more idea from the peanut gallery. Probably not for this group buy, but maybe in the future. A “mini” SRK with 4P 14500 and 4x XPL HI V3 emitters! Integrated shelf should dissipate heat well enough. Smaller reflector size would ensure less throw, but who ever bought SRK for throw anyway? Sizing it down to 4× 14500 would make it pocketable, and with the 4x XPL HI V3 emitters, it would still be awesomely bright! A lot of the longer standing members already have SRK-size SRK’s (LOL), but the smaller size would make it unique, and possibly more would be on board for one. Then again, maybe I’m the only one. Silly

One note about the size: the ratio of diameter/length of a 14500 is almost exactly the same as 18650, so the entire body design of the SRK could just be scaled down a bit and still look and function the same. Nothing new to design, really. Upgrade the driver and LEDs of course, just like we’re talking about here.

Hahaha oh yeah a cute little baby SRK
I hope we are getting a nice thing going here and can indeed follow that up with a smaller version.

How a about a name for this current BLF Premium Soupcan?

That form factor would be very very cool, I’m all for it, but I would not like to miss out the chance to make it 4S on Eneloops (+alkalines for backup): the energy density will be a little less, but the batteries are safe and available everywhere. And you have 4.8V nominal and great current capability (at 10A you still have over 4V to play with) to make it a real hotrod.

Two please! I was just showing a friend some SRK videos—one will be a gift for him.

Some thoughts:

  • Nichia 219C — Yes!
  • Bistro UI — Yes!
  • lockout via side switch — Yes!
  • tripod mount?
  • anti-reflective lens?

Thank you for your efforts Miller, I hope this GB takes off quickly! Smile

I really like this idea too – in fact, I’d probably be more likely to buy a 4xAA (4S/Eneloop) version than I would a 4×18650 version. Cool

I’ll take one as long as it stays close to the original design and not get super complicated with several switches and a UI that requires a book or flow chart. I want to be able to turn it on (and it be bright) and off easily.
Thanks !!

OP updated.

And I like the idea to follow this up with a smaller baby (AA and 14500 cell) version when all goes well very much!
We should have a good relationship with the manufacterer/seller by then. But lets start here Wink

And seeing how other groupbuys go, this may take some time, do not expect it in your hand anytime soon.

Could there be a ramping driver with this UI:
O 1 click on (on memorized brightness)
O double click hold second click ramping up from moon to turbo, release when brightness of choice is reached.
O triple click hold third click ramping down from turbo to moon, release when brightness of choice is reached.
This sounds like an awesome UI don’t you think?

You guys are right! What was I thinking? Make it 4S AA for Eneloops! In fact, a buck driver that could handle up to 4S Li-Ion would cover us, wouldn’t it?
