I ordered three from AliExpress on the 27th, managed to get in on the group buy by asking nicely with a pretty please. I lurk here a lot but never had much to say, so I never bothered making a BLF account before now… I’d been watching this thread for about a week and a half but didn’t have funds ready until the 27th, was stressing that I’d miss out on the group buy because I’m “not” a member of BLF (even though I certainly FEEL like I’m part of the community here, lol, I’m just the shy one droppin’ eaves from the corner) but it all worked out in the end! Big Smile

So, I’m sorry if this has been answered already but it’s been a long haul getting through this thread and I’m dealing with a bit of information overload here after reading through 30 pages in what little spare time I get these days. Did we ever find out if the LEDs will be V3 1C or V3 1D? In post #147 djozz talks about this, but I wasn’t sure if that meant something like “we don’t know which will get sent to the factory from the distributor but every light will have emitter X” or “our order from the distributor will contain a mixed bag of 1C and 1D emitters but each light will contain four of emitter X” or “our order from the distributor will contain a mixed bag of 1C and 1D and each light will have four random emitters” (ie, potentially a light could be made with three 1C and one 1D) …like, it’s a lottery, but what KIND of lottery?

^ I can’t remember if I checked the final tint in my Q8 sample other than: it is a fine cool white tint without hints of red or green.

Will try to do some measuring actual tint tonight if I did not do that already.

d_t_a, that’s correct… on 2 of these Sofirn Q8’s that I’ve flashed Anduril into the side switch doesn’t light up at all. The second one I even downloaded the hex file again just to be sure something didn’t go wrong in the download. So I have 2 Q8’s here that have no light in the switch, none at all, the configuration menu that works for you only works as momentary for me. No idea why. Everything else works fine.

On my second Sofirn Q8, I have replaced the tail pcb with a copper disc, soldered Blue’s heavy large springs directly onto this disc, put 20ga spring bypasses inside the springs. So now, on the same cells (fresh charge) it makes 6379.05 lumens, up from the stock 5775.3 lumens… a 603.75 lumens gain.

Each of the four XP-L HI’s is making 1594.76 lumens.

(The point I’m really trying to make here is that Sofirn built these lights quite well, very close to maximum performance right out of the box.)

Kawi , I had three in my scratch build that drew 21A at 13,000+ lumens, no poof!

The one in my Jaxman is making 3000 plus on two 14500’s. Think it’s at 3A or so in that light.

Djozz has tested them up to 15A.

But yeah, there’s that possibility which is why I asked. The Quad set up may make the difference, don’t know…


On 2 18350 Vapecell’s they go poof…FETDD driver, never seen one make it past 11-12 amps myself…so I quit using the 8awg test loop and Amp meter to test…current pull. I had one 50.2 on 2 Efest 18350 I would charge to 4.0v but it went poof later on down the road…when I put 2 18350 Aspires in it… I forgot.. Facepalm

Hi Dale, were the original springs bypassed already, when you measured those 5,775 lumens? Regards, Thomas

The original springs are doubled, one small one inside a larger one. No wire bypass. And yes, the doubled springs are what gave it 5775 lumens.

Wow! The large springs are actually thicker compared to the original, and the inner spring is quite a bit taller too. And you got 5700 lumens from it?

Makes me excited, as I just shipped you and the others the rest of your orders of BeCu springs, both big and small.

That means you could potentially do a dual BeCu spring array, and perhaps get as good performance as a bypass!

And my Sofirn Q8, with stock XP-L HI’s, is now making 6513.6 lumens.

This new 158.7 lumen gain simply by swapping in an incredibly clear UCL glass lens from flashlightlens.com. This is a 55mm x 1.9mm AR coated both sides glass lens with 99% transmission. The stock lens has no coatings and is 2.9mm thick, so I had to use a thicker clear o-ring, but other than that it was a straight swap. The UCLp in Acrylic can be had in 3mm thickness for a direct swap. I got one of those as well, put it in the light I have listed as an option in my giveaway, charging the Samsung 25S cells in that one to see what kind of final reading it has…

737 lumens gained by acute attention to the circuit’s ground and a lens swap. (replaced PCB with copper disc, Blue’s large springs, 20 ga bypasses, UCL AR coated lens)

Perhaps you could now replace the FET inside of the Q8 with an Infineon one.

Y’all ready?

The XP-L2 Q8 with all it’s tweaks and the new UCLp lens is up from 9453 lumens to 9936 lumens, by merely swapping the lens. Big Smile

Gotta love it when a plan comes together!

Oh, I did 10,200 with SST-40’s quite a while back in the original Q8. Sold that one to Slow2Go earlier this year.

I want 15,000 or more now. Considering how to go about that. The power grid on this one I just got is ready to go, just have to figure out what I’m going to do up top and not spend a fortune doing it. Wink I have some thick walled aluminum pipe here as well as some pure copper that is difficult to machine, may just make a copper core for the heavy pipe and then cut an extension with fins to be able to use 8 18350’s to power 4 XHP-70.2’s. That should be good for upwards of 20,000 lumens and maybe then some. Big Smile Working on figuring it out, this method would enable me to use some components that have been sitting here gathering dust for a while…still would have to spend $100 on emitters and cells. That’s the yuck part.

that would mean your Q8 is pulling between 35 and 40 amps

That might have once been scary, but my M43 is doing 58.8A. Big Smile

I guess ya get a little numbed to it after a while. lol

Edit: Eyes wide open, no doubt, but it takes more and more to be shocking if you know what I mean…

Yep, it has. They told us it would be going up soon after the Group Buy ended IIRC.
And so it did. Wink

I was told the deal was good until the end of October… maybe they just meant the code was good until then… Facepalm

Hmmm… I don’t know anything about that. Sad
Maybe Sofirn or someone ‘in the know’ will chime in. Good luck.

I assumed the Group Buy ended Sept 21 when Sofirn said it was ending that day. Sorry.

djozz started this thread on 9-1-2018, on the first page he stated…

“The set-up:
I will maintain an interest list in this OP for a limited amount of time (a few weeks?), being on the list will entitle you to buy the flashlight at the group buy price.
The lights can be purchased via the Sofirn aliexpress store or via their Amazon store (both US and DE), but the way to buy is different (I hope it will be easy enough for you, this is not something I have an influence on)
For the Amazon stores, Barry will PM you a promotion code that will get the price down to $39.99. Please indicate if you are planning to buy at Amazon, and US or DE.
For the aliexpress store, order the light but do not pay yet! Instead, while still in the unpaid order, leave a message with your BLF-name, Barry will check if you are on the interest list and will lower the price for you. Then (I hope it will be quick) “refresh the order” and finish paying.
Currently there is no limit on this group buy, if more are on the list than they have produced, they will make more.

When will the lights be available?
400 lights are already made, 300 of them will stay in China, 50 will be shipped to Amazon US, and 50 to Amazon DE. That sounds soon enough to me but when exactly the purchase can happen I don’t know. I guess they will show up in the stores and then either you have had your code (Amazon) or you can order and wait for the price-lowering (aliexpress).”

So, the few weeks is up and the Amazon lights have been sold. We tend to gobble up group buys around here, what with 26,530 members. Wink

klrman, it probably should be. More than a little scary, I have to admit.

shirnask, I can’t say if I’ve had that EXACT expression, but I know there’s been more than a few times it had to have been pretty close to that. lol I found that pic when ToyKeeper started calling me Dr. Frankendale… Facepalm

No I thought we got a price of $39.99 or so, I paid 49.99 + sales tax. $56.26 total.

Can’t find the transaction via my Amazon account, but I can find the transaction by my AMEX statement.

Am I wrong, was the BLF price $39.99 or $49.99 ?

Assuming you put in their code before Sept 22, it should be 39.94.

49.xx was the price without the discount code.

The group buy was at $39.99, we got a code to use on Amazon to bring the price down. If ordering from AliExpress we were to put a note in the check-out page listing that we are a BLF member and our member name, wait for them to adjust the price, then finalize the order.

Edit: I think we bought up the available lights really quickly.

Well I got it wrong, I didn’t get the code until after that and purchased the Q8 on Sept 25th, oh well, I still like the light.
