Officially 4K
But don’t be surprised if it does significantly more 
DavidEF, I don’t know nuthin bout standard SRK’s, the Q8 will be my first, but TomE went into dimensions on the first prototype extensively here.
and specifically stated this:
- outer dimensions are dead-on with standard SRK’s at 59.0mm head, 50.0 mm tube, 52.0mm at tailcap, 135.1mm length
Post #3348 and post #3390 should answer this: ~5,600 lumens. Our official line has been 4,000+, but as you can see, proto #1 did much better. Also, add ~400 when the springs are bypassed, maybe another ~400 if using SONY VTC6 cells. Proto #2 has double springs, so we should see higher #'s stock (no bypassed springs) than the stock proto #1, but all depends if other changes have impact.
This is all based on my very unofficial PVC based lightbox, but I've done a ton of light measurements with it, and seems to be in the ballpark of accuracy.
looking darn good! is the reflector the same as prototype 1?
Thorfire is shipping two prototype V2 to Tom so we know in a week KR so.
We don’t know yet, the prototype has not left China yet. Tom will know soon…
I looked at the pics carefully, comparing to proto #1 in hand, and I'd say the reflector is identical for the part we can see in the pic (top view). Dimensionally, the reflector cups look identical, and the cup wall separators look identical as well. Yea, I was concerned bout that as well.
Also looks like the LED alignment pieces are the same (round), and the underlying MCPCB is still white, but could be the LED's are centered better, hard to say for sure, if #2's are perfectly centered though - still look a little off. Honestly though, even with off centered in #1, I can't tell by the beam or output.
Good to see that the Q8 is another step closer to being available. I won’t order the VTC6s just yet though!
Just noticed the LED indicator in the switch .
Looking forward to this sample’s review 
I have a very hood feeling about the driver !
I love that hood feeling!
Hahahahha:D
Damn g
Yeah we can’t wait what Tom finds inside!
Looks fantastic!!! :+1: … 
Well Tom kind of stole the Q8 thunder with that monster light. Where do we sign up for that? What does that get like 2 seconds on turbo before meltdown protection kicks in?
Tom I would think with that many LED's you could purposely misalign them in a symmetric way, like put them all on a radius from the middle that's 0.5mm too large, and this would likely solve the hole in the beam. It would ruin the hearts and daggers symmetry though. It may also end up with a dark ring around the middle. Of course that only requires remaking the ledboard lol.
Yea, on VTC6's @4.20V I hit 37K @start, and then 10 secs later it dropped to 33.5K. 10 secs is about the limit I'm using. Outdoors, a little longer.
I certainly ain't touching those wires again any time soon - I knew the wiring was gonna be the worse part, and it was. I almost seriously considering buying another one for like $62 off of eBay, and using XHP50.2's this time - that would solve the donut hole. Actually the beam pattern looks great on a white wall - much more evenly distributed than the 3X, 4X, 5X lights -- accept for the black hole of course...
I'd also like to measure tail amps on that light, but for that, I'd have to do a bunch of cuts and jumpers on the tail and wire in a big thick wire or 2 to hook a clamp meter around. I'm think'n it's over 40A for sure, for 45A it would be 15A per cell, maybe 300 watts for the 2S3P, based on djozz's tests here: https://budgetlightforum.com/t/-/30860/275, if I did the math right.
Put me down for one, please.
Can I be added to the list please. Looks amazing so far!
Looking forward to the Tom Test.
I still say, when and if the Proto is approved, they should send out 20 or so units first to get a feel what the production units will end up like. If they end up having some problems, it’s a lot easier to fix 20 units, and address any changes in production and QC, than it is to have 1000+ units out in the wild with problems.
I’m not talking about sending out 20 free flashlights, just picking 20 or so volunteers to pay, receive the light, and report back. Then if all goes well, let it fly. I’d volunteer for the cause.
I’d be happy to be a paying reviewer, as long as any early defects are replaced for free.
Sweeeet!
