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

Yeah, that might work. If there is a possibility of putting a single ring of copper (wire?) between the pcb and batt tube, that might be even better, to keep as much contact as possible and reduce or eliminate adding resistance.

That’s so dangerous, though.

My 3rd Q8 (second batch) got a trial by downpour and some character marks this evening. I returned home in the dark with a storm pending, tornado watch and all, to find an elderly neighbor standing in the middle of the road staring at his wife’s car in the headlights of his car. Drivers side front wheel has broken out from the ball joint and is jammed into the fender and the road. So I put on my rain gear and pulled out a Q8.

We spent an hour in the absolute pouring rain, manhandling a Plymouth Breeze to the side of the road by the light of a Q8. At one point it got stepped on while laying in the road, picking up a little road rash. No signs of water inside the light, I just dried it off, sighed at the scuffs, and put it on the bedside table.

My only complaint is that I can’t use the Q8 in what I’m realizing is my most used mode: in my mouth. The S2+, my A6, X5 and X6 all work just fine that way. Although it does make my mumbling to myself even more incoherent.

I wouldn’t take it swimming, but my Q8 is definitely weather proof.

Hehe kuddos for the first person to post a picture with the Q8 in their mouth

Sorry. How is that dangerous? The cells are in parallel, and are already conducting through the tail end of the battery tube. I don’t understand what part you are saying is dangerous.

As was said earlier, the wire moving and touching the center brass ring. That’s a direct short leading to smoke and fire.

Maybe a solid copper wire that was soldered into place would be better. This would have no strands to fray and would stay solidly in place.

[JasonWW]

Are you saying put the wire in the tail end of the battery tube?

If so, that’s a different situation.

I would just add some small, flat washers to space the tail board from the tube.

[Tom_E]

No, think he means the ring of wire as shown earlier - sitting on the driver ground ring. It's a kludgy fix but would probably make the problem a whole lot better. I'd prefer a custom made copper ring though, maybe make it removable so can be used only with long cells. If you solder it in place, then not sure what it would do for using shorter cells, but soldered in place would be better for non-techies.

It's an option though. Still think a ~1.35 mm thick o-ring would be bout perfect.

Yep. Big, skinny copper O-rings are out there somewhere, as oil gaskets.

Yeah. The original suggestion was to space the tail board out. My idea was to use a single piece of copper as a washer for spacing the tail board out instead of using individual washers around the screws that hold the tail board on. The small flat washers may interfere with the conductance from the tail board to the battery tube.

Ugh…

Now just MIA because “DHL reasons.”

That the hell does that even mean. It still have over 1800 miles to go before it gets to the local USPS branch…

Sorry for ranting but I get frustrated from shippers that can not figure out how the flip to ship a small package. The sad thing is I can overnight ship something to NYC with the USPS and it gets there in just over 8 hours….

So for an o-ring groove that’s .30mm overall diameter larger, groovr needs to be deepened by 1/2 of .30mm or about .006”.

Sanding cord of approx o-ring thickness may work.

I just received my Q8 ordered on October 16. There is no hint of AR coating on the lens. The end cap threads were not lubed, so I relubed the end cap and battery tube and everything is reasonably smooth now. Nothing major in the QC department, but I’ll list it anyway.

QC issues:

1. Some metal dust in the battery tube and black crud on the battery contact ring
2. Minor ding under the ano on the head
3. No lube on the end cap threads, quite a few dings
4. Burrs under the ano on the battery tube and tripod mount threads
5. Minor dust under the lens and a small manufacturing defect on the reflector

Hey, Charles BridgTec just put up his review of the Q8 earlier today.

BLF Q8 Flashlight Review!

[DB_Custom (Dale)]

Was drinking it this morning, an Ethiopian organic. Really good stuff.

I got my final, 3rd, Q8 in the mail today.

Fresh out of the box with freshly charged button top Samsung 30Q’s it does 5727 lumens at start.

My modified Q8, the 1st to arrive, on freshly charged Sony VTC5A’s, is now doing 8728.5 lumens at start.

Tom E, so what happens when you screw 2nd batch head onto 1st batch battery tube? Did you measure inside diameter of each head?

It follows the tube - batch1 tube w/batch 2 head feels good - batch 1, batch 2 tubw w/batch 1 head feels like batch 2.

I measured what is relevant: the outer diameter where the o-ring lies when the o-ring is removed, and the batch 2’s are wider. All makes sense - o-rings are the same size.

My caliper (“Carbon Fiber Composite”) is not very accurate but, when I measure the same thing several times, the measurements are repeated

I measured OD with o-ring placed and there is difference
1st batch = 49.8mm
2nd batch = 50.0mm

Then measured without o-ring
1st batch = 47.5mm
2nd batch = 47.7mm

The ID of the head in the zone of friction of the o-ring in both units, 50.3mm

Reassembling brings up a problem
The friction of the o-ring in the unit of the 2nd batch is quite harder, I did not think to measure
Then I changed the o-ring for one of Ultrafire C2 lens, 39×1.5mm
I re-measured the OD with the placed o-ring, 49.9mm
Now, the situation improved

NEITHER of my 2 Q8`s have AR coating .
Other wise they seem fine.
Actually` I LOVE THEM `
But I am a little disappointed there is no AR coating on either flashlight .
