My only previous application of D-C-Fix was on the inside of the lens (on a P60 drop in I wanted to make floodier). Light loss is minimal (<5%). I’m assuming the bezel unscrews but my feeble attempts have so far been unsuccessful.
Have you seen my videos? This one https://youtu.be/rdwah7HJAJA shows me going into the blinkies. It’s dbl click, short pause, dbl click, then single clicks to go up through the 5 different ones. Your timing might just be a bit off. Once in blinkies you have to advance through them before 1.2 seconds each click. If you stay on a blinky mode longer than 1.2 seconds it locks in.
I also have a video showing the config menu. Once you get the hang of it, it’s easy. The cheat sheet shows the default settings, so just try changing one thing at a time and verifying it worked.
Still waiting to get mine to find out if there are issues or not. :weary:
A while back, I took some beamshots of an EagleEye X6 and a Convoy S2+ triple comparing d-c-fix and a holographic diffusion film from Luminit.
In that same thread, ‘saabluster’ mentioned the layers of diffusion material used inside newer TVs. I haven’t tried any on a flashlight but I’ve had several TVs apart for repair and the material looks promising. It’s also cheap if you keep an eye out for TVs on trash day. 
I think what I had in my head was a very light blending of the beam. The 40° diffusion film probably cuts your beam distance to less than half. That’s not what I was wanting. The 10° looks promising.
Is the DC FIX stuff available in different amounts of diffusion? That looks closer to what I wanted.
Where do you buy it?
Beam shots before/after DC-Fix? I have some for the BLF-A6… not the greatest shots, but it might at least give some idea what to expect.
It’s worth noting that it does not change the tint. It just blends the various parts of the beam together for a more consistent tint. Usually the hotspot is one color and the spill is another color, but a diffuser reduces that by blending them. In case anyone was wondering why the light on the right looks warmer… it’s not; it’s just more consistent.
Yeah. That looks pretty good. The last time I googled DC fix I got all kinds of colored films and such and no decent places to buy it from.
Sureeeee…… Now it works exactly as expected. My timing on the single clicks might have been too slow. The bike mode is nifty 
I think the stuff in my beamshots is the ‘sand’ variant. A listing on Amazon seems to call it ‘milky/sand’ and d-c-fix’s site calls it just ‘milky.’
Have you tried the ‘Scotch tape method?’
Here is the manufacturer’s page with their diffuse self-adhesive variants.
Another trick, go backwards in strope:
Strobe Modes:
The normal way (RAMPING: 2x, 2x, Y clicks [Y= 1…4] ) is time sensitive because of the lock in modes. And I got PMs people are not quick enough for the Y clicks, because the Y have to be done right after the second double click.
If navigation is hard, try:
RAMPING from off/on: Double click, double click, 4 clicks in a row. Now you are in the 5th strobe = 10 sec beacon.
MODES from off/on: Longhold (over 1,2sec), 4 clicks in a row. Now you are in the 5th strobe
Now you can go back via click&hold. You can go back 4 times, then comes OFF.
If you go backwards you have time to do this.
I’m glad you got it sorted. :+1:

I got two Q8 yesterday and work so far both perfectly.
Thanks to all those who have made this project possible.

To remove bezel, place on tyre inner tube(free from tyre repair shops).
Hold head, press down hard and turn anticlockwise.
Here are a few detailed pics of my near perfect Q8. I've found nothing to complain about with the workmanship or performance. Comparing this by eye to the performance of a few other lights with similar specs, my sample somewhat exceeds the factory specs given, without any modifications. I'm using Sony VTC6. I plan to bypass the springs.
I disabled the strobe and all functions of the indicator light. I do miss the double-click from turbo to get back to the previous setting, like the D4.
Thanks again to Miller and the team for the best bang for the buck I'll ever get in a flashlight!
MAD777, that first pic makes me hungry! It’s early here, finishing up a cup of joe, and that looks like 4 over easy eggs…. my Q8 is hung up in Houston so I can’t even make toast! 
Nice shots, looking forward to seeing this light…
Number 1 is hung up in Houston, still, number 3 is now in ElPaso, TX and number two is still sitting in LA. I recently ordered a couple of things from Banggood that have caught up to number 3 light, in ElPaso, even though the shipping seemed much different. I guess they’re playing with my number 2 in LA… hope they leave the cells in it when they’re done.
I'm adding this as a feature improvement: if strobes are disabled, 2X click from a 2X click invoked turbo will restore last level.
Oh, I never thought about it before, will try it but have little problem here, could you please inform me store that selling clip for it?
How about a triple Q8 threat with one of these:
You wouldn’t have to worry about trees in your way, on turbo, it’ll simply turn them to ashes.
I guess you already know that after double click to turbo you can click to OFF and the next click brings up your old brightness level?
Right now I don’t know if Toykeeper has a RampinglOS version for the Q8.
I wrote RampingIOS, so definitely will work on a Q8. Both support FET+1 fine.
