If your refering to the cometa zoomie fiasco, that light doesn’t count. We mean a reflector type light.
The A8! The Cometa came well after and isn’t BLF, that’s another forum CPF or something similar.
Nothing compared to the new BLF projects but it all starts somewhere. Can’t believe no one else remembers it. I still use mine occasionally.
Here’s a link….

Wow, that was 5 years ago. You can’t even buy it anymore, I assume. Flashlight technology moves fast. I think it’s time for another 26650 light.
We could take the A8 and install a TA driver running NarsilM, add a side switch and maybe make the head a little bigger to fit a triple reflector with xpl emitters. Like a 26650 version of the Sofirn C8F. IDK, but I like those kind of lights.
I think a triple w/xpl emitters in a 26650 should be the next project.
Why not a quad? Better efficiency at the same lumen output.
I can’t remember who asked… but the inquiry to Sofirn about a 26650 C8F has been submitted to Tracy.
I recently received a PM from Tracy on something, I will also present my interest bout this form to her.
More emitters makes the reflector smaller. Maybe 4 would work well? Sofirn already has a small triple reflector and Cutter carries a triple 5050 mcpcb that fits it. Triple 3535 mcpcb should also already exist. I don’t think I’ve seen a quad reflector light with a head under 44mm *which is C8 size).
I asked about that. No one currently makes a light like that so it would be unique. (Triple or quad reflector light with smallish 44mm or less size head, side switch and 26650 body) I think the closest was the Shadow SL-3, but it had a 64mm head which made it kind of bulky.
I photoshopped my Convoy C8 head with my Supfire 26650 body to see what the proportions looked like.
44mm head seems to not be too bulky.
I would like to see a 26650 C8F and have asked.
I just received a UT02 and I really like the dimensions. Button area could be smaller OD IMO. That would bring it closer to the C8F in 26650 form. Just strange that so much throw is in a package only a couple MM longer than the C8F. UT02 is a neat light, I like it.
If you want throw then you would use a single LED.
Triples and quads are mostly TIR.
There is not much diameter difference between 3 and 4.
I don’t care about throw.
We are only talking about a reflector based light, not tir.
Then there is no reason to use a reflector instead of TIR…
A TIR will be more compact and give a nicer beam profile for up close use.
There is also no use for 3500 lumens up close.
You can still use a TIR flashlight for longer distances…
There is nothing that magically stops the beam past a few meters that says “NO YOU CANT USE THIS FLASHLIGHT THIS FAR”
(hint: flashlights have more than 1 brightness mode)
.
The point is a TIR will be smaller and more compact than a reflector.
There is also little difference between a triple and a quad in terms of the individual optic diameter, so it is a better choice to go with 4 if it fits (which it will, in something that is 26650 size) because the efficiency increases the lower you run LEDs.
So 4 LEDs making 2000 (or whatever) lumens will be more efficient than 3 LEDs making 2000 lumens.
That means longer run time. Which is again one of the main reasons to use 26650.
Wrong. First of all, tir style triples/quads using a 26650 body with side switch already exist, so there is no point in making another one.
Second, reflector based lights give off good spill lighting unlike tir. You get a great beam pattern with both spill and distance. This is proven in the C8F. It’s great for walking at night or general purposes. It’s also proven with my Supfire which has an xhp70 in a small OP reflector. It’s also proven in my DQG Tiny 7x xpg2 which makes a nice hotspot, but has very weak spill requiring me to wave it around as I walk.
Obviously. You use the 3500 to see far distances, then drop it back down to a lesser output for walking around, etc…
- Soda can lights like the BLF Q8 already exited. 18650 lights like the BLF A6 already existed.
The point was to make a better and cheaper one. Not to make some revolutionary strange thing never seen before.
- Who told you that TIRs make bad spill?? Have you ever used one?
The benefit of a TIR over a reflector is that you get a more gradual transition between spill and spot unlike reflectors which have everything the same brightness and then a blinding sharp spot in the middle.
This is better for up-close use.
You also don’t get a flower shaped spill like you do with multi-reflector flashlights.
3) Maybe instead of being rude and just saying “WRONG” you can spend some time doing research on different types of optics.
Which of those TIR pics are triple or quads? Those were the discussion and should be compared to the last Flower pic of the multi emitter reflector light.
And I still say… There is also no use for 3500 lumens up close.
The first pic is.
The one beside it is reflector, as you can tell from the sharp spot. (same light but 3 different LEDs)
The third is quad-reflector.
Was it not obvious from the pics?
Wrong. The point IS to make a revolutionary strange thing never seen before. Something that does not currently exist on the market. Something in between the size of a Q8 and A6. The Q8 head is 59mm (4 x 18650) and the A6 head is 24mm (1 x 18650. I think we should build (a triple or quad reflector) with a head roughly 35mm to 45mm using 1 x 26650. This has never been done as far as I know.
