BLF style 18650 1s thrower( poor mans Olight M2X)

Thank you Mitko for sharing this with us.
Baked swap emitter and driver dedome xml2 u4 od, A6 fet+1 177,250cd 842m @5m
1,376 lumen after 30s no ar len yet, order some yesterday.

Totally not seeing where it could have shorted.

And that beam profile is awesome! :slight_smile:

Nice Tim.

That hot spot is KILLER.

Any chance of some beam shots at night, after you get the new AR lens installed?

I'm anxious to see the end results of your upgrades.

I just disassembled mine. It's in the oven now

Thank ARsee, sure if I have time!

500° for an hour turns out nice.

I baked the pieces standing individually and not assembled. At 30 minutes, I turned them end for end. ( I noticed the difference in color of Tims ).I assume his light was assembled when baked?

I separated my pieces because it allows better heat transfer

Looking good ARsee!

Hm, actualy its the best baking i have seen so far - i will bake the next one definately

Yeah and thats the best host part actualy, i had HD2010s but this reflector is great, the beam profile is even better than M2X one

However , ARsee`s driver by default is different from one that i got, also the driver retaining ring too: lets juts hope they dont “upgrade ” the reflector too

That is nice, both Tim and ARsee!

I added an assembled image above to show the blend of the pieces ;)

I think that's the color I saw on the proto Q8 prior to it turning lighter, more like copper. Initially under heat, the Q8 turned a darker reddish/brown color like that, then lighter copper reddish/brown, then turns more like a deep gold. I did mine on the gas burner though, so probably much more heat.

I actually like that baked color quite a bit. Much better than the original conditions.

Don’t get me wrong guys. This hotspot looks nice but IME I think by better centering(lifting reflector slightly more over led) light could/should gain greater candela performance, and of course that will result in smaller hotspot.

I can’t judge by the picures , but i would guess it’s the opposite thing , reflector needs to go closer to the mcpcb .

One would never fix the emitter properly if the emitter is on a 16mm pcb: ever
thats why our BLF fella got only 170k candelas
26+ mm is perfect

Even so its a great result for a 14$ worth flashlight, and its so old style BLF…something that we do miss great time lately

Did anyone dedome the stock led? Can we confirm it’s a u3 xml2? I’m ordering parts for an other project and I’m still in doubt of ordering an U4 emitter for this light or use the stock emiter.

Yeah it is, i used it in a x6 host and got actualy quite good results, its something like u3 1A but you can never be sure for the exact tint

Thnx Mitko

Yes you could be right here… In that case it is no problem to take pill outer ring on a lathe or with file. There is even possibility of dremmeling mcbcb or even reflector base if needed.

Yes it is only + to have bigger mcpcb but in a lack of it I also don’t see any problem in fitting 16mm noctigon. Little file working and dremmeling won’t kill anyone :slight_smile:

Edit: I think I got you know Mitko (The pill can hold 16mm pcbs so i lowered it by 3mm, filled the gap with a thermal paste/ Cu pads and used a 26mm 3535 mcpcb)

Pill by default does not have enough height? If so we could also sacrifice 1 16mm noctigon and merge it with other 16mm one.

This will be easy 300+kcd light with old style XP-G2.

For whatever worthiness, I added an image of the stock board/LED in THIS POST

I am afraid dremeling wont help here, the reflector base is quite thin: and for best results the emitter bracket should be thin as air: using that kind of bracked is impossible with a 16mm mcpcb cause the reflector will ” hit” the driver wires thus causing a non perfect focus, one should use at least 22awg ones- even using 26awg wont help, tested already

As i mentioned before, the pill should be lowered by like 5mm( ofc filling the internal gap is a must), and using a 26+ mm pcb brings things to where they should be- no more loose reflector and a perfect well centered emitter and hotspot

I am thinking about contacting our russian pill crafter Kiril about CU pills, would be a great to have some of those
