Thanks, exactly what I was hoping for. I replied with a few questions. On paper this seems like a much more practical solution than eyeballing or messing with a lux meter at too close range.

You’re welcome.
Yeah this is what I do when I don’t have time to go out in the cold and focus a light for an hour by pointing it at something 500m+ away.
Using a luxmeter to focus a light at a close distance will cause a decrease in throw when used at farther distances.

D1 reflector is not good enough for black or white flat. It is only good for larger leds like XP-L HI. Me also only got around 60kcd with white flat. You can’t focus it better.

That’s a shame, it would make it the perfect pocket thrower Sad
60kCd is not impressive in a reflector of this size… My Olight R20 with a White Flat does 50 !

My convoy S2+ wf1mm2 does 31 kcd and C8 does 191 kcd. My latest build with that led is an L2 and that does 398 kcd.
Further lights I want to build with WF1:
Nitecore P12

D1 reflector is not good enough for black or white flat. It is only good for larger leds like XP-L HI. Me also only got around 60kcd with white flat. You can’t focus it better.

I just received a D1 and this is my assessment too. It seems the reflector has significant deviations from parabolic. Even with the larger XPL HI I couldn’t get the focus right; the inner part of the reflector was not reflecting the die. I put a 2mm^2 white flat in and the focus problem was made a bit worse.

Some measurements:
Stock XPL HI V2 3A @ 5.4A: 44.9kcd.

2mm^2 white flat at 7.9A (30Q at 3.66V): 79.2kcd.
As the beam is now, the hotspot is the same size as an EE X6 with dedomed SST40, but with a much smaller corona than the X6.

The focus could maybe be improved by a little. Current measured with ~2mOhm shunt at the tail and clamp meter.

So would you have to cut the reflector base down to lower it for the D1 to Focus better? Or raise the LED into the reflector?

I think it is really an issue with the shape of the reflector not being parabolic, unfortunately. As it is now, when looking into the reflector from far away, the inner part (2-3mm) is not lit up. But it is not behaving as other reflectors do when adjusting the height, in my experience. I can’t get the inner and outer parts to reflect the LED light forward at the same time, at any height.

The result is still not terrible. Based on some frontal area estimations, I think the focus problem allows only 80% of the frontal reflector area to be used, for this LED. With the D1S I estimated the reflector to have 1270mm^2, and I got around 240kcd at 7.5-8A. the D1 reflector I estimated to have 530mm^2 and so I would expect to get 100kcd, but I’m only getting around 80kcd.

Hmmm. I’m having an issue but with a different light, an ArmyTek Doberman, the reflector is amazingly deep, and is sitting on the mcpcb, terribly out of focus, maybe their way of de-focusing the XP-L with it’s shitty corona. Shimming up only makes it worse, no matter what LED I have tried so far.

With my GT Mini and White Flat I had to set it directly on the MCPCB and trim the base slightly to get it to focus. I also had to trim the edge of the base slightly so it would not interfere with the solder joints for the leads, and coated the leads with tape as to not short out the light. I got a nice pencil beam – then I showed it to my uncle and he wanted it badly, so I gave it to him!

The reflector was sitting on the mcpcb, no issues with contacts I installed a larger 20mm board. I would have to cut the bottom off the reflector or pillar the LED into the reflector. I have done this before, but I hate dusting up a reflector. This is my 9th Flat White build ( well would of been) and this reflector is not made for this emitter, plain & simple. Big Smile So I put a LH351D-W6 5000k in it for 1780lm and done.

How about blackening the centering ring, and everything else but the refelctor, with a felt tip pen?

You are a flashaholic if you are forced to come out of the closet, to make room for more flashlights.

The reflector is sitting on the mcpcb, (no centering ring) which is white, I did run a black Sharpie over it. Thumbs Up The Doberman came with out a centering ring, the reflector has 2 outer support rings that are relatively tight to the head’s inner diameter, so centering is tight, just the reflector to me isn’t right to focus even on domed LED’s let alone dome-less LED’s. But the W6 is putting out some pretty impressive lemons, and it’s fair to midland when using it outside, so I’m done wasting time on it. Big Smile But thanks anyway’s!

What gasket did you use for the l2 and what did you do for focus?

Removed gasket. Just one layer of kapton tape around led to not scratch MCPCB with reflector. Reflector sitting on that. Wires soldered insane flat. Reflector bottom sides grinded a bit to clear wires.

Oke and centering just twisting the bezel?

Yes but it needed to put some tape one side of the head inside to push the reflector sideways.

I asked Simon from the convoy store if he could get some gaskets made for 9mm reflector hole and he said could.
(1mm² led)

What should be the inner diameter of the hole inside the gasket?

Which reflector is this for? We really need some centering rings for the Osram Flat Whites to fit the L2, C8 and S2’s. Hoop is supposed to be making them but haven’t heard anything in a month or 2. Not sure about the L2 either.

The gasket from int outdoor is for 7mm reflector.(convoy s2+ etc)
The c8 and i believe the L2 use a 9mm reflector hole.

I bought a solid tube of pom plastic and will try to make some gaskets myself. If it works out I will report here.

I talked about WF1 with Simon a week ago and he told me he will get some testing samples after chinese new year and maybe consider putting them in C8. I will help him in every way I can after my 6-7 WF1 builds conclusion and led measurements.

Sweet! Thanks. Can you communicate the dimensions of the gasket with him?

I would be interested in 10 or more of those centering rings. Looks like I have a few people who want me to build pocket throwers for them.

I ordered some POM plastic to make myself some gaskets. All hand work and no fancy tool avaible. Its a little to loose in the reflector but I will make some more later.

Got some good news for anyone wanting to swap the 1mm2 emitter into an MF-04.  The stock isolation ring does actually focus the emitter quite well in this light.  I finally got back to this light last night.  I centered the emitter (trial and error when tightening the bezel.  Once I got it centered, I was able to confirm focus.   Atmospheric conditions are very bad right now due to extremely high pollen from pine trees.  I will measure throw and get some beam shots after conditions improve.  The beam is beautiful and clearly beats my BLF GT which I measured at about 1 million cd.

Not finished yet.  So just reporting some info for those wanting to swap this emitter into a MF04.  Used a thin solder layer as recommended and lapped the stock MCPCB and the emitter shelf.  Used an old MT07 buck driver set to 4 amps.  Using the stock MF04 reflector isolation ring the beam is not quite focused.  At the moment, the emitter is not quite centered (but appears close) and it is visible in the beam.  The hot spot is not sharply defined.  I only measured 1.3kcd at 10.85 meters.  I can't find my favorite light meter to verify this reading.  The light is way too big for my integrating tube.  So no lumen measurements to report.  No indications of thermal sage noted.

Not sure what direction I need to move the emitter yet.  I think it's too high in to the reflector. The heat sinking with the large MCPCB and host makes me think I can probably up the current to 4.75-5 amps.  Any suggestions on that from you folks using this emitter in bigger lights yet?

I'll report on progress when I get another chance to work on the light.  If anyone has converted and MF04, please report what worked or didn't work for you.

EDIT: Stock isolation ring is focused.  Centering the emitter was all that was needed.

Has this stuff been tint and CRI tested? I understand these are no high CRI emitters, but the information still matters.

Anybody try one yet? He also has 1mm WF’s listed.

The tint is probably good, the older black flat was more reddish than greenish at high currents. The cri is obviously low (the only way to get max luminance), it should be stated in the datasheet. Probably around 65-70.

The xml smo c8 reflector is 7mm but all the c8’s with xpl hi came with larger 9mm holes. Im not sure about the L2..
