Place the spacer for optics on top of it rather than using two layers of thermal paste or solder.

That is a great idea, scratch the solder mask off the entire two traces of the board and solder two 0.6mm copper plates on top covering (most of) them (triangles will do the job). It will give you an almost (or entire) DTP performance. It will be a pain to solder the wires then, so make sure that you already apply solder blobs on the wire-pads during reflow!

Don’t forget to apply pressure while soldering those two copper plates. Thicker is better (if no optics involved). If you use aluminum reflector you can connect one of them to the reflector to get double sided cooling (isolate the other one)

djozz, clemence thank you for your ideas! I will try to find suitable spacer, of course. But now xhp50 with native H03 copper mcmcb is more cheap and convenient. Although a bit worse in CRI and r9

The gain decrease in lumen from 2,5A to 10A and to 16A is amazingly steep. I imagine the heat they create must be more than 60C at the body

Oh, they get WAY more then 60C. I desoldered the wires from the mcpcb when doing a turbo test on my first triple in less then 90 seconds.

Now days I use thin wires to reduce the current and I use S2 instead of the S2+ since it has a thicker spacer.

With 10A and the S2 or S8 host with a copper spacer I can generally get around 60 seconds before it gets too hot and starts thermal regulation.

I tested a few other tube lights today for more comparisons to the earlier numbers:

Triple XP-G3 mixed tint 85CRI did 1150 lumens @ 2.5A with 100m of throw, Turbo was 2900 lumens with 170m of throw all with the 15011 optic in order to get rid of the tint shift issues. With a high drain cell and 14A on turbo lumens jumped to 3400 and a bit more throw.

I have a single XP-L HI with an S6 reflector that makes got 220M of throw at 2.5A and 260m of throw on turbo at ~6A. The best EDC thrower I have.

The best overall setup if you are not worried about CRI is the triple XP-L HI with ~175m of throw on turbo (driver didn’t have the regulated low mode) and ~3000 lumens @ 11A. Sadly the CRI sucks on it.

I am swapping EDC lights out daily right now to see which light works the best for me.

The ultimate setup would be an XHP50.2 or the 144A with a thermal pad and wired for 3V operation with no dome. I would totally rock that setup even if it costs $15 or $20 for the LED as long as it didn’t have tint shift issues and 90+ CRI.

I have some extra 5000k 219C and 319A I could sell for the right price if anyone is interested. Ended up with a few more then I had planned on now that all of my lights are modded already. Only way to use them is to replace existing mods lol.

PM me if you want some of them.

There’s a chance I’ll need the 100 3500K 219C. Maybe more. This is all speculating until I start talking to a few people. I’m in Canada but the LEDS would be needed in the states. Again, currently speculating.

FYI,
I got the 219B sw45k and sw40. But unfortunately in slightly lower bin and said to be from different reels, this time. My rep got me whatever he could find.

I just used up the last of my 219B's. I built a quad VG-10 with them and it is amazing. Around ~2100 lumens but a truly amazing tint. Nice and floody as well (although less floody then I expected) and perfect for a photo light. Already used it to great success for some extra lighting for some pictures. In a quad setup with a TA driver and 20AWG wires it only pulls around ~10A on a HE2 battery, I expected more but glad at the results due to the heat of almost 40W being a bit more then the VG-10 can handle. Now to wait for some more of these. I was doing some experiments last night with my EDC options. All LED's have the dome on. A single 219C 4000k will do ~775 lumens and 143m of throw at 2.5A and ~1100 lumens with 182m of throw on turbo with 6A. A triple 219C 4000k will do ~875 lumens and ~92m of throw (84m of throw with a 15011 optic but more flood) at 2.5A. Going to 2100 lumens and 140m of throw (133m with 15011 optic) on turbo at ~16A (didn't measure it but I think it was around here). A triple 219B 9080 does ~800 lumens and ~96m of throw at 2.5A going to ~1750 lumens and 144m of throw on turbo at ~10A. Based on these results I am not seeing any reason to not use the 219B triple as my EDC as it gives me the best of both throw and lumens. Now to decide if it is worth ripping apart 2 lights to build a EDC triple 219B now or wait for the next batch to become available and build a new light then.....

I am Considering replacing the 219c 4000k in my rey ti with the 219b's.

Or building my second rey-ti with 219b's  (Although that one was supposed to be a single since I already bought LD3 driver for it).

Looking forward to 4000K 219B 9080.

Btw, no need to hold the 3500K 219C for me. Not getting any traction.

Hi my fellow BLFers,

It’s been a very busy month for me, so I haven’t online in BLF for a while until today. I also got an unexpected bad news.
I bought thousands of new Nichias supposed to be ready for you guys this month. But the custom officer called me and said that all my stuff will be held there until I renew my import license. There was a new government regulation just a week before my stuff arrived!
This glitch affected many uninformed Indonesian importers. And I’ve been running around here and there to take care of it. And the to-do-list bureaucrazy got it so much more complicated than on paper. My fellow Indonesian should familiar with this kind of hassles here.
The hardest part is to get the legal company location validation as my current company location is different from what it was on the previous license. And the officer was on tour of duty outside his office without having any replacement, crazy huh? And that’s just one of many small little troubles I faced.
So, for those already put their money to me for the bulk orders, please be patient, I’m on it. The progress even though slow, is near completion within this week.

Thanks for your understanding,
- Clemence

clemence, I feel your pain. Fighting bureaucracy is only for the bravest of heart and I hope you do not loose faith.
You have done a tremendous job on the last group buy and I envy your energy and commitment.
Do not worry about us who just earn the fruits of your work. If the next group buy takes more time so be it.
Thanks for all the great work you do for us. Thumbs Up

A pox upon the bureaucrats. Thanks for putting up with that crap (at least in part) for our benefit.

I finally had time to put together an X6 triple using three 219C R9050 sm403 emitters and the result is beautiful. Using the Ledil optic I get absolutely perfect tint. Depending on the output tint deviation i.e. Duv is anywhere from -0.0008 to 0.0019. So practically no noticeable shift either way. CCT is 3970-4022 K. CRI Ra 91-94 R9 63-76, again better on the lower modes.

Here’s the max mode with dr.jones h17f.
