I think you need more candela, not lumens (and the accompanying watts). Even running the same driver and led in the M1 will probably be a large improvement for you. Carclo 30 mm TIR (10755) could probably be made to work in the m1 with a custom spacer. It’s 14.3mm tall vs the reflector at 23.2mm. 7.2° beam with the HI and about 32cd/LM. ~25kcd would be pretty effective and sustainable IMO.
It happens someone here may be able to help with that 
Hey BLF,
Today my thread celebrates 5 years.
And ATM it has almost 200000 views (which doesnt looks impressive nowadays, but I could never expect such numbers 5 years ago).
The BLF community was very kind to a random guy from non-friendly (toxic) area.
Here Ive got some good experience that I didnt had before. I was quite young and probably made many mistakes, but people here were so polite and rarely sent any negativity to my side.
This thread have helped me a lot, now its time to go further.
As some of you know, I was used to use someone`s else resources to make things. From one hand, I had people from whole over the world, that have high “internal quality” level and were happy to get parts if they are top notch. At the other hand, I had people that are hard to achieve great results with (even if they are doing their best) because of low “internal quality”. Ive tried my best to close this gap (learned so many measuring and hand work techinics, build many special tools and machines to mask machining imperfections), but at some point I started feel myself as gymnast in split position.
I cant say Im 100% ready but I just dont see other ways. I need my own cnc machine(s).
For this reason, I have not invested in materials and machining for a while, trying to minimize money frozen in parts. And thats why I wont restock parts for some time more.
I have removed sold out parts from the OP and each part amounts are updated.

Congrats kiriba-ru. 
Kiriba-Ru
I have placed a few orders with you and it has always been a great experience. Thank you for offering these parts and for your excellent service. I wish you the very best and look forward to new parts. I’ll take the M2 quad spacer and two U11 spacers from this list (If that is ok and I’d be happy to pay you some for U11 spacers, especially since I would be getting two), then I’d like to add 2 s21a spacers.
I’m hoping to see the maglite heatsinks come back and maybe a C8 6x spacer like Led4Power used to sell.
Thanks!
What happened to S2/S2+ spacers? I thinking stocking up some more.
Congratulations. I don’t need anything right now but have been pleased with my past purchases and the way you handled the orders.
Last batch was produced two years ago. Only now they are sold out.
I used to get full rod (3m=10ft) of copper and run cnc batch that used most of this rod.
Today is not best time for another batch. Not only because Im trying to save some funds.
Raw copper prices have grown almost twice last year:
Congratulations for your anniversary! Your sales thread is great. 
I was always very satisfied with my orders from you. Keep up the good work.
PM send to order a Convoy C8TT heatsink head, S2+ aluminium triple pill, S2+ copper single pill (no lip around pcb – for 20mm boards), Brass contact rings. Many thanks.
Hi, do you have a copper spacer for a Convoy S11 host for a quad MCPCB? Thanks.
No.
Since I have some 30mm copper rod, we can try to make mini-groupbuy for Cu S11 spacer.
Thank you. Do I need to do anything, or we wait to see if anyone else is looking for a spacer?
Sorry, I’m new to all this.
I will check my PMs, I think you are not the only one whos asked about Cu S11 recently.
Very much appreciated your offerings - wish I had more time for the mods. Been very happy with past orders. Congrats!! :beer:
It’s good that you are here with us. I have always been satisfied with your parts. I still have many unused items that I might use someday. Or I’ll sell them.
In the future I would like to see a solid aluminium triple pill for the S21A to keep the flashlight lightweight.
Yes. 6063 Al would be great to see for more convoy pills.
Hi Kiriba-Ru!
I’m new to this, but very excited to maybe get my hands on a c8tt head, and also to see what new things you might be working on! I would like to order the following items please:
I’ve also sent a PM that includes my address. Thank you.
Hi Kiriba-Ru!
1. Is it in stock?
2. Just to check: is it a complete pill, that fits for triple S2+ build (no need for the spacer)?
Sorry, all S2+ pills are sold out. I don’t think I will restock them.
I think I have to share some extra information about current situation. Have not done this earlier because there are still no visible progress.
I’ve tried my best to get a ready-for-use small CNC mill (like tormach 770/1100) or used VMC (Haas minimill/Syil X7/ Scyfire VMC) but had find out that things here are even worth than I expected. Country is closing from the inside, amount of imports flowing down for many years, taxes and bureaucracy are raising each year. All this makes new import machines very expensive (like US price multiplied by 2.5-3), same time deficit (and raising costs of everything) don’t allow used machines prices drop as fast as they should (I’ve seen several 15y.o. HAASes that cost more than brand new model in States). I have looked over several hundred thousands listings, and could not choose anything because main options were CNC router or 30+ y.o. heavy mill with punch tape input or 4k ROM.
During this period, I have also made hundreds of phone conversation with people that sell/upgrade/manufacture machinery, but again, I could not expect that thing here are so bad. People just don’t want too learn using someone’s else’s experience. They offered many funny machines (like heavy 2 ton mill with direct driven small nema motors, or bf20 with modern fanuc CNC and servos), but they are not able to find out how one or other thing should be made based on worldwide experience (read-not able even to copy imported technologies).
“If the mountain won’t come to Muhammad, Muhammad will come to the mountain”. I’m going to build it myself. This is not right way. Do not repeat it. Just get tormach or used Haas.
I’m renting a small place for this needs. A place owner was not able to remove his machines from this place, so I could not start repairing work. Need to work hard next several weeks to make it suitable for my needs.
I’ve bought few small manual machines by occasion. Just find out that person I’m calling is different from the others (mentioned above). I don’t overestimate my machinist skills and I have no plans in making big customer work using them. Probable they will not pay off themself, but I’m ok with this because they are valuable and they do not losing value (because of some factors mentioned above).
There is just one small thing that can justify why I have not made big progress in 3.5 months. Things are really slow here. I understand that country is not small but since start of this year I’ve met dozen situation (both as sender and reciever) when delivery took more than 1.5 months. Each day I met situations when something that should work doesn’t. Yesterday I could not get some equipment unloaded from the truck because heightbores forklift has broken batteries, runs on AC transformer and not runs when it rains 
.
I don’t know how long I can accept all this.
