Keep in mind that even a 2.8A S2+ will get too hot to even touch if left unattended even a few minutes. By āunattendedā I mean not having an ungloved hand wicking away excess heat. Had one tailstanding for just 5min or so, and when I went to grab it to turn it off, I just dropped it, as it was like grabbing the business end of a curling iron. Needed to grab a shirt or something to use as an āoven mittā to just get hold of it long enough to turn it off, and then drop it again ātil it cooled off. Not Fun.
Tubelights have pretty lousy heat dissipation, no fins or anything to help with that, so build up heat fast.
āSmartā lights will throttle down on their own, but ādumbā lights will just keep going full-tilt ātil the LED cooks, or even the driver pops, or worst case the cell itself overheats and vents.
You really need a bigger light for a) more thermal mass to soak up and spread out the heat, and b) way more cooling fins to dump that heat to the environment.
Sorry to hijack the thread, but I really appreciate the help and advice from you guys. The S2 on my helmet is running a Bistro FET+7135 and the temp sensor is set to about 130Ā°F (roughly hot water temp from the faucet) before turbo drops down. I also have it set with moonlight off (donāt need it on a helmet light in a fire) and 4 mode (25/50/75/100) light levels. Itās perfect for my needs, but Iām sure a TIR optic would improve the beam tightness. I was running it at 50/75 for most of the fire with no issues, but there were a few moments when I kicked it up to turbo for a specific task and it felt underpowered.
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. Itās 14.3mm tall vs the reflector at 23.2mm. 7.2Ā° 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
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 āinternal qualityā 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 āinternal qualityā. 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 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. Iāll take the M2 quad spacer and two U11 spacers from this list (If that is ok and Iād be happy to pay you some for U11 spacers, especially since I would be getting two), then Iād like to add 2 s21a spacers.
Iām hoping to see the maglite heatsinks come back and maybe a C8 6x spacer like Led4Power used to sell.
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 ā for 20mm boards), Brass contact rings. Many thanks.
Itās 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 Iāll sell them.
In the future I would like to see a solid aluminium triple pill for the S21A to keep the flashlight lightweight.
Iām 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:
1x Copper spacer for triple Convoy S21A ($5)
2x Convoy C8TT heatsink head (bare with driver ring and o-rings) ā ($12)
