In this review (Convoy S21A (Short Technical Review)), thermal control behaves well. Perhaps the problem is only in M3, on S11 I have no data.
I definitely want it for S2+ with SST40 (and all other models too:)
Is there any estimates when it will be available?
After removing the NTC of the driver, the temperature regulation is gone.
I am very happy with it now, the light now works as intended, just full power on max (and yes, it does get hot after a couple of minutes, but still a lot better then the Astrolux FT03 though)
THIS is how i did it
Probably, this is more or less a matter of (inefficient) thermal conductivity. If the driver gets hot like crazy but the host structure around it remains much cooler Simon should look for ways to improve the thermal transfer and dissipation. I could imagine that the driver does not make good contact to the M3 host or cannot dissipate the heat due to non-conductive materials.
I faced the same situation with my M3. No matter how often I restart the highest mode, it never really gets very warm on the outside.
Have you guys tried stuffing the driver cavity with silicone cubes? I found it worked well with a Convoy S3 and 5A 4-mode Convoy driver. The host did become hotter* before thermal regulation kicked in. In the M3, a lot of the driver’s heat should be absorbed by the silicone cubes allowing for longer turbo runs.

Since the drive detects the temperature of the component, not the temperature of the surface of the case, I have raised the threshold for temperature protection at around 60 degrees.
In addition, more heat-dissipating rubber blocks can be added to the driving surface.
Looks good!
I saw a report on reddit that the current H1 batch has the new UI (similar to Thrunite), is that right?
Sorry I don’t fully understand the picture. The circled spot is I suppose the thermal sensor controller, but what should we do to disable it if we don’t want the temperature control on the SST40 4-mode driver? The circled part has to be unsoldered? Pardon my ignorance…

This is a triple SST40 right? (I saw some mention of triple SST20…) Any approximate lumens numbers for this Convoy S12?
Simon…any news about the titanium AAA lights?
Triple SST20, IIRC.
That is one good looking headband Simon!
Can someone help with finding this LED? :person_facepalming:
Do some LED bins only exist on paper? Seems that way.
I also tried finding that LED the day he launched it… Nothing!
Yes, I think some only exist in spec sheets. Kind of like “if we were to produce some, this would be the item number for it”.
For endeavors such as this, Octopart is a great resource… just search for the Cree order code. Pretty much anything I’ve found has a 1000pc MOQ though. 
AVNET supposedly has it in stock (with the 1000pc MOQ). Other places such as Mouser and Digikey also list it, “non-stocked” with 1000pc MOQ meaning that you should be able to place an order (for 1000pcs) and they’d procure it for you.
Now if you don’t mind going for the ANSI versions instead of the EasyWhite versions, you can get the XHP35-HI 4000K 90-CRI in B4 flux bin (XHP35A-H0-0000-0D0UB40E5) from Mouser in 1pc increments for USD $6.50
