It’s probably 55 degrees at the driver; given the difference you’re noticing, 55 degrees at the front would be 71 degrees at the driver (and if there’s wind cooling the front, potentially even higher….)

I have the same question, i already asked Simon for more info, but i am still awaiting his reaction

Simon, is there an easy method to change or disable the temperature regulation of the L21a SST40 driver (i have the version with 4 modes only) ?

Maybe by disassembling the temperature controller, or soldering a bypass resistor, or just bypassing it with a wire?

Simon, any ideas about this ?

i didnt get reply from manufacturer,yet.
i will reply you later

@Simon, please let us know when you have more information.

Hi Yokiamy, you were answered here but image links seem broken now.

Maybe he will notice later and reupload them.

Agree. The lamp is just warm outside, but if you disassemble it quickly, and touch the driver, it almost burns your hand.

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.

Simon, is it possible to make turbo mode access only after 2 click, from any position(on or off) without memorizing it?
So it could be 0,1% - 1% - 10% - 40% and turbo after 2 click

yes ,and what driver model?

It could be in driver for SST40 and new 3*SST20

If turbo is only 1-2 min I can’t see point of memorizing it, and it would give more modes, 4 in loop and turbo when needed. Then it could be really “turbo”, not the highest mode

I definitely want it for S2+ with SST40 (and all other models too:)
Is there any estimates when it will be available?

Yokiamy · 2019-08-20T07:26:40.000Z

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.

KevinZA1988 · 2019-08-20T06:13:25.000Z

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.

Hi Simon. Prosperity to you! )
I checked the operation of the Convoy M3 thermal control, it worked at a temperature of 37°C on the surface of the head of the flashlight. I think this is very early, I would prefer the operation of thermal control at a temperature of ~50°C-55°C on the surface of the head of the flashlight.
Was this conceived, or is this a mistake and will be fixed in the future? Are the thermal control settings the same in all new flashlights?
But the function of thermal control itself is very important in flashlights, I was very glad when the thermal control appeared in flashlights Convoy
Thanks!

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.

new headband for H1 is available now

oweban · 2019-08-20T08:50:22.000Z

Looks good!

I saw a report on reddit that the current H1 batch has the new UI (similar to Thrunite), is that right?

Thank you, looking forward to it !

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…

Any update on this beauty yet?

available soon,about in 10 days

:partying_face:

This is a triple SST40 right? (I saw some mention of triple SST20…) Any approximate lumens numbers for this Convoy S12?

Agro · 2019-08-20T09:28:44.000Z

Simon…any news about the titanium AAA lights?

oweban · 2019-08-20T09:30:59.000Z

Triple SST20, IIRC.

Hello Simon,

Does the XHP35 HI 4000K B4-40E have 90 CRI?

not high CRI

Uch why can’t I find it? It is so annoying…

Can someone help with finding this LED? :person_facepalming:
