【convoy】H4 and B35AM options are updated

I am also thinking about buying 519A, 4500K. Can you try taking off the glass lens and see if it might be the cause?

I’ve got Convoy lights from some 3-4 years ago and the glass lenses definitely made tint more greenish (but I didn’t rule out the fact that the greenish tint might come from the emitter itself).

Without glass it continues to be green, maybe a little less but still more than the LH351D 2700/5500K mix. Sorry no photo.

The S21D gets extremely hot with 219B Leds.
I measured above 60 °C on the case.

Is this because of the 219B or do other LEDs have this problem as well?
How hot will the S21D get with 519A LEDs?

The max temp should be the same since it has temperature regulation. Running 8 or more amps in a relatively small flashlight will heat up fast regardless of the LEDs.

The 519As are more efficient than the 219Bs (Nichia 519A), but in the end they’ll both get to the same max temp and then the driver will take over.

Is T3 driver compatible with red sst-20?

I don’t think so. I’m pretty sure someone else has tried it and was disappointed.

I asked Simon about it some time ago and he said there was no suitable driver for the t3 + red.

In my testing of Convoy lights, I’ve found that they have thermal regulation but only between 100% mode and 35% mode. They won’t dip below 35% mode no matter how hot they get. That’s just based on runtime graphs & how hot they feel to the touch though, so I could be wrong. It would explain prokolow’s experience though.

Convoy states the S21D driver has:

  • “Temperature protection management inside,After triggering the temperature control, the current drops to a minimum of 20%”.

For the SST-40 drivers it states:

  • “It can control the flashlight temperature not to exceed 55 degrees Celsius, If the flashlight temperature is below 55 degrees Celsius, it will output full current. If it is above 55 degrees Celsius, it will constantly adjust the current so that the flashlight will not overheat.”

I have many of the SST-40 drivers and they do a great job to regulate the temp. Actually I wouldn’t mind if they got a tad bit hotter.

But regardless, with the same S21D driver, I would suspect a similar max temp would result from either the 519A or 219B LEDs.

If that 20% thing is true, that’s a nice improvement.

I know almost all of Convoy’s lights say the 55C thing. That’s just not what I’ve personally observed on half a dozen lights I’ve tested.

I agree that 519A vs 219B in S21D should result in the same max temp.

Hello Simon! Do you ever plan on offering the E21 Nichia LEDs on your lights??

I’m pretty keen to see Anduril on some of the Convoy drivers. I would replace the driver in my M21C-U if one were available, or simply buy an M21D for the onboard charging

Actually, you can buy the Anduril driver for the M21C-U from Hank. The one from D4v2 fits perfectly and you can make an RGB button.

What switch did you use? I did that same mod to an M21D with a K1 driver but I wasn’t able to fit the K1 RGB switch.

I had to make a custom pcb

what about B35AM?

Large 3x21700 SBT90.2 thrower prototype shared on Facebook and then Reddit. It looks awesome! I hope that the Anduril 2 driver Simon said he’d work on will be compatible.

Hopefully there is a high regulated mode like the l7. But given the use of the same battery carrier, it will likely use the 4x18a driver…

I can’t find any anduril drivers on his website, does he offer the D4V2 driver in 6V?

I’ll soon buy a S21A with the B35AM 4500k, but I really wanted something small with a 1800k LED in it. Something like a T3 or even a S2, perhaps a triple E21 S2? That would be awesome. Btw, do you still have plans for a triple S2+

This is the “secret menu” option. You have to email him.
There are no 6V drivers. Only 3V 5A, 7.5A and 9A and boost drivers 12V (idk amps)
