Simon, are there any updates on when these might be available? Thank you!

Thank you Simon, and also thank you for your hard work.

I totally understand. Thank you for the reply.

Are those the 50mm TIR ones?
Yes. M21K and M26E.

What emitters will those have?
He hasn’t released anything about them other than the TIR size and that photo, as far as I know.

Simon, the 22mm 12A SBT90.2 driver keeps failing. I’ve had about 5pcs fail with this component. Another person has also reported multiple drivers failing with this component. Rated for 12A, but I measured as high as 22A so I’m guessing it can’t handle the high current. Might need to source a higher quality chip. When it fails it creates a short circuit which is a bit dangerous. This really needs fixing.

Is that the diode for RPP?
it’s FET , The actual output current is affected by the voltage value of the led, the resistance of the battery, and the resistance of the spring.
If you test directly with a high power DC power supply, it’s possible to get the 22 amps you’re talking about, but in practice it shouldn’t be that much.
I measured it with a Molicel P42A and my clamp meter with 8 AWG wire. The P45B is even higher. At turn on it measures 4860 lumens, the same measured lumens as the 3X21D with 25A CC driver.

The resistance of my test instrument may be a little too large, so the measured current value is a little lower than yours.
Considering the actual operation of the flashlight, the voltage of the battery will drop, and due to the effect of temperature protection, its current has been declining.
It might be for polarity protection, but I did not investigate this further. When it dies it fails closed. It’s a SS54 diode in the SMA package. Common Schottky rectifier diode. It can get so hot it cracks and desolders itself. This component is rated for 5A maximum sustained current.
I assume this issue will get worse with better cells, P42A/P45B/P50B?

I agree as from my experience I have seen SS34 (3A rated) diodes get incredibly hot under 2A load for 10mins. This diode is very unreliable, specially the cheap ones.

It appears to be used as a freewheeling diode between positive and negative LED terminals. I have no idea where a sufficiently high current to damage it should even come from in this place. The short leads to the LED and the MCPCB should not have enough inductance for this.
Yeah, the orientation would suggest this is fly back diode. Maybe the heat came from the MOSFET next to it? There was molten solder on it in my failed driver.
Yes. Looking forward for the new M26E!

Yes, Andruil 2.0 would be a big improvement for Convoy!
The sideclick UI and other driver quirks are the #1 reason mentioned on Reddit as to why people will not choose/recommend Convoy.

Max current aside, that diode failing is a BIG problem and that driver needs to be updated. Please look into this as it’s not a good look to have multiple customers of mine shipping their flashlights back for repair.
Every other driver seems to be very reliable, but this 22mm SBT90.2 FET driver is very unreliable. Sold 18 units and had 5 returned so far. That’s a high failure rate.

Anduril 2.0 would only be an improvement IF the driver uses the Atty1616 and is configured correctly. I want to see it shipped out on the Simple UI set to max brightness. It’s a pain in the arse to have to switch to the Advanced UI, configure the Simple UI to max brightness, then switch it back. I’m a dealer and doing this on multiple units is frustrating. Then have a customer factory reset it is a big headache. If this can’t happen then no Anduril, thanks.
