Convoy Red driver with 12 groups UI (Now Available!)

It would good for the CSLNM1 red driver to be consistent in UI with other S2+ 12 group/Biscotti.
Not sure if I would personally justify replacing my existing S2+ with CSLNM1 red though, as I tend to allow the thermal regulation to do its thing anyway.

YES. Please put the 12 group firmware on the driver for red LED’s! Currently I’m using an 8x7135 driver instead of the dedicated red driver just so that I can have the 12 group firmware.

Dumb question, what do you dislike about using the 7135 driver?

The only downside should be slightly less battery runtime due to a lower efficiency and maybe a slightly warmer torch

I was all set to grab a C8+ and S2+ with red emitters, but changed my mind when I saw they only had 20% and 100% output modes.
I would definitely be interested again if they were to come with a 12 group driver.

I’m not sure. I assume that Simon would not make a dedicated red driver unless there was a good reason for it.

Everyone using other than 2.5V driver, your emitter won’t run long.
This post is entirely about 2.5V driver but 12group.

Running normal 3V driver is not recommended.

The 7135 driver limits the current though, you could use a 1V LED with it and it’d be fine.
The voltage (curve) of the LED is current dependant, not vice versa.

Oh ok. You might be right (probably you are). I’m not much into electronics nor i like understand them. Can solder some but that’s it. Why i was so specific about V and A is the fact red emitter needs lower Volts to work correctly. No idea how Nanjg works…

You are partially correct, it’ll give okay runtime, just not long at a higher output, the 2.5v red emitter is not ideal on a 7135 driver since it’s designed for a higher Vf. I was also told it’s quite hard on the chips

For others who say it’s a non issue, why would Simon design a dedicated 2.5v driver for the Osram red if the 7135 driver worked perfectly fine?

L21B osram red using the 2.5v driver

Fairly certain it was used because most other red lights only use a low, high, and beacon

It is actually quite difficult to visually tell the difference between 20% and 100% modes.

We’re running parts way out of their specs in torches daily, Eg overdriving LED’s etc

Will it break after 2000hrs of use?
Yeah, probably, because they’re running very out “burning” that much excess voltage.

Will it be less efficient?
Yeah

Those factors matter when you use torches for more than playing around like hunting, which is why Simon probably designed a dedicated step down driver with the most common modes used by hunters or similar

Yes, there’s no visual difference at all, you’re completely right…just kidding, you’re saying you can’t tell in the video?

I find them easy to distinguish. Having a lower mode than 20% would be very nice though, and significantly easier to distinguish. The 0.1% mode on my 8x7135 driver is delightfully low.

A “Moonlight” mode for the red leds would be great.

Im a bit confused about flashlights using red LED’s.
Ive been looking at a bunch recently, and it seems like most are very mode limited. Especially Convoy.
Yet Emisar/Noctigon flashlights can use red LED’s with Anduril/full range stepless ramping?

Update 1/06/22: 12 Groups Driver is currently in production and should be available within 2 weeks!

:+1:

Woohoo! Awesome!

12 group will be a good option.
