【convoy】H4 and B35AM options are updated

Any chance for 15mm diameter driver?
It’s very rare.

Suggested mode:

- L - M - H

  • H - M - L

No memory, no strobe (or hidden).

With the S2+ and C8+ the first thing I did is to set memory mode :slight_smile:
One thing is sure: most important is to ramp from low to high, and make hard to initiate strobe.

Anyway, is it that hard to implement a memory mode in these drivers, what the user can turn on or off? It looks like it was not a problem with the Attiny.

Is the current of these drivers limited per firmware or are this direct drive drivers?
Will I get 10-18Amps with a 3V XHP50.2? Is this possible?

Since I joined BLF, there is discussion about memory/no memory, and no one will convince the other.

So yes please, mode order low->high, and option to switch memory on/off. I like the classic way to do that: after 5 seconds in lowest mode a quick off-on blink shows, then click to toggle memory on/off.

Please don’t do the blinky stuff! :sunglasses: I have changed the driver in my S2+ lamps because of that blink in low mode :smiley: The “click an insane amount to go to settings” is way better I think.


Amen! :))


Toykeepers Bistro/Biscotti buzzing after 10 clicks would be way better than that utterly annoying blink after 5s on low mode, literally everyone hates it and it’s a medieval solution.


  • FF (0.5lm or less)>Low>Medium>High (looped)
  • Instant mode memory with no waiting for two hours for the driver to activate it
  • double press to go back one mode or long press to go to the first mode

optionally Biscotti style programing after 10 half presses to reverse the mode order to H>M>L>FF and to turn off or on the Mode memory.

This way everyone would be happy, it will stay muggle friendly and the implementation shouldn’t be a challenge.

Yep, Bistro UI. Strobe is hidden, memory and moonlight can be enabled/disabled, number of modes and modes order (low to high, high to low) can be changed, etc.
It’s better to have an UI that is configurable by the user than changing convoy UI each time someone request a varation that can be changed with a programmable UI.

I did not know that the blib on low mode for mode group changing was so thoroughly hated among BLF :party:
Ok Simon, please do not do that but listen to the other suggestions :slight_smile:

I will be OK with any set of 4-6 modes of constant light (strobe is not mandatory; moonlight is).
What I’m looking for is versatile power supply (everything of AA form factor can be used: alkaline, NiMH, Li-Ion,…) and size.
Such a one-cell flashlight should be most compact, allowing even holding on keyring for an ideal case.
Two-cell option will be comfortable for self-defence purposes because of diameter/length combination (but need no tail button here).

I think you are trying to PM me via Ali Express, but that may be another matter. It’s not connecting to AliExpress right now so will Reply to that later.

Thanks Simon!

Apart from the 4-6 modes, there is something like that, the DQG Slim Ti: “REVIEW”: DQG Slim Ti (1/2 AA and other batteries) ***[DISCOUNT CODE ADDED - 05/22/2018]***


I didn’t buy S2+ because of blinking in low mode. No more blinking :weary:

5 modes ML-Lo-Lo-Med-Hi with 2-click for back

And ability to turn memory on and off after a bunch of clicks, strobe after…idk

My personal best is 2 mode groups, 4 modes in each and memory on in one, and off in another, group changing after 9-click. E.g. 1–10–40–100 memory on and 0,2–3–15–60 memory off

uh,15mm is too small

the ramping driver is direct driver
the 4modes has constant current

uh ,you can PM me about your problem

I posted them HERE.

The ramping driver is regulated. Comes stock configured at 8A in high, using a 5mΩ (R005) sense resistor (I recently built a C8S with a ∅22mm unit and got 7.63A measured with my power supply for that unit). Being regulated means it uses the MOSFET in linear mode by tuning the gate voltage to limit current to desired values, thus it won't go above 8A unless the sense resistor value is lowered.

Better to say this than having to hear someone complaining at a later date. Wieselflinkpro is probably better served with an unregulated MOSFET driver (with @#$% PWMed mid and low modes) if he wants as much current as it will go.


Does anyone know if the S2+ clip will fit the S21 correctly?
