One more qiestion: is there a difference between direct drive LD-A4 4-6 amp version versus DD on 7-9 amp version of the same driver? Is the FET the same?
What happens if for example I use battery that can give 5 amp max and I set it to 6 amps regulated?
Thanks!

There is no difference between DD mode on 3-12Amp versions, it's "real" DD which means fet is fully turned on.

If battery can provide 5A max. and you have 6A max. mode, it will act like DD mode - driver will provide max. possible current.

5700K Luxeon V added, all multiple LED MCPCBs have 4000K/5700K tint mixing option:

Also I added "Do not solder FET+NTC+connector" option for big (32mm and 34mm) mosX boards - for those who want to use those boards with any other driver except LD-B4.

Osram KW CSLNM1.TG (1mm2 "white flat") is back in stock (same good bin 6N-ebxD46), with lower price:

Wow, very interesting and low priced!
might have to buy some soon.

The white flat is just a 3V LED isn’t it?

Yes, 3V single die.

Hi Neven,

Would it be possible to release drivers in the future with other firmwares such as Crescendo or Bistro? Maybe charge an extra fee for that??

I have tried both, and especially Crescendo would be awesome on your drivers.

Those firmwares are made for DD drivers and are not compatible in any way with my drivers, and vice versa. Future compatibility is also not possible, drivers which use them don't have (IHMO) basic hardware requirements like current regulation and external temp. sensor support.

Are your drivers open source?

No.

:smiley: Hahaa NO. with a period! :beer:

Haha couldn’t hurt to ask :slight_smile:

Post #1000!

(at the moment)

Any way of mode ascending, either by double click or TK style long click would be very welcome.

That and much more will be available on next driver generation.

Osram 4040 1mm2 LED CULNM1.TG added,limited qty available:

CULNM1.TG

Electronic Side switch availability I hope ?

Of course.

Looking forward to the next generation drivers then.

Are you still planning on making 20mm drivers? I am concerned about the heat transfer from the Mosfet on the LD-A4 driver when using adaptor rings even though I fill the driver cavity with silicone cubes. I use my throwers with two modes only, moonlight and max safe regulated current. This means the mosfet won’t run too hot in high mode because of the difference between Vbatt and Vf at those high currents, right? I am referring to the CSLNM1.TG and when I install the new CULNM1.TG.
