Convoy M21A & S21A

I’m not sure how much interest there would be but i’d definitely get a 12A B4HV.

I imagine the A4 7-9A would be popular. (luxeon V, SST-40)

Why is the difference for the for the 9A version 2A and the 12A version 4A? would it be possible to make a 5-8A version? that’d hit the sweet spot for XPL-HI, Luxeon V , SST-20, SST40, White flat 1 and 2 and others.

I would definitely go for a 4-6 A version for Luxeon V, and 7-9 A version for 3V XHP50.2.

I tend not to overdrive my LED’s too much to keep them in regulation for longer and better efficiency.

led4power, do you know when osram white flat on 20mm board will be back in stock? Thanks!

Next week at best, I maybe have 4-5pcs in reserve, how many do you need?

I have a BLF luckysun D80 that’s been waiting forever for a correct driver, the 20mm driver would be perfect.

Hi Neven,

Is there any chance to offer Osram CSLPM1.TG (White Flat 2mm²) and CSLNM1.TG (White Flat 1mm²) on a 20mm quad MCPCB? I would be very interested into some DYI light comparable like Acebeam's TK16. Kirill (kiriba-ru) seems to be working on a quad pill for the S11 host.

Cheers,

Thomas

I have 20mm triple and quad 3030 on my "wish-to-do" list for a while, regular 3535 pcbs are just not good for that, even on single LED pcbs white flat slides to one side 50% of time during reflow.

I got exited just imagining a quad white flat in the D4.

I think it’s actually more impressive in a triple since they are driven harder or a quad with bigger optics and bigger battery like the D4S.

I’d buy two 20mm LD-B4

I need 3 for now. I will buy some more stuff from the site, how do I add this to cart? Thanks!

I added 4pcs in stock so you can add it in cart:

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.
