Is the LD A4 enough for the 3V XHP50.2 or should I go with the B4?

I haven’t had issues pushing 12A through the A4 in a small host.

Neven, can you perhaps put up a picture to show the tint vs the 4000K Luxeon V?

If not for shipping, that clearance would feel like a gaw. I love your alu boards.

Neven, do you offer 20mm drivers or 17mm to 20mm driver adapters?

Thanks,
Caleb

Not currently, I'll check with Simon if he could make some adapters.

Yes, but I can't tell exactly when since I have some other custom projects to do.

Those are too tall for at least the Convoy L2, i had to grind mine down to at least half for the retaining ring to fit over it.

I could possibly make small batch of 20mm LD-x4 pcbs, how much interest there would be and for which host they would be most used?

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.

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.

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:

https://led4power.com/page/1/?s=l1v1&post_type=product

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.
