Led4power.com : LD-4 CC linear drivers, ILC-0/1 illuminated tailcaps, optics, MOSX, copper DTP MCPCBs...

Thanks for the clearance boards! I just bought a few yesterday. I wish I could have bought more but I’ve been spending a lot on other things already this year. I also bought another Q8 4040/5050 board, and it made me wonder if you ever sold enough to break even on those. You had said before that a lot of people who showed interest never bought any of them, and you were stuck with a lot of unsold boards. I know that was before I had bought any, and I’ve bought a couple of them since then. So, I’m hoping others have stepped up too, and you don’t lose money.

I think the 3V XHP50.2 may have spurred some sales. 15K lumen Q8’s

Or more… 17000lm

Possibly even more “IF” you buy a bunch of 50.2 3v and cherry pick’em….over 5000lm with out lens.

4800lm with a UCL lens from flashlightlens.com

Wish I had 3 more of these…. :cry:

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.

5700K Luxeon V (I'll put it on web this weekend).

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

Neven, any plans to be able to utilize an electronic side switch ?

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.

Kaidomain sells adapters.

Thank you!

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 agree, they are way too thick

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?

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.
