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

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.

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?
