I built an X6 quad with LED4Power’s new spacer:

http://budgetlightforum.com/comment/1461027#comment-1461027

Thanks for all the parts Led4power. Everything arrived in good order. At first, I wasn’t completely onboard with lighted tailcaps, but they are pretty cool. They might even help me if the power goes out. One build done and more to go. Waiting on some parts.

Is the LD-B4HV going to back in stock soon? Or do you have something else planned? Also, I’m highly anticipating the release of the Subzero.
If I have something selected as being in my wishlist, will I automatically get an email once it is back in stock?

Thanks for any help.

Thanks Neven! All good as ever!

Any news on the CULPM1.TG yet?
I really want some of that boost hx

Any suggestions on what to use for a thermal path with an LD-A4 and a S2+ host?

Reading through the thread again I realized I ordered a 12A LD-A4 with the intention or using it for a triple, misunderstanding the use of a MOSFET on this style of driver and don’t have anything to use as a heatsink. It’ll be going in a kiriba-ru triple copper pill, would some of those silicon thermal cubes suffice?

DarkShot, this aluminum spacer is probably meant for such duties. You could also craft it from copper if able, or something similar. The dimensions can be easily figured out, height is the only measurement which can leave a bit of doubt but this is easily solved making the part a tiny bit taller so you can sand down reduce it if needed later.

Cheers, the issue at hand is those thermal kits are out of stock, and if they were in stock they still wouldn’t work, as I’ll need a single hole for the triple pill I intend on using. If I had some machining tools at my availability this’d be done in short order but I don’t unfortunately.

Thanks for the suggestion though!

Due to larger number of orders and some other projects that I must finish, those stuff is unfortunately postponed.

Still waiting for the FET switches and den 30A drivers :).

My order arrived yesterday! Had everything arrive extremely well packaged, and everything went together almost without a hitch!

Unfortunately it looks like the RGB LEDs don’t like heat or I otherwise ham handed something, ‘cause one of them the red channel no longer works and I managed to kill another one. This was 100% my fault, it arrived perfectly functioning. Time to source some new RGB LEDs!

Additionally, where could I add a bleed resistor to an LD-x4 that I didn’t select as an option to use an illuminated tail cap?

Any new products coming soon?

Hello Neven, is it possible that you will offer XHP50.2 in 3V variant?
Such as from cutter in around 5000K?

I just built a light using the LD-B4 driver and one of your quad pcbs. I couldn’t find a diagram showing the connections of the socket on the pcb. I had to carefully study the pictures of your example build. Is there no diagram anywhere?

I’m talking about the LED PCB. There is no diagram for it.

Edit: see LED4Power answer below

Question: mode advance in the LD-4 drivers is done by a half click, that’s pretty obvious. But is movement in the other direction possible? Eg. by a double click. I can’t find anything about this in the instruction

Double click can be assigned a special function. It’s in the instructions. No reverse

Thanks. I bought the parts used and did actually manage to switch moonlight and temp which means that the overtemp protection doesn’t work correctly. It was easy to fix though.

Here's a German thread on my build.

I build 2x Convoy S2+ few days ago (post in mod thread) but today have time to take more pictures.

Both with l4p mpcb and drivers and with custom retaining ring from kiriba-ru.

The leds are Luxeon V and Nichia 219-b-v1 sw45k 9080. I read that the nichia led become more pink at current higher than 2Amps (1,5Amps now) So, probably change the driver to LD-4 3Amp in the future

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

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….

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