ETA on new boards is 3-4 weeks. I have few pieces left - added 2pcs in stock on website,so you can order.
Would it be possible to order the 3XP 4040 board with the luxeons already soldered on it? If so, please PM with information about additional costs etc.
Thanks in advance!
Please add board and leds separately,and just leave me a note in order about soldering, no extra fees.
Yeah, I just saw that… deleted my post but wasn’t fast enough 
So how does this work, for instance if you use a 4-6A driver does that mean that 4-6 is max current? How much current does the other modes have then? What's the lowest it will go to? What's the mode percentages? Would the ld-4 work with xhp50.2/70.2? aswell how about triples in parallel? For example s2+ with triple xp-g3?
The 4-6 A driver has a high mode that’s configurable over a range from 4 to 6 amps. In the programming, you can set it to be either of those values, or anywhere in between in 250mA steps.
The lower modes are then percentages of that maximum. Lowering the max lowers them all, so they stay visually linear. I’m not sure what the actual output current is for each mode.
The lowest is the “special” moonlight mode, which is independent of the others (in other words does not scale with the maximum) and is instead fixed at either 2.5mA, 5.0mA, or 7.5mA. Or you can turn it off. Its very dim.
The LD4 currently only works with 3v emitters, so no XHP-series stuff. Its great on multi-emitter setups though, as long as its 3v emitters in parallel. I’ve got them on several triples.
Well explained emarkd, thanks:)
I will just add that 6V-12V version of LD-B4 will be available soon.
So if I do a triple xp-g3 and a triple nichia 219 in s2+ what driver would you recommend how much current is good for triple parallel?
what percentage do the modes have? How many amps per mode? Depending on max current they change of course but what wouls they be in general?
The percentages for each mode are all in the datasheet, which is linked from led4power’s website. I’ll link it instead of retyping it all.
oh yeah I must read it through thank you! Btw what do you think is suitable max amps for a triple s2+? What would be best ? how far can you push it? I know it gets hot and should only use high amps in short bursts but what do you think?
9-12Amps total is what most people use for high power builds, driver should be B4 variant in combination with mosled or mosx metal core PCB.
Just for information and maybe a suggestion, have you thought about making a triple mosled board for the E21A? These leds seem like a perfect fit for LD-B4, they have a very low Vf, work well with optics, are avaiable in very interesting tints and are best driven at ~2A, which would make for 6A total max current which I find ideal for small triples. I know Clemence is already making some boards but I would prefer the more traditional/well known triple layout and I don’t think I’m the only one, though I don’t really know how much of a market there would be for something like that.
By the way, I’ve been using my triple X6 with LD-A4 and the LD-B4 E2L a lot lately and I’m really enjoying the amount of configuration options and the ease of use of the configuration menu, after memorizing the menu it becomes really easy to customize the driver on the spot depending on my needs.

Are those nichias compatible with carclo optics? They are very thin and domeless, I'm not sure they would work well with standard optics.
They are compatible for sure as there are official numbers for cd/lm and efficiency on the carclo website ( example ), and they seem more or less in line with the usual 3.45mm domed leds though efficiency looks a bit worse.
I’d guess that the focus would be a bit off, the optic should be a bit closer to the board. A bit of filing of the legs to extend the narrow bit should solve that but it does complicate the mod.
Apart from that, the attractiveness of such a board is a bit dependent on those nice offerings from Clemence, I hope that he is able to keep getting those nice leds.
That said, a triple E21A board sounds pretty cool to me.
I use those too, but i pushed a square diamond coated file through it, so you have 4 corners filed away.
Perfect fit.
Received my MosX mcpcb’s today , that was fast !
Just tried 2 of them , with 2 Oslon black flat leds (LUW HWQP) .
The reflow was really easy , pads line up exactly and you can remove excess solder easily .
I made a simple setup in a Eagle Eye X6 , with a fet driver using a PSMN3R0-30YLDX fet (not really low resistance fet) . Soldering the wires on the mcpcb is tricky , thank god i have a soldering station with variable temp .
Unfortunately the light it emmits turns blue in turbo (when in direct drive) , so i guess as djozz mentioned the thermal pad of the Oslon isn’t big enough , and the black flat can’t handle the heat on a non dtp board .
I will run some more test tomorrow and report back.
