For 6V LED?
1S-4S, PCB prepared for e-sw support also, but first it will be clicky switch only.
Neat. Could the LD-4B be used in theory with 4 separate MOSLED PCBs in something like the Q8, so each emitter has it’s own MOSFET, or would that cause issues on the gate drive? Honestly I’ve never really tested to see how consistent MOSFETs are part to part.
Really liking the new PCBs though, going to have to pick up some 4040 triples and quads at least, likely some others as well to go with the LD-B4HV once it is live. Will there be an LD-A4HV at any point?
Mosfets like many semiconductor parts have relatively wide tolerances, so separate mosfets with only one control signal is not best idea,at least in theory (just like parallel LED connection is not recommended), but it may work. Better solution would be one big mosfet (can be on separate PCB if there is enough space) and LEDs in parallel. For example, in Q8 you could use normal copper DTP board(s) for LEDs and have mosfet on its own mcpcb mounted on bottom side of the shelf (glue,screws...), all controlled with one LD-B4(HV).
For Luxeon V triples and quads you can use existing LD-B4,if you have clicky hosts of course. There will be no LD-A4HV because even on single cell, heat management is not easy with most new low Vf LEDs; dissipation in mosfet with most of 6V-12V LEDs is over what mosfet mounted on FR4 pcb could handle.
Hey, good news you’ll make e-switch drivers again. :+1:
I had a bit of time to play with the MosX 20mm MCPCB and the LUXEON V emitter.
First I tried it in a EE X6 with a BLF A6 driver, I got 8.56 A draw on turbo but I couldn’t find a centering I thought fitted properly.
I ended up with a Sofirn C8 host and a MTN-17DDm driver giving 9.31 A draw on turbo
I used one of these Convoy centering rings reamed out to fit the emitter
The think the MCPCB’s are great, but it does take a lot more heat to solder the wires. The amp draw is very high so I will be ordering a LD-B4 6Amp driver and a ILC-0 Illuminated tailcap.
Waiting for these driver, finally… 
:sunglasses:

Maybe next year 
About when next year? :+1:
Neven I’m down to (3) LD-2 M2’s ( one of which is going into one of two BLF GT’s) and (3) LD-2’s I have been saving as back ups, stop torturing us/me!
Clicky version very soon, e-switch after that.
When will you have the Luxeon V on 16mm board back in stock?
Im wanting to build a new EDC light for the coming year with LD-A4, ILC-1, thermal kit for S2+, and Luxeon V. Everything is my cart but the Luxeon
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.
