This MCPCB is “common anode” type, which makes it suitable for LEDs with common anode (infrared OSLON like SFH 4715AS and LUXEON IR), but LEDs with common cathode (OSLON BLACK FLAT for ex.) can be also used – LED should be soldered in opposite direction, “+” and “-” solder pads are also inverted in that case.
Also, I added two white spacers for ILC-0 under ILC-0 options, one 18x2mm for Convoy and equivalent lights, other 17x2mm for Eagle Eye X6:
White spacers give very uniform brightness across whole tailcap surface. 17x2mm white spacer is first spacer available for Eagle Eye X6, so build is now easy.
Just wanted to report that my ILC-0 from recent giveaway arrived several days ago, unfortunately I was so busy this days I did not have a time to try it out
I did take it with me to workplace thinking that Nikon D3200 that we use for work will give me some nice photos, well it turned out that D3200 with kit lens makes shitiest, unusable macro photos I ever saw.
So THANKS led4power, this is the fanciest lighted switch I now own
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.
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.
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
