Yes, there is checkbox for that option (no FET and NTC) for 32/34mm MZ boards, I added this too for 3xMZ 20mm board:

You don't need to use jumper on 20mm mosX boards, you can solder wire directly to FET big pad:

Also one note, LEDs and optics are not available in “bare” form due to some business reasons, you can still (technically) buy bare LEDs by purchasing 16 or 20mm DTP PCBs and checking “Don’t solder LED” box. You will need to buy DTP PCB of course, but most of them is on clearance sale anyway, so price is good. You can also buy optics together with compatible MCPCBs, there is checkbox “add xxx optics” option.
Why? I had 10 luxeon v2 in the basket without mcpcbs. I would like to buy them without mcpcb because I don’t need them and they inflate the price. If we can buy leds without soldering, why can’t you buy leds separately, without mcpcbs? If you don’t want to change it, could you at least add the “Don’t solder LED” option to triples and quads?
Bureaucracy reasons, my start-up company is not registered for trade (re-selling), so I’m technically allowed to sell only my own products. “My own products” could be basically any new product that’s different from input raw material. So LED + MCPCB (soldered or not) is new product, LED alone is not new product. To get trade registration in my country you need to have >50m2 (expensive) separate warehouse no matter if you are selling 0402 resistors(and your whole stock can fit in your backpack), or cars. There was one case where inspection closed e-book store (yes, digital downloadable books) because owner did not have 50m2 warehouse for e-books LOL.
I added “don’t solder LEDs and NTC” to for 20mm quad CuDTP:

xD
Is Luxeon V 4000k unavailable? I can’t find a quad. There is only 5700k

It's out of stock, currently I have only 5700K.

I see that you have all non-IR alu MCPCBs on a sale. Does this mean that you want to switch to copper where it’s a good fit or that you have newer variants in the queue?

I plan to have new 16 and 20mm DTP boards in 3030,3535 and 4040 footprint format,and possibly 3x,4x 20mm 3030,I'm not sure about the rest, demand is too low.

Sretna Nova!
I’ve been looking for triple 3030 20mm MCPCB’s for a ling time now

Sounds like you need to add a new product - a 30mm x 120 mm strip of bare copper. Label it “LED test fixture, holds up to 12 LEDS” and have a “Do Not Solder LEDS to test fixture” option

Neven,
Glad things are up and running again and I hope you have a good year. I’m very interested in either 3x or 4x (preferably the latter though) 20mm DTP MCPB in 3030 footprint. I need some other things and I’m debating about whether I should wait to order until these boards come out. Do you have a rough estimate on when they might be ready? Thanks.

3x and 4x 3030 will come after new 16 and 20mm boards, so not fast, maybe in March (the main reason is I'm searching for new reliable supplier, last one went into full Chinese mode and just suddenly closed his company and send me only half of my boards -> 1000$+ damage,and delay with new boards release is the consequence).
Hi Neven! Happy New Year!
Any estimated date for the Luxeon V 4000K restock?
I was really counting on them for my OL Contest mod :cry:

On which board? Maybe I have few pcs on other PCBs.

Hi Neven! Thanks for the reply!
I want(ed) a 4 x Luxeon 4000K on the respective 20mm board for a quad build! No wires soldered!

No FET+NTC, just 4xLEDs on 20mm 4xV mosX?
Yup, precisely that!
I will use a driver from Lexel!
Do you have any ? If so, please PM!
Thanks in advance!

Anyone know if these will work with a sofirn c8?
