He if we can get triple XML/XHP50 on 20mm, we can do most things but optics define this
yes our quad is 32mm. triple MTG2, what optic would you use?
Triple xhp70 sounds possible, but need to lock an optic down
Cheers

20mm quad, parallel?
Yes parallel, i don’t think it exist any serial high amp capable driver for single cells, so i have only seen parallel use around here.
Maybe Dale can show an picture of the old limited run copper DTP 20mm mcpcb’s for reference.
I don’t even remember what they was called either, only that some russian guy showed up here and said he was doing a batch of them, and now they have been sold out for months and as far as i know there haven’t been any talk of them returning to market.
I can adapt, I’ll use whatever optics fit the board and shave the dome off of MT-G2’s so they’ll fit under the optic. Obviously, gotta have copper under triple 6V emitters, I’d try pushing all the current possible, I run 12A+ to a single MT-G2 now…
yes I think I recall seeing them. I did not realise they were 20mm. I will review with our design team next week and advise

ok will look at it next week and see what makes sense

The russian guy is BLF-member Dsche, he's still around, and actually his 20mm copper parallel quad board was still available until not so long ago, I bought a few boards from him. Here are a few pictures (the cuts in the solder pads were my doing, making the leds individually adressable):
A picture from his thread ( https://budgetlightforum.com/t/-/22412 ) :
Thanks djozz for filling in the blanks
Latest update
1. To Suit Quad lens round 24mm,
2. for 4 LEDs 3.5mm square,
3. MCPCB 20mm round (19,9mm ~ 20,1mm), 1.5mm thickness
4. Copper core with direct thermal path to the thermal pads of the LEDs,
5. LEDs to configure in parallel or 2 serial 2 parallel. 4 serial not
neccessary.
How does that look?
Cheers

Sounds perfect, thank you.
That would be great!
Sound brilliant
Sound good
But what sounds even better is that you are responsive and trying to fill the last few holes & give us the tools we need, to get even more & easier performance in our future mods
Not a problem, I want to make things people want, anything else does not make sense
Cheers
Make the traces as wide as possible. For some silly reason SinkPad made the xhp70 traces dinky. Check out those on any Noctogon. Only the copper necessary for trace separation is removed on their triples and the singles have nice wide traces.
Yes we use wide trace but also 3 oz thick for plenty of capacity
Cheers

Sweet.
...and make the center hole wider than Dsche did. I admit that I got into trouble by modding the board for four individually addressable leds (5 wires, I had to ream the hole quite a bit) but if it has no disadvantage, it is nice to have it wider in the first place.
Agreed, the 3oz traces are perfect and a larger center hole would be super nice. I always bore out the hole so I can use 18ga wire leads.
Any updates?
