Quad 24mm Copper TPAD DTP

No i think you are right unfortunately :frowning:

This picture does not look lika a copper DTP mcpcb to me at all, if it where shouldn’t the base look copper or gold like the noctigons do?

EDIT
But then the thread title is “Quad 24mm Copper TPAD DTP” :~ ………i am so confused :~

EDIT2
I hope this is just some misunderstanding and they already had alu quads for sale, but are soon going to release a quad copper DTP version, but haven’t done that yet. And this thread where just to ask for feedback before they do just that.

Me too, and it kind of reads that way, getting an approval as it were before putting the new copper mcpcb quads online.

I’ve got quite a few of the original copper quads on hand already, so the 20mm version with 24mm optic really isn’t what interests me, and a 24mm star won’t fit a lot of smaller lights, but the 35mm Quad for a CUTE-4, that’s what I’m waiting on! (Tired of trying to align 4 individual stars)

Hmm do you mean the cutter supposed “24mm” quad is bigger than the old limited run quad copper DTP board? Or do you mean that the 24mm quad optics won’t fit a lot of smaller lights?

Agree about the 35mm CUTE-4 quad, that is really what i am most interested in :slight_smile:

The quad copper DTP 20/24mm mcpcb is just very nice to even have available on the market again, i missed out when they where available before so even if i wanted i couldn’t use one or plan a build around one.

The Quad boards I have are 20mm, it’s the optics that are 24mm. Typically, the tube lights have a 16mm star in them but the spacer needed to take up the space left over in the exchange between reflector and optic is fitted to the 16mm emitter shelf and sits higher than the top of the pill, so the 20mm star fits ok. A 24mm star might not fit in the tube in a lot of these, depends on whether or not the spacer clears the top edge of the pill.

Look, on this A6 tube light I accepted a challenge… someone (I won’t say TK’s name) said that the triple star wont’ fit in a tube light without the spacer, so I turned the star down to fit in the 16mm shelf and then trimmed the head down to fit, instead of using a spacer to lift it up and take up the difference. I had to cut half the optic support legs off on the outside to allow the optic to sit down into the space left over, but I did manage to make it work with as little change to the host as possible. :slight_smile:

On this larger small light, the X5 sample from Krono’s group buy, I was able to actually make a copper spacer that enclosed the 20mm triple Noctigon as well as the 24mm optics, almost like a P60 drop-in. The copper sits on the emitter shelf and actually fills the bezel all the way to the glass lens, acting to also hold it in place.

As with the tube light, the emitter shelf on this one is for a 16mm mcpcb, a 20 won’t quite fit, but a spacer would be made to fit into the shelf and then fill the head such that a 24mm mcpcb would actually fit (maybe, I should check the opening in the pill area, it might not take 24mm. Ahh, it won’t, it’s 22.2mm with the quad sitting almost flush with the top of the pill, so it’d have to be fitted or the pill would have to be enlarged at the top.)

I’m after 20 and 35mm copper quads

Nice pics, thanks :slight_smile: someday i want to do me a shorty head shorty tube A6 triple.

But i think i will use a sanded down mcpcb or something to raise the shelf to the upper shelf so i don’t have to sand down the triple noctigon.

Ok, but i am still unsure if cutter triple “24mm” quad is a 24mm mcpcb for 24mm optics, or a 20mm mcpcb for the same 24mm optics :~

May have been less than clear on my first post. Please note on my first post this was a question about the topology of the board. The board is to be built in Dec and is not yet available, but I wanted your feedback about whether I had everything that you needed/wanted
cheers

24mm PCB's are all quad boards for Carlco 106xx optics and 20mm triple board will be for 105xx/Ledil Satu etc

Cheers

Mark

will be doing the 20mm triple and 24mm quad together

what optics would you use with 35mm board?

Cheers

MArk

correct

ok got it, so what drive options on a 35mm Quad?

Cheers

Mark

This is our standard 32mm quad, so what drive options

parallel?

2s2p?

all in series?

which optics?

I think we all are looking to use CUTE-4 optics on a 35mm quad and most will probably use one of the many now available FET drivers for them and run them in parallel. I guess you could use the LD-2 also or just any other linear driver if you are not looking for max output.

Agree with pyro1son, that it is really a 20mm quad that would be more interesting. + we already have access to 20mm noctigon triple mcpcb’s.
It is the 20mm quad that is unavailable, but i guess one could maybe sand down a 24mm to 20mm but it is a hassle to do.

I use parallel as most of my quad builds are in the Eagle Eye X6 format, which is a single cell light. The 35mm head works great with the CUTE-4 and CUTE-3 optics from Ledil.

I think the nominal mcpcb size is 32mm in the ones I’ve been using, and even those have to be filed down a bit to make the 31.7mm inside diameter of the pill in that light. Of course, there are bigger lights and bigger options, I’ve got a 50mm triple optic that I’d like to use in a Convoy L2, not sure what would fit that.

I wonder if a triple MT-G2 board would be feasible? Or triple XHP-70? Probably with the 50mm optics, as these big boys would prefer larger individual TIR’s inside the optics. I’ve got a BTU Shocker running 3 of your 9V MT-G2 emitters at about 10,000 lumens, absolutely love this light! (triple reflector works perfectly with the big MT-G2’s)

Gotta be tough designing these as we all expect different things, use different lights, have different styles.

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. :slight_smile: 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

Cheers

Mark

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

Cheers
