ETA on Emisar D4?

Mine gets in tomorrow ;D

So if i’m reading that thing right, I can turn on mode memory in ramping?

Unfortunately not. The D4 does NOT use Narsil. It uses its own special firmware that is similar to and or based on Narsil. The D4 does NOT have memory.

Go back a few posts and read ToyKeepers post.

Any plans to restock the 32mm T-Pad triple XML DTP MCPCBs? I want to try a triple XHP50.2 C8.

Not sure exactly when they will come. Hopefully soon.

Nope. I am not going to be buying any more products from Cutter. After what happened with several of my closest BLF friends and me personally I am through. I am not going to get into the details, but I am choosing not to do business with them.

I need to do a final look and make sure I don't have any hanging around anywhere, but I am not purchasing more.

Unfortunate to hear, but I do understand. Best way to show approval or not of a company’s business practices is to vote with your wallet. Which is coincidentally why I keep coming back to MTN.

If that’s the case, any plans to build your own 32mm XML triple, now that you have a manufacturer for copper MCPCBs with your quad boards? Personally I wouldn’t mind seeing all MTN branded MCPCBs in the future, your quad board is the best I’ve seen.

If you do happen to find more of the T-Pad boards laying around, I’ll take a couple of them.

Richard is there such thing as as triple XHP70? Does Carlco make optics for this kind of thing?

I feel like I’d pay a lot of money for an L6 with three XHP70(.2)’s on a few pounds of copper, the 30mm FET+7135 Driver - 2S Momentary - Convoy L6 and an optic… kind of like a really big S2 triple.

Know anything about that?

I don’t believe that has been done before, but I see no reason it couldn’t be done if a suitable optic is found.

Kaidomain sells some 50mm triple optics which are the biggest I have found. An XHP70 dome would likely fit in them. I happened to order one today to experiment with a triple D-cell maglite, so I will report back in a few weeks when it arrives.

I know something about it. 3 lbs of copper under 3 50.2’s still allows it to get hot pretty fast. 12,000 lumens does that. Khatod makes an optic that will fit over the XHP-50.2, so if you can get the mcpcb under them you’ll be seeing 10,000 lumens and then some from a C8 using a pair of dark purple Efest 18350’s. The Aspire cells will last a bit longer but not produce quite the lumens. An extension tube with 18650’s will do something like 14,000 lumens, and this is just the 50.2. But of course, heat is a big factor and for most people the weight is also more than they care to deal with.

Going big brings in heat problems like a big dog, so without active cooling even several pounds of copper isn’t really sufficient.

What khatod optic did you use in that C8? I was going to do my triple 50.2 C8 with a Ledil CUTE-3-SS and shaved domes, but if I can avoid shaving the dome that’s even better.

I didn’t make a C8, yet, but I made an X6. Still a 35mm optic, will have to find the number on it again…. I had that one here for a few years before using it.

Pretty fun, 10,000 lumens in a X6! :smiley: Not all that practical, even with a taller copper sink (the Khatod is shorter than the CUTE-3)

Edit: the part number is Khatod PL605A06

i mean it wouldn’t have to be on direct drive all the time right (I know that’s a tough concept hahahah)

but maybe it could do 8k lumens for an hour and still be… able to be held by hand.

Lumens, big ones, and run times…. difficult to combine the two. Cells die, takes a lot of current to get the output. I tested my TR-J20 with 4 of the 9V MT-G2 emitters on level 4 of 7, looking to see how long it would stay above 4,000 lumens. I think it ran like 36 minutes, pulling down the 3 big 6000mAh 32650’s even at half what you’re asking. I’ve got it heat sinked in a big way, so heat was there but not quite a problem. More, like the next level, and it probably would have gotten too hot to touch.

RMM, do you know if your quad MCPCB fits the D4 and the D4 optic? If so, I’d like to list it as an upgrade option.

You’d get a better beam profile from Richards MCPCB if it fits, due to the skewed footprints. :wink:

Yes, it does. The D4 optic is a normal Carclo 10621 lens, unlike a lot of the other Chinese quads.

Sorry, no plans for a triple 32mm XM MCPCB. To make it cost efficient, you really need to produce hundreds---if not a thousand. I've only sold a few dozen in a year and a half.

Noticed that HaikeLite has made mention of your company as U.S.A. dealer and wondering how soon you’ll have any stock and any idea of what models.
