****Copper Eagle Eye X6 heatsinks****(design)

Quad optics are much much smaller than the triple optics, so by the very design the Quad isn’t going to throw or have the beam profile of the larger optics. The Quad individual TIR’s are ~10mm x 5.8mm approx, while the triple CUTE-3 SS has TIR’s at 17.4mm x 13.7mm. Much larger.

For me, the very size of the X6 is the reason to use a quad in it, potential for massive heat sinking to handle the heat of 4 emitters. The quad deal is a limited thing anyway, with less than 40 quad boards still available from Richard. Without those boards, it’s DIW.

I talked Hank at Intl-Outdoor into producing more of the 32mm Noctigons, he was out of stock and wasn’t planning on re-stocking. As of last night he had 168 in stock. So that too might be a limited deal, just with more available at the moment.

Richards plan is being held up at the moment by some odd dealings with his host supplier. Since there’s no good idea of when that might be rectified…

Yes, I’m doing what I can to help Richard get set up and running with this same kind of deal. The machinist we’re working with is behind and the hosts are temporarily shelved. With the Group Buy being over 800 lights, and not knowing how many of those might want a modification, there’s more than likely plenty of room for more than one to be working on this. Richard will have the complete set-up, with host, emitters, proper boards and optics as well as the spacers in the triple category. So those will be available to all that are interested and the Special Edition lights won’t have anything to do with it, they can be left as they shipped in their pretty little SE boxes. :wink:

Yes, but can you make your quad make significantly more light, and can it run significantly more efficiently with the same light output, thats what I’m primarily interested in :slight_smile: I like the X6 for bigger head and better fins/heat dissipation as well, and I thought the “advantage” to the quad was that we wouldn’t have to run as much current to get the same light, it would be more efficient and max lumens would be perceptibly a bit brighter…but is that the case?

Nitro, yes, your picture

is what I think I read someone describe, in one of the other topics.
I hope someone who knows will speak up, if there are any important variations in the actual flashlight body

i have both and i think they are the same, i dont want to take measurements from the non BLF x6 BC the head does not screw all the way down.

I was thinking along those lines myself, that a quad could make the same light more efficiently but I’m not finding that to be the case. I built a quad in a different light and it’s full blown all out pedal to the metal at 15.10A. It’ll do 4416 at start, 3743 at 30 seconds. And makes a great heater!

In my Triple X6 with aluminum sink, I’m seeing a current draw of 12.57A and output at 3788 at start from the next bin down…XP-L V5 2D. So the output is comparable with significantly less current draw in the Triple. The larger optics are making the difference and I’m thinking the better thermal path keeps it cooler for the long run. Might pan out to be similar with the big quad heat sink, don’t know yet.

So far, my measurements on the Eagle Eye X6 internally match the Special Edition light. I’ve had about 15 of these lights in hand and the only difference I’m aware of is the tail cap is stretched to allow the boot to be inside the dimensions for tail standing. Internally they’re the same in my findings.

just posting to check to see if everyone likes the design and if they would change anything or any additional ideas ? if not its going to be machined as the 2 pics i posted :)

Great to see this is going forward

few machinist i had talked to said would it be ok to use C145 Tellurium Copper besides C110 what do u guys think on that ?

Given the smaller size of the quad board it would be more likely to benefit from copper than the larger board but not sure if it’s worth the extra weight. I’m just getting the lower piece in aluminum anyway so don’t count this as a vote, just my .02.

As long as we’re talking about cutting back… To me it seems that disks would be fine. Eliminate the post coming out of the bottom and you eliminate another machining operation = lower cost…

Thermal conductivity seen here. How do you convert to W/(m K) in order to compare with Engineering Toolbox? I’d like to see how this Tellurium Copper compares to “regular” Copper and Aluminum.

Edit: I found this to convert. W/(m K) of Tellurium Copper is 354.8 and Engineering Toolbox has Copper at 401 and Aluminum at 205.

I was thinking of having the quad done in aluminum and the triple in copper, i hate to remove the bottom post of the triple because that would be loosing a place to reduce heat transfer through the host

i no the Quad is around $10 each and i have to get a quote on some copper rod should be around the same price or just a hair more due to being more $$$ than aluminum but will find out ASAP...........Edit: The price also reflects on quantity more interest the better and should be cheaper

Please don’t make any compromises for the sake of a few dollars. If it doesn’t get done correctly there is no point doing it at all in my opinion. I always go by the motto “do it once do it right”.

Your current design in copper looks spot on to me.

I agree with LSX. We got the lights at such a heck of a price. No need to skimp here! lol Nothing like buying a $20 light and dropping $75 in mods! :money_mouth_face: :davie:

How about some slots for Tritium while your at it??

I like the idea of a copper 2 piece on this build. But a one piece would be nice as well. Thanks for the handy work guys. I am looking forward to some sample pics so I can wrap my peabrain around it. :Sp This light is the perfect platform.

Ricflair i wish there was room for Tritium slots :) but if u wanted u can cut slots into the optic for them ?

Gonna have to add interest in a copper triple. So that’s one each in copper, would accept the quad in aluminum if supply is too low or copper isn’t made in this one.

And there’s plenty of room in the surround on the quad for trits, as many as you want to purchase. With that ~1/4” surrounding the optic, merely drilling holes for vertical mount would work fine. Slot could be milled for laying them down.

How well do the trit vials tolerate heat?

If im right i think u guys wanted aluminum on the quad ? and copper for the triple.?

If so that would keep cost WAY down

the aluminum quad will be $10 for 50 pcs <<witch is no problem

the copper triple should be around the same if not a tad more due to copper being pricey, once i get both made ill be posting another thread about the samples and pictures on how they look and inside the host and from there ill be writing on who wants what ect.......

just guessing of the top of my head if u wanted copper quads it would be high $20's and i think that's high for a budget light ?

I would pay $20 for a copper quad. I know what it took me to make the aluminum one, $20 would be great in copper if indeed you can get one made for that. Definitely want a triple in copper.

And I’d rather have pure oxygen free copper than beryllium or tellurium or any other alloy.

One thing that I think is important is that they keep tolerances tight enough that you have to push it into the host. Even tight enough you have to bang on it a little. (press fit) If I have to freeze the sink and heat the head of the light to get the 2 to mate up, that’d be awesome! Then we’d know it’s a great thermal joint and it’d almost be one piece. If it slips in too freely, opportunity will be lost.

Edit: I’d rather have to sand the anodizing out of the head and bezel of my light in order to get it to fit than have to wrap the sink with foil to make it tight, does that make sense?

yup that's what i told them, they just brought up the other type of copper because its easy to machine , cant wait till these are done :)

I really like the feel of a light with some heft to it. Copper adds a weight that makes a light feel substantial and I like that. I know a lot of people are all about how light-weight a light is, but I am the opposite of that and enjoy the heft, the solid feel. My all copper Cypreus from Sinner is a little chunk of a light and I love it for that!

The Quad has that kind of feel to it, even with 6061 aluminum used. The light just feels solid, reliable, a thumper (well, if it were bigger!) I alternate EDC between my Quad and Triple X6 lights and it’s difficult to say which is my favorite. I think I like the look of the triple, but the weight and style of the quad has a merit of it’s own that is undeniable. I polished the top face of my quad (ok, I pretty much polished the entire thing) and that mirror finished ring around the optic inside the black host is pretty cool. An anodized color would be a neat customization as well. I guess a printed color wheel could be inserted that would give the same appearance as it would be under the glass lens. It could then be changed out fairly easily. The trit idea is also cool. :wink: Gonna have to look into that, what are trits…$5-7 each? Need to look up the trit guy at marketplace…

I’ve even got the curing light for Norland now! :slight_smile:
