I am having a batch of solid copper heat sinks made for use with Cree MT-G2 in a Maglite. These sinks will be machined/milled from solid 1-1/2" Tellurium copper rod.
Here is an aluminum copper hybrid one I had made before. This picture is just for reference, so you can see what it looks like, the batch for sale will be solid copper NO aluminum.
As you can see there is a milled pocket to assist with centering the LED.
The pedistal is .500 tall for a variety of reasons.
1. Most important is that the emitter can be reflow SOLDERED DIRECTLY TO THE SINK and you can still then get you soldering iron under it to solder on the wires.
2. The added height makes it possible to use this with large deep reflectors that have been bored to 16mm like the Fivemega throwmaster and the 3" heads. This will reach the emitter high enough to get full focus.
Here is what it looks like in a thowmaster head.
The only other variance in the sinks from the one in the picture besides being of solid copper and not a hybrid is there will NOT be a set screw in the sink, they be a snug but not tight fit in a mag neck and a dab of epoxy will be needed to secure them.
Using this direct bond system you can easily push the MT-G2 emitter to a full 6000ma with a 6V led. That is DOUBLE what they are rated for. That is the equivalent of FOUR XM-L2 emitters worth of current in ONE SINGLE DIE!!!!!
Literally THOUSANDS of lumens from a single emitter. With this we are nearly creeping up on incan bulb capability.

Please post your order here followed by immediate payment. If you have not paid when the order is placed you will NOT be getting any heat sinks. I will be holding the thread open for ONE WEEK before ordering the batch!
Please also MAKE A NOTE IN PAYPAL. Please leave your BLF handle and how many sinks you want. <----- This is important so please don't forget.
To the uninitiated could you clarify which maglight these are suitable for, is this a drop-in + driver sort of thing, do you retain focusing, how does the heat pass outward onto the shell? I have a few other questions but well I don’t know what they are yet!
These are a DIY part meaning you will have to put the emitter and driver in yourself.
They fit any of the newer D cell maglite tubes.
The heat is transferred to the body from the sink to the neck of the light.
Yes the light will still be focusable. The sink can slide up and down inside the neck for use with various size heads, and focus is changed by threading the head up and down. For a standard mag reflector focus will be near the base of the reflector and for the big heads made for incan use its been my experience that they typically focus up higher in the head ( hence the longer pedestal).
@ nightspy: What do you mean ridiculed? Several members had done it long time before that graphic was posted. Match, O-L, 18sixfifty, IaA4wheeler and yours truly comes to mind just off the top of my head. It is just that it is a helluva lot of trouble for... nothing really when we can now buy sinkpads and noctigons and whatnot. No offence meant. Just maybe I don't get what you are driving at here. Match has a build here that predates that post by some 2 years with that exact idea carried out. Just saying.
Since I'm the only person in this thread that posted here before the above quote and also posted in your linked thread, I guess you're referring to me. If I made you feel ridiculed, I truly apologize. I felt you had a good concept and asked good questions that we do not yet know the answers to yet. If you look at my MT-G2 builds, you will see they are all direct mounts similar to your concept and VOB's product here. So I'm walking the walk, not just talking the talk.
I mounted them direct mostly to get the emitters higher into the reflector for focus purposes. I hoped that there would also be a thermal benefit. As I said in your thread, I don't think enough testing has been done to determine if that is the case or not.
VOB's product here provides a pedestal which can be very handy in a Mag build. The material he is using sure sounds like a good material for tall pedestal situation.
I don't see any conflict from what I said in your thread and what I have said here. If there is, I certainly didn't intend it and again apologize if I said anything to make you feel ridiculed. You're clearly a bright guy and I have nothing but respect for you.
I certainly didn’t single you out either, 4 wlr… the overall tone of the thread turned pretty much “why?”, and I just thought it interesting that someone went to the trouble to show why. Most prominent is the fact that the wires remain below the emitter which has been a significant discussion topic on a lot of Noctigon threads where reflectors were problematic with the wire pad location.
