That is beautiful work PCC.
I love the attention to detail. And the massive heatsink.
In your opinion, does the light become warmer than a XML @ 3A ??
Thank you for sharing.
I was guesstimating 750 lumens.
With regards to heat, it should be little different regardless of what the LeD configuration is because 3A is 3A.
I agree that 3A is 3A. But the more light that travels out the lens less energy is transformed into heat (in the flashlight body).
And I was thinking that maybe the evenly spread out source points of heat could perhaps lead to a better (shorter) thermal pathway to the outer side of the light thus making a difference to the perceived heat. I guess not.
But thanks for answering my question :-)
Okay, I made a bezel for it. Here are the pictures.
I chucked a big piece of aluminum in the lathe and turned it down. I then drilled a hole in the end and started boring it out. This is what it looked like after that:
I threaded it and got it to fit the flashlight:
I then trimmed it down a bit and grooved it so it didn't look like a simple sleeve. I had thought about knurling it, though I decided that a cleaner look would work better:
Either the lens is super clear, or, there's no lens there. Yeah, I still need to make a lens for it.
Nice! So this is not going to have the normal maglite head?
Nope.
So whats the cost?
The cost as in how much am I charging my friend for this or how much would I charge to have another one made? It’s a gift from me to him so it’s gratis for him. Cost to have another one done? Haven’t really given it any thought. Since this is my last 3D Mag you’ll need to supply the host or I can run out to HD/Costco/Lowe’s and buy a 3D MagLED for you and build around that. Parts alone is about $50 ($19 for the triple, $6 for the driver, $25 for the Mag). My materials cost isn’t that much so I’ll absorb it into the labor costs, which would be in the neighborhood of about $75, making it $125. Wow, I’m having second thoughts about giving this one away!
I love this concept but I am thinking about a triple xml setup
We went on a night hike last night and bigC brought this light. The good: lots of light on high with beautiful color rendition everywhere. The bad: due to the high Vf of the LEDs bigC is only getting about 1.5 hours of run time on high due to the voltage of the cells dropping below the Vf of the LEDs and the light going into direct drive. This same build with XM-Ls, because of the lower VF, would go considerably longer before the output drops. The solution? Use a 4D or sleeve the 3D for 4Cs.
Nice build, and nice machining work

Thanks, Will, coming from you that really means something.
Very well done! It reminds me of something I tried ~ year ago using the triple / carclo lens set-up...
I took the cheesy approach to the head though and just milled down the stocker... Lens retention was via a pressed in brass ring. Since I'm still pretending to know what I'm doing with a lathe I avoid having to cut threads at all costs 
I have been cutting threads for at least 5 years, and I “still” try as much as I can to avoid cutting threads as much as I can

Hi, is this parallel or in line connection of LEDs?
Its parallel.
Would you be able to produce a head just like the one shown here? If so, for how much? I’m looking for something to retain a 35mm optic mounted to a heatsink - seems like this would be the perfect approach. FYI it would be for PilotPTK’s module - As requested, 3 XM-L Driver/Emitter module DIY.
PM inbound…
It may be smart to just start a sales thread PCC, I would like one to and I'm sure others will. :D Especially if it could come prepped with a heatsink so all you have to do is solder the wires on.
Thinking about this…
