I have been playing with another 2AA Maglite (Incan). It's becoming a 3AAA and it's finished enough to see what it looks like in the dark. Here's a quick beam shot.
XM-L T4 with 3AAA Direct Drive. I will give all the details and plenty of photos here in a day or so. I just wanted to give y'all a teaser.

Ok, I had already worked on this light some and I decided to get it done during the cooler night temps. I will cover a little of it. This was a 2AA Incan and I made it into a 3AAA LED. It has a home made heatsink, T4 Cree LED, plastic reflector & lens, copper insert to lengthen the body.
Here's some photos.
The heatsink is made from a 1/2" copper end cap, cut down to about 10mm high. Then it was filled with scrap copper pieces and solder. A piece of 020" copper flat went on the bottom. I used my rotary tool to open up the head and it's a tight enough fit, to need a rubber mallet and a socket to drive the heatsink home. Good contact for heat transfer.
The LED/Star is AA'd in place.
On the bottom side, I made a small contact and soldered the Pos wire to it. It is spaced from the heatsink with a couple of plastic washers. The Neg wire is soldered directly into the heatsink. The outer copper touches the body to make contact. (Inspiration Taken From Match's Maglite Mod).
I had to remove quite a bit of the already tiny reflector. Not very much room in one of these AA Mags. Less room for my fingers... Ouch!
In order to keep the 3AAA batteries centered, I made a sleeve. Nothing was close to fitting. I ended up using a piece of 1/2" PVC pipe and I had to split it and cut a slice out the length, so it would close up enough to slide into the body. Then it was too small of an ID for the AAA batteries, so I had to hold it closed in a vise and drill out the center, to accomodate the batts. Too much work for a simple job.
Of course the human lathe method was used to fit a piecs of 1/2" TypeM copper pipe and a copper coupling, to make the insert in the body. Paint covered it up ok.
And there it is. Finished and very bright with direct drive, 3AAA eneloops and an XM-L T4.
Couple of beam shots. This thing gets hot fast! Both the battereis and the head/heatsink, heat up very quickly. It's just a fast food hot pocket light. Not meant for anything but, WOW.
I decided not to do any cosmetic mods. A guy at work wants to buy the next 3-4 lights I make, if they are small and bright, so it's probably gone tonight.
