Ok, I grabbed THIS at my local home depot a few weeks ago. A two pack for nine bucks, hoping they might make decent host. After dissasembly, it wasn't promising.

Then i got three fasttech modules. I was wanting to put them in something simple, mainly to use it easily. Then i happened to think of these flashlights.
So I took one of the modules and slid it into a black anodized aluminum heatsink. Then I opened the flashlight back up and removed the large plastic retainer that held the LEDs and driver board. I removed the guts from the retainer, and slid the module in. The heatsink stopped the module just right for the button to line up. :)

Over the last few days, as a little side project, i got this working. I put a gob of tape in the back of the plastic insert to help support driver/module. I used more tape to get a snug fit for the HS. While doing this, the neg wire came off, which was fine for my plan. I cut the positive just short enough to go through the hole in the retainer, and striped about a 1/4in of insulation. Then i unsoldered the metal contact from the LED board and soldered it to the negative of driver, making this a positive ground.

Here is both. The black is still normal, the silver laserfied. :D

Pre final assembly. The 3xAAA holder is the modified one from my first build. I used two AAA alkaline batteries, but had to put them in upside down.

I taped the positive so it would make contact with host, then slid it in and screwed the top on. It's not perpectly aligned, but it works. :wave:

For something that was thrown together, i thing it's pretty nice.

Well let me tell you I like your build quite a bit... You got yourself a nice laser and at a very reasonable price... that is good.
Congratulations.
