I have been wanting to build one of these for about a year now.
I found this http://www.dealextreme.com/p/6-cree-...max-65153#open full view 6 Cree 1200 Lumen drop-in module from DX. (Has anyone else used one of these drop-ins?)
I had to do some machining with our lathe to make everything fit nicely.
I also turned off the stock light post in the Mag with the lathe. (I liked this better than using a hack-saw.)
Then I got two 3AA to D cell battery adapters from KD.
I also machined my own bezel from steel. It's solid as a rock, it would work great for a club...
I added some glow dots to it. (looks very cool in the dark)
It is VERY bright compared to my aspheric Mag I modded last summer. (I am considering upgrading the led to an aspheric-friendly LED, If anyone has suggestions as to which led works great for aspherics, please let me know.)
Here is just a shot comparing the two.
I will try to go get some pics of beamshots soon. Let me know what you think!
