Step 2: Choose a Host.

Any C8 flashlight will do, but it makes the build much easier if you get a decent quality one. I prefer the Convoy brand myself.

Step 4: Bypass the Springs!

Don't skip this step. Metal springs are very high in resistance, so solder a piece of wire in the center to create an electrical bypass. Be sure to do this on the driver board base as well as the spring that is in the tail cap. Make sure you don't get the one in the tail too hot or you will melt the switch.

Step 5: Try It Out

Though this build is simple it's insanely powerful, and is sure to wow
you and your friends. If you build one of your own please let us know how it turned out.
