im gonna do a 3d mag direct drive conversion, need help

Im a newbie, and i have decided that just like every other one of my flashlights, stock isn't good enough. Now im gonna do a direct drive luxeon star conversion in my "dim" 3d mag, but have one question: is there a way to do the conversion wile remaining a level of focusability? I dont want a flood, just a spot, and a medium spot to low flood? like on the stock mag when the black hole disappears on a wall 10 feet away, if u have one. Any input is greatly appreciated.

Thanks
