OK, I have the switch out of my Mag 3D, and I have wire, hotlips heatsink, and Luxeon 3watt emitter ready to install for direct drive. I have a piece of mica insulation to prevent electrical conductance between the emitter and the heatsink. But, does anyone know if the emitter base is negative or positive? Lumileds pdf simply says insulation is required because the base is not isolated.
I'll be checking this out, but if the base is negative, is there any reason that I cant't use it for the negative terminal? The body of the maglite is connected to the battery negative normally. I suppose I will need electrically conductive as well as thermally conductive heatsink paste.....Are there any other recommendations? -RussH
