2D Cut down Maglite It has an XM-L T6 emitter and holds 3AA NiMH in a holder. You could use a 26650 or 32650 Li-ion. I imagine someone could even put an 18650 in it with some type of spacer around the battery. I made the 3AA holder about the right length for 65mm length. Spring might need to be cut and if using a flat top, a magnet will be needed to have contact with the pos terminal, for the switch.
Please see the build log for all the info on this light. It's new, just bought it to do the mod.
