This flashlight was built for weapon mount, long range use. It features solid copper heat sink, Ebay seller DTR-LPF PT54 red led, Optolife 50mm Aspheric lens, Direct Drive 4/3AF (18650 size) NiMH batteries, 18GA Teflon wire and a MF $13 TR-1200 HOST W/Ebay extension. Wire tape switch (too much resistance) will have to be reworked probably MOSFET switched. Using standard switch or copper penny :) . Running 3 cells was able to pull 12A. A bit high but this a short run time light. All copper parts turned and host bored for press fit. Not finished but work in progress.
