Hello everyone, I'd like to share my latest project, the Sigma Customs Hyperion. This is a custom, manually machined light that can host AA, or 14500 powered light engines in 6Al-4V titanium. It uses the excellent McR-16/S reflectors paired with a 15mm driver, calipsoii's excellent fully programmable AA driver (15VP), or a MTN-15DDm FET driver for 14500 engines with either guppy3drv or Crescendo firmwares. Switching is handled with an Omten 1288 reverse clicky switch, actuated by a metal piston that is sealed with a quad-ring seal and spring powered for a responsive action with no slop. The tailcap is tapped for 4-40x3/16" screws to hold an Oveready titanium clip.
Currently there are two head styles available, a finned version and a smooth version.
Nominal dimensions are 105mm long, 21mm OD head, 18mm OD body
Reservations have been closed.
