older Surefire shock islated combined with E2E black HA body by E2C adapter.
P90 9V bulb driven by 2x R123 li-ion cells. One has to be protected for this to work safely. Yank both cells at the first sign of dimming to avoid killing your li-ion cells.
Results is 105 guilt-free lumens in a small package
