SureFire KM1‑E

SureFire KM1‑E “Vampire” head, a dual‑spectrum (white + IR) LED bezel for 1‑cell Scout‑pattern lights like the M300 series.

What it is

• Conversion head that gives older M300A/B/C Mini Scout lights both white and IR output from a single CR123.

• Used widely on rifles and helmet mounts where you want a compact multipurpose white/IR light instead of a dedicated IR illuminator.

Key specs

• White output: 250 lumens, about 9,300 candela, rated distance around 190 m.

• IR output: 100 mW, ~6 hours runtime in IR mode on one CR123A.

• White runtime: ~1.5–2.5 hours depending on spec sheet/revision.

• Weight/size: ~1.28 oz with battery, 1.78 in length, 1.06 in bezel diameter
