The 18350 Series Light is compatible with all Scout tailcaps including the Surefire UE and DS, and will also fit in any aftermarket Scout mount, as it retains the mounting holes and square lug interface on the underside of the light body.
Weight (with one 18350, no tailcap): 3.4oz
Length (without tailcap): 3.50"
Diameter: 1.23"
Power source: One 18350 rechargeable. This light will NOT run off a single CR123 cell. The Malkoff E2XTL and Modlite OKW DF and PLHv2 DF heads can run off two CR123 cells, but require switching to an 18650 length body.
The Arisaka light body, momentary tailcap, and head are CNC machined from 6061-T651 aluminum and MIL-A-8625 Type III hard coat anodized. High quality Buna-N O-rings and one rechargeable 18350 cell are included.
Made in the USA.
