This compact flashlight features either momentary or constant-on functionality and has a rotating bezel ring that allows the user to adjust the focus of the beam. The housing and tail-cap are made from aircraft-grade 6061-T6 aluminum and have a Type II hard anodized finish. Power comes from two AA batteries (included).
