What do you use when you need a bright light to illuminate the night...? I own two of these...one for my nightstand, and one for my Jeep. ========================= =============================== SPECIFICATIONS Max Output: 65/120 lumens With optional ultra-high output lamp Runtime: 60/20 minutes With optional ultra-high output lamp Length: 5.10 Inches Weight: 5.30 Ounces Battery: Two 123A Lithium FEATURES Rugged aerospace-grade aluminum body, available with Type II anodizing in glossy black or Mil-Spec Type III hard anodizing in olive drab O-ring sealed, weatherproof Tempered Pyrex® window Pocket clip Tailcap switch: press for momentary-on, twist for constant-on Switch lockout prevents accidental activation during transport or storage The C2 Centurion is a compact (palm size) high-intensity incandescent flashlight for duty and tactical use or conditions requiring enhanced grip, similar to their Z2 but with pocket clip and slightly heavier body. Patented rubber grip ring allows the light to be operated with a handgun using the Rogers/SureFire technique. Puts out a smooth, brilliant, pre-focused tactical-level beam with four times the light of a big two D-cell flashlight - bright enough to temporarily blind and disorient a person by impairing his night-adapted vision. Light output may be nearly doubled with optional P61 lamp.
