The Nightstick TCM-550XL Compact Tactical Weaponlight is an ideal illumination solution for compact pistols featuring a combination of a powerful 550-lumen output and a factory-focused Total Internal Reflection (TIR) lens. This gives you a bright and smooth beam free of holes or hot-spots with a tight center cone of light and a generous spill. An ambidextrous momentary or constant-on activation switch makes its use intuitive and easy, and a separate lock-out function on the bezel disables the light completely to prevent accidental activation during transport and storage.

Designed to fit compact pistols with integrated rails, the light comes with an adjustable rail mount and four sets of inserts to fit popular models from a variety of manufacturers. Its lightweight 6061-T6 aluminum housing is Type III hard anodized with a matte black to make it abrasion resistant, and it is gasket sealed to a waterproof IPX7 rating. Nightstick engineered the light to be compact and lightweight, so it is compatible with most weaponlight holsters available from major manufacturers. Powered by a single included CR123 battery, the TCM-550XL offers more than 2 hours of constant runtime.
