The CTL Universal Sub-Compact Weaponlight fits on most handguns with a rail between the trigger guard and muzzle and shines 100 lumens of white light to give you the advantage in a tactical situation. The light is also equipped with a 140-lumen strobe. Adjustable for elevation and windage, it can be activated automatically if used with the optional Tacloc holster. Runtime is one hour for the light and 80 minutes for the strobe.
