The Viridian® Tactical Light is small and tucks neatly between the trigger guard and muzzle with no overhang. It will work with virtually any railed gun. This CTL features multiple modes of operation and provides 100 lumens constant use (140 lumens strobe). Battery life is 60 minutes constant and 80 minutes strobe. The CTL comes standard with RADIANCE® taclight technology, which expands light into a wider beam, revealing over twice the horizontal area of conventional tactical lights. With no wasted light above or below your target area, you get a better picture, faster discovery, smoother tracking and more positive targeting than other firearm-mounted lights. This light fits Security-Series pistols, the Ruger American® Pistol and other firearms equipped with a rail and is backed by a 7-year manufacturer’s warranty. Made in the USA by Viridian Weapon Technologies.
