The Olight TACTICAL T25-T is one of the brightest AA powered flashlight made. For added convenience it features three levels of output, high brightness strobe and a low brightness SOS mode, making 5 total output possibilities.
Easily operated, the various levels/modes are adjusted by twisting the head slightly. The Olight illumination level/mode memory saves the last level or mode used before the light was turned off, returning to that level/mode when the light is turned back on.
The TACTICAL version also features a redesigned switch with a momentary feature at half-press and a redesigned body optimized for the cigar / syringe / Rogers hold alongside a handgun. The TACTICAL also offers a lockout feature to prevent accidental activation.
Easily operated, the various modes are accessed by pressing the tail cap switch. Illumination level is adjusted by twisting the head.
Digital regulation using the constant current technique
means that output at every brightness level will be constant not fluctuating with battery life. Additionally the constant current technique means greater efficiency for longer runtimes and the most effiencient usage of the battery.
The T25 TACTICAL will flash to warn you when battery power is low, giving you the opportunity to change batteries or adjust to a lower output level if you need more illumination time.
The Olight T25 TACTICAL utilizes a unique linear pattern for brightness adjustment; which is different from traditional PWM used by many competitors, to do away with the strobing effect some users can perceive.
