The UB3T Invictus Variable-Output LED Flashlight from Surefire is an 1000-lumen maximum output LED light designed for tactical professionals. The CombatGrip configuration has a reduced mid-section diameter and a rubber grip ring that facilitates comfortable use with standard and the modified Rogers/SureFire flashlight/handgun technique. This innovative body shape is also useful for maintaining a secure grip in cold or wet conditions, even when wearing gloves. SureFire's TurboHead Total Internal Reflection (TIR) lens produces a large pre-focused beam that has a tight center cone of bright light, with a dimmer ring on the periphery to help maintain situational awareness.
The Invictus features the Max-Blast tactical tailcap switch and an output selector-ring forward of the handle. Rotate the selector ring to choose off, strobe, SOS or one of eight beam intensity levels from 2 to 1000 lumens. The Max-Blast switch works similar to most two-stage tactical tailcap switches by offering momentary activation by pressing the pushbutton or constant-on with a twist of the tailcap. What sets the Max-Blast apart is that no matter what output the flashlight is set to, fully pressing or twisting instantly activates the 1000-lumen output. In tactical situations, the benefit of this is obvious.
For emergency signaling, the SOS mode will constantly cycle through the Morse code sequence. Its strobe mode is designed as a less-than-lethal option to disorientate and temporarily blind. The light also has two lock-out features, on the tailcap and selector-ring, to prevent accidental activation during transport or when strict light discipline must be maintained.
Designed for durability, the light features a weatherproof O-ring and gasket sealed Mil-Spec anodized aluminum body with a tempered and anti-reflection coated lens window. A battery-level indicator on the selector ring enables confident power management.
