Editor's Note: Streamlight has renamed this line as the X Series line, re-introducing it at the Police Security Expo trade show in June. View full details here .

Streamlight Inc. has introduced the Scorpion XL, the Nightfighter  XL, the TL-2 XL and the Super Tac XL, high-performance models of its Tactical Series personal lights. The company also increased the light output of existing versions of the same flashlights, including the Scorpion LED, the Nightfighter LED, the TL-2 LED and the SuperTac.

The new XL versions use the latest in C4 LED technology to deliver extreme brightness and illumination. Each of the new XL lights also features a strobing function, useful for signaling purposes in the field, or for disorienting potential suspects. 

"All of Streamlight's Tactical Series are designed to give users a clear advantage during confrontations or on patrol under low light conditions, and are among the most powerful, compact and lightweight lights available," according to Ray Sharrah, Streamlight's president and chief executive. "By introducing the new high-performance XL models, as well as improving the existing line with power LED technology, we are giving users a variety of options from which to choose, depending on the environment in which they are operating."

The new XL models each feature a C4 LED with a 50,000-hour life, and deliver up to 200 lumens measured system output and 40,000 candela, which is the brightest spot of a focused beam. In addition, the Super Tac XL also uses a deep-dish parabolic reflector to produce a long-range targeting beam with optimum peripheral illumination to aid in navigation.  The Nightfighter XL and Super Tac XL each feature high and low intensity modes, while the Scorpion XL and TL-2 XL also each feature a medium setting.

On the highest setting, the new XL models provide up to 2.5 hours of run time to 10% of the initial lumen output and up to 50 hours of run time on the lowest setting. Each uses two 3 Volt "CR123A" lithium batteries with a shelf life of ten years.

The upgraded versions of the existing LED tactical lights also each use a C4 enhanced LED  to deliver up to 160 lumens measured system output and 30,000 candela. The upgraded models provide up 3.5 hours of run time to 10% of the initial lumen output and also use two 3 Volt lithium batteries.

All eight of the new models are manufactured from 6000 series machined aircraft aluminum with an anodized finish and feature a push-button tail switch. The lights, which are all available in black, range in weight from 4.7 to 7.1 ounces and in length from 4.9 to 6.62 inches. Both the Super Tac and Super Tac XL also fit Streamlight 69100 rail mounts and operate with remote switches.

Each light is IPX4-rated and impact resistant to at least two meters. The lights range in price from $82 to $118.
