Digital Ally's DVF-500 is an audio/video system inside a tough, water-resistant, machined aluminum flashlight. It features one-button activation, a wide-angle lens for easy aiming, pre-event recording to capture even before you press record, vibration/impact-proof solid state memory, and more.

SureFire's single-output G2ZX, designed for tactical use, produces 200 lumens of brilliant white light from a high-performance LED. It uses a micro-textured polycarbonate reflector to create a smooth beam with optimal light distribution. The CombatGrip design-reduced-diameter mid-section and rubber grip ring-is perfect for flashlight/handgun techniques and provides a secure hold. It also features ergonomic tactical switching: press the tailcap switch for momentary-on, twist the tailcap for constant-on.

Bayco's NSR-9914 rechargeable Nightstick has a powerful tightly focused flashlight (almost 900 feet of usable light) as well as an integrated floodlight built into the side. Because the floodlight has no reflector, all of the light spreads out in a wide even pattern for soft, even lighting perfect for searching areas or reading documents. You can use both lights at the same time (Dual-Light Innovation) to light up both the area ahead and the ground at your feet. All lighting modes can be selected from either the body or tail switch that operate in tandem.

The Streamlight Super Tac X features Streamlight's C4 LED technology with a 50,000-hour lifetime, delivering up to 200 lumens and 40,000 candela. The light uses a deep-dish parabolic reflector to produce a long-range targeting beam with optimum peripheral illumination to aid in navigation. The new model includes high- and low-intensity modes plus a strobe light.

Brite-Strike's BDRC-HLS flashlight has all the features of the BD-HLS flashlight plus a rechargeable lithium-ion battery in a compact, ergonomic, rugged design. Front and rear crenellated strike crowns can be used to apply pressure point techniques. The Tactical Touch switch design allows the light to be activated and operated using only one finger on one hand. The BDRC-HLS is completely water and shockproof and is covered by a lifetime warranty.

5.11 Tactical's Light for Life PC 3.300 flashlight charges in 90 seconds thanks to state-of-the-art patented technology. This lightweight, water-resistant, mid-size duty/utility flashlight produces 200 lumens and features a crack- and bend-resistant polymer body.

This palm-sized, highly-focused handy flashlight from River Rock won't blind yourself or others with too much power. The Perfect Circle flashlight's precision formed lens projects a precise focused hard edge yet soft full moon-shaped light beam, making it ideal for close up inside and outside activities. At 20 feet it projected a 41-inch perfect circle of light. The Perfect Circle flashlight can also emit a constant hands-free flash (about 80 flashes per minute) for signaling.

Designed for law enforcement, First-Light USA's Tomahawk LE tactical light with belt TRS clip has an ultra-bright white light plus red and blue LEDs that can be used individually or together in a safety strobe mode-alternating white, red, and blue strobing.

The Energizer Bravo Hard Case Tactical light is a multi-functional, multi-positioning illumination tool providing options and flexibility. Its swivel head rotates 130 degrees and allows the light to be used in both hands-free and handheld modes, while the light's red, blue, green, and IR LEDs enhance visibility in a variety of applications.

The Pelican 7060 LED light, developed jointly with the LAPD, employs new dual switch technology that allows the light to be activated by either a body-mounted patrol switch or a tail-mounted tactical switch. The dual switches, which include a momentary mode, allow the user to grip the light in several positions and still control activation. The light incorporates rechargeable Lithium-Ion batteries for maximum brightness.

With impressive light output and runtime for its size, BlackHawk's Legacy L6-P utilizes the latest generation 3-watt CREE LED for equivalent light output of a 7 or 8 D-cell flashlight. This compact, high-intensity LED flashlight produces a smooth, intense, pre-focused beam and comes standard with glass lens.
