The Streamlight Strion DS Compact is a portable flashlight that features Dual Switch Technology, which includes independently-operated head and tail switches for greater convenience. It features three power settings plus a strobe mode for signalling or dazzling targets, and its TEN-TAP switch allows you to select between three programs: high/medium/low/strobe, high only, and high/medium/low without strobe. Its advanced C4 LED provides a bright beam of white light with high-quality even illumination, and the regulated electronics maintain consistent output throughout the life of the battery. The machined aircraft aluminum body is highly impact-resistant, and its anti-roll head keeps it in place when set down. It is tested against two meter impacts and comes with an IPX4 water resistance rating. Its clamp charger is designed to prevent over-charging, and its Piggyback feature lets you charge a spare battery simultaneously.
