The Streamlight PT 1L Professional Tactical Flashlight is an ultra-compact, extremely portable light that still provides enough output for tactical use. Its C4 LED delivers a powerful 180 lumen beam on its high setting, and also features a power-saving low setting as well as a strobe mode for additional versatility. Ten-Tap programming allows you to choose between high only, high-low and high-strobe-low modes for convenience, and its push-button tail switch is easy to use. Solid state power regulation systems provide consistent light output, so it won't dim as your battery runs low. The PT 1L is made from rugged aluminum and tempered glass, making it highly resistant to impacts, and also boasts IPX7 waterproofing to one meter for 30 minutes. It comes with an unbreakable pocket clip for convenient carry, and its anti-roll head keeps it in place when set down for hands-free lighting.
