Princeton Tec Impulse - Black

The Princeton Tec Impulse in Black is the versatile personal light every angler, boater, and water enthusiast should keep within arm's reach. Built for hands-free operation and rapid deployment, this compact flashlight serves double duty on the water—whether you're tying knots at dusk, navigating back to the dock in failing light, or signaling to nearby vessels. Its lightweight design and multiple carry options make it an essential addition to any tackle bag, life jacket, or boat locker without adding bulk or weight to your gear.

Powered by two lithium coin cells, the Impulse delivers remarkable runtime—up to 36 hours of continuous operation on a single battery charge. The Ultrabright LED produces a focused beam with three distinct modes: low for subtle illumination during night navigation, high for task-intensive work like lure inspection or equipment repair, and flash mode for emergency signaling. The quick-release clip and hat clip allow you to position the light exactly where you need it, freeing both hands for fishing, boat operation, or safety procedures while maintaining optimal visibility.

Boaters benefit most from owning multiple units—one clipped to your cap for hands-free night fishing, another secured to the boat's rail for courtesy lighting, and a spare in your emergency kit for backup. The rugged construction withstands the corrosive marine environment, salt spray, and the inevitable splash of bilge water or baitwell overflow. At just 0.2 pounds and measuring a compact 3 x 1 x 8 inches, the Impulse fits comfortably in shirt pockets, tackle boxes, or emergency survival kits, making it the practical choice for serious anglers who demand reliability when conditions deteriorate.
