ACR C-Light™ H20

The ACR C-Light H2O is a water-activated personal distress light engineered for boaters and mariners who demand reliable signaling in emergency situations. This compact, rugged light combines intense LED technology with extended operating life, delivering the steady-on illumination required for search and rescue operations when every second counts. Weighing just 0.1 pounds, the C-Light H2O is tiny enough to fit in a pocket, lifejacket, or survival kit, yet durable enough to withstand the harsh marine environment.

The light's 20-lumen LED output provides visible signaling in darkness and low-visibility conditions typical of water-based emergencies. The device activates automatically upon contact with saltwater or freshwater—a critical feature when your hands are occupied or compromised. Manual activation is also available via an easy twist-on mechanism, giving you control when preflooding or testing is needed. Typical continuous operating life reaches 30 hours, meaning the light remains visible throughout extended search operations without battery replacement. The waterproof construction is mandatory for any device intended for marine use, eliminating corrosion concerns that plague conventional distress lights in salt-air and immersion environments.

This distress light is essential for offshore anglers, cruising sailors, commercial fishermen, and recreational boaters who operate beyond immediate help. Weekend fishermen on inland waters benefit equally—unpredictable weather and mechanical failure can force any vessel into emergency signaling mode. The C-Light H2O meets the practical requirements of U.S. Coast Guard safety recommendations for personal locator lights and represents a low-cost insurance policy against worst-case scenarios. At 4 × 1 × 9 inches, it stows anywhere without the bulk of traditional flare kits, and unlike pyrotechnic flares, it requires no expiration date management, certification renewal, or fumigation paperwork.

The marine distress light category demands reliability over style. The C-Light H2O from ACR Electronics—a company with decades of experience in marine safety equipment—prioritizes function and durability. Its simple activation method, proven LED technology, and waterproof design have made it a standard choice for lifejackets, safety kits, and emergency go-bags aboard commercial and recreational vessels. For boaters serious about preparedness, the ACR C-Light H2O is the practical, compact distress light that performs when it matters.
