The SturdiSignal™ Series is a fully certified range of LED navigation lights meeting UL1104 and ABS standards, specifically engineered for vessels over 20 meters in length. Designed for both commercial and military applications, these lights are suitable for retrofits and new construction, with mounting options compatible with popular brands such as Perko, McDermott, and Aqua Signal. They are available in multiple colors—white, red, green, and yellow—and in a variety of visibility ranges from 2 to 6 nautical miles, ensuring safe and reliable navigation in compliance with COLREG requirements. Location-specific configurations include port, starboard, masthead, tow, maneuvering, and all-around lights. Built in the USA, the SturdiSignal Series combines robust engineering with versatile installation options, making it a trusted choice for harsh marine environments.
One of the key advantages of the SturdiSignal is its modular, repairable design that reduces operational costs and simplifies maintenance at sea. Both the LED light source and the driver are housed in a single replaceable module, which can be swapped without tools or the need for an electrician. Spare modules are readily available, allowing vessels to maintain compliance with minimal downtime. Construction features include a marine-grade, machined aluminum housing with MIL-A-8625 Type 2 or Type 3 clear anodizing for corrosion resistance, as well as a UV-stabilized, weatherproof polycarbonate lens. The housing is seawater-resistant and IP66/IP68 rated for maximum durability. Mounting options include a 4-hole ½-inch King Starboard polymer plate in three available sizes (5.50 × 5.50 inches, 6.00 × 6.00 inches, or 7.00 × 7.00 inches), along with multiple plate configurations designed to match existing fixtures.
The SturdiSignal Series offers two head configurations: single head models and double head autonomous models. The double head version incorporates a patented automatic switchover function that activates when one head fails or drops below brightness requirements, doubling operational life and preserving vessel compliance. This model alternates heads at startup to extend LED lifespan and features a built-in LED intensity monitoring system compliant with IMO Resolution MSC 253 (83) 4.3. This system continuously verifies that light output remains COLREG-compliant and sends alerts to an alarm panel if brightness levels fall below standards or approach the 50,000-hour end-of-life threshold. Available power configurations include 120–240V AC and 12–32V DC inputs, with wiring options for single or double cable entry via a ½-inch NPT cable gland.
Performance-wise, the SturdiSignal Series uses high-powered LEDs rated up to 8W, arranged as 1–3 LEDs for single head units or 2–6 LEDs for double head systems. Visibility ranges vary by vessel size and application: 2 NM or 5 NM for port, starboard, stern, towing, and all-around lights; 3 NM or 6 NM for masthead lights; and 5 NM all-around white for maneuvering. The lights are capable of operating in extreme temperatures from -40°C to +50°C, making them reliable in both arctic and tropical marine environments. Their rugged build, autonomous operation capabilities, advanced monitoring features, and straightforward maintenance design make the SturdiSignal™ Series a premium navigation lighting solution for demanding maritime operations.
