Daniamant W4 Lifejacket Light — Reliable Illumination for Maritime Safety
The Daniamant W4 Lifejacket Light is a water-activated, high-performance survivor location light designed to enhance visibility and safety in marine emergencies. Built to meet SOLAS, MED, and USCG standards, the W4 offers proven reliability under the toughest maritime conditions.
Key Features
Automatic Activation: The W4-A version activates automatically upon immersion in water, ensuring immediate illumination even if the wearer is unconscious. It can also be turned on or off manually via a front-mounted switch.
Powerful Output: A bright white flashing LED delivers a minimum light intensity of 0.75 candela for over 35 hours—exceeding international safety requirements of 8 hours.
Durable Construction: Made from robust ABS and polycarbonate materials, the W4 is fully sealed, dust-tight (IP6X) and waterproof to IPX7 and IPX8 standards, verified through independent TÜV SÜD and Particle Technology testing.
Compact and Lightweight: At just 42 grams, its low-profile design minimizes snagging hazards while maintaining high visibility on all types of lifejackets.
Versatile Mounting Options: One light fits all—use the supplied belt clip, tube clip, or recessed housing to suit foam or inflatable lifejackets.
Maintenance-Free Operation: Designed for a five-year storage life with minimal upkeep; a test probe is supplied for easy functionality checks.
Certifications and Approvals
The W4 Lifejacket Light holds approvals from major authorities, including:
DNV MED-B and UK MER-B Type Examination Certificates for compliance with SOLAS and IMO LSA Code
Transport Canada recognition under DNV Type Approval Certificate TAE000051V, confirming suitability for use on all DNV-classed vessels
Why It Stands Out
The W4 embodies Daniamant’s commitment to safety innovation—offering an environmentally friendly alkaline battery alternative to lithium models without compromising performance. Its simple operation, robust design, and universal compatibility make it a trusted choice for commercial and recreational marine operators alike.
