Marine location marking systems
LED Marine Marker 25/58
40-minute target endurance.
Mk 25-class package.
A high-intensity 360° electronic marine location marker designed for extended-duration visual signalling without pyrotechnic composition.

*Performance claims are subject to confirmation against the exact 360° product configuration, supporting test conditions and final qualification. Visual range depends on the test method and atmospheric conditions. Peak intensity is not effective flashing intensity.
One platform. Two mission durations.
Mk 25-class package dimensions with the capability to support short- and extended-duration visual marking operations.
12.5 minutes
Standard-duration configuration designed for Mk 25-class missions.
40 minutes
Extended-duration configuration targeting Mk 58-class signalling duration in the same platform.
A common platform offers an opportunity to simplify procurement, inventory and logistical support.
The advantages of non-pyrotechnic marking
No pyrotechnic composition
Removes hazards associated with pyrotechnic combustion.
Simpler logistics
Potentially reduces transport, storage and handling constraints, subject to battery classification.
Lower lifecycle cost
Potential savings in manufacture, logistics and end-of-life disposal.
High-intensity LED signal
Distinctive 360° triple-flash signalling for day and night operations.
Designed for maritime & aviation operations
Maritime patrol
Air-deployed surface reference marking.
Search & rescue
Visual identification of search areas and locations.
Man overboard
Extended-duration surface location marking.
Naval operations
Training and surface marking missions.
These are intended applications, not claims of completed qualification. Smoke, flame, wind-indication and infrared functions are not automatically replicated by visible LEDs.
Engineering and independent testing
Request the independent photometric testing and photobiological safety evidence applicable to your supplied configuration.
Peak luminous intensity: contact Denis Ferranti for measurements supporting the 40,000+ candela figure and confirmation of applicability to the final 360° configuration.
Photobiological safety: request IEC 62471 evaluation details, including the measured classification and viewing conditions.
