The LNK-LB-01B Lifebuoy Light is a lithium battery-powered emergency light designed for man overboard situations, meant to be installed with lifebuoys. Equipped with both gravity and water sensors, this lifebuoy light activates through a dual system. Upon immersion in water, the LED lamp automatically orients upwards due to its gravity design, activating and emitting a flashing white light with an intensity exceeding 2.0cd for at least 24 hours (14 hours at -1℃). This continuous illumination significantly enhances the visibility of the lifebuoy, increasing the likelihood of a successful rescue. Additionally, the light is designed to float on the water and features an automatic turn-off mechanism when not in water or when the LED lamp is oriented downwards. The LNK-LB-01B embodies an advanced solution for maritime safety and emergency response.
