Material: The light features a rugged marinegrade shell, a coated aluminum alloy anode shaft, and a stainless steel base to ensure the stern light can withstand prolonged offshore work. LED light source: The navigational light uses advanced COB LED bulb technology to provide a powerful and bright warning to prevent marine accidents at sunset, sunrise, or any time of day when visibility is poor. Pole: With a 360 degree light angle, the light can be clearly seen no matter which direction the vessel is coming from. Screw mounting prevents the light from shaking or falling off during navigation. Low energy consumption: The LED light consumes only 3W of power to emit bright and lasting light, which reduces unnecessary power consumption. Meanwhile, the 40004500K white color temperature makes the light softer, and visibility farther. Use scenarios: Offshore work or transit at sea where durable construction and reliable visibility are essential for safety. Nighttime docking, channel navigation, or closequarters maneuvers where 360degree visibility and secure mounting reduce risk. Conditions with reduced visibility such as dawn, dusk, or fog, to ensure the vessel remains clearly seen by others.
