1、Material: The signal light features a rugged marine grade, high impact shell as well as a coated aluminum alloy anode shaft and stainless steel base to ensure that the stern light can withstand prolonged offshore work. 2、LED Light Source: The navigational light uses advanced COB LED bulb technology to provide a powerful and bright warning signal to prevent marine accidents at sunset, sunrise, or any time of day when visibility is poor. 3、Pole: With 360 degree light angle, the light signal 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. 4、Low Energy Consumption: The LED light consumes only 3W of power to emit bright and lasting light, which reduces unnecessary power consumption. Meanwhile, the 4000‑4500K white color temperature makes the light softer, and visibility farther. 5、Water Resistant: The light is marine grade IP66 water proof, the built in high performance sealing and water proof collar and aluminum alloy tube can effectively prevent water from intruding into the interior of the light, which greatly extends the service life of the pole light and is suitable for pontoons and fishing boats.
