The Solar Buoy acts as a standard marker buoy during the day but will illuminate at night via rechargeable solar light nestled at the buoy’s top. The watertight solar light engine’s generator will recharge in just four hours of direct sun, providing power to 5 super bright LEDs at night. The result is a beautiful glowing buoy visible from up to ½ nautical mile at night and can stay illuminated for up to 20 hours. The light engine’s LEDs will last for 100,000 hours or 20 years, and rechargeable batteries will last for up to 2 years before needing to be replaced.
