Dunn-Rite BUOY 4 Solar Powered Self-Illuminating LED Marker Buoy 20" Green

The Dunn-Rite BUOY 4 is a full-size, 20-inch solar-powered marker buoy designed to protect docks, floating swim platforms, floating trampolines, piers, PWCs, and swim areas. By day it serves as a highly visible standard marker buoy; after dark, its integrated solar light engine automatically activates to produce a brilliant, glowing beacon visible from up to ½ nautical mile away.

Key Features:

• Large 20" profile: Measures 20 inches high and 20 inches in diameter for maximum on-water visibility
• Solar-powered light engine: Watertight engine houses 5 super-bright LEDs powered by four 1.2V rechargeable batteries charged by onboard solar panels
• Long illumination runtime: Just 4 hours of direct sunlight provides up to 20 hours of continuous nighttime illumination
• Built-in photocell: Automatically turns LEDs on at dusk and off at dawn — no manual switching required
• Exceptional LED longevity: LEDs rated for up to 100,000 hours (approximately 20 years) of service life
• Long battery life: Rechargeable batteries last up to 2 years before needing replacement
• "Bell Shape" stability design: Keeps the buoy upright and vertical even in choppy, wavy water conditions
• Marine-grade stainless steel hardware: All rings and hardware resist rust and corrosion for lasting saltwater and freshwater use
• Weatherproof and waterproof construction: Every component, including the solar top and engine, is built to withstand marine environments
• Made in the USA: Manufactured in Elwood, Indiana since 1983

The BUOY 4 is finished in green and is ideal for marking navigation hazards, swim zones, dock perimeters, and mooring areas. Its combination of solar charging, automatic dusk-to-dawn operation, and durable marine construction makes it a low-maintenance, high-visibility safety solution for lakes, rivers, and coastal waters.
