This 20W solar LED light offers easy-to-install off-the-grid lighting perfect for billboards advertisements and signs. It combines a solar panel and a Li-Ion battery in one fixture. At dusk the battery supplies power to the light source which provides 2000 lumens of neutral (4000k) white light. This output is comparable to a 150W HID light without the wasteful energy draw.
Our energy efficient light can last throughout the night with a single charge; the light will provide 100% brightness for 4 hours then it will switch to 25% brightness for the remainder of the low-light conditions. Along the side of the fixture is a battery percentage display so you can check the charge status at any time. The battery will last an average of 1500 charge cycles and you can replace the battery without replacing the whole fixture.
Since this is a solar light it does not connect to any power feeds. You can easily install this fixture using the included bracket mount without the need for or trenching or wiring. Enjoy the freedom of off-grid power with ultra-efficient solar lighting.
Note: Lighting duration is approximately 36 – 48 hours. The solar light can work continuously for 3 to 5 rainy days without charging the battery. The length of time the solar panel holds its charge depends on amount of sun exposure weather conditions and different working modes.
