The Gama Sonic Imperial II Solar Light GS-97NF is a single solar lamp head for both residential and commercial properties that features a traditional design and fits onto any existing 3-inch outside diameter lamp post (pole not included). This outdoor solar powered post lamp is constructed of cast aluminum with a powder coated black finish and beveled glass panes. No electrical wiring is required for installation, making it the perfect solar LED light to install while offering an energy and money saving alternative to electric or gas-powered outdoor lighting. The replaceable Lithium-ion battery pack is good for about 1,000 charges (roughly 3 years) and charges when sunlight hits the solar powered post lights integrated solar panels. This solar outdoor post light will operate automatically from dusk-to-dawn and requires at least 4-6 hours of direct sunshine on the solar panel. On a full charge, the solar post light fixture will have a duration of up to 30 hours (on a low operation mode) and illuminates 300 lumens in a bright-white color temperature. The monocrystalline silicon solar panels are protected by weather-resistant, cleanable tempered glass that helps ensure long-lasting reliability. A sunny day without overcast should be enough to provide a full recharge. Recharging speed will vary based on weather conditions, but no charging will occur if direct sun does not shine on the solar panels. Do not locate the solar post light in a shaded area.
