The Gama Sonic Windsor Solar Light GS-99F is the perfect energy-saving and money-saving replacement for electric or gas-powered outdoor lighting. This outdoor solar powered post light is constructed with rust-resistant cast-aluminum in a powder-coated black finish and beveled glass panes and fits onto any existing 3-inch outside diameter lamp post (post not included). No electrical wiring required for installation, just place the solar post light in a spot with direct sunshine. At dusk, this solar powered post lights 12 bright-white LEDs will automatically turn on and illuminate 150 lumens for up to 10 hours on a full battery. Gama Sonic's patented cone reflector enhances the light output and glow. The monocrystalline silicon solar panel is protected by weather-resistant, cleanable tempered glass that helps ensure long-lasting reliability. A sunny day without overcast should be sufficient 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 panel.
