The Solar Basics Solar Wall or Step Security Light with bright white temperature lights is the perfect security light for illuminating dark pathways, steps and decks. The solar powered wall light is constructed of resin with a black finish and polished pencil edge. At dusk, this light will automatically turn on and provide 700 lumens for up to 10 hours on a full battery. Installation is as simple as screwing the solar accent light into the wall. No electrical wiring is required, just place in a spot with direct sunshine. The outdoor solar lamp includes integrated 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 sufficient to provide a full recharge. Additionally, the replaceable lithium-ion battery pack is crafted to last for about 3 years, or roughly 1, 000 charges. Recharging speed will vary based on weather conditions, but no charging will occur if direct sun does not shine on the solar panel. Do not install or mount the solar light in the shade.
