Solar-powered spotlights are easy-to-install, low maintenance, no wiring, environmentally friendly lighting solution for your backyard, patio, garden, deck, porch or pathways. The advancements in the solar technologies and LED lighting have put them on the same line with the AC powered counterparts with the added benefit that they have no running costs because, well, they are solar! They include a light sensor which makes them turn on automatically when it's dark outside and off at dawn. The main components of a solar-powered spotlight are a solar panel, battery and LED lights. You'd probably not expect it but solar spotlights can get really bright. A button on its back will iterate through several light intensity positions from high to low brightness. You can either stick them into the ground using the spikes that are included in the package or screw them onto the outside walls with the included bolts. The solar panel can be tilted to adjust to the optimal sunlight direction. The spotlight itself has a swivel for directing the light on the object you need illuminated. You can point it to a tree to light it from bottom up or direct the light towards a sign in your yard to make it visible at night.
