This contemporary designed solar LED house sign is produced from 3mm brushed aluminium & has hidden standoff fixings on the rear which allow the design to appear to float off the wall. The text is printed using specialist UV inks, which bond to the acrylic giving it a vibrant and tough finish. The brushed aluminium solar lights work by using a solar panel to generate energy from sunlight, converting it into an electrical current which charges the internal, rechargeable batteries. These batteries then power the lights. The in-built light sensor controls the lights, automatically activating them once the sensor detects dusk has fallen. Position the solar LED house sign at least 2 meters from other light sources. The closer the light is, the less effectively it will work. Please ensure the face of the solar panel is not shaded. Choose a place where it gets as much direct sunlight as possible. 100% weatherproof comes in light grey colour sized 25cm x 14cm.
