What it is: A solar-powered LED fairy string light for outdoor use. Each set carries 100 LEDs in a warm white tone on a 12 m string and is waterproof, so it suits gardens, patios, fences, trees, and party or holiday displays. Sizing and layout: One set covers about 12 m of run. Space the lamps evenly along the surface you are lighting. For a longer run, add a second set rather than stretching one string thin. Setup: Position the solar panel where it receives direct daylight, so the set charges through the day. Care: Wipe the panel with a soft dry cloth, because dust on the surface reduces charging. Bring the set indoors during storms or prolonged freezing weather.
