Practical Lucas Solar starter set - the 10-bulb LED solar string lights for outdoors This battery-powered Lucas solar string lights serve as a starter set and are equipped with a solar module that can be flexibly positioned outdoors thanks to the ground spike. The fairy lights are fitted with 10 plastic LED bulbs that emit a warm white light and add a decorative highlight to your outdoor area. Whether on a patio, shrubs or even on the branches of a tree - the solar fairy lights are easy to position and light up at night after being charged by the sun. The solar fairy lights can be extended to up to 100 LED bulbs and then cover a total of 30 metres.
