Green high-tech technology in a traditional mason jar. That's the SONNENGLAS®. The principle of this solar light is as simple and fun as it is ingenious: The SONNENGLAS® stores energy during the day and releases light at night. Producing light in this way is fun, sustainable and makes it easy to do your bit for the environment. And the SONNENGLAS® will light up the dark for years to come. The SONNENGLAS® contains four solar-powered LEDs, which are charged by solar cells in its lid. When placed in direct sunlight the batteries are charged and provide many hours of soft, yet bright lighting without glare. The SONNENGLAS® is ideal for garden lighting, decorating your table and other areas, barbecues, camping, alfresco dining and all other outdoor pursuits that would benefit from beautiful lighting to create a wonderful and relaxed atmosphere.
