For off-grid families living at the base of the pyramid, the benefits of solar-powered light are clear. But for a huge portion of the market, even the cheapest lanterns are simply out of reach. Priced at around half the cost of existing solutions, A1 breaks this affordability barrier. Most users recover the $5 cost within 3 weeks of fuel savings, and thereafter enjoy a 10% increase in disposable income that can be invested in education, health, and the future. A1’s versatile design is ultra-portable but can still spread light to every corner of a room. Built with the durability d.light is loved for, it survives 3-5 years of daily use, even when dropped or left out in the rain. It is built of the highest-quality components available: the battery can last 3x the lifetime of iPhone batteries, even in extreme heat, and the solar panel and LED are among the most efficient in the world. A1 will transform life for millions of families who never imagined they could afford solar, giving them more hours to work and study at night without the fear of fire or stress of recurring costs, and will help d.light brighten 100 million lives by 2017.
