Innovation That Matters

Instead of kerosene, a solar-powered light bulb

Property & Construction

Kerosene lamps are a fact of life in all too much of the developing world, despite their toxic and polluting nature. We’ve already seen a few different efforts to change this — both through microloans for green energy and through an energy-storing soccer ball — but recently we came across another: a solar-powered light bulb. Just launched this week by Denver- and Hong Kong-based Nokero (which stands for “no kerosene”), the Nokero N200 lasts six or more hours on one day’s charge and is affordable to the billions of people worldwide who live without reliable access to electricity. The N200 is a new, improved version of Nokero’s N100, which launched in June, and offers 60 percent greater brightness, the company says. Featuring one solar cell and four LEDs along with a brandable frosted globe, the bulb uses the solar energy it collects to power one AA-sized, 1.2 V, 1000mAh, replaceable and recyclable Ni-MH battery, which is used to provide light at night. The Nokero automatically turns off in bright light to save energy; it also features a multi-switch that can be set to high, low or off. Like the N100, the N200 is rainproof and durable so it can withstand outdoor use in tough conditions, ranging from -20⁰C to 55⁰C. With a pivot feature for maximal solar charging, the bulb can be hung or laid on its side. A video on YouTube demonstrates the bulb in use. Priced starting at USD 15 per bulb, the Nokero N200 is already being used in Pakistan and Kenya, and it will soon arrive in Iraq, where it will help people in the war-torn country avoid the high cost of running diesel generators for light at night. More than one million people die each year in fuel-based lighting fires, and an additional 1.6 million are estimated to die from indoor air pollution, says Nokero, which also offers a “buy one, give one” program with discounted prices.
