Philips has spent years extolling LED lighting, which is long lasting and consumes far less energy than other lighting. But over the past year the company has been building solar-powered LED complexes throughout Africa—transforming 87 underused health clinics and giving kids the ability to read and play after dark. The initial outlay for the project is donated. But there’s an upside for Philips in the lighting project, which has given it a foothold in numerous new markets and boosted orders for its tablet-size ultrasound machine, Visiq—a lifesaving device for doctors in remote villages.
