White laser light found to be just as easy on the eyes as LEDs

With incandescent light bulbs in the process of being phased out around the world, LEDs are one of the most promising technologies for taking over our day-to-day lighting needs – they use less energy, provide more light, contain less toxic substances, and are tougher than incandescents. That said, they may not be the one and only best choice. Lasers are even more efficient than LEDs at high amperages, although scientists have long believed that the quality of white light produced by diode lasers would be unpleasing to the human eye. According to a study recently carried out by Sandia National Laboratories, however, the human eye appears to like their light just fine.
