New Uses for Old Technology
The perfect light bulb arrives Back in September 2009, I got very excited about dimmable LED bulbs. They cost $40 apiece, they were only 7W — a 40W equivalent, in terms of brightness — and it wasn’t obvious how dimmable they were. But back then and for a long time afterwards it seemed as though Philips were the only real player in the dimmable-LED-bulbs game. But now Farhad Manjoo has found something even better, from a startup called Switch Lighting. Its brighter: Switch offers both 60W and 75W equivalents in the warm-white color of incandescents. And they’re only $20 apiece, compared to $45 for something similar from Philips.
