Ex-Tesla and NASA Engineers Make a Light Bulb That’s Smarter Than You

25.09.2014 | |

Sometime in early 2013, one of the delivery operations engineers at Tesla leaned back in his chair and took a look around the Silicon Valley office. “It was a sunny day, and I looked up and I thought, ‘Why are these lights on with full power, when full sunlight is coming through the window?’” says Neil Joseph. An online search for a better, responsive bulb only yielded a few expensive commercial products. That October, Joseph (who says even as a kid, his two fascinations were lights and cars) left Tesla to start his own lighting company.
