Philips kicked off the smart bulb market nearly three years ago with its pricey Huebulb, but at this year's CES a horde of new entrants emerged.  The transition from incandescent to more energy efficient bulbs is an opening through which smart bulbs – LED bulbs with wireless radios built in, which can be controlled remotely – are gaining a foothold according to Strategy Analytics' Smart Home Strategies latest report. Belkin, GE and Philips are joined by Awox, Cree, LIFX, Sengled and a host of others are profiled in "Smart Light Bulbs: The Competitive Landscape".
