LIFX® is a wifi enabled, multi-color, energy efficient LED light bulb that you can control with your smartphone. LIFX is like going from black and white television to full-color HD. Imagine the ability to transform the ambience of your home or workplace using your smartphone. Wake up naturally each morning with automatically increasing light. Improve the quality of your sleep, drifting off with slowly dimming lights. (available soon via free app update) With LIFX there is no need for electricians or complicated control boxes. Just replace your existing bulbs with LIFX bulbs. The LEDs in LIFX bulbs are also rated to last up to 40,000 hours. That's 27 years at 4 hours use per day, so sit back and relax.
