James Vincent, writing for The Verge on Philips' new set of Hue bulbs:
Are you a light connoisseur? Can you tell the difference between "cool daylight" and "warm white"? If so, Philips has just announced what could be your next favorite lightbulb: the Philips Hue white ambiance. The company promises that the white ambiance delivers "every shade of white light" from color temperatures of 6,500 k to 2,200k. And by hooking up the bulbs to the new Philips' Hue app, you can use the "Routines" feature, which shifts the color temperature of the bulb as the day progresses, supposedly leading to better sleep.
Sounds like a good companion for the upcoming Night Shift in iOS 9.3. I've already been dimming my Hue lights manually after Night Shift turns on, so I should probably upgrade to these bulbs in my living room. They'll be available in the US this Spring.
