The "Hue White Ambiance" bulbs (800 lumens, $30 retail), which have controllable color temperature and dimming, can go from 2200K to 6500K.
The "Hue White" bulbs (800 lumens, $15 retail), which have only dimming, are fixed at 2700K.
Given that the new bulb is 470 lumens for $40 retail, one would hope it'll have controllable color temperature.
Oh, the press release says:
"The Philips Hue candle light bulb is a 40W equivalent E14 – 470 lumen at 4000 kelvin – and is available in white ambiance, providing a broad spectrum of white light; or white and color ambiance, with a range of more than 16 million colors. Both bulbs feature deep dimming from warm white to cool daylight with a 2200k – 6500k color temperature range."
Nice, thanks.
