The Hue White and Color Ambiance A19 Starter Kit contains the Hue Bridge and four White and Color Ambiance Hue bulbs. Now with richer colors, this kit forms the basis of your Hue Personal Lighting System. With all shades of white light and all colors to choose from, there are limitless possibilities to turn your everyday lighting into an extraordinary experience. With Hue, you can paint with light and change the mood of your home to match any moment with just the press of a button. You can customize your daily routines, using preset shades of white light to help you energize, concentrate and relax throughout the day. Let Hue wake you up gradually for a fresh and gentle start to each day instead of an abrupt alarm and relax with a cozy, warm, light gradually turning off as you fall asleep. If you are working late or away on vacation, you can make it seem like you're home when you are not with Hue's away-from-home control, allowing you to change your lights from anywhere. And when you do return home, Hue can welcome you with a lit house as your approach. You can even set the lights to come on at a pre-set time and turn off gradually. Hue can sync to your music and movies by lighting up to the beat of your favorite song and transforming any room into a dance floor or expanding your TV experience to the whole room by syncing your lights to match your favorite team's colors when they score.
