This Philips Hue white ambiance starter kit contains 3 bulbs, a bridge and a switch. It can help you fall asleep or wake up gently. Set the right ambiance with a range of white light, from cool daylight to relaxing warm white light. With the Philips Hue iOS and Android apps, you can control your lights remotely wherever you are. Check if you have forgotten to switch your lights off before you left your home, and switch them on if you are working late.
