With the Philips Wake-Up Light HF3506/05, you'll start your day more easily, fresher, and with more energy. Light and sound combine to wake you in a natural way. The lamp emits a bright, yellow light and can be adjusted according to your wishes using 10 pre-programmed light settings. When your alarm clock goes off, it takes about 30 minutes for your bedroom to be lit completely to 200 lux. To wake up completely the way you want to, you can choose from 2 different alarm sounds. Over one and a half minutes, you'll hear this sound slowly increasing in loudness to the selected level. Still can't quite get out of bed after the alarm goes off? Use the snooze button to repeat the sound every 9 minutes.
