With the Philips Wake-Up Light HF3506/20, you start your day easier, fresher, and with more energy. Light and sound are combined so that you wake up in a natural way. The lamp emits a bright yellow light and can be adjusted according to your own wishes via 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, choose from 2 different alarm sounds. Over one and a half minutes, you'll hear this sound slowly rising to the selected level. Use the snooze button when you can't get out of bed immediately. Can't get straight out of bed after the alarm went off? Use the snooze button to repeat the sound every 9 minutes.
