The Philips Wake-up Light Alarm Clock features a nature-sounds alarm and a colored sunrise simulation. This light-therapy device emits morning light that changes from soft red to warm orange to bright yellow, gently and gradually waking users with natural light. The alarm comes with a choice of five different natural and calming wake-up sounds. It also has an FM radio and a tap-to-snooze feature. At night, the bedside light dims gradually to promote natural, restful sleep.
