Alarm Clock

Wake up light alarm clock 
How does the Wake-up alarm clock work? 
Select the time you want to wake up, and let a gentle sunrise ease you into your day. 30 minutes before your chosen wake-up time, the light will come on, very gently at first, and getting gradually brighter and brighter. By the time the 30 minutes is up, you should be fully awake, gently and naturally. You can adjust the brightness to a level that suits you. At the set wake up time, for extra reassurance, your chosen bird song or radio station can activate, to make sure you are awake.
