Wake up in a pleasant way with the Philips HF3531 wake-up light. Stylish design, neat and compact.

Wake-up functions
In the morning, the light increases gradually 30 mins before the programmed alarm time, just like a real sunrise. You will feel more refreshed and it will be easier to get out of bed. The wake-up light has 7 alarm types, birdsong, zen melody, calming piano music, yoga music, etc. that gently gets louder until it reaches the selected volume. You can also programme your wake-up light so that you wake up to your favourite FM radio channel. Snooze function (9 min).

Sunset simulation
When going to bed you can switch the light to sunset simulation mode, that gradually reduces the light and sound so that you can relax and go to sleep easily.

Auto dimmer
The screen will dim automatically in conjunction with the light in the room. A bright room will increase the light on the screen and when the room gets dark the light diminishes so as not to disturb your sleep.

Midnight light function
Just enough light to find your way in the dark. The midnight light setting shines with a dim, soft-tone orange light that is designed to minimise disturbance to your sleep. The midnight light function is simply activated and deactivated by tapping the top of the light.

USB port
The light also has a USB port for charging your mobile phone.
