The Lumie Bodyclock Glow 150 is an alarm clock that mimics the light and color of a real sunrise, so when you open your eyes, you'll feel good awake and refreshed. Waking up this way helps to regulate your sleep-wake cycle and has even been shown to increase mood, energy and productivity for the rest of the day.   Bodyclock Glow 150 uses enhanced LED technology to produce smooth changes of light and color for a beautiful, realistic sunrise and sunset. Additional customization options allow you to choose the duration of the sunset and sunrise, add the light intensity of the sunrise alarm, and additional sleep/wake sounds. You can fall asleep to the gentle rhythm of rolling thunder ... and then wake up to a clear sunrise full of tropical birds or bleating goats. A truly natural start to the day Bodyclock Glow 150 offers fully adjustable bedroom lighting, bright for reading or a relaxing soft glow. If your room gets dark, the light-sensitive screen will turn off to help you turn off. Touch control snooze is another nice touch.   A sleep/wake light like Bodyclock Glow 150 isn't just a more fun way to start the day. It can help beat the winter blues and is a useful addition to a daylight lamp in the treatment of SAD (Seasonal Affective Disorder).   Features of the Lumie Bodyclock Glow 150 -Gradual sunrise of 20, 30 or 45 minutes to wake you up naturally -A fading sunset of 20, 30 or 45 minutes helps you fall asleep - Adjustable sunrise light intensity for a soft or clear sunrise - Mimics the colors of a real sunrise and sunset - 10 sleep / wake up sounds: beep, tropical birds, blackbird, café, goats, steam train, thunderstorm, waves, crickets, white noise - Night light option for low beam that stays on at low level - Light-sensitive auto-dimming screen - Touch-control snooze - Optional alarm signal - Back-up power failure - Mixed LEDs: warm white, orange, red - Product dimensions HWD cm: 16 x 19 x 12 - Weight 565 g.
