The Philips Wake-Up Light HF3471 uses a combination of safe, UV-free light and sounds to wake you up in a gentle and natural way so you're ready for the day ahead. Less jarring than conventional alarm clocks that rely on loud beeps or other noises, it's clinically proven to make waking up more pleasant. The Wake-Up Light also features a dusk simulation feature to help you fall asleep.
Simulates Dawn to Wake You Gradually
The official light therapy product of the National Sleep Foundation, the Wake-Up Light wakes you up by simulating sunrise. Light gradually increases for 30 minutes before your alarm time to gently prepare your body to wake up and feel more energetic at the start of your day.
When you turn off the alarm using the lever, the lamp stays on to give you the opportunity to get out of bed without switching on another lamp.
Choice of Three Natural Sounds or Radio
At your set wake-up time, you'll start to hear a natural sound or your selected FM radio station. These sounds start out quietly and take 90 seconds to reach your selected full volume level. There are three sounds you can choose from: morning birds, a beep sound, and wind chimes. A snooze button feature lets you enjoy nine more minutes of sleep before the sounds start again.
Choose Your Light Level for Natural Awakening
Because different people have different light sensitivities, the Wake-Up Light lets you select the light intensity that best suits your personal preferences. The intensity level can be set up to 250 lux. Higher settings typically correspond with shorter wake-up times, while lower settings may result in a more gradual wake-up process.
Fall Asleep with Diminishing Light and Sound
The Wake-Up Light can also help you wind down and drift off to sleep at bedtime. The dusk simulation feature works by gradually dimming the light and lowering the sound to help you drift to sleep.
Bedside Lamp with 20 Light Settings
The Wake-Up Light can be used as a bedside lamp for reading. The 20 different brightness settings allow you to choose a light intensity that's best for you. It has an easy-to-read digital display. Menu, select, and volume buttons are conveniently located underneath the time display.
Backed by Clinical Research
Independent research shows that 8 out of 10 Wake-Up Light users reported that the device made it easier to get out of bed. Additionally, 88 percent of users say the Wake-Up Light is better than their previous way of waking up. It has also been clinically proven that light wakes you up more pleasantly and improves the quality of waking up.
