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.

Philips Wake-Up Light feature
Choice of Four 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 four 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. For further convenience, the Wake-up Light Plus features two alarms, ideal for weekday/weekend settings.

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.

USB Connection Allows you to Wake up to Your Favorite Tunes

The Wake-Up Light Plus has a USB connection for easy mp3 or smartphone hook-up. Let your favorite tunes help start your day on the right note.

Smart snooze - Tap Anywhere to Snooze

You can put the Wake-up Light into snooze mode by simply tapping anywhere on the product. After 9 minutes the sound will gently start playing again.

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.

There are a few more details I think that will help make the decision for/against this purchase if you are considering it:

When I was considering this and reading all the reviews, it sounded like the light alarm would not automatically turn off. I found that if I set it for a time (4 AM, so starts to ramp up at 3:30 AM) it will automatically turn the light off after 2 hours from ramp up (5:30 AM). I set my alarm to radio with sound off, so I'm not sure what happens with the sound portion if you let it run like that, so YMMV.

I had gotten the impression from another review that you had to toggle the alarm on/off every day to turn the alarm off/reset it for the following day. If you just use the off buttons on the side you don't have to do that. Since I purely use the light portion, that means just a tap on the lamp on/off button turns it off and it is still set for the next day. I would guess that if you have the sound on you would probably need to hit the sound on/off button to turn off that half of your alarm.

It isn't said anywhere that I read, but the sunset simulator portion of this isn't set to an alarm type function like the sunrise portion is. IMO this is annoying, since I planned on using it as an automatic function to make sure I went to bed at a more reasonable time. So keep in mind that if you are in it for that feature, you will have to set it every time you want to use the sunset simulation.

Those points aside, here is my main review:

I bought this since I've struggled with seasonal affective disorder. I use a regular light therapy lamp, but often find I forget to use it. This makes sure I do get my light in, regularly and early. I haven't had to struggle with the urge to sleep 24/7 at all since I started using this.

I have never slept well, and therefore have never waked up easily. Though this was an expensive item, I was willing to try it.
It does just as advertised: going from dark to your selected maximum light level over the course of 30 minutes, ending with the sound you select to serve as the auditory alarm, this device wakes you up slowly by taking advantage of your own body's natural response to increasing light. Do follow the suggestion to immediately note the light level when you first wake up, the first time you use it, and set that as your maximum light level, or you will be brought awake both too early and too quickly to receive the benefit of the slow awakening.

Pros: despite initially confusing directions, if you follow them step by step you can get the device set up in just a few minutes. An FM radio option is included for your wake up sound, as is a USB jack for using your own music. I haven't tried the dusk simulation that gradually lowers the lighting as you go to sleep. The switch for turning the alarm off is easy to find and manipulate, and a touch anywhere snooze function is nice, though the length of the snooze is not adjustable. The light is warm and the gradual increase leaves a very natural feeling of dawn taking place.

Cons: However, turning off the audible alarm does not turn off the light. Despite what the instructions imply, that light won't turn off automatically - you must turn it off, separately from the audible alarm. Also, don't mistake it for a usable clock. The time readout is barely an inch high, and no one with even a moderate nearsightedness could ever read it at night. This has left me with the odd arrangement of the wake-up light as the primary alarm on my night table, and a regular alarm as the needed clock.

Vine Customer Review of Free Product ( What's this? )
இ Fuzzy Wuzzy's Summary:
ѾѾѾ Somewhat recommended, with reservations and only lukewarm fuzzies.

This is a nice fancy alarm clock that wakes you up very gently to a variety of alarm sounds, using a combination of light and sound that slowly ramps up in intensity, instead of the conventional alarm clock approach that can rudely and abruptly wake you up with a loud sound or music. The "Plus" model offers the additional option to wake up to sounds/music from a USB flash drive plugged into it, an additional dusk simulator function that slowly dims the light and sound to help you drift off to sleep, and the Smart Snooze feature that lets you snooze by tapping anywhere on the body of the unit instead of having to press a button. These three features are not on the non-Plus model, which has a regular snooze button instead of the Smart Snooze feature.

Philips advertises that this alarm clock offers "light therapy" that can boost "your energy", "improve your mood", "energizes morning wake-up", "gets you out of bed faster", and "helps you fall asleep". While it can certainly help attain those goals, I think that for many people, getting a good night of sleep and feeling well-rested the next morning has far more to do with the number of hours that they sleep, their mattress and sleep environment, what they do during the hours before bedtime (e.g. minimizing alcohol and coffee consumption), possible issues with insomnia or sleep apnea, etc. far more than the kind of alarm clock they are using. Philips juggles the word "light therapy" with this product, but this is *not* a product that utilizes blue light therapy to treat SAD (Seasonal Affective Disorder).

I had mixed feelings about rating this product (which I really rate as 3.5 stars).
