- 5 Natural Wake-up Sounds & FM Radio
Coloured Sunrise Simulation
Inspired by nature’s sunrise, light gradually increases within 30 minutes until your room is filled with bright yellow light. This process of increasing light mirroring a sunrise, stimulates your body to wake up naturally. By the time light has filled the room your chosen natural sound is added to complete the gentle wakeup experience, leaving you ready to Rise and Thrive for the day ahead.
5 Natural Sounds
At your set wake up time natural sound will play to complete the wake up experience and ensure you are awake. The selected sound gradually increases in volume to your selected level within one and a half minute. There are five natural sounds you can choose from: Bird Song, Birds in the forest, Zen Garden, Gentle piano and Seaside Sounds.
Listen to your favorite radio show while you are waking up.
Intuitive Dimming Display
The brightness of the display adjusts itself. If the bedroom is filled with light, the brightness increases to keep the display readable. When the bedroom is dark the brightness dims so it doesn’t light up your bedroom when you are trying to sleep
A slight tap anywhere on the Wake-up light, sets the snooze mode. After 9 minutes the sound will gently start playing again.
Proven by scientists
At this moment in time the Philips wake-up light is the only one scientifically proven to work. In order to make the Wake-up Light the best possible product it can be in genuinely waking you up naturally and energized we have done a lot of clinical research. This research was conducted by independent science facilities to study and prove the effects of the wake-up light on the overall wake up experience. This way we have proven, among other things, that the Philips Wake-up Light not only wakes you more naturally, but also more energized and that it improves your mood in the morning.
Philips was founded over a 100 years ago as a company that produced and sold lightbulbs. Over 100 years Philips grew into a global company that brings innovation in lots of different areas. To this day lighting still is the soul of Philips. The Wake-up Light is proud to continue its heritage by building on years of knowledge and expertise of the world's most well know lighting expert.
Sunset simulation is a light therapy used before you go to sleep. Sunset simulation prepares your body to fall asleep by gradually decreasing light to your set duration.
Inspired by Nature's Sunrise, light gradually increases within 30 minutes from soft morning Red through Orange until your room is filled with bright yellow light. This process of changing an increasing light stimulates your body to wake up naturally. By the time light has filled the room your chosen natural sound completes the wake up experience, leaving you ready for the day Ahead.

No more. Now I can leave the phone charging across the room (or in a handbag even. Who cares?) I can set this for the "sun to set" at 15, 30, 45, or 60 minutes later. So I set it, and I get in bed and read a book for an hour. Then the "sun goes down" gradually, and I go to bed. Eight hours later, the "sun" starts coming up gradually. So gradually, that at the beginning, you don't even notice. And you can set sounds in addition to the "sunrise" effect: birds chirping, ocean waves, classical music, or FM radio (although why on Earth would you choose FM radio?)
You can set two different wake up "alarms". It doesn't even feel right to call them alarms, because it's not obnoxious or loud. It doesn't jolt you awake. You wake up gradually. This thing is perfect. I'm reading more, sleeping a lot better, and I don't even remember anymore to grab my phone to check social media in the mornings. In fact, sometimes I'll be at the office, and it'll be noon before I realize I left my phone in the car.
Drop the dependency on cell phones. It's ridiculous. We're like that movie, Wall E. Get this and improve your life and your quality of sleep.
Hardware: Everything is done well.
- The night light puts out a soft sleepy light that's bright enough to read by but makes me sleepier rather than more awake like a lot of lights do.
- The radio speaker puts out soft sound that's relaxing to listen to (in contrast a lot of speakers put out tighter sharpened sound that's exciting and clear but not sleep inducing).
- The clock is amazingly non-disturbing. I didn't think anyone could make an led clock that didn't keep me awake when next to my bed, but this one does the trick. And I didn't even turn the contrast down.
- Sticky rubber keeps it from sliding around.
- It looks fine. Philips has a new model that...uh, it doesn't look good. This one looks fine next to the bed.
- Controls are just awful, like other reviewers said. The buttons are located around the edges and it's difficult to find the one you're looking for. It took me a while to just figure out how to turn the alarm off. This is despite that it comes with a touch screen and menu. Everything is work to figure out how to do it, you really need the instructions that come with it. Despite this I'm not sending it back - you can figure out the controls - but as someone who does tech work all day it still took me 30 minutes to figure out how to do stuff on this.
- The sound part of the alarm turns itself off after 60 seconds. Wth.
- It's easy to hit the alarm control by accident which disables the alarm until you turn it on again.
- No line in or sd card slot for your own music.
- No automatic day/weekend switch, as the device doesn't even know the date.
- You can really really dim the clock but cannot turn it off completely. Not a problem for me, but I can see why it could be for other people.
- An electrical outage won't lose your alarms or settings, they're saved. And if the power comes back on it will resume the alarm still waking you up at the correct time. And the clock stays accurate through a power outage as well. However, if the power is out when your alarm it will skip it. Seems odd for such an expensive device.
My advice to Phillips is to stay with the physical design, but move all the physical controls to the menu/touchscreen. And fix the other annoyances I mentioned.
I'm so relieved to find a decent light that I'm keeping this and not returning it, but because of the horrid physical controls I cannot recommend it to other people. If it had good controls I would have bought it as a christmas present for other family members who also suffer from sleep issues, but I just can't see myself giving out something with such horrid controls.
Top international reviews
I had strong expectations regarding this product, being convinced by multiple raving reviews on Lifehacker and on this very website.
In reality, if the lamp does light up as expected, it doesn't wake me at all ! Even if oriented directly toward my face. Nothing. Moreover, it does not soften at all my spirit and energy when my secondary backup alarm finally wakes me. Finally, the ligh is nowhere near as a real sun. It rather looks as if an 80' disco lamp was put on the floor. It looks gloomy in my room.
Setting buttons and touch-panel are both cool but not easy to use in when lying in bed. In this position, setting buttons are behind the clock, so invisible for user, and touch-panel are too close to table to be easily accessible without standing up a bit.
Bummer, the lamp has not backup battery, so in case of temporary electricty shortage, all settings and time are lost.
The product is not bad, but I'll return it as it is expensive and offers little value for what it gives to me. As I do appreciate however to wake up not in the total dark, I'll purchase a much less expensive socket timer do to the same.
-You have the option of light only alarm (which is what I use)
-You can choose how bright you want the light to go as it brightens
-You can use it as a lamp and again choose how bright you want that
-Dimmed time numbers at night
-A selection of times you want the sunrise to last
-The button to turn on the lamp is put in the center of the brighten and lighten lamp buttons. In the middle of the night the button is hard to find and I end up hitting multiple other buttons including turning on the radio.
-It is round, with a not larger enough base, I've knocked it a few times to have it start to roll around my night stand
-I hate the touch screen buttons to set the clock on things, they are difficult to use
-No battery back up if the power goes out
-Limited selection of time you want the sunrise to last
Over all I can't say it has helped me wake up in the morning. It does wake me up, it doesn't motivate me to get out of bed without the second alarm on my phone going off three times.
Is it worth the hefty price tag? I’d argue yes. But it does have some cons including buttons that are hidden and hard to find, especially in the dark, and an instruction manual that isn’t nearly as thorough as one would expect.
I keep it on a dresser about 5 feet from the foot of my bed so that I have to physically get up to shut it off. I was a bit worried at first whether it would be bright enough from that far away, but it has more than enough power to light up my room and wake me up despite not being beside my face as suggested in the instructions. This also gives the illusion of the sun rising/falling at the foot of my bed, which is gives me a sense of fun and excitement that no alarm clock has any business doing.
The transition from red through orange to yellow to white is perfect. It works exactly as described, slowly and gently easing you out of sleep so that by the time the alarm sounds go off, you will wake up feeling rested, alert, and ready for the day. The reverse light transition in the sunset function works equally as well. I use a Joovv red light before bed every night which usually puts me in a state of deep sleep, but the sunset function is a fun little bonus to add on top of that.
Definitely worth buying if you want to wake up feeling better in the dark winter months, or just don't want to wake up to a normal alarm clock.
PS. I've seen the question asked whether you can turn off the clock completely. Maybe mine is just newer than some of the old ones that say you can't turn the clock off, because mine it is entirely possible. I turned the clock off right away (just set the brightness to zero), so my room is completely black at night.
The light portion of the alarm works well if you are facing the light when it goes off. The problem I found which I never really thought about before buying is I change sides I sleep on through out the night. If my back is to the light it of course doesn't work.
I changed the alarm to the radio instead of calming noises thinking it would help but for the price of this product I could just buy a radio alarm for a fraction of the price.
The other downfall which I would have ignored if the light worked really well is how big and ugly it is. There is no way to make this light blend in or look good on your bedside table.
