DESIGNED TO BREAK. USER CANNOT CHANGE LIGHTBULB. UNACCEPTABLE

Reviewed in the United States on August 29, 2018

Verified Purchase

The manufacturer conveniently forgot to mention that you cannot replace the lightbulb. I am not interested in purchasing a product that is deigned to make you a repeat customer when the lightbulb breaks. The LED lightbulb will expire at some point. That is a fact. For environmental, moral and financial reasons designing a product that you the user cannot replace when it goes out is unacceptable. A new LED bulb is going to be a few dollars. If they seal the unit shut and make it to where you will just have to purchase a entire other unit is perfect for them to ensure the product will break and you will need to buy another one. Sorry I am not going to be part of purchasing something that contributes to a wasteful consumer market. I do not wish to throw this out into the landfill when the bulb goes out just to purchase another one. They say that for safety reasons the user cannot change the bulb. Sorry that excuse dosent fly with me.

This thing is perfect. I'm reading more

Reviewed in the United States on February 2, 2018

Verified Purchase

This thing is a game changer! I got it because I got tired of being owned by my phone. It used to be the last thing I checked before going to bed, and the first thing I would check in the morning.

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.

Worked Amazing, Great Hardware - Awful Controls

Reviewed in the United States on November 7, 2017

Verified Purchase

Waking Up: Amazing. 10am wakeup to 07:20am. And I don't wake up cranky as **** either. To be blunt, I got fired from a job because I wouldn't wake up and I was having no success waking up earlier no matter how much I wanted to - this thing is a career saver for me.

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.

What's Bad:
- 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.

The clock light doesn't dim. At first I thought that there was something wrong with the device but then I noticed that the brightness of the clock in all 4 brightness settings is very similar. I will have to put a sticker there.

Okay, but not as fantastic as promised

Reviewed in Canada on November 29, 2017

Verified Purchase

Works okay, as any good product should do.

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.

There are some things I like about it

Reviewed in Canada on February 25, 2018

Verified Purchase

I've had this alarm clock for a few months now. There are some things I like about it, and some things I don't. For starters, my room has black out curtains so no light gets into it. I can see this light not being beneficial to people who have brighter rooms/no black out curtains.

Pros:
-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

Cons:
-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
-It's expensive
-It's ugly

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.

Not effective for advertised purpose and poor design.

Reviewed in Canada on August 4, 2018

Verified Purchase

Seems like a good idea, but after a year, do not find it really helps in terms of my sleeping. Work shift work and it is getting to me, this provides no benefit in terms of ease of waking up or feeling better and more alert during the day. So far would just be a 3 star but also the buttons are small and around the rim with no labeling. Easy to hit the wrong button. I use it all the time and still occasionally hit the wrong button. If the wife has to use it which only happens if I leave it set for the wrong time she just unplugs it to shut it off. The only easy thing to do is snooze which is tapping the front screen. Would never recommend this product. A lot of Phillips products seem to have this, good idea destroyed by poor functionality (in this case the good idea does not really pan out either as no waking benefit from using the product).

I love this alarm clock!!!!

Reviewed in Canada on October 31, 2016

Verified Purchase

No more using my phone for an alarm and pressing snooze half asleep without even thinking. With this alarm I always wake up before the sound even starts. I am usually confused as to why I am waking up and it takes a few seconds to notice the light. But it's MUCH easier to stay awake and not roll over and go back to sleep. It really does help you wake up ready to go. As I write this, it is 6:10 am and I woke up 20 minutes ago by the light. I didn't even need the sound. And now I feel ready to jump out of bed and face the day instead of that awful feeling of having to drag yourself out of bed. You still need to get enough sleep though !!!! No magic cure for that! I also love the features on the alarm clock. The only thing I was disappointed about was there not being a feature to turn off the time display when you sleep. You can turn the brightness down very low but I am all about total darkness when I sleep and think they could have maybe made a feature where the time fades off and you can just tap the surface to see what time it is. But... overall very impressed with this product.
