SmartSleep Wake-up Light, Colored Sunrise and Sunset Simulation, 5 Natural Sounds, FM Radio & Reading Lamp, Tap Snooze, HF3520/60

This is the second Philips SmartSleep Light i've owned. My first lasted me a LONG time; and waking up to light is a game changer in regard to overall sleep quality. No loud noises; you can choose a birdsong or your favorite radio station to ease you awake; and this is an option under the Menu; in case the emerging 'Dawn' doesn't do the trick. I've never had to use anything more than the light source. Many of my friends don't believe that a light can wake you! But I say they don't know what they are missing. Once you understand the science behind Dawn Simulation you will understand why this is best for your sleep - wake cycles. Especially in the dark winter months; you can train your body to still believe it's spring! Magically. I like all the Menu options available; you choose when and how you want to wake but one of the really amazing features of using a Dawn Simulator is that you are also able to use it as a Sunset at night when you may want to read in bed to relax you into sleep. This is a unique and amazing feature; you set the timer for Sunset; and tuck yourself into bed - the light is brighter and very very gradually begins to fade into 'sunset' and dark. Your brain is easily and happily relaxing into sleep! I love this feature. The clock comes with a very easy to understand User Manual - and there are several Timers options you can use as well. The color quality of the Philips is excellent; soothing and bright IF you want it to be - you make the choices as to the amount of brightness you need or want. I'd HIGHLY recommend this product.

This is such a good alarm clock! Easy instructions, easy setup, and it truly does make a huge difference in waking up in the mornings. You can choose multiple alarm sounds, adjust the brightness of the "sunrise", and it even has a bedtime feature! We were skeptical of how much we would actually like this, but we couldn't function without it now! Definitely worth the purchase.

I have a very difficult time waking up in the mornings. This alarm has helped me some with that problem. It's not a miracle, but it's the best I've found so far. I will not blame the alarm clock for my "waking up disorder". The sunrise simulation is pretty helpful for making the wake up process a litte easier. I believe if it can wake me up, it could probably wake most people up. The light simulates a sunrise (both color and light), and gradually gets brighter leading up to your set wake up time. So, by the time you are supposed to wake up, your room is *brightly* lit up (you can set the brightness level). Personally, I have found that sometimes I feel a littel cheated out of my extra 30 or so minutes of "extra" sleep some mornings if the light wakes me up a little early as it "rises". Also, if you are a heavy sleeper or are very tired, you might just start covering your head with your covers to avoid the light- thus making the light a little less helpful. Another thing, I find the natural sounds to be a little too soothing/relaxing to really wake me up, and the only other option is the radio (which is usually annoying in the early am/ talk, and not music). It would be nice if there was an aux input or cd, but there is not. It does have dual alarms, which is a good feature. A warning, It is very easy to snooze this alarm- you simply touch it, which I am a master of, on any alarm- but especially on this one-it's like magic (and FYI, the light remains on, even when you snooze/touch it, which is helpful, unless you covered your head). I still set my phone alarm as a back up, just in case I snooze completely through the alarm- which is rare.. I do wish there was a battery back up. For this price, you would think it would keep time/wake you up after a power failure. Overall, I think this is a nice alarm- it looks good on the night stand, and the light is fantastic. It does help you wake up, even those of us that have a difficult time doing so.

Purchased: 2016 Age: 10 yrs going strong This has been the best addition to my lifestyle, completely changing how I wake up. Since changing to using a wake up light, I wake up more easily, and feeling more well rested (as you’re woken gradually not suddenly). It especially helps during the winter months. If you’re looking for a reliable, long-lasting alarm with a gradual wake-up and calm-down light, this is well worth the price. It’s very bright and has a simple selection of pleasant nature based alarm choices. The make and quality are exceptional, with a solid build that feels dependable. It carries strong brand recognition, which gave me confidence in my purchase, and it has certainly lived up to the reputation. Over ten years, the front buttons have only darkened slightly, and it still looks and feels almost new. In the last year, I’ve noticed the side buttons occasionally need an extra or firmer push, but everything else works perfectly without issue. If you are on the fence - just do it, you will not regret it!

Gentle wake up from the light instead of startling alarm clock. love

Originally purchased my Philips SmartSleep, years ago, in order to awaken with light and it does a great job of this. However, the true bonus turned out to be the pleasant efficacy of its sunset simulator go-to-sleep feature. Imagine a light that not only dims over time but also reddens as it dims, and goes through the sort of pinkish-orangish red reminiscent of beautiful sunsets, providing a pre-sleep ambience whose gradually diminishing intensity and simultaneously increasingly red hue does indeed physiologically prepare you to go to sleep. Another Philips SmartSleep plus is that it has intuitive integral controls, ideal for simply winding down without needing to use a screen and/or app in order to set it. While app-based products may offer more proverbial bells and whistles, they also inevitably lengthen the time required to get to sleep... sometimes even defeating the purpose via temptation for just one more text/email message, just one more social.media refresh, just one more news scroll-through, and so on, for however many minutes or hours. The only thing that could be better about the Philips SmartSleep would be if it had a touch-to-activitate nightlight mode, whereby touching anywhere (or, at least, a very large and centrally located button) would either provide a dim reddish light or turn it off. Although easy enough to turn on and off using small buttons while one is awake, this isn't necessarily ideal human factors engineering for the semi-awake, semi-coordinated. Finally, other than this potential improvement, the Philips SmartSleep is well-designed, effective, well-made, and well worth the nightstand real estate it elegantly occupies. While initially shopping, opted for this based on its features, design, and manufacturer -- a decision that has thus far resulted in several years of reliable usage. And, as mentioned, purchased to enable waking-to-light, and soon found that its *sunset* simulation sleep feature was just as pleasant, if not perhaps more so, than the sunrise simulation wake-up. Dividing its cost by the number of days in use, and considering the value of waking up to light, plus being able to add sunset simulation as a pre-sleep cue, Originally purchased my Philips SmartSleep, years ago, in order to awaken with light and it does a great job of this.

Since it's used daily, this product's cost became rather negligible over time (price divided by number of days over however many years), and its reliability has proved positively priceless.

I’m the type to look at many different products before buying and selected this one for the trustworthy brand name. It was definitely on the pricier side but hoped it would last a long time and be worth the price. Was hoping this clock would be a nice wake up for my child and gave it a try for about a week. However 2 main reasons are giving us cause to return. 1st and main reason is that the sunrise light is so bright that it is hard to see/find the right button to turn it off in the dark morning. Perhaps if the design was different so the off button is much bigger or placed somewhere else, it would be better. Child said it hurt their eyes to turn it off. Im sure after a while we would know exactly where the button is but kid said it hurt to even look towards the clock to walk to it to turn it off (clock placement was on a bookshelf across from their bed). 2nd, and this may just be us, but the sunrise simulation will start at least 20 min prior and my child must be light sensitive because they would wake up before the set time. We tried to adjust to this by setting the actual alarm time much later so they wake up when the light starts getting brighter but then realized the alarm sounds become useless since they are already awake. Love the idea but would like other options for it like a more immediate light wake up option (maybe a faster dim to bright option like the demo) for the price point. I feel it could really be helpful for some people however for the 2 reasons stated above, it didnt work for us. If those 2 points were changed (off button placed elsewhere or much larger, shorter wake up light time), we may have considered keeping it. For the price, it just isnt worth it for us.

works well. fairly easy to program. light brightness good. sundown feature nice. sound for going to sleep good. ascending alarm sound with a few choices. easy snooze feature. Significant negative for me is they design with the buttons for the alarm, lights, sound...they are difficult to find when reaching over from bed and difficult to press without moving the whole lightweight device. Wish this was better from phillips-especially for price. Have to depress alarm button(s) to turn it off; so have to depress it again each day in order for it to alarm for the next morning/time. Does default to previous set time, so that's good. Have been using a much older phillips model...prob over 10 years. Continues to work well but was larger, less modern looking and had less features than current model so decided to replace it.
