    • Sunset Simulation!
Size: 1 Count (Pack of 1)
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. However, the true bonus turned out to be the pleasant efficacy of its sunset simulator go-to-sleep feature.

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. ... show more

    • A worthy alarm clock upgrade
Size: 1 Count (Pack of 1)
Why did you pick this product vs others?: I previously had a cheap sunrise alarm clock (Winshine) that did a decent job, but I didn't like that the light it gave off was so white and that I couldn't adjust the brightness of the display. I could get over those downsides, but now with a baby on the way and needing a darker bedroom with softer, red light, I decided to upgrade to the Philips SmartSleep alarm clock. And I am upset that I didn't upgrade sooner! The Philips SmartSleep alarm clock has a much more pleasant light and wonderful features (red-tinted and dimmable display, sunset mode, highly adjustable volume and brightness levels, two saved alarms, and radio). I didn't find it that complicated to get set up; you just need to read the instructions, and it takes maybe 10 minutes. I highly recommend the Philips SmartSleep - I think it's well worth the price! ... show more

    • THIS IS THE ONE! (After DAYS of research of reviews and recommendations.)
Size: 1 Count (Pack of 1)
I live in a room that has no windows, so I have no sunlight come into my room. For the longest time this made waking up for me very difficult, especially during the pandemic when I was forced to work from home and didn't really have a routine. I saw the price point of the alarm clock which was much lower than some other alarm clocks on Amazon that also have the artificial sunlight feature, so I went ahead and bought one. I was really surprised at how well it works. Set-up was very easy, it only took me about 5 minutes to unbox the alarm clock, set the time, and set two alarms. No other set-up is required unless you're wanting to set up extra features from the get-go, but I only bought the alarm clock for the artificial sunlight. Controls feel a little strange at first, but are easy to learn and get the hang of. I still have the manual but I haven't looked at it after I first set my alarm clock up. The artificial sunlight works great and the light it produces looks very natural. It's also nice that you can set the sunlight to start anywhere between 10 - 60 minutes before the alarm goes off. The light will start at a dim red and will gradually become brighter as the alarm gets closer to going off. I have my first sunlight set to start 60 minutes before the alarm goes off and I find myself waking up a few minutes before my alarm goes off everyday. The artificial sunlight really helps, and on most mornings I feel well-rested when my alarm goes off instead of confused and groggy. The alarm clock has some extra features built into it, such as a radio player, different colors of light you can make it shine (other than yellow for sunlight) for mood-setting in your room if you wish, and a sleep mode. I haven't really dabbled in the other features besides the sleep mode, so that's the only extra feature I will review. Sleep mode is something you can set up on a given night, and it allows you to set up a light that starts off bright but then gradually gets dimmer (basically the opposite of the artificial sunlight for the alarm), as well as play a loop of a sound for a given amount of time, and the sound can play for up to two hours (though you can of course set the amount of time that the sound plays for). There's only three sound settings available for the sleep mode to play: Rain drops, river, and campfire (which plays fire and cricket noises). You can also set the radio to play for sleep mode if you wish. I've found the sleep mode helpful on occasion, and it's a great extra feature. The only downside is that there's only three different types of sounds to play for sleep mode. More variety would be nice, but for an extra feature built into the alarm I can't really complain. Sleep mode also does not re-occur every day like alarms, it's something that you have to set up manually for each night you want to use it. This is actually something that I like because I don't use sleep mode every night, only on occasion. Two quick things I want to mention is that while the alarm does not connect to the internet, it does have built-in memory, so if you unplug the alarm the time on the clock and any alarms you set up will be saved once it's plugged back in. The brightness features for both the alarms and sleep mode are also optional, as well as any sounds associated with them. So for instance, if you just want to be waken up by the artificial sunlight but don't want to have an alarm sound to go with it, then you can set an alarm up to not play sounds. And for sleep mode, if you don't want a dimming light to be on your alarm clock, then you can turn that light off and just let soothing sounds play. Overall, this alarm is great for the value and quality, and I'm happy with my purchase. It also comes packed with features that I didn't even consider or care about prior. Pros: Great price, great natural artificial sunlight, great extra features like mood-setting lights and sleep mode, semi-large plug-in cable, easy-to-use buttons and set-up, charging port in the back of the alarm to charge devices like phones (this is very useful if your night stand doesn't have a charging port close enough by), a lot of customization options for alarms, sleek design, built-in memory, optionally allows batteries to be put into the bottom of the alarm so that it will continue to work during a power outage. Cons: No internet connectivity, meh sound quality, not a lot of sound loop options for alarms or especially sleep mode. ... show more
