Review: A Much More Natural Way to Wake Up - The Philips SmartSleep Wake-Up Light has genuinely improved my mornings. Waking up to gradual light instead of a sudden alarm makes a noticeable difference. Wake-Up Experience The light slowly increases in brightness, which feels far more natural than a harsh alarm sound. I wake up feeling calmer and less stressed. Light Quality The light is soft and pleasant, not blinding. It fills the room gradually and makes waking up feel more relaxed. Daily Use It’s easy to set up and becomes part of your routine very quickly. Ideal if you struggle with dark mornings or abrupt alarms. Final Thoughts A great product for improving sleep routines and mornings. Once you get used to waking up this way, it’s hard to go back.
Review: Just about perfect - I’ve used a Phillips wake up light for the past 12 years or so, and finally that old one gave out. Not the light, but the sound. So I figured I’d get a new one. First I bought a cheap non-Phillips one that turned out to be a disaster, so I decided on a proper Phillips one instead. I’m happy to see the new features added in comparison to my old one. Features I especially like: - the midnight function: if you need to get up in the middle of the night simply tap the top of the light and it will give a tiny amount of red light. Just enough to find your way and not stumble over clutter and breaking your neck. Very much appreciated. - ULTIMATE BRIGHTNESS!! The highest brightness level is seriously bright. No way you won’t notice that. - very dim clock light. I need my bedroom to be as dark as possible. Most electric alarm clocks have a clock light that is annoyingly bright, making it difficult to sleep. Luckily this light has a very dim setting, making the clock just visible at night. During the day it will not be very visible probably, but that’s fine. You can also turn it off if they want. - snoozing only stops the sound. The cheapo light I bought also stopped the light during snoozing which is just stupid. - the touchscreen can be quiet. By default it make a small sound, but you can turn it off. Using the menu is easy and straightforward. No idea why it is designed to look like a ceramic sink drain, but you can’t win them all I guess. All in all this light is just about perfect, sink drain look and all.

## Questions & Answers

**Q: does this vibrate? what girth does this take?**
A: It doesn't vibrate.  It's a lamp.
It's quite wide.

**Q: This says it has an 'advanced alarm', so does it allow you set alarms for week days but not at weekends ?**
A: No. But it is easy to reset the alarm for a lie in at the weekends.

**Q: What is the hole for ?**
A: Hi there, thanks for your question. The hole in the middle of the device is purely a design decision, and it doesn't have a very secret function. ;) I hope that helps, but please know that my colleagues and I are happy to discuss any additional questions with you. You can get in touch via Facebook (philips.to/UKFBMessenger), Twitter (philips.to/UKCareTwitter) or phone (philips.to/UKContact). 

Cheers, Max.

**Q: On the Philips website it says that you can set 2 different alarm times, but I've read here that you can't. Please can someone clarify this?**
A: Hi there, thanks for your question and interest in the Wake-Up Light! I looked into it, and it is indeed possible to set two wake-up profiles. :-) I hope this helps and please let me know if you have any other questions, I'd be happy to answer them. Cheers, Chase.

### ⭐⭐⭐⭐ Primarily a clever, if expensive, bedside light.
*by B***A on 4 March 2025*

An intriguing device from Philips that should be thought of as a clever light which offers sleep, wake-up, and relaxation modes and sounds. There’s also an FM radio. What it does best is a light. It feels like a quality luminaire and can go very bright but as a larger light-source it’s not as intense on the eyes as a point like bulb. And it’s party trick is the midnight light. In a dark room it’s like red sunset and easy on the eyes. This night light is simply activated by just tapping the top rear of the unit. These things aren’t easy to photograph as the camera picks up the LED refreshing so apologies for the quality with the light activated. Other things to note are that functions are accessed by touching icons around the clock area and the clock auto dims and brightens depending on lighting conditions. As for the sound quality, as a rear firing speaking it’s not going to set an amazing standard in audio but it’s acceptable. It also doesn’t go too loud and isn’t the cleanest sound - not great for the hard of hearing - but if not too far from a wall this helps to improve the volume. Overall this is primarily a light with audio bolted on.
