So How Does the Philips SmartSleep HF3670/60 Work?

Founded in Eindhoven in Holland in 1893, Philips employs more than 75,000 people in over 100 countries around the globe – making them one of the biggest electronic companies in the world.

Philips made their first wake-up light in 2006 and since have continually evolved their brand. The Philips HF3670/60 was released in 2017.

So let’s jump in:

The sunrise and sunset simulation can be set for a duration of 5 to 40 minutes – the default is 30 minutes. It also has a number of other personalisable settings including sound and light intensity and it has four different sunrises you can personalise. The SmartSleep HF3670/60 also allows you to control all of these settings via the SleepMapper app on your smartphone.

This also has something called AmbiTrack monitoring, which are sensors that measure your bedroom’s temperature, noise, light and humidity levels – you can see the information on the app and get suggestions on how to improve your sleep.

Pretty cool right?

It comes complete with light guided breathing exercises, designed to help you relax and wind down and get to sleep by following a series of light or sound patterns. It also has a PowerWake alarm which will kick in and definitely wake you up if the light/sound doesn’t!

There is also the option to wake up to nature sounds, relaxing music or FM radio – with the sound starting at a low level and gradually building up to pre-set level your determine. And you can set multiple alarms for different days of the week or weekend.


It has power back-up for eight hours, an AUX port so you can turn you attached your phone or tablet and turn it into a speaker and a USB port to charge your phone.

The Good

First things first:

Philips seem to find ways of continually improving the quality of their simulated sunrises/sunsets and they have managed to do that again with the SmartSleep HF3670/60.

This actually offers four themed sunrises you can wake up to each morning – these are Carribean Red, Nordic White, Island Red and Sunny Day. It is a great addition and all of these themed sunrises are really nice and fully customisable.

The light always feels natural, warm and has a lovely smooth glow and transition from darkness to light.

In short – they have stepped up their game again.

What is more:

Philips have also improved on the nature and ambient sounds. They are very good quality, and start off softly and gradually increase in sound to your pre selected volume.

There are eight sounds in total, plus FM Radio, the sounds are:

  1. Forest birds
  2. Summer birds
  3. Buddha wakeup
  4. Morning alps (cows and bells)
  5. Yoga harmony 
  6. Nepal singing bowls
  7. Summer lake (essentially ducks quacking and swashing around)
  8. Ocean waves 

The bird sounds are particularly impressive – with an almost 3D like quality, as if the birds are all around you.

In addition the radio quality is exceptionally good.

And here is another thing:

Note the title of this sunrise alarm clock – the Philips SmartSleep Connected Sleep and Wake Up Light – the key word here is ‘Connected’.

Essentially, unlike previous models, you can control everything here via your smartphone by downloading the SleepMapper app.

So via your phone you can set the sunrise and sunset themes, alarms, sounds, durations, etc, etc. The app is easy to install and works well – making it much easier to control the light.

It also allows you to input personal data, and generates details on your sleep patterns for you to help you sleep better.

It is a really nice upgrade, but don’t worry, you can still control almost everything using the built in screen on the unit.

Add to this:

This also has something called an AmbiTrack sensor built in. This measures four factors that are required for a good night’s rest – temperature, humidity, light and noise levels – and you can view all this information on the SleepMapper app.

This data is built up and suggestions are made as to how you can improve your sleep patterns.

Pretty impressive right? 

You are dead right!

This also has a sleep tracker that gives you an understanding of your sleeping patterns and how you can improve them – so it measures your time in bed and your sleep. By using this in conjunction with the AmbiTrack feature you should be able to improve your sleep and accordingly make a difference in how you feel throughout the day.

The RelaxBreathe Function is a doozy too – the perfect way to unwind at the end of a stressful day.

Essentially these are a series of breathing exercises, using sound and light or just sound to help you relax and fall asleep.

You replicate the breathing patterns by following the sound and light, set to a duration of 5 to 15 minutes.

Don’t believe that will work? Just give it a go!

Worried that you won’t be woken up by a gentle sunrise? Then fear no more as another new feature the HF3670/60 utilises is a ‘Power Wake’ alarm.

So if you don’t wake up, or if you snooze too long, you get the blaring sound of a traditional alarm clock and it flashes through a spectrum of bright lights. 

It won’t fail to wake you up and is a nice back-up feature!

Something other things I like:

You now have the option to set two alarms and completely customise the profiles for them (ie time, light intensity, wake-up duration, sound and volume, etc) and you can have them both on together or independently.

The screen display is clear and easy to read. It can also be adjusted and set to ‘0’ at night if any ambient light disturbs you.

You can use the USB charging point to charge up your phone or tablet, the time is automatically synced and it has an eight-hour battery backup just in case there is a power outage.

The Bad

My main issues with this are setting up and connecting with the WiFi.

This uses a 2.4 GHz network – which by now is all but redundant – and you have to be on the same network, so there will be a lot of switching back and forth between networks as most devices use 5G now not 2G.

You can also only connect a single device to it and you have to be on the same WiFi network, so you cannot control it off site so to speak.

Also if you don’t give permission to the app to store your personal information then it renders the majority of the functionality useless.

Beyond that:

If your phone breaks, or you get a new one, you literally have to reset the device and set up your personal profile again, which takes a little time. This makes all the registering and setting it up initially almost pointless, I am confused as to why you can’t just log in using all the details you set up on a new phone. But you can’t.

End of story.

Other qualms include the fact that you cannot use your phone to wake up to your own music and that this wake-up light is quite large – so it will take up a fair bit of space on your night stand.

Finally – this is expensive, there are no two ways about that. It does have a lot of functionality, but if you don’t need the connected smart features this offers then you might want to consider the cheaper version.

The Beautiful

Despite it’s bulky size this looks rather nice, almost like a modern sculpture, with a good build quality it will look rather nice in your bedroom.

How Does It Compare to Other Philips Models?

Essentially the main differences with this and the Philips SmartSleep HF3650/60 is the ‘connected’ feature that allows you to control this via your smartphone and the AmbiTrack sensor.

In addition to that:

This also has the PowerWake alarm feature, four sun themes as opposed to one for the HF3650/60 and eight wake up sounds and four relaxation sounds (as opposed to seven and three for the HF3650/60).

And Does it Work?

Yes it does! According to Philips:

  • 92% of users find it easier to get out of bed based on independent research, and;
  • 79% of users report they fall asleep easier using the RelaxBreathe function after two weeks of use.

You can read more about these claims on the Philips website.

There is also plenty of positive feedback when you look at the reviews of this wake-up light, with users saying they fall asleep more easily, wake up naturally, feel refreshed and have much more energy throughout the day.

Research has proved that wake up lights have a beneficial effect on sleep, waking, mood and energy. There are numerous studies proving this but here are just a few:

My Verdict

My Rating - 91%


Some amazing features

This takes all the great features of the SmartSleep HF3650/60 and adds to them with the ability to control everything via an app, four new themed sunrises, the AmbiTrack sensor and the PowerWake alarm.

So all-in-all this is more than just a wake-up light, as it has many other features that can benefit you but the actual sunrise/sunset feature is fantastic, and gloriously smooth and warm.

The only real downside to this is the price point which is high, and if you don’t need to control everything via the app you are better off going with the HF3650/60.

So yes it is an investment, but if you have sleep issues this could be a lifesaver for you and will be worth it.

Other Options

If you don’t need the option to control your wake-up light by a smartphone then you can go for the Philips SmartSleep HF3650/60 or even the Philips HF3520 which has less functionality, but still a beautiful sunrise and is cheaper still.
