For those that have already used a natural light alarm clock will already be familiar with their benefits. A regular alarm clock, even when the sound starts low and builds can often shock your body out of sleep. This can have a measurable effect on your mood and energy levels. Alternatively a gradual light alarm clock will bring you gently to a place where the sound will not jolt you. This is especially useful in winter months when it’s still dark in the early hours.
There are many different types of natural light alarm clocks available, but only a few that have the dawn simulator color changing feature, of those I’ve tested, the Philips HF3520 wake up light is by far the best.
Philips HF3520 dawn simulator alarm clock – Design
The HF350 Philips Wake up light is very similar in shape and design to the rest of their natural light alarm clock range.
For an alarm clock with so many features and settings, the HF3520 is exceptionally simplistic in its design.
Philips HF3520 dawn simulator alarm clock – Features
- Dawn Simulator, Sunset and Sunrise settings – The Philips HF3520 features color changing LED lights that go from red to orange to yellow or back the other way, should you wish to use the alarm clock as a night light that will gradually darken like a sunset. Both the sunset and sunrise features can be set to a specific time preference.
- Intuitive dimming display – This is a really clever feature, the brightness will automatically adapt depending on the natural light in the room
- Tap to snooze function – No need to hunt for the snooze button, the Philips HF3520 is touch sensitive no matter where you make contact. The snooze can be used twice and has a 9 minute interval.
- Natural Sounds or FM Radio – The HF3520 comes with 5 natural sounds which will gradually increase in volume once the dawn simulator has reached its brightest setting. The maximum volume can be set and will increase gradually over 90 seconds. The sounds include song birds, gentle piano music, the ocean, a zen garden and the sounds of a forest. The FM radio is also a nice feature, but I’d never use it just because you cannot be sure what’s going to play. It doesn’t matter how amazing this Philips wake up light is, if you are woken by a Justin Bieber track it’s not going to be a pleasurable experience.
- Adjustable Reading Lamp – With over 20 different light intensity levels the HF3520 makes a very practical bedside reading lamp.

Where I’m from the days are really short. I can’t bare to wake up in darkness every morning, it really does effect ones mood 🙁 Since I’ve been using the phillips wake up light (I have the one with the sunrise simulator) it’s made a huge difference.
Hi Mary,
Thanks for your comment, the Philips wake up light on a dark morning does make a big difference, so much nicer than opening your eyes to darkness.
It’s worth paying the extra for the HF3520 model, the other Philips wake up light models don’t have that nice red glow that this one has. I don’t often see the red glow in the morning though as I’m still asleep most of the time at that stage, but it’s nice to drift off to sleep in the evening with the sunset simulation.
Bought one for my husband, he gets up before the sun rises, and is always grumpy. It seems to have made big difference. I barely ever hear the alarm sounding, where as before I’d have to literally shake him before he would turn the damn thing off.
Hi Jess, thanks for commenting, I guess the Philips Wake up light is also handy for the partners of the early risers too.
Thanks for the review.,
It would be good if Philips brought out a wake up light with a DAB radio and bluetooth audio streaming built in. Do you know if there are any other wake up lights on the market with those features?
Hi Steff,
There is one by PURE called the PURE Twilight Wake up light that has DAB. I’m not sure where you are located, but this one is designed to work in the UK – Here is a link
Dawn simulator alarm clocks really do work, I have been using this model for over 2 years now and it makes a huge difference to my mornings, unless I’m hung over 😉
I guess that’s ok as long as you don’t have a drink problem 😉
