It stimulates the conditions of sunrise to wake the user up in the most natural way possible using light therapy and 5 different natural sounds, leaving the user refreshed, instead of confused and disoriented like other abrupt alarms sounds.

The Philips HF3520 dawn simulator alarm clock is a wake up light featuring colour changing LED lights that replicate the changing tones of the sunrise.
- Gadget Viper
This alarm has the most soothing simulated sunrise and sunset, which may help you feel less groggy. It has a good range of alarm sounds, a second alarm, power backup, and a sleek design.

One of the coolest features about this particular light alarm clock is that it doubles as a bedside lamp.

The way the Philips Wake-Up Light works is simple and easy. You set up your preferred wake up time for your personalized sunrise.

Before you go to sleep you can set the light, which also works as a bedside reading lamp, to dim slowly. The LEDs inside are not replaceable but are designed to last for many years.

The clock will slowly bring light in around as the time comes to awaken, which has been proven to help with that transition by mimicking a natural circadian rhythm.

Although it’s a beautiful alarm clock, it lacks multimedia/aux/USB support (although it has an FM Radio) and is not recommended for deep-sleepers or college students.
- Top Ten Review Pro
The solid, orb-like shape of the HF3520 made it difficult to lift away from the nightstand when I was dusting. Although the rear extension makes it more stable, that also means you can’t align the clock against a wall.

An Overview On Alarm Clocks

Waking up is never easy, especially if you don’t get to do it on your own. Alarm clocks have been used for more than a century for pulling people out of a deep slumber, evolving in sophistication along the way. Many people today use a smartphone to wake up, but there are still benefits to an alarm clock. It frees you from the burden of having your smartphone next to you as you sleep, for one, while also giving you a wider range of options as to how you’ll be awoken.

If it’s been a while since you’ve gone alarm clock shopping, you may be surprised to hear about the many options now available. You can still get the standard digital alarm clock that lets you choose between disruptive beeps and other noises versus waking up to a local radio station. But there are also alarm clocks that sync to your phone, letting you wake up to music from your playlist.

There’s another option that you may have missed along the way. One alarm clock actually model uses light therapy techniques to wake you up gently and naturally. It simulates the natural light from the sunrise, working with your body’s circadian rhythms to gently nudge you awake. Even some digital clocks use changing colors as a wake-up technique to combine this new approach with traditional alarm clock design.

One thing to consider is the ease of use of your alarm clock. You’ll likely want a digital readout that you can decipher when you roll over in the middle of the night, but you also don’t want it to be so bright that it lights up your entire room. If you’ve ever struggled to set the time or change your wake-up alarm time, you likely know the importance of ease of use. It’s important to consider that feature when you’re shopping, especially if you wake up at different times every day.

The Alarm Clock Buying Guide

  • For visually challenged consumers, there are alarm clock models that not only have a display that is easy to read, but they also give you details you can use after waking up, including the day of the week and whether it’s morning, afternoon, night or evening. If you want to use the alarm clock for reminders, certain models even offers an alert that reminds you when it’s time to take your medicine. The information on the screens of these models are also clear from every angle.
  • If you’re looking for something simple and straightforward, consider the RCA Digital Alarm Clock, which is small but features the numbers prominently enough for you to make them out even in your sleepiest state.
  • Brightness preferences can vary dramatically from one person to the next. The RCA Digital Alarm Clock has a high/low brightness control that lets you find exactly the level of light you want your clock to put out. Other models also have that feature, but the minimum brightness still may put out too much light for some.
  • There’s an alarm clock for every budget.
  • Simple designs also mean easier operation. The RCA Digital Alarm Clock has easy-to-use buttons and a full-width snooze button for those mornings when you just can’t get going. The only downside to this alarm is that the minute and hour buttons go in only one direction, so you’ll often find you have to run the full cycle to get to the desired time.
  • Although it may seem complicated, setting most alarm clocks is surprisingly easy. You simply choose the wake-up time, and if included, select from one of five wake-up sounds. Some models also allow you to customize the light to the intensity that works best for you. If your model has a simulated sunrise, for example, thirty minutes before your scheduled wake-up time, the simulated sunrise would begin, reaching full intensity at the end of that time period.
  • Morning isn’t the only time your alarm clock will help you. Use models with a light as a bedside lamp to read at bedtime each night. As it gets closer to your preferred bedtime, you can dim the light slowly to gradually ease you into a peaceful night’s sleep.
  • Some clocks have a unique round design with seven different light-emitting colors that you can change at the touch of a button. In a dimly lit room, the chosen color can set a mood.
  • If you want to be able to wake up to FM radio, you’ll want a model with a strong FM reception.
  • If you want to wake up to your own music, look for a model with Bluetooth connectivity. This will allow you to stream music from your smartphone.
  • If the power dies overnight, what will happen to your alarm the following morning? With a battery backup, you’ll be covered no matter what. The RCA Digital Alarm Clock has battery backups. Many of these clocks backup for up to eight hours after a power failure. The RCA Digital Alarm Clock’s backup uses a 9-volt battery that isn’t included.
