Light Therapy Alarm Clocks

Waking up to a loud alarm clock is hard on even the lightest sleepers. Not only do they startle a person awake, but they often give an unfriendly welcome to the new day.

Now, there is the option of wake-up lights, which are therapeutic and relaxing, but still wake a person from a deep sleep.

While numerous models are flooding the market today, there are three lights that get the job done and avoid the grumpiness of the morning: the Philips HF3520, Philips HF3606, and Totobay.


Totobay offers a sunrise-like awakening. The wake-up light gently increases to help a person transition from a deep sleep to a wakeful state. It gradually moves from 10% light up to 100% light—just as the sun would as it rises.

It also offers a sunrise feature to help a person naturally fall asleep, decreasing light intensity from 100% to zero in a 30-minute window.

  • Comes with ten separate light intensities.
  • Includes gradually increasing natural sounds for a traditional wake-up.
  • Can program to an FM radio station.
  • Snooze button gives nine minutes of sleep before re-starting.

Philips HF3520

Light Therapy Alarm ClocksThe Philips HF3520 came before the HF3606, but still includes excellent features and is more budget-friendly than the HF3606 version—averaging just over $80.

What is Great About the Philips HF3520?

  • Colored sunrise simulation that is better than others on the market.
  • 20 different brightness settings.
  • Increases light intensity from 20 to 30-minute programs.
  • No replacement bulb needed for the entire lifetime of the unit.
  • Traditional alarm features also included.
  • Non-slip rubber feet for easier placement.

  • Not as many sound features or sunset features.

Which is the Better Wake-Up Light Alarm?

All three alarms offer a better wake-up experience than the traditional noise-based alarm. While a person could include noises, all three can be used with the light alone and have multiple options.

For those who want maximum color choices, the HF3520 has 20 brightness settings. However, the Totobay is the only version to offer a sunset and sunrise feature for the better waking and sleeping cycles.

All three are relatively expensive compared to traditional alarms, but the most affordable is the Totobay.
