Litebook Edge SAD Light

Availability Notice:

Litebook Company Ltd. has discontinued the manufacturing, distribution and sale of consumer and/or research light therapy devices for a period of one year. The company will be focusing their resources and efforts on the design and development of new products, as well as maximizing the benefits associated with their patent portfolio.

Current ETA for new stock: Late Fall 2020

The Litebook Edge SAD Light emits light that is the equivalent to 10,000 lux at 20 to 24 inches. Research demonstrates that the effectiveness of light therapy is less dependent on the intensity (LUX) than on the wavelength of the light. The key wavelengths in fact match the peak wavelengths of sunlight, and are called the ‘action spectrum’ for light therapy. Most users find that they need less time (15-30 minutes/day) with Litebook products than they did with larger, 10,000 LUX units.

How to Use a SAD Light

  • Typical usage time is 15-30 minutes a day. Regular daily usage is recommended.
  • Optimally, The Litebook Edge should be used first thing in the morning, as early as possible upon awakening.
  • For some people, especially seniors, who fall asleep earlier than they’d like and wake up either too often or too early, we recommend using your Litebook Edge in the early evening to tell your body that you’re not ready to go to sleep. This will help you sleep through the night and awaken at your preferred time.
  • The Litebook Edge SAD light should be positioned approximately 20-24 inches from your face, and should be offset slightly from centre to reduce glare (see diagram).
  • Can be used on either left or right side, results will be the same.
  • The Litebook Edge’s light beam must be directed at your eyes, and your eyes must be open to achieve benefit.
  • Typically, you will recognize when you've received sufficient light - most often by feeling of heightened alertness, energy, and/or mood.
