The Litebook® EDGE 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.

Usage Guidelines

  • 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 should be positioned approximately 20-24 inches from your face, and should be offset slightly from center 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.

Easy and convenient to use.

The Litebook® EDGE emits an intense beam of white light. DO NOT STARE DIRECTLY AT THE LIGHT SOURCE. It is NOT harmful to glance at the light for a few seconds at a time.

We encourage use of The Litebook® EDGE while engaged in other activities, such as reading, eating, applying make-up, or working at a computer or desk. However, take care that The Litebook® EDGE is NOT brought into contact with water or heat-producing appliances, as they may damage The Litebook® EDGE, and may pose possible fire hazards.

If you have a history of eye disease including, but not limited to, macular degeneration, have undergone laser corrective eye surgery in the past 30 days, or if you are currently taking any medications including certain antibiotics which render you photosensitive (extremely sensitive to light), consult with your ophthalmologist or health care provider before using product.

Consult a medical professional before using this product if you have been diagnosed with Seasonal Affective Disorder, depression, Bipolar Disorder, mood or sleep disorders or if you are taking medication for the treatment of depression and/or mood disorders (including but not limited to: fluoxetine (Prozac®), fluvoxamine (Luvox®), paroxetine (Paxil®), sertraline (Zoloft®), venlafaxine (Effexor®), nefazodone (Serzone®), Wellbutrin® and Zyban®). Light therapy may change the effect of these types of medications.

Occasionally mild side-effects may occur which usually resolve after a few days of use, including headaches or a ‘stinging’ sensation in the eyes. If these or any other adverse effects not listed do not resolve after three days, discontinue use of The Litebook® EDGE and consult your health care provider. On very rare occasions and usually only with over-use, less than 1% of users may experience mania (periods of abnormally and persistently elevated, expansive or irritated mood). If this occurs, discontinue using The Litebook® EDGE immediately.
