Starting April 1 Langara Library will have two Light Therapy Lamps (also called SAD Lamps) available for one-hour loan for use in the library only. You can ask to sign out a lamp at the Library’s checkout desk.

What is it?

Light therapy lamps mimic spring and summer light levels as a mode of treatment for Seasonal Affective Disorder (SAD), adjusting to a nighttime work schedule, jet lag, and the general feeling of the winter blues – low energy, irregular sleep patterns, and irritability.

How do I use it?

Find a tabletop workstation near an outlet, plug in the lamp and turn it on.

Sit facing the lamp, about 1 foot or 30 centimeters away, for 20-30 minutes while you are reading or studying. Your eyes should be approximately at the centre of the lamp but it is not necessary or recommended to look directly into the light.

When you are finished using it, turn the lamp off, unplug it, and return the lamp to the checkout desk.


Light therapy is considered to be safe for 20-30 minutes of use, and is most effective in the morning. Side effects are rare and if they occur they are usually mild and can include nausea, headaches, and/or eyestrain. There are no known long-term side effects to light therapy. If you experience discomfort, stop using the lamp. Consultation with a physician is recommended before undertaking a bright light therapy regime, especially if you have a mood disorder, are on prescription medications, or have a history of eye conditions. Use of the lamps is at your own discretion. Langara College is not liable for any health issues related to use of the lamp.

A full list of precautions and directions for use is available upon request from the library checkout desk.

Light therapy is one form of treatment for SAD, other mood disorders, and the winter blues; it is not a cure.
