Light source: Get a light that emits frequencies mimicing sunlight as closely as possible. Make sure it's easy to use under a range of circumstances. If too large, heavy or awkward then a tendency to not use it defeats its purpose. Some run on rechargeable batteries and are quite portable and easy to use. Led lights work well even though they are not totally sunlight similar.

10.000 LUX: The key will be a light box that is 10, 000 lux to be effective. Look on line and there are multiple companies that sell this. Also use properly in the morning for a max of 30 minutes.

Multiple uses: Light therapies can be used for treatment of seasonal affective disorder (sad), a kind of depression that occurs at a certain time of the year, usually in the winter. Also, light therapy or phototherapy (or heliotherapy) consists of exposure to daylight or to specific wavelengths of light using lasers, light-emitting diodes, fluorescent lamps, or dichroic lamps to treat various skin conditions.
