The HappyLight® Lucent LED and HappyLight® Touch LED Light Therapy Lamps are portable and pack flat. The Lucent is the size of an e-reader, and the Touch is the size of a tablet. Both are durable and fully portable.
The HappyLight® Liberty Compact Light Therapy Lamp is small, box-shaped, and can be put in a large purse or gym bag. However, it does have a CFL bulb inside so it should be handled with care.
