Fully portable and offering the full 10,000 lux of brightness the Lightphoria 10 000 Lux Energy Light Lamp is also modestly priced and has a timer and adjustable light intensities.
The HappyLight Compact Energy Lamp is one of the cheaper SAD lights on the market, but is made by the reliable chaps (and chapesses) at Verilux. It only provides 2,500 lux of light, but is compact and portable and the light tone is lovely.
The Nature Bright Sun Bliss is small and portable and pretty cheap. It is also a two in one Sunrise Alarm Clock and SAD Light, but does it meet the mark on both of these functions?
A SAD Light you wear! The ultimate in portability. This means you can get your light therapy on the move.
The Northern Light Technology Travelite puts out a lovely warm light, but it is quite pricey. What else do you get for your money?
