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.

This Verilux HappyLight offers a variety of light intensities up to a maximum of 7,500 lux and is small and weighs next to nothing. It is also made by Verilux who have a strong brand name when it comes to SAD lights.

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?

Philips are reknown for producing high quality products that work. The Philips goLITE BLU produces blue light to combat SAD and has an adjustable timer and brightness setting

This is somewhat of a novelty - a floor standing SAD Light. It is expensive but what do you get for the cost?

A huge array of customisable features, a lovely sunrise and a battery back-up, but the Lumie also comes with quite a hefty price tag. Read my review to find out more.

A SAD Light you wear! The ultimate in portability. This means you can get your light therapy on the move.

Verilux have an excellent reputation in the world of light therapy, but how does the HappyLight Liberty 10,000 fare? You get a really variety of light and it is easy to use and move around.

Carex have made some great SAD Lights - the Sunlite offers a large area of light and is easy to move around, but does it have any other redeeming features?

The Verilux Happylight Personal is very inexpensive indeed and it comes from a reputable brand name. It provides 5,000 lux and is small and well made.
