SAD Lamps: Our Verdict on the Biggest-Selling Models

Find out how the bestselling SAD lamps and SAD lights fared when we tried them out.

SAD lamps are one type of treatment for the winter blues or more-severe winter depression, seasonal affective disorder. Some users find that they can be effective but you need to choose carefully when picking a lamp as the range on offer can vary dramatically.

We've come across models that recommend you only need to use them for 20 minutes at a time, while others require sessions lasting for two hours - hardly convenient if you have a busy lifestyle.

And you need to take some of the products' marketing claims with a pinch of salt too. After all, would you describe a lamp weighing 4.2kg as being superb for people on the go? Or a lamp that's 38cm tall as compact?

Which? user trial

To get a better understanding of what popular SAD lamps have to offer we asked two people, one of whom regularly uses a SAD lamp, to try each one out and to tell us what they're really like to use. 

We couldn't ask our triallists to tell us whether these medical devices are proven to work, but we've reviewed the research evidence. See our SAD lamps buying guide to find out more about this and to learn how they differ from sunrise alarm clocks.
