Feeling SAD (and poor)? Make your own light box for cheap

I love fall, but winter makes me a little sad. In fact, it makes me SAD: like millions of others, I experience seasonal affected disorder every year at this time due to the lack of sunlight.


One of the things that can help SAD sufferers is a light box which emits a very strong light (more than 10,000 Lumens, whatever they are) but such boxes can be very expensive.

I never thought that they were something an amateur could make at home but it turns out I was wrong. Lifehacker this week linked to instructions to make your own lightbox, as written by an Austrian blogger called Boris Le Gradic. This would cost a fraction of the cost of buying one retail, and emits a whopping 16,000 Lumens (again, whatever they are) so there’s no excuse for not shining a little light onto your problem.

Unless you’re really bad with a drill, I guess.

PS: Okay, I looked it up, and Wikipedia tells us that:

The lumen (symbol: lm) is the SI unit of luminous flux, a measure of the perceived power of light. Luminous flux differs from radiant flux, the measure of the total power of light emitted, in that luminous flux is adjusted to reflect the varying sensitivity of the human eye to different wavelengths of light. The lumen is defined in relation to the candela by

1 lm = 1 cd·sr = 1 lx·m2

I hope that clears up any confusion.
