request for advice about lightboxes

[baratron]

After a couple of months of feeling blah which hasn't improved, I recognise that the dawn simulator alarm clock I have just isn't enough to deal with my SAD this year. Lying in bed with the full light of it streaming into my eyes barely improves my functionality. I feel like I'm living in perpetual twilight, and have very little inclination to do anything.

But I have a problem with buying a lightbox. I'm very environmentally conscious. Every room in this house, bar the kitchen, is lit with low energy fluorescent bulbs because I want to consume as little electricity as possible. I really don't want to use a lightbox that's running at 200 W for an hour a day, because that's like leaving every light in the house on for an hour a day. And I'm having great trouble finding out the energy consumption of different lightboxes from seller's websites. Some of them mention a 55 W fluorescent tube, or 2 x 80 W bulbs, but others simply say things like "LED lights consume only 1/10 the power of conventional incandescent lights, yet are 10 times brighter". Great, wonderful, white LEDs are lower energy than ordinary lightbulbs - but are they lower energy than a fluorescent tube? And more to the point, are they as good for SAD?

So, uh, if anyone knows someone I can talk to about this, or a retailer that details the energy consumption of every lightbox so I can make a fair comparison, that'd be great. (I simply don't have the energy to visit individual manufacturer's websites to try to take in information :/ )

This page suggests that tubes are 2 to 3 times as efficient as incandescent lights and LEDs are tending towards 10 times as efficient.

it is a bit vague, and doesnt mention low energy light bulbs which I dont think are the same as full sized tubes.
