Try SAD at 64 North. No picnic. I'd really like to try s light but don't think I'd have the patience to sit in front of one long enough. If it could be made bright enough that you could have it overhead and work at the same time that would be brilliant.

I live at 60°N. Several colleagues at work simply keep a bright-light lamp on their desk, in the general direction of the window.

I don't have SAD (well, I don't notice any particular symptoms anyway). One can imagine that luminaires pointing at a light matt surface ceiling would produce an effect like cloudy daylight, but that might just be cosmetic - the science needs to be done I suppose.

I have one of these on my desk, right next to the monitor. Working in front of it for 30-60 minutes a day really helps. Live at 60.5 degrees north. Also take vitamin suppliments and exercise more in winter; it's hard to tell what causes the improvement. With a lamp like this, you don't have to do anything outside of your routine to get more light. You can keep it 20 centimeters (~1 foot) from your eyes, so reduced irradiance due to distance (as this article points out) is not a problem.
