We have two, both used by my husband (normally a night-owl) to get his sleep-waking cycle on track. After getting his eyes checked for any abnormalities, his doctor prescribed the lightbox treatment.
The lightbox that had the nicest, warmest glow in our experience has been the Sunbox "Sunray" model. My husband used to check his email first thing in the morning, with the lightbox shining ~12 inches behind his laptop so it wasn't directly dazzling right into his eyes. It sure did beat the cheap, clinical, and glaring fluorescent lighting that was in our kitchen. He'd leave it on while I was preparing coffee and breakfast, and switch it off after we were done with breakfast. It was such a nice light, even though I sat with the back of the lamp facing me (so I didn't get the light directly) and I didn't think much of the aesthetics of the lamp design. I grew to appreciate the Sunbox more and more. Breakfasts, even in the dead of New England winter, were cheery. Our coffee looked better, my cooking looked better, even my husband's complexion looked rosier with the Sunbox on.
Whenever he switched off the lamp, my mood dimmed a little. I blame my own (slight) mood change on -- not on withdrawal symptoms -- but on the sudden visual reminder that our kitchen lighting was awful and my husband wasn't the rosy-cheeked person the Sunbox made him appear to be :-)
