The goLITE BLU is a serious and very useful mostly conventional light therapy device which helped me go from 7 to 8 hours of sleep, although recently I've found an even more conventional type like this makes an even bigger difference, enough to maybe get off a drug I've been taking for a decade (weasel word "maybe" because I'm off it but still seeing if I can get back to a regular 8 hours): http://www.amazon.com/Carex-Health-Brands-Day-Light-DL2000/d...
The grandparents post is an alarm clock. The blue light things you use during early morning like with breakfast to prevent SAD. I found the alarm clock to be amazing for about a week and then not much different than other alarms after I adjusted to it. That said I still prefer it to other alarms.
