Said to be helpful for coping with our northern, grey, gloomy winters, jetlag, insomnia, and other light/diurnal concerns. We bought this new and used it for a winter a few years ago, but haven't used it since. Maybe it's right for you? Comes in the original box with all its parts, works perfectly as new. Made by Uplift Technologies in Nova Scotia. Currently selling for around CA$200 new. I'll take the ad down when it sells so you don't have to ask if it's available.
