We had to move our office in an area of the house that gets very little light. Someone I know works where they make them in Montreal so they brought me one - the best gift I've received!
Helps tremendously during the long dark Canadian evenings for sure & I love the winter but would get the winter blues despite that!
Anyhow - the one I have is the SADELITE (hahahah imagine how I chuckled when I read the name!) from Northern Light Technologies - here's a link
