LED Light Bar Arch

Ever see something while cruising the internet and wish you had made a note of it? This last week I saw a great idea of a curved arch of LED light with the idea of adding light to a dark work area. My southern exposure at my modeling table gives me a light of light. However on foggy days it's a bit gloomy. Some one made a arch with LED lights on it. Each end was mounted to a block of wood with weights added (I think) and it was about three feet of separation at the base with a curve of these LED lights. Has anyone else seen this? If it doesn't cost too much I could really use it on dark days. I wish I had looked closer at it. Hell of a idea. Thanks for any help you can offer. wc
