I like my off white walls and white ceiling. I do longarm quilting and need all the light I can get. I can sew at my sewing machine without my Ott light. We have 4 (4 bulb) natural color fluorescent lights on the ceiling over the 14' longarm and 2 (4 bulb) similar lights over my sewing machine. I have only one large window and 2 small ones in my basement sanctuary.
