I have my sewing machine against the wall between two windows, then on the wall I attached a 30-inch fluorescent light. In the daytime I open up the blinds and there is plenty of natural light, and then I turn the wall light on at night and on cloudy days. My Janome Horizon has sufficient lights that allows me to sew without hurting my eyes. When I am doing dark fabrics, then I put an Ott light next to the machine. Sometimes I use one of those LED head gear that plumbers and carpenters use which I focus on the needle part.
