I use free standing pole lights. Each one has three separate lights on it that I can turn on separately and they all swivel, in that I can direct them where I want them/need them. They worked so well that I bought them for all three of my work stations.

I found with having a light on my sewing table, I tended to keep having to move it while working on my quilts, because it kept getting in the way, defeating the purpose of having it to see better with.
he Pole lights or tree lights as they are sometimes called, could be placed anywhere close enough to my work stations and sewing table so that the fabric/quilt had room to go over back of the table without changing how I could see with the light and I didn't have to keep adjusting placement of the light,because it wasn't in the way of my fabric/ quilt as I was sewing.
