When my sewing room was redone last year, we changed the light fixture in the ceiling. My Long Arm quilter friend found a rectangular ceiling fixture with four neon daylight tubes inside at Home Depot, and after she had it installed her quilting room was exceptionally bright with no glare at all.
I went to Home Depot, and they also sell a round one that is about 20" across, and has two neon daylight tubes inside, incredible the difference it made over my sewing table. I took a picture without the cover on it, and had to turn it off - it is that bright. It is just like sewing outside in the sunshine. It only cost approx. $75, but in the US is probably much cheaper. Another bonus is if I'm feeling tired during the day, I just have to walk into that room and turn on the light - makes me feel wide awake again.
