I like my sewing room really bright. I describe it as "noon at the equator". LED bulbs are wonderful because you can buy a lightbulb that is 19 watts so it will fit in a 60wt fixture, but it actually gives off the equivalent brightness of a 120wt incandescent bulb.
I have a lamp with 3 bulbs in it that are all 19wt LED's. It's fantastically bright. I can see the colors of my fabric clearly & can see well enough to sew tiny needle turn stitches no problem. I have 2 other lamps in the room because there are no lights in the ceiling.
