I picked up a neat little one the other day at Joanne's. It is cordless, takes 3 AAA batteries. I don't need it all the time, my machine is in font of a window. Great during daylight, but I needed something more at night, or dark days. This can be free standing, but I have it adhered to the side of my machine. The flexible arm is about 12 inches and has 3 little LED bulbs in it, so it doesn't radiate a lot of heat. $15.95, but I had my coupon. It suits my purpose.
