I bought mine from Clotilde and then gave both of my DD each 1.They really help.I usually use them at retreats and classes due to the light not being good.At home I use the clip-on Ott light.
I have a bendable sewing light that attaches to my machine. I couldn't sew without it and it throws a nice bright light on my needle. I bought it on line at Quilters Warehouse.
