I do have the light.
I have mixed thoughts.
My machine is in a cabinet that has no support under the machine so it bounces the light. I used tape to hold it in place.
The bulb gets warm
It helps light the area by my needle well
My Ott light does the work when I am matching patches but the little light does the work for threading my needle. Once my machine is sewing I am never looking in the area where the light is shining.
