What I purchased is a LED lighting strip that attaches to the machine itself and shines down onto the sewing plate and needle area. It has a USB that plugs into a conventional plug that uses standard US alternating current. For me it eliminates the shadows that were thrown by my previous sewing lamp, making it so much easier for me to see what I am sewing. I don't know how to post a pix. A link is the best I can do
