I have been wanting to build a industrial type desk lamp for a long time. I finally got around to it. All the tools used are US made. The sockets are Craftsman, and the wrenches are various US made. It's fully adjustable by turning the knobs made from letter stamp punches. The bulb is a 15 Watt, but any size bulb up to 60 Watt can be used. The little guy holding the spool is made from a Master Lock pad lock and a lug nut is used for his head. He is help keeping the cord in place.
This is for sale on my Etsy store. Please visit the link if your interested. https://www.etsy.com/listing/99425324/industrial-desk-lamp
