This one is in the center of the kitchen. Reminds me of a spaceship. The house was built in 1958, so I believe the lamp was made around that time.
The pull-down lamp in the corner has the same perforated cone as the fixed lamp in the first photo.
One of these days I plan to take these lights down for a cleaning, and hopefully there's a manufacturer's label on the inside. I'd love to know what company made these.
