Help Identify Diffuser Lenses from c 1949 recessed Fluorescent Fixture « on: February 02, 2026, 06:53:22 PM » Author: 1949 Chapel
I've got some diffuser lenses from some recessed fluorescent fixtures in a building built in 1949.  These fixtures were set in a hard plaster ceiling.  I'd like to know a probable manufacturer.  Anyone have an idea who might have produced these?  Photos attached.

These might be made by Holophane. I believe they produced a lot of the glass for early fluorescent fixtures.
