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.

May I ask what size tube they use?

I like math, lighting, computers and electronics(but I detest fractions and pointless ruinage of lovely old stuff). LEDs should be better thought out. they are actually quite good if they are good quality. They should be built to a long actual life not to a cheap price!

There were four diffusers per fixture so I assume normal 48" tubes.  I think there were two or three tubes in each fixture.  Don't remember exactly.

If you have any of the original fluorescent fixtures, some collectors on here might want some as they are getting pretty rare.
