dont really know but my good friend that saved these said there holophane atleast he believes they are age well he's just guessing 1949 ? it's up to my friends on here to help find info im at a lost iv'e never seen anything like this before
I worked on a few of these over the years. The ones we had were put up in 1966 and attached to county buildings. Ours were incandescent and I converted them to CFLs. Back then we didn't have good screw in conversions so I had to mount a ballast behind the fixtures and used a 20 watt U-tube CFL with the 4-pin base. Given that the incandescent bulbs were overkill the 20 watt CFLs worked fine. Great score!
