Here is a old fluorescent fixture.(2)
Unknown manufacturer and date.
May be a LG member can identify it.
I don't think they are Fleu-o-lier because there are no vents in the top cover.
Fleur-o-lier always made a big deal about the vents in their fixtures as the ballasts ran cooler than the fixtures without them.

May be these are RLM, but not sure.
Also one reflector has a bend on one edge at the middle.
The reflector must be paint as if it was porcelain, it would have a big chunk missing from the surface of the reflector.
Some fixtures had the option of white paint or white porcelain for the reflector.
The white paint was a little cheaper.
During the war, RLM reflectors were even made of Masonite painted white to save steel.  

But what ever they are, they are old as they have the bulb holders mounted to the reflector like the early Fleur-o-liers did.
The later fluorescent fixtures had the ballasts and bulb holders mounted to the top cover so the reflector could be removed for cleaning without disturbing the wiring.
GE contracted with Bryant to design and manufacture the very first fluorescent bulb holders.
Bryant only made bulb holders in black at that time.

Also the white bulb holders used in this fixture, if original could be made by Plascon, a bulb holder manufacturer that made fluorescent bulb holders during the war.
These were cast from the new plastic Urea, which was much cheaper and more easy to cast than Bakelite.


Early on GE had agreements to sell ballasts and Bryant to sell bulb holders and starters to only two fixture manufactures, RLM and Fleur-o-lier.
These companies had a lock on the fluorescent fixture market for a short while before other companies got into the fluorescent lighting business.
Bryant made the bulb holders and starters, GE made the ballasts and bulbs.

The bulbs made by GE and several other bulb manufactures were sold under the Mazda brand as Mazda had a lock on incandescent bulb sales/distribution nation wide for quite a while before the introduction of fluorescent lighting in the Summer of 1938.
The Mazda light bulb cartel started to fall apart when Sylvania said they were going to go it alone with bulb sales and not rely on Mazda to market bulbs.

The whole story of the Mazda group of companies and their cozy relationship with the electric utilities to create a supply and demand situation that benefited both the utilities and the bulb manufactures is very interesting.
But then the introduction of the more efficient fluorescent lighting threw the electric utilities in to a panic and warnings of dire consequences for both the bulb manufactures and utilities were made.
The electric utilities even went so far as to have fluorescent bulb manufactures sign agreements that they would not advertise that any energy savings could be gained by using fluorescent lighting.

It was the electric utilities that early on promoted the use of higher output fluorescent lighting on the theory that the higher output bulbs would consume more power than the smaller bulbs would.
The low power factor of the early fluorescent ballasts and the problems it caused the power companies only added to the confusion.
During 1942 the U.S. government investigated ten companies relating to allegations of fluorescent bulb price fixing and manipulating the distribution of fluorescent bulbs so as to divide up the fluorescent bulb sales between companies.  
GE and Westinghouse were included in the ten companies investigated.

A interesting story of fear and greed for sure.
 
  
At one time there were 30 different manufactures making the Fleur-o-lier fluorescent fixtures.
However the Fleur-o-lier fixtures were actually designed by Mazda which was a group of bulb manufacturing companies that GE and Westinghouse was involved in.
Naturally, only ballasts bulbs meeting GE and Westinghouse standards were written into the Fleur-o-lier fixture specifications to be eligible for fixture certification.
  
The Fleur-o-lier certified fixture agreements with manufactures finally fell apart when manufactures started making their own fluorescent fixtures from their own designs and did not have to pay Fleur-o-lier the fee to manufacturer the Fleur-o-lier designs.

Both Mazda and Fleur-o-lier hit the scrap heap of history.
Neither company were manufactures.
Mazda was a group of companies.
Fleur-o-lier was a association.  

  
At least the seller is willing to ship.
Also the start bid price is realistic.

A interesting unusual old fluorescent bulb display.
I don't think I have ever seen a bulb etch with a gear before.

Nice little fixture.

A round ballast circle line.

I like these (modern) chrome fixtures, but prefer the older ones with the cast pot metal ends.
I like the simple understated aspect to them.

Like this.

I hope this one finds a good home.

I have one just like these that I restored and it looks really nice.
They are the early conversion models with the pot metal ends.
These fit a 4 inch incandescent fixture.

Any vintage lighting collector in Pennsylvania could have a lot of preheaters right now, between these and the 30 or so from the Ford plant.

If somebody managed to get the entire Lighting Gallery community into one room at the same time and said "old fluorescent fixture," about 700 heads would turn at the same time. Like meerkats.
