Industrial units using rare Type RF fluorescent lamps

Industrial units using rare Type RF fluorescent lamps

The Type RF fluorescent lamp was an unusual lamp with 2 prongs on one end and three on the other. Likely obsolete by the late 40s and I bet they are quite rare now.

Must have been a weird wiring.. Were those F40T12 preheat? Or was it an older gear system?

Man, we're whining because we're short on preheat tulamp ballasts but think about finding one of those extreme rarities. Probably 2 or 3 left in the US

Also, the ballast on top look awfully oversized.. Since it's a 3-prong, do you think it might have been one of those long and huge types with one per lamp? Or it's just the enclosure that's oversized..

How did it work? I've never heard of that.

Nothing like the beautiful cool white light of a coated Mercury Vapor lamp and the soothing hum of it's magnetic ballast.

The Type RF lamp was a 5' long T-10 lamp. They were self rectifying which means they rectified only in one direction. One end has two filaments, the other end has one (anode and cathode, can't remember which end are anode/cathode). The auxilaries were indeed large with many parts inside. They only came in two colors, industrial white and blue white.

May all the great lighting technologies have their place in history.

I would LOVE to have one of those fixtures!!! WOW! It looks similar to the industrial units I have from the old mills and warehouses. Are there any pictures around of the lamps and gear?

Preheat Fluorescents forever!
I love diesel engines, rural/farm life and vintage lighting!

Yes there are pics, in a couple of days or so I will post pics of one fixture showing details of a lamp and a diagram of the ballast that operates them.
