This is a vintage Nalco incandescent heat lamp. I have no idea as to its vintage. Does anyone know around when this bulb might have been manufactured?

Very cool, I have one like this too. Definitely carbon filament.

Say NO to bulb bans! The bulb ban IS inline with the principles of communism. Yes, exactly.

Carbon filament lamps for heating are still manufactured, since they are very efficient in producting infrared radiation.
I saw in the past, in the storage of Carmel hospital, a portable heating fixture (That operates from the mains supply, and operates as soon as the plug is connected to the outlet) with a heating carbon filament lamp with a shape of the modern european 60W classic shape incandescent lamp.
The lamp had a wood glass (The color of the glass was the same to wood glass), to filter the visible light and let only the IR radiation to escape.
I operated this fixture and so i could be able to realise that the filament is a carbon filament.
The fixture and the lamp were for medical purposes in the hospital.
However heating carbon filament lamps are non exists in commercial IR lighting in Israel, and instead lamps with tungsten filament are used usually.
This is probably because carbon filament lamps can't be shaped into directional and PAR shapes because of the size of the carbon filament, and most of the commercial applications in Israel, uses directional IR lamps.
This may be the case also in the US and another countries.
So for medical IR purpose, where the directional radiation isn't required, carbon incandescent lamps are used.

I"m don't speak english well, and rely on online translating to write in this site.
Please forgive me if my choice of my words looks like offensive, while that isn't my intention.
