***High Temp Lighting***


Hello all,
I built a brick oven over 6 months ago,, It works great.. An afterthought I had was to put a light inside.. Are there any kind of Industrial fixtures that would withstand heat (in the actual oven of 100000-12 degrees) (in the enrance archway about 3-500 degrees) not much room in the archway though... Im sure there would have to be some high temp wiring as well... Open to suggestions....

Thanks
Mark

Well a kitchen range oven would use a porcelain socket and special high temperature rated wiring. You could pull this from an old range or order the socket part from an appliance store.

And they have this designed so just the bulb is sticking out into the oven, the socket and wiring being in the compartment behind the oven (cooler back there).

The high temperature range wire is available only at appliance stores in my area. I don't know what the ratings are for this wire, but I suppose you could find some of this wire and see what is says on the package or contact the manufacturer.

I was not clear on the temperatures you listed above? Did you mean 100,000 degrees F.? I should think that would melt the metal in ANY wiring?

Melting points of various metals...

Self cleaning ovens may reach 900F but the light is out during this process.

"The invention relates to an electric lamp including an envelope of quartz glass or a similar high melting-point material . . .
in which at least one strip consisting of a metal foil. . .
The foil consists of a metal having a melting point of more than 1,500C so that during sealing in the foil cannot melt. For this use a metal is chosen having a low thermal coefficient of expansion. Usually the foil consists of tungsten, molybdenum or a suitable alloy of tungsten and molybdenum. "
