If this is an industrial oven....like a pizza oven then a small metal halide
lamp can be used...I have seen this in a local rotery pizza oven

MH lamps dont mind the heat and can last a L O N G time

wattages are available down to 39 watts (who comes up with these offbeat
numbers) and the 50 watt type fits a medium screw based socket .

If this is a home oven check on flea-bay and stock up a dozen bulbs this
should last like 10-15 years with casual use.

Does anyone make an LED or similar type of bulb for high temperature
applications like oven lights?
