Replacing a light bulb
 
I have been having a huge amount of trouble identifying a halogen blown halogen light bulb I need to replace in our oven. I have looked at the bulb, the fixture, the lens, the heat shield, the manual, called the manufacturer, looked at the oven parts list, contacted a third-party parts website and ultimately I believe I know the specs for the bulb, but I feel I need to know the risks of getting it wrong.

I believe the bulb is a 120V, 20W, G5.3 Bi-pin - something similar to this. Note that the image is of a G8 not a G5.3!

I'm not asking for help finding the bulb for sale (although if I can confirm the specs then that would information would be really useful!). Instead I'd like to know:
- What would happen if I put a 120V bulb in a 12V fixture?
- What would happen if I put a 12V bulb in a 120V fixture?
- Can a bulb be rated for external temperature as well as fixture type, voltage and wattage?

120 volt lamp in 12 volt fixture will not light

12 volt lamp in 120 volt fixture will blow out in a second.

Temperature rating should not be an issue.

Perfect answer! Thank you very much - I'm going to hunt down a 120V bulb and test it out.
