There are currently no-plug-and-play LED replacement options for oven lamps.

They use standard A15 style bases, but the LED A15 lamps (ergo, replacements) are always sold with plastic bases. Metal bases are required for oven lamps, but metal base a15 luminaires are always incandescent. Why? LEDs are temperature sensitive, and the mounting brackets are made with plastic, which is also thermosensitive. Although residential scale replacements aren't in demand, commercial scale operations that utilize oven lamps may find themselves interested in such a product in the future – perhaps the near future. This is another practical barrier to 100% LED lighting, albeit a minor consideration but a reality in the field.
