Definitely. Although I don't support empirical and old-fashion units.

The temperature at which objects begin to radiate visible light, the Draper point, is around 900-1000°F. That's the same temperature as regular old fire. Most high-temperature burners reach temperatures of 3000-5000°F.

The temperature of lightning is roughly 50,000°F.
