    Do people actually confuse color temperature with operating temperature? I wouldn’t want any lights in my house if their operating temperature was ≥2700 K. I want the room to be bright, but not if that means melting the steel beams in the ceiling.

      The colour temperature of an incandescent lamp is, exactly and by definition, its operating temperature.

      A 2700K lightbulb will not melt steel. The glass is not that hot (you can tell because it’s not glowing itself). In any case, it’s really power that matters - a small object at 2700K will not damage steel if it’s not being continuously heated; it needs to be heated at a rate which brings the steel above its melting point before the heat can dissipate.

        Yes, for incandescent lights that’s true. Are they still being sold?

          Probably in some places, but that’s not my point. People remember that lightbulbs are hot, and it’s literally called colour temperature (for good reason).
