Comment on lightbulbs
ChaoticNeutralCzech@feddit.org 10 hours ago“You want cold white or warm white?”
“I need a cold light source, like an LED. I’m afraid the fixture would melt if I put incandescent in there.” (Yes, some E14 fixtures in cheap plastic bathroom mirrors etc. only take up to 10-20 W and have a warning sticker)
“What, higher temperature is colder?” (It’s not their fault though that in nature, white and blue things 🧊 are generally colder than yellow and orange things 🔥)

It does not help that some people pronounce LED as “led”, or “ice” in Slavic languages. And “led lampa” is a homonym of “letlampa” (bunsen torch).

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.

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).
