You were deductive, cool. I was in an more empiricist household. So we shove the smallest cousin into the fridge and locked the door, then we ask him to recount his experience. He confirmed that phenomenologically speaking, the light does indeed appears to go out when you shut the door.
(am gonna use European standards here sorry Ameribruvs.)
Also, 200w bulbs that fit into fridge socket? The "40w max" is usually in normal E27 sockets. (The regular light bulb socket.) And the largest lamps for those I've seen are around 50-80w, and pretty much always sold as "growlamps".
Going to 200w you'd need an E40 socket. They're about twice the size of the "regular" E27 (and E14 is the smaller "candle" socket, that's like half the diameter of the regular one). Here's what a 200w bulb looks like and remember that the socket is twice the size of a regular one. That bulb is like ~40cm long.
Idk what socket fridges use though, but I seriously doubt it's anything close to an E40 size.
If we're talking just at home, I'd have to disagree. But yeah I think probably fairly commonplace for industrial use maybe?
I don't recall ever seeing a single one being sold back when I used to be sent out for lightbulbs, because incandescents popping so often were a designed feature and as a kid I wasn't going into proper hardware stores.
40w and peeeerhaps 60w would be the most common ones, I'd say. Might vary ofc depending on where and who and when. But for like general house use in Finland I'd say those were definitely the most common ones. I'm guessing that's sort of why lamps have the "most 40w" so that people use at most the 40w incandescent if someone still has those? Because newer ones draw so much less, there's no need to design the schematics so that it can take 120w when most LED bulbs range from 7-15.
I'm talking 40% of my arse so please do correct me for the mistakes I think I must have made
Buuut the European grid runs at 230V, while the American grid runs at 120V (240V enters the home with a +120V and a -120V rail, and most circuits are attached across one of those and a neutral, except for high power appliance circuits).
So our 100W bulbs are the equivalent of 50W European bulbs.
Yeah ours is 230v and high power connections like stoves can utilise up to 480v I believe.
My sauna uses 400v for example.
Lumens are simpler when it comes to lighting, yeah. No more "equivalent to X watts" bullshit from marketing people if the general public understood lumens.
Alas my apartment building is from the 70s. Also Norway isn't as enlightened as Finland. I would also like a steady supply of that hard round rye bread with the caraway seeds, but I don't have a car and I'm not taking the bus to kilpisjärvi for bread.
If it's really a 200 watt bulb, which I doubt, it won't actually pull 200 watts, that's just what it would pull if it was available but I doubt the fridge will pass that through. It would be a pretty stupid design otherwise.
