E27 100w incandescent bulbs were common in the US until the switch to LED. Looks like you can even still buy them, but at this price I’m guessing they’re new old stock that’s been hoarded to resell later: https://www.walmart.com/ip/GE-100-Watt-Basic-Light-Bulb-4-Pack-GE-41034-1710-lumen-A19/150144812
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.
I’m glad everything’s labeled in lumens now.
Not Linux!
