I actually like the compatible watts for light bulbs. They should absolutely also prominently list a correct measurement (I assume linens?), but I only know how bright it is based on the old watt comparison.
Just like crop frame cameras list lens lengths in full frame equivalent because that is what people understand. But they also need to lose the actual mm.
The problem with these types of mandates is it locks us into standards and makes change hard. Imagine if they had done this when the terrible USB port was dominant.
Or, it gives all the power to the USB group. They have a terrible track record (USB-C is a mess).
The other problem is all the cheap devices that have a USB-C port, but will not charge from a real USB-C to USB-C cable. They are the same old USB ports electrically with a new shape.
These are bad laws with good intents.
We taught our daughter to count starting at zero. Her kindergarten teacher was not amused.
