What units do people use wherever your mother is from? ergs per second?
Wife is from China, I'm guessing maybe they do use 'watts' and lumens, it's just she was last living in China 10 years ago, presumably before more energy efficient bulbs were widely available, thus it was pretty simple to not compare watt usage to brightness as all incandescents were basically the same (more power/watts=brighter). Translating from different languages and familiarity with possible labelling and packaging differences between the two countries, etc. I know a decade or two ago I never looked at lumens, just the wattage (low watts if I don't need much light, more wattage if I need more light).
