Modern houses do have a lot more lightbulbs if you feel like keeping count, I saw a kitchen with something like 6 or 7 of them recently. Although I'd assume the big uptick would be industrial consumers. Particularly 24/7 operations with lots of opportunities for lighting. Or people would start installing better streetlamps as the ability to do so improved. But the point I'd like to make is that your lack of imagination isn't going to overcome the laws of economics no matter how much you can't imagine change. "I can't imagine basic results playing out" isn't an argument for why they won't, it just means you don't understand the situation well. Jevons' paradox flows pretty directly from the laws of supply and demand and the observation that energy demand is highly elastic because it does anything and everything. And an important concept that you may be unaware of is 'fungibility' - that means some goods (energy being a prime example) can be repurposed across a wide range of activities and not just lighting. So if people don't need to put as much energy into lighting then they take the energy they would have used and put it to something else, like more comforts in their life. It is a very reliable trend.
