> In the early 70's. There were less lights in poor homes. The more affluent homes had suspended lights with multiple bulbs. (I am not sure how it is called in English). I recall that a lot of homes got more light bulbs and ornaments through the century, as they become more affordable and more hype. The increase in count came with a decrease in power. The typical 100-150W bulb got replaced by multiple 30-50W bulbs, they do not consume significantly more in aggregate.
