Dubious. Most people would not rewire a room in their house to install a new ceiling light because a new bulb was half as bright as the old, because the new bulb would probably still be adequately bright and the new light level is something they could adjust to (much easier than rewiring their ceiling.)
In other words, there isn't a linear relationship between bulb brightness and the number of bulbs people use. The number of bulbs people use is relatively unresponsive to bulb brightness because bulbs need fixtures and changing fixtures is a pain in the ass.
- _ph_ 2y agoThere might be no connection to how many bulbs people use, but how powerful they are. If you make bulbs less efficient, people will uses higher-power bulbs. Like 100 instead of 60W. And if the dimmer bulb is good enough, why not use a 40W bulb in the first place?
- bonzini 2y agoThe problem is that nobody checked lumen/watt, or had the knowledge to make an educated choice based on it. Imagine you sold a 2000 hr bulb that has two filaments in it, in parallel. It would fit the same fixture and make the same light as the equivalent 1000 hr bulb, but it would consume more because it runs at lower current and temperature. You would make more money: almost all of the cost is the same as for the 1-filament version, but you could sell it for a higher price because it lasts twice as long. The buyer would pay for it slowly in the electricity bill, and ultimately be screwed.
