But consumers don't really like this pseudo-white light of LEDs
Actually, we know four things about demand for LED light. Here's your two to start:
"We really only know two things about the demand for light. (1) Historically, when the price falls, we just use more of it. (2) Secondly, at some point, we expect satiation and thus increasing efficiency to lead to reduced energy consumption."
But there are four, not two, characteristics that contribute to the demand for artificial light: (1) price (of purchase and/or operation - you choose), (2) supply (availability), (3) quantity of light produced by a device (lumens), and (4) quality of light produced by a device (spectral emission of light).
Business/industry and government may be focused on the cost of energy consumed, the cost of the bulb in the first place, and the brightness of light produced, but the consumer has a larger concern: the quality of light produced by blue LEDs. The quality of light produced by LEDs is most often described as flat, harsh, eerie and unattractive. Until blue LEDs produce white light - real white light with a full spectrum of color emissions - public demand will be dampened. Nobody wants to sit down in their living room in the evening and look like an alien being in the greenish-yellow "warm" light of an LED "white light" bulb. It doesn't matter how much energy they could save...
