It is wholly a confusion to suppose that more efficient lighting leads to diminished consumption. The very contrary is the truth.

LEDs use a lot less energy per lumen produced; according to IHS Market, a consultancy, LED lighting uses an average of 40 percent less power than fluorescents, and 80 percent less than incandescents, to produce the same amount of light. They determined that "the use of LEDs to illuminate buildings and outdoor spaces reduced the total carbon dioxide (CO2) emissions of lighting by an estimated 570 million tons in 2017. This reduction is roughly equivalent to shutting down 162 coal-fired power plants."

LEDs are an entirely different thing; we use them in entirely different ways that nobody ever dreamed of, and we use more of them. Lighting has become so cheap that it has turned into a bauble, into decoration. When it comes to lighting, to paraphrase Stanley: it is wholly a confusion to suppose that more efficient lighting leads to diminished consumption. The very contrary is the truth.
