On the contrary - the introduction of efficient LEDs has led to insane stuff like decorative building facade illumination which nobody would think of doing with incandescents, just because of replacement effort and energy usage. But with cheap LEDs the operating costs drop to the point where such an application becomes viable, and we get a new source of demand (and light pollution)

You're begging the question, which is not adding to the discussion.

Saying efficiency leads to increased usage is not the same thing as saying increased usage balances efficiency 100%.

It reminds me of people who argued that airbags and ABS lead to people taking more risk when driving. That may be a real effect, but nevertheless, casualties have declined.
