Pessimists know the “rebound effect”: improvement in efficiency leads us to do more of the thing. More illumination for example. This (partially) counteracts the good effects.
The lower operating costs of LEDs allows people/organizations/govt to leave the lights on longer or all night at a reduce costs compared to filament bulbs.
This is often to the detriment of migratory birds.
That’s totally true, though, in this case with LEDs I feel like the rebound effect is less of a problem here. The LEDs are not only using less electricity, but they’re far brighter with addition to using less electricity for that brightness. It means that even if somebody decides to fill their room with 5 LED lamps with 806 lumens instead of 1 incandescent bulb, they’ll still waste less energy - in addition with 5 LED lamps of 806lm making your room look like the sun is shining inside.

Lights Out encourages LED light users to turn them off at night.
