People already complain about the pulsing shadows, the droning hum and the optics. I can't wait to hear them also complain about the nightly LED flicker.

More seriously though it should be possible to use LEDs just bright enough to deter birds while also not totally annoy most humans. At that point light pollution and insects might still become a problem though.

Ooo, we could use LED's that project an image as it goes around and sell that image space to advertisers. /s

Then we can calculate a literal cost per impression, and the unit is birds.

Actually sounds like a cool art project!

Maybe using UV LEDs? Birds can see higher wavelengths than us.

People will start complaining about cancer risks.
