The Ever-Present Glow of LED Greenhouses

I get that greenhouse windows have to be transparent during the day to let in the sun - so why don’t they add shutters that close at sundown and preserve even more of the LED light inside the greenhouses, reducing the necessary power input and solving the light pollution problem?

Because it’s cheaper to make the lights brighter than the reflective shutter system you are imagining

How does making lights brighter save the problem?
