Though I have to ask the value of illuminating large tracts of mostly uninhabited land. Lighting areas where no humans are around to want the light seems like a proposition that’s mostly useful for further disturbing nocturnal wildlife.
What might be more useful is to illuminate just the areas where a human currently needs to see well. It would hypothetically be both more useful - you can concentrate more light in just the areas you need it - and less expensive.
What would be particularly cool about this hypothetical technology is that it could work equally well under foliage and indoors.

Crops means farmland. Farmland means food. Food prevents people from starving to death.
With global warming, existing croplands will become unusable. We'll need new farmland.
That was the whole point of my post, which also discusses other concerns.
