The illumination would last only a few minutes at one location before the mirror required repointing. Reflect Orbital says the technology could extend solar power production after sunset, illuminate construction areas and assist rescue teams working in darkness.

Flare guns already do this for a lot cheaper. They even come in a choice of colours.

The company has also argued that reflected sunlight could provide temporary lighting without diesel generators or permanent ground infrastructure.

Sure it just requires that you build a giant precision mirror array, launch it into orbit, and then constantly monitor and position it from the ground, but god damn if you won't need a bulky, polluting flashlight ever again.

What an absolute fucking joke of a proposal. Yeah, let's blanket the earth in mirrors so that we can light up some random construction site temporarily.

Well, it's true that if you need to illuminate a site for two and a half minutes but can't build anything on the ground, it's a ~~great~~ solution. Is it the best solution? Maybe not. Is it a solution? You bet it is.

We have portable energy sources. They're pretty efficient. Especially comparable to an orbital launch.
