I hate Reflect Orbital so very very much. They are trying to provide expensive, dangerous "help" for problems that already have better, cheaper, less destructive processes in place.

The one thing this article fails to mention is not only could the light from orbit go out at any second, it would be constantly moving, making all the shadows slowly swing around the light source's motion. I've never done any search and rescue, but this seems extremely unhelpful.
