A rough calculation based on a small (less than km) mirror:
Light from a small mirror will have the sam divergence as the incident light. The Sun’s angular diameter is about 10mr. So a mirror in a 300 km orbit will create a 3km diameter spot on the earth
So the intensity of the illumination, compared to Sunlight, is just the ratio of the mirror area to ...
