thats true if you consider light REFLECTED LIKE IN A MIRROR

but actually its not reflected but once it hits the object light expands like this V

i try to use basic logic

an object i see it cause emits light, light opens like this V, therefore halving distance to an object should appear 4 times brighter besides 4 times bigger(twice bigger in lenght 4 times in surface)

maybe actually colour light is different than sun light?
