When I placed a lamp next to a mirror where I can see "two lamps", does that double the light output? I know all the light that would have been wasted on the wall is now being returned so is it a yes? (lemmy.dbzer0.com)

The light output is the same. The light "input" you are receiving through your eyes is more, because the light (not all of it though, but nearly) is now reflected towards you instead of partially absorbed by the wall.
