The lamp in the mirror is a reflection of light from the real lamp. The real lamp is producing light. The mirror lamp is a reflection of this light. The reflection doesnt add to the amount of total light
Yeah, we’re not troll sciencing light out of nowhere, but if the lamp is next to a mirror instead of a wall, the room will have more illumination, because the mirror is reflecting the light emitted by the lamp better than a wall will do.

Will it? Maybe. You are making the assumption that specular reflection is better at reflecting than diffuse reflection, but that is a false assumption. It depends on the reflectivity of the wall and the mirror. A white wall can reflect more light than a mirror.

Let’s define “more”.
