Theatre dressing rooms solved this problem a century ago and everyone else has been ignoring the answer ever since. Bulbs ringed around a mirror at face height, close in, throwing light onto the face from every direction at once - it looks theatrical because it is, and it works because shadows have nowhere to fall.
Domestic furniture rarely copies it directly, partly because a ring of exposed bulbs suits a dressing room and not a bedroom. The compromise that does work is two lights, one on each side, level with the face. Two sources from opposite directions cancel each other's shadows, which is the whole principle.
Our master Indian artisans carve the arms as part of the mirror frame rather than fixing brackets to it afterwards, so the wiring runs inside the carved section and nothing is visible. It means the position has to be right before the frame is cut - which is why we ask your seated height at the design stage rather than after.
