Does the elevator shaft wall lamp need to be embedded?

no need. When the elevator is installed, it is only necessary to lay pipes on the track side of the elevator shaft and install them openly, and it is not necessary to embed them when installing the wall lamp of the elevator shaft. Elevator refers to the permanent transportation equipment that serves several specific floors in the building, and its car runs on at least two rigid tracks perpendicular to the horizontal plane or with an inclination angle less than 15 from the vertical line.
