First, select the exact location on the wall where you want to install the sconce. Hold the sconce base (a black, circular plate is shown in the video) against the wall and use a pencil to mark the positions for the mounting screws. Before drilling, use a stud finder to determine if there is a wall stud behind the marked locations. If you can align the screw holes with a stud, drill pilot holes slightly smaller than your screws into the stud. If no stud is present (as is common with drywall installations), you must use appropriate wall anchors to ensure the sconce is securely stabilized and does not sag or pull away from the wall over time. Drill holes sized for your chosen wall anchors. Insert the wall anchors into the drilled holes, following their specific installation instructions (e.g., tapping in, turning until flush). Finally, align the sconce base with the holes (and anchors), and drive the mounting screws through the base into the wall (and anchors). Tighten the screws until the sconce base is firmly secured to the wall and exhibits no movement. Over-tightening can damage drywall or anchors, so tighten until snug.
