The bottom edge of an LED wall light fixture should be installed 30 to 36 inches (approximately 76 to 91 cm) from the vanity surface. This height ensures that the light directly hits the user's face and avoids shadows caused by angles that are too high or too low.
Most LED wall light fixtures are fixed to the wall using screws or nails. While this installation method ensures stability and security, improper installation can leave marks on the wall, especially when removing the fixture, as screw and nail holes often leave marks on the wall.
