The tops of wall lanterns should be mounted no higher than the top of the door or no lower than 12'' below the top of the door. Wall lanterns should be mounted securely on a smooth wooden plate set into the siding rather than directly on uneven clapboards or shingles. Ambient light is soft and undefined. It is diffused with the use of low wattage bulbs (25-75 watts). Glare is also reduced by placing the fixture higher or lower than eye level.
