Is the "mounting plate" centered at the back of the light unit, or is it located somewhere else (i.e., top or bottom of light unit)?A. The Sonneman 3681 mounting plate is located at the back of the light in the center. Thanks for your question and have a great day!
Can this light be mounted horizontally?A. The Sonneman 3681 is both an up and down so directional orientation will not hinder the efficacy.
