The 30 inch square fixture is 1 3/4 inches deep and weighs 24 pounds (without lamps). Edison is arrayable to form large, low-resolution video walls. Steel straps running down the back sides support fixtures hanging below. The front panel is solid 1/10″ aluminum, free of visible hardware, and can be powder coated in a variety of colors (stock is silver).
