The 4-Bank System was designed as a soft light source that could be plugged into the wall on location. With its narrow profile and size, the 4-Bank could approximate the quality of light from bounced sources without losing set space. The first thing to note about the 4-Bank System is that it consists of four components: 4-Bank Fixture, Mounting Plate, Ballast, and Extension Cable. It was designed in this manner to allow the greatest flexibility when working on film production where the gaffer and DP are constantly being challenged to light unique locations and problem-solve at a moment’s notice.
