Great for key lighting and fill, the 4ft Double is one of the most versatile products in the Kino Flo product range and was one of the first products developed by Kino Flo more than 25 years ago. The 4′ Double System was designed as a soft light source that could be plugged into the wall on location. With its narrow profile and size, the Single could approximate the quality of light from bounced sources without losing set space. The first thing to note about the Single System is that it consists of four components: Single 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.
