This 2-light Gaffer kit is a complete lighting set-up in a box. It is designed to keep the elapsed time between setting up and shooting to a minimum. A crew can be on site and shooting an interview in minutes. The 4Bank system was designed as a soft light source that could be plugged into the wall on location and be shooting in minutes. With its narrow profile and size, the 4Bank could approximate the quality of light from bounced sources without losing set space. 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. The 4Bank is a high output, high frequency electronic ballast with universal input voltage from 100-240 VAC, that can operate four lamps with up to 75 feet between ballast and fixture. Dedicated switches allow for individual control of each lamp. The ballast sends a high output current to the lamps to drive the light as brightly as possible. Its high-frequency electronics prevent any type of flicker. Kino Flo's engineering ensures stable operation without magnetic hum or cooling fans to interfere with the sound recording on set.
