All the features of the Double fixture would be useless if Kino Flo had not developed its own ballasts that could run the fixture heads remotely. Unlike conventional architectural ballasts that need to operate three feet to six feet from the fixture head, Kino Flo ballasts can operate the fixture heads from up to 75 feet (3 x 25ft extension cables). The Kino Flo Double ballast is a high output, high frequency electronic ballast with universal input voltage from 100-240VAC that can operate two lamps (4ft or 2ft) up to 75 feet between ballast and fixture.

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 as well. Custom electronic engineering ensures stable operation without magnetic hum or cooling fans to interfere with the sound recording on set. There is no delay when switching lamps. The ballast operates the lights on/off instantly. There is also a special Select switch to raise or drop the wattage in the tubes for light output and color control.

Keeping the ballast remote from the fixture and lamps makes the controls more accessible to lighting crews who might need to rig the fixtures into set designs or high up in a lighting grid, but switch them easily from a convenient location on the stage floor. The Kino Flo Double ballast accomplishes all this and still out performs tungsten lighting instruments when it comes to energy efficiency. In other words, the ballast uses less power to produce the same amount of soft light as incandescents.

The double ballast draws only 1.3A at 120VAC and 0.7A at 230VAC. The ballast works reliably under most normal conditions, but it's also trustworthy in
