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 more harsh conditions, such as extreme cold. The ballast series is designed to operate at temperatures from 14F to 122F (-10C to +50C).

In extremely cold temperatures, the ballast may not strike the lamp(s) initially because the lamp may need to warm up. Switch the ballast to Off, wait seven seconds and try again. If the ballast does not strike after two or three attempts, turn off the ballast, check that the extension and harness connections are secure and re-strike. Once operating for a few minutes, the lamps should re-strike instantly.
