The Kino Flo Mega Double Ballast is a high output, high frequency electronic ballast that can operate two lamps (6ft or 8ft) 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. A special heat-sink design and custom electronic engineering ensure 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 designated as HO/Std (High-Output/Standard Output) 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 Mega Double Ballast accomplishes all this and still out-performs tungsten lighting instruments 10 to 1 when it comes to energy efficiency. In other words, the Mega Double uses 1/10th as much power to produce the same amount of soft light as incandescents. The Mega ballast works reliably under most normal conditions, but it's also trustworthy in more harsh conditions, such as extreme cold. The Mega ballast series is designed to operate at temperatures from 14F to 122F (-10C to +50C).
