All the features of the 4Bank 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 4Bank is a high output, high frequency electronic ballast with universal input voltage from 100-240VAC, that can operate 
four 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.

Notice we haven’t used the word “dimming” to describe lighting control.  The reason is that dimming changes a lamp’s color temperature and color balance.  The 4Bank ballast has individual switches so that each lamp can be turned on/off.  Additionally, the lamps can be operated in a high output/standard output mode.  This combination controls light levels without the color shift issues you have with dimming.

Our 4Bank DMX ballasts can be run manually like the standard 4Bank ballast or via a separate DMX control board.  The 4Bank DMX ballast uses five DMX addresses. Four addresses control lamps 1-4 and the 5th address controls the 4ft/2ft setting.

In addition, each 4Bank DMX ballast (457 Series) has an “Auto Terminate” feature.  The last fixture that does not have an XLR cable attached to the DMX “Out” port will automatically terminate.  This can be a timesaver as it takes the guesswork out of knowing which DMX ballast is the last one that needs to be “closed” or “terminated” for proper DMX signals.

The Kino Flo 4Bank & 4Bank DMX ballast accomplishes all this and still out-performs tungsten lighting instruments when it comes to energy efficiency. In other words, the ballast uses 1/3 the power to produce the same amount of soft light as incandescents. The 4Bank and 4Bank DMX ballasts draw only 2.6A at 120VAC and 1.4A at 230VAC. The ballast works reliably under most normal conditions, but it's also trustworthy in more harsh conditions, such as extreme cold. The ballasts are 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.
