Weve simplified the Flip technology by incorporating it into our Flip Series ballast. This technology allows the user to run two separate lights on an alternating 12/12 cycle. Save space and money by consolidating two technologies in to one ballast. The Flip Series is not compatible with the NCCS. Like the Dual Series, the Flip Series has a patented 9-sided design that allows for quicker dissipation of heat without the advent of large, heavy heat sinks. Like all of our ballasts the Flip Series comes with Random Start technology. Random Start uses an algorithm that will start the ballast within a 0-15 second window. This allows for less initial power draw when using multiple ballasts. All Nanolux ballasts are FCC compliant no more RFI problems. ETL listed meeting product safety standards.
