    Ballast Replacement

    Posted by Ralph Alberti on Mar 8th 2021

    I had never replaced a ballast before and found that it couldn't have been easier after viewing a demo on YouTube. Worked like a charm!

    This ballast is a manufacturer’s recommended replacement. While this ballast works for traditional T8 fluorescent lamps, it, unlike the original universal ballast, does not work with T8 LED lamps.

    F40T12 ballast

    Posted by Len Fleury on Dec 14th 2020

    Once I color matched conductors, the install went smooth enough for the average homeowner to handle. Suggestion: make the black and white conductors about a foot longer. Other than that, a great little ballast.
