The Keystone KT-Rkit20PS-8CP-8CSCV-DIM-8 LED retrofit kit does not require a ballast.
This device is designed to be connected directly to 120V AC power. The product's specifications and installation instructions confirm that it operates on a universal 120-277V input and has its own integrated driver. During installation, you must bypass and remove the existing ballast from the fixture.
