EcoSystem Ballasts
Please note that not all listed models can be used in all regions. Verify that the voltage requirements of the desired ballast matches that of your region. All models listed here are UL and CSA certified, unless otherwise noted.

Lutron stopped selling ballasts at the end of 2023.
Lutron fluorescent ballasts have been discontinued and are no longer available, with very limited exceptions for only a short period. If you currently have fluorescent lamps, now is the time to upgrade. The Lutron Ballast Retrofit Kit by C-Flex is a simple way to upgrade at your own pace and budget. Kits provide compatible Lutron replacement drivers and LED lamps and enable you to keep your fixture, wiring and control system.
