Fluorescent Ballasts-T9

Keep compatible circline fixtures in service with Halco electronic ballasts for T9 fluorescent lamps. This category includes one-lamp and two-lamp models with 120V input and rapid-start operation, giving you options for different circline fixture configurations.

Use the full ballast part number and fixture label to guide your replacement. Match the supported lamp combination, wattage and number of lamps, then check the wiring and available mounting space. The E1CR22RS/120/PT and E2CR72RS/120/PT serve different lamp configurations, so review the specifications for the model you need.
