About This Product
If you’ve got a fluorescent light fixture that’s flickering, humming, or just plain dead, chances are the ballast is shot.
This Technical Precision ballast is a direct replacement for the SLI Sylvania 89G457, so you can swap it in and get your light back up and running without replacing the whole fixture.
This is a straightforward part – nothing fancy, just a reliable magnetic ballast that does what it’s supposed to do.
It’s built to meet the specs of the original, so compatibility is solid.
Just make sure to disconnect power, match the wires, and mount it securely in the fixture.
Comes as a single ballast per pack.
It’s a practical fix for workshops, garages, basements, or any space with older fluorescent fixtures.
