A fluorescent light ballast is the essential component in any fluorescent lighting system, responsible for providing the initial voltage to start the lamps and regulating the current to keep them running safely. When a ballast fails, your lights can flicker, hum, or stop working entirely. This collection contains high-quality replacement light ballasts designed to extend the life of your existing fixtures and restore their performance.
Signs You Need a New Light Ballast
If you're experiencing issues with your fluorescent fixtures, a failing ballast is the most common cause. Look for these clear warning signs:
- Flickering or Strobing: Inconsistent light output that is often visible to the naked eye.
- Audible Humming or Buzzing: A loud, persistent noise coming directly from the light fixture.
- Slow Startup: Lamps that take an unusually long time to turn on or that flicker for a while before stabilizing.
- Dim or Discolored Light: Bulbs that appear dimmer than usual or have darkened ends, even if the bulbs are new.
- Bulbs Burning Out Quickly: If your fixture is going through fluorescent tubes faster than it should, the ballast is likely delivering improper power.
How to Choose the Right Ballast for Fluorescent Lights
Finding the correct replacement is crucial for a successful repair. Match these key specifications to your old ballast or fixture requirements.
- Match the Lamp Type: Ensure the new light ballast is compatible with your fluorescent bulbs (e.g., T8, T12, T5, or CFLs).
- Check the Number of Lamps: Select a ballast designed to operate the exact number of bulbs in your fixture (e.g., 1-lamp, 2-lamp, 4-lamp).
- Verify the Input Voltage: The ballast's input voltage must match your building's power supply, typically 120V for residential or 120-277V for commercial applications.
- Choose a Starting Method: Most modern ballasts are "Instant Start" for maximum energy efficiency or "Programmed Start" which is gentler on lamps, making them last longer in high-use areas.
