How to Choose the Right Fluorescent Ballast

Match the ballast to your lamps (example: F32T8, F40T12, F54T5HO, or CF26). Check the lamp type and wattage printed on the existing tubes. -
Number of Lamps
Select 1-lamp, 2-lamp, 3-lamp, or 4-lamp ballasts according to the fixture configuration. -
Start Method
โข Instant Start โ Best for lights that stay on for long periods
โข Rapid Start โ Good general-purpose option
โข Programmed Start โ Ideal for frequent on/off cycles and occupancy sensors (longest lamp life) -
Voltage
Choose 120V for standard residential/commercial or universal 120โ277V for broader compatibility. -

Frequently Asked Questions
What does a fluorescent ballast do?
A fluorescent ballast provides the high voltage needed to start the lamp and then regulates the current so the lamp operates safely and efficiently without burning out.
Electronic vs. magnetic ballasts โ which should I choose?
Electronic ballasts are quieter, more energy-efficient, run cooler, and produce less flicker. Magnetic ballasts are older technology, heavier, and still used in some existing fixtures. Most new installations use electronic.
How do I know which ballast I need?
Look at the existing ballast label or the lamps currently installed. Note the lamp type (T8, T12, etc.), number of lamps, wattage, and voltage. You can also search by the old ballast model number for a direct cross-reference.
Can I replace a magnetic ballast with an electronic one?
Yes, in most cases. Electronic ballasts are common drop-in replacements, but always verify lamp compatibility, wiring, and mounting dimensions.
Do these ballasts work with LED tubes?
Some Type A (ballast-compatible) LED tubes can operate with existing fluorescent ballasts. For maximum efficiency, many users prefer ballast-bypass (Type B) LED tubes and remove the ballast entirely.
Do you offer bulk or project pricing?
Yes. Contact us or create an account for volume discounts on cases and large projects.
