Frequently Asked Questions
What is the difference between a ballast and an LED driver?
A ballast regulates current for fluorescent or HID lamps. An LED driver performs a similar function for LED modules or fixtures, usually providing constant current or constant voltage.
What is an emergency ballast?
An emergency ballast contains a battery that automatically powers the fixture for a minimum of 90 minutes during a power outage, meeting code requirements for egress lighting.
What is a sign ballast?
Sign ballasts are specialized electronic units designed to operate high-output T8HO or T12HO lamps commonly used in outdoor and channel-letter signage.
Do I still need starters with electronic ballasts?
Most modern electronic fluorescent ballasts do not require a separate starter. Starters are primarily used with older magnetic rapid-start or preheat systems.
How do I find the right replacement?
Check the label on the existing ballast, driver or lamp for type, wattage, voltage and model number. You can also contact us with the old part number for a cross-reference.
