Ballasts and drivers are the unsung workhorses of any commercial lighting system. Whether you are maintaining an older fluorescent installation, retrofitting to LED, or specifying new construction, having the right driver or ballast on hand keeps projects on schedule and prevents costly callbacks.

RelightDepot stocks a broad selection of electronic fluorescent ballasts, HID ballasts, and constant-current LED drivers from leading manufacturers. Electronic fluorescent ballasts are available in T5, T8, T12, and compact fluorescent configurations, with dimming and non-dimming options to suit existing controls infrastructure. For LED retrofit and new-construction applications, our LED drivers cover a wide range of wattages and output currents, including 0-10V dimming, TRIAC/ELV dimming, and emergency battery backup-compatible models. Class P thermally protected ballasts are stocked for applications where UL or NEC compliance requires thermal protection on the ballast itself.

Electrical contractors and maintenance professionals will find the mix-and-match flexibility they need. Many ballasts and drivers ship same-day from stock, and volume pricing is available for larger job orders. Not sure which driver or ballast is compatible with your fixture? Our product specs include compatibility notes and wiring diagrams to take the guesswork out of field installation. When ordering for a large project, list the fixture manufacturer and model number and our team can confirm the correct replacement.

If you are upgrading fixtures as part of a broader energy project, pair your driver selection with the right lamp from our Lamps & Bulbs category, or browse Retrofit Kits for complete drop-in assemblies that include both the driver and the optics. For projects requiring independent dimming control, Controls & Devices carries compatible occupancy sensors, dimmers, and photocells. Facility teams managing large re-lamp programs can also find ballast recycling solutions in our Recycling Containers section.
