Ballasts Fluorescent & HID Light Ballasts – Magnetic, Electronic & Dimming Options

Ballasts

Ballasts support fluorescent and HID lighting systems that still need magnetic, electronic, dimming, metal-halide, or high-pressure sodium replacement components. This path sits outside the main egress fixture flow, so compare Outdoor Lighting for complete exterior fixtures, Wall Packs for building-mounted LED replacements, and Emergency Lights when the project is really about battery-backed life-safety lighting.

Use this Ballasts collection as a focused buying path, then compare related categories when the application, environment, mounting, or compliance requirement changes.

Trust & Policies

01

Existing fixture

Confirm the existing ballasts application, fixture type, lamp or driver details, and replacement goal before ordering.

02

Electrical compatibility

Check voltage, wiring diagram, battery or ballast type, connectors, and installation instructions.

03

Runtime and output

Verify emergency runtime, output needs, and whether the replacement path still meets egress requirements.

04

Listing and environment

Confirm listing, damp/wet rating, ambient temperature, and local project acceptance.

05

Replacement path

When compatibility is uncertain, compare a complete emergency fixture replacement instead of forcing a part swap.

Final compliance depends on the selected product listing, installation, project documents, and local AHJ approval.

How do I choose the right Ballasts?

Start with the existing fixture or part number, then confirm voltage, wiring, battery or ballast type, ratings, and installation instructions.

When should I replace the full fixture instead?

Replace the full fixture when compatibility is unclear, the housing is aging, or a complete LED emergency unit is simpler to maintain.

Are these code compliant?

They can be when properly listed, compatible, and installed for the application. Confirm final acceptance with the local AHJ.
