Buying Guide

Match ballast to lamp type

Confirm whether you need T12, T8, or HID ballast compatibility so the ballast supports your lamp's starter and operating characteristics

Check voltage and mounting

Prioritize universal-voltage or 120–277V ballasts for flexible installation and confirm mounting and wiring fit for your fixture

Instant-start vs electronic

Choose instant-start fluorescent ballasts for simple, low-cost starts and electronic ballasts for improved efficiency and reduced flicker

OEM fitment for vehicle HID

For automotive HID replacements, verify OEM part fitment and plug-and-play compatibility with the vehicle make and model

Durability and heat tolerance

Look for sealed housings and quality connectors on HID units and electronic components rated for the fixture's ambient temperature
