Buying Guide
Key factors to consider when choosing a 4-lamp T12 ballast
- Voltage compatibility: Most 4-lamp T12 ballasts operate at 120V or 120/277V. Confirm your site’s supply to avoid rewiring.
- Startup type: Instant start reduces warm-up time but may affect lamp life in some fixtures; programmed start can be gentler on lamps but may take longer to strike.
- Lamp type support: Ensure the ballast lists the exact lamp types you intend to run (F32T8, F25T8, F17T8, F40T12, HO variants, etc.).
- Safety and certifications: Look for UL or CSA listings and RoHS compliance for reliability and compliance with local codes.
- Mounting and wiring: Check dimensions, mounting footprint, and lead length to prevent fit issues. Remote mounting should be within the recommended distance.
- Installation complexity: Some ballasts include pre-wired leads and simpler remote wiring; consider your skill level and wiring access.
- Maintenance and replacements: Favor ballasts with readily available replacement parts and replacement guidance from reputable brands.
