Buying Guide
- Compatibility: Confirm lamp types (F32T8, F25T8, F17T8, F40T8) and number of lamps (3 or 4) per ballast to match your fixtures.
- Voltage range: Many ballasts support 120–277V. Ensure the chosen model aligns with your supply voltage and any local electrical codes.
- Start method: Instant-start ballasts provide faster lamp ignition but may have higher restraint on lamp starting current. Probe your fixture’s needs and lamp type for best performance.
- Certification and safety: Look for UL/cUL, RoHS compliance, thermal protection, and whether the ballast is suitable for remote mounting if your layout requires it.
- Installation: Consider ballast weight, mounting dimensions, lead length (e.g., 18 AWG leads up to 18 ft remote mounting), and whether you need plug-and-play replacements or more involved wiring.
- Durability and environment: For indoor/outdoor use or damp environments, verify ratings (Class P, Type 1 Outdoor) and enclosure requirements.
- Bulk purchasing: If replacing multiple fixtures, consider bulk packs (e.g., 10 packs) for cost efficiency and quick replacement planning.
- Retrofit vs. new install: Some ballasts are optimized for retrofits with mismatched lamps; assess whether your current lamp mix will benefit from a parallel connection approach.
- Brand and support: Choose reputable brands with clear warranty information and readily available replacement parts to minimize downtime.
