Advance ICN-2S28-T Fluorescent Ballast, 2-Lamp
This 2-lamp ballast is designed for 28W T5 applications with a programmed-start electronic control. It supports 120/277V input, making it suitable for commercial retrofit projects and small office fixtures where energy efficiency matters. Best for budget-conscious installations that still require reliable starts and a solid power factor. A potential limitation is its lower wattage, which isn’t ideal for higher-output HO configurations.
Best for: small to mid-size T5 installations needing reliable starts and a good power factor without high ballast complexity.
Advance ICN-2S54-T Centium Ballast, 2-Lamp
This Centium ballast supports 2-lamp T5 configurations up to 54W (F54T5HO) with 120/277V input. It’s well-suited for medium-size offices, classrooms, or retail fixtures requiring HO performance and reliable startup. Its strengths include a familiar Centium family design and electronic operation. Consider this as a better choice when upgrading older 54W setups that require consistent lamp life and efficient power use.
Best for: HO lighting upgrades where two lamps at 54W are needed and a versatile voltage range helps align with existing wiring.
GE GE254MVPS-A UltraStart? T5 Watt-Miser 2-Lamp
The UltraStart 2-lamp ballast is positioned for T5HO Watt-Miser efficiency, with 67562 model numbers indicating a compact, electronics-driven solution. Best for installations that prioritize compact form and straightforward wiring, particularly where space is limited. A noted limitation is product origin; some buyers may prefer domestically manufactured options when available.
Best for: fixtures needing space-saving, easy-to-wire ballast with reliable starting performance.
Advance Centium ICN-2S54T35I – 2 Lamp HO Fluorescent Ballast
This 2-lamp, 54W HO ballast emphasizes a programmed-start approach with a 1.02 ballast factor, designed for consistent performance in higher-output fixtures. It’s best for facilities that require stable light output across longer duty cycles, such as hallways or work areas. A potential caveat is compatibility with specific lamp brands or end-user fixtures; verify lamp pairing before purchase.
Best for: higher-output two-lamp installations needing steady light and reliable ballast factor.
Sunlite SB254HO/MV Electronic Ballast
The Sunlite SB254HO/MV is a multi-volt electronic ballast that operates 1–2 lamps, including F54T5HO, FC40T5, FT55W/2G11, or CF50W/2G11. It runs on a broad input range (120–277V) and uses Program Start technology with quiet, low-noise operation. Best for flexible installations requiring compatibility with multiple lamp types and reduced acoustic impact. A limitation is the need to match lamp types precisely to avoid incompatibilities.
Best for: multi-lamp configurations needing versatility across lamp types and wide voltage input.
Buying Guide
What should you look for when selecting a two-lamp T5 ballast?
- Voltage range: Choose ballasts that support your supply, typically 120/277V for commercial sites.
- Lamp type compatibility: Ensure the ballast supports F28T5, F54T5HO, HO variants, or FC40T5 as needed.
- Ballast factor: A higher ballast factor means more light per watt; match to fixture goals and energy targets.
- Starting method: Programmed Start reduces wear on lamp electrodes and improves life, but is more common in electronic ballasts.
- Size and mounting: Consider the physical footprint and whether the ballast fits existing fixtures and housings.
- Compatibility: If upgrading, verify that the ballast works with your current lamps and ballasts family to simplify maintenance.
Frequently Asked Questions
- What is a two-lamp T5 ballast best for?
– It suits fixtures designed for two T5 lamps, balancing light output and energy efficiency for offices, schools, and retail lighting. - Why choose an electronic ballast?
– Electronic ballasts offer quiet operation, instant start, and higher efficiency compared with magnetic equivalents. - What does “programmed start” mean?
– It initiates lamp ignition in a controlled sequence to extend lamp life and stabilize performance. - Can I mix lamp types with a ballast?
– Not typically; ballasts are designed for specific lamp types and wattages. Verify compatibility before pairing. - Is a higher ballast factor always better?
– Higher ballast factors produce more light per watt but may impact energy use; choose based on fixture needs. - Do these ballasts support 277V?
– Some do; if your installation uses 277V, confirm that the ballast specifies 120/277V before purchase.
