Advance 10289 – ICF-2S26-H1-LD
Advance 10289 ICF-2S26-H1-LD is a compact electronic ballast designed for 1–2 CFL lamps with 26W capacity. It supports a broad input range of 120–277V and features programmed start operation, which preheats lamps before ignition to extend lamp life. Philips-branded, the unit emphasizes reliability for residential and light commercial fixtures. The ballast is built with a robust construction suitable for demanding environments, and the ICF-2S26-H1-LD model aligns with common CFL configurations to simplify retrofits and new installations alike. It integrates safety compliance and energy-conscious performance for steady lighting.
Advance ICF-2S26-M1-BS
The Advance ICF-2S26-M1-BS is a 1- or 2-lamp CFL ballast rated for 120/277V operation. Its compact metal-case housing provides durability, and the unit supports a variety of quad- and triple CFL configurations, making it suitable for both retrofit and new installations. With a focus on reliability and ease of wiring, this ballast offers stable performance in common CFL lighting setups and aligns with standard 2-lamp CFL fixtures.
Advance ICN-4P32-SC Electronic Ballast
Advance ICN-4P32-SC is designed for four lamps at 32W (T8) and operates on 120/277V. While focused on higher-lamp configurations, its high power factor and 120–277V compatibility make it a strong option for larger CFL lighting schemes. The ballast is engineered for efficient startup and consistent lamp performance, with safety certifications and thermal protection typical of reliable Advance ballast lines. It suits educational facilities, offices, and retail spaces seeking scalable CFL lighting solutions.
Buying Guide
Key considerations when selecting a ballast for CFLs include voltage compatibility, lamp type support, starting method, and environmental conditions. Programmed-start ballasts prolong lamp life by preheating filaments before ignition, reducing wear on lamps and ballast components. Instant-start models offer quick operation at the expense of slightly faster lamp depreciation in some cases. Parallel-lamp connections provide better performance with mismatched lamps and simplify retrofits where lamp types vary.
Other critical factors are safety certifications (UL, cUL, RoHS), thermal protection, and the ability to remotely mount the ballast (up to several feet). For commercial installations, a ballast with a high power factor and low THD minimizes energy waste and electrical noise, improving overall system efficiency. Durability matters as well; sealed or potted housings guard against moisture and dust in challenging environments. When choosing among the options, compare compatibility with the current lamp inventory, installation constraints, and the expected lifecycle costs to maximize return on investment.
In summary, the recommended CFL ballast options above emphasize reliability, safety, and energy efficiency for a range of residential and commercial CFL lighting projects. By focusing on voltage compatibility, starting method, and robust construction, these ballasts help ensure stable, long-lasting illumination for compact fluorescent lamps.
