The HF-Performer EII PL-T/C/R/T5c is a sustainable, slim, and high-frequency electronic ballast designed for a wide range of CFL applications. It is ideal for applications that require high energy efficiency. The HF-Performer EII series features a robust design, meets all relevant international safety and performance standards, and is energy-efficient (CELMA EEI A2). The ballast is primarily intended for indoor use. For outdoor applications, the fixture should at least comply with Class I and must be adequately protected against water and dust. The installation should also be protected against lightning strikes or other necessary electrical safety measures required for such typical installations and applications.
