Five years of development and quality testing by experts in lamp-ballast compatibility went into the Hortilux Platinum Series Digital Ballast Dual 1000W Combo to ensure its excellence. The ballast’s Clean Cool™ Technology channels airflow to reduce dirt and dust accumulation on critical electronic components, and has a 120 Hertz, low frequency square wave form. It also comes equipped with a Hortilux LU1000B/HTL/EN Super HPS lamp, a pre-wired Sun System® receptacle, 120V cord, five year ballast warranty, and an ETL Certification for fire and electrical safety. This 1000W 120/240 volt electronic ballast has a high power factor with flicker-free steady state operation and extended ground contact in the lamp plug for maximum safety, and is also generator ready.
