Overview
The Spartan Lighting HPS400/100 is a 400W high-pressure sodium ballast kit designed for industrial, commercial, and horticulture lighting systems. This magnetic ballast unit features a constant wattage autotransformer (CWA) circuit that maintains stable arc voltage and lamp wattage across multiple input voltages. The kit arrives complete with pre-wired capacitor, ignitor (starter), mounting brackets, and hardware—making installation straightforward in retrofit or new-build applications.
