Product Description

Multi-voltage 4-tap electromagnetic ballast kit for one 400W LU400 high-pressure sodium lamp (ANSI S51), field-configurable for 120V, 208V, 240V, or 277V service. The constant-wattage autotransformer (CWA) circuit holds lamp output steady through line-voltage swings, making it a workhorse for parking lots, warehouses, and other large-area HPS fixtures.
