Advance 1000W M47 CWA Metal Halide Encapsulated Ballast, Quad 120-277V

Where quiet performance is required across the range of commercial, retail, and institutional applications, Advances encapsulated core and coil ballasts expand on the basic core and coil HID ballast design by encapsulating (potting) the ballasts in a cube-shaped steel can that subsequently carries a Class A or Class B noise rating. At the heart of this product, however, remains Advances exclusive core and coil design and manufacturing process, which insures unparalleled reliability and safety as well as superior performance.
