Widelite 4-RIRB-B Autotransformer Ballast

The WIDELITE 4-RIRB-B Autotransformer Ballast regulates the power supplied to 400 W HID lighting fixtures in industrial and commercial environments. As a magnetic autotransformer ballast (Mod B), it provides voltage regulation and lamp starting for HID lamps, enabling reliable lamp performance across varying line conditions. Designed for flexible installation, it accepts 120–240 VAC input, operates at 50/60 Hz, and supports fixture or remote mounting in warehouses, parking lots, manufacturing facilities, outdoor industrial lighting assemblies, and large commercial buildings. Enclosure-compatible with industrial lighting fixtures, it is commonly used in HID lighting systems for ballast replacement, retrofit projects, and restoration of existing HID installations by maintenance teams, electrical contractors, and facility managers.
