Philips Advance Core & Coil Ballast Kit 71A5792-001D

The Philips Advance 71A5792-001D is a core and coil ballast kit designed for operating a single 250W metal halide lamp (ANSI M58 or M153). This kit includes the ballast, a prewired ignitor, capacitor, and mounting brackets, making it suitable for replacement or installation in high-intensity discharge (HID) lighting systems. It supports multiple input voltages (120V, 208V, 240V, 277V) at 60Hz with a constant wattage autotransformer (CWA) circuit, ensuring stable lamp performance and energy efficiency. Ideal for applications in industrial, commercial, and outdoor lighting such as warehouses, parking lots, and sports facilities, this ballast provides reliable starting and operation in demanding environments. Advantages include multi-voltage flexibility, reducing inventory needs, and robust construction for long service life compared to electronic ballasts, which may be more sensitive to temperature extremes. Drawbacks include higher energy consumption and heat generation versus modern LED drivers. Based on image analysis, the kit appears used, with visible wear on wires and components, but includes original packaging and instructions. No serial number is clearly visible on the faceplate in images. For detailed specs, refer to manufacturer datasheets from Signify (formerly Philips Advance). Estimated market value for used condition is $50-100 USD, based on comparable online listings.
