Advance Transformer 71A6071-001 Core & Coil Ballast Kit is a magnetic HID ballast assembly designed to replace a failed ballast in compatible Philips Advance luminaires. The kit comprises a core-and-coil ballast—laminated core with copper windings—that regulates current to HID lamps and provides the ignition path required for startup. In catalog cross-references, the part is listed as 71A6071-001D in some Deltona/Philips Advance cross-reference tables; the 001D variant is noted to include an integral ignitor, simplifying installation in fixtures that call for an integrated ignitor. This part belongs to Philips Advance's Core and Coil ballast family and is described in cross-reference guides as a magnetic HID ballast, indicating its intended use in traditional HID lighting systems. Use is typical for luminaires designed for magnetic ballast operation where a direct replacement is needed to restore illumination performance.
