As a Core \u0026amp; Coil ballast in the Advance 71A family, it provides the ballast function for fixtures that use high-intensity discharge lamps, delivering regulated current to the lamp to maintain consistent light output and lamp life. The model number 71A5770-001D corresponds to the 250 W metal halide variant in the Core \u0026amp; Coil lineup and is marketed under the Philips Advance brand. This ballast kit is specified for 250 W maximum bulb wattage and uses traditional magnetic ballast technology, which relies on a laminated iron core and windings rather than switching electronics. It is suitable for installations that require a 250 W MH ballast with M58 compatibility, such as legacy industrial or outdoor luminaires that historically used this ballast family. The 71A5770-001D designation helps service technicians match replacements for legacy HID fixtures that specify ANSI M58 ballast requirements.\u003c\/p\u003e\u003c\/div\u003e","brand":"ADVANCE","offers":[{"title":"New","offer_id":51657026765102,"sku":null,"price":55.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_b456b6ec-e2fe-4c8f-9d71-ffbd6a64dc22.jpg?v=1769465317","url":"https:\/\/plgautomation.com\/products\/industrial-71a5770-001d-core-coil-ballast-kit","provider":"PLG Automation ","version":"1.0","type":"link"}
