It supports lamps ranging from 35 to 150 watts and uses an R, HX circuit configuration, making it a fit for a wide range of HPS ballast assemblies. Weighing 0.3 pounds, this ignitor is a compact component that integrates into existing HID ballast systems. Licensed electricians and lighting maintenance technicians install this part during ballast servicing or full HID fixture rebuilds.\u003c\/p\u003e\n\u003cp\u003eThis ignitor is suited for high pressure sodium HID lighting systems found in commercial, industrial, and outdoor area lighting applications. The 55-volt rating and R, HX circuit type apply to a specific class of HPS ballast designs commonly used in streetlights, parking lot fixtures, warehouse high-bays, and similar installations. Its single-lamp design keeps it targeted to one-lamp-per-ballast configurations standard in most HPS fixture types.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e55-volt rated ignitor for high pressure sodium HID circuits\u003c\/li\u003e\n  \u003cli\u003eCompatible with HPS lamps from 35 to 150 watts\u003c\/li\u003e\n  \u003cli\u003eR, HX circuit type for targeted HPS ballast compatibility\u003c\/li\u003e\n  \u003cli\u003eSingle-lamp configuration matches standard one-lamp HPS fixture designs\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.3 pounds for easy handling during service calls\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement ignitor for single-lamp, 55-volt high pressure sodium HID ballast assemblies using an R, HX circuit configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician following NEC guidelines. Always de-energize the fixture and confirm voltage is absent at the ballast terminals before handling any ignitor or ballast component. Allow HPS lamps to cool fully before servicing, as residual heat and pressure in the lamp envelope can present a hazard. Verify circuit type and voltage rating match the existing ballast before installing the replacement ignitor.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLamp Technology\u003c\/strong\u003e: High Pressure Sodium (HPS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBallast Type\u003c\/strong\u003e: HID\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 55 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWattage Range\u003c\/strong\u003e: 35 to 150 watts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCircuit Type\u003c\/strong\u003e: R, HX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Lamps\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PHILIPS ADVANCE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: LI551H4IC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PHILIPS ADVANCE","offers":[{"title":"Default Title","offer_id":51695843442994,"sku":"LI551H4IC","price":112.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0591d1318ffa47e9d7617a51e2eebada.jpg?v=1788338721","url":"https:\/\/voomisupply.com\/products\/philips-advance-li551h4ic-hid-ballast-ignitor-55v-hps","provider":"Voomi Supply","version":"1.0","type":"link"}
