The kit ships complete with a dry-film capacitor, pre-wired igniter, mounting bracket, and all required hardware, making it a ready-to-install replacement assembly. Operating on a quad-tap, 4-tap voltage configuration, it accepts 120, 208, 240, or 277 volts, making it well suited for multi-voltage commercial and industrial lighting installations. The circuit type is HX-HPF (high-power-factor), and the ANSI code is M110. Licensed electricians and lighting maintenance technicians are the primary installers of this ballast type.\u003c\/p\u003e\n\u003cp\u003eThis ballast kit is intended for use in fixtures housing 50-watt standard metal halide lamps in commercial, industrial, and institutional lighting applications. Its quad-tap voltage range allows a single SKU to serve multiple panel configurations without requiring separate inventory. The HX-HPF circuit design provides high power factor correction, which is commonly required in commercial facilities to minimize reactive power load. The pre-wired igniter reduces field assembly time during replacement or new construction installs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eComplete kit includes dry-film capacitor, pre-wired igniter, mounting bracket, and hardware\u003c\/li\u003e\n  \u003cli\u003eQuad 4-tap voltage rating: 120, 208, 240, and 277 volts for broad panel compatibility\u003c\/li\u003e\n  \u003cli\u003eHX-HPF circuit type for high power factor correction\u003c\/li\u003e\n  \u003cli\u003eCore-and-coil ballast construction with aluminum winding material\u003c\/li\u003e\n  \u003cli\u003eANSI code M110 for 50-watt standard metal halide lamps\u003c\/li\u003e\n  \u003cli\u003eUL listed for Canada and the United States; RoHS compliant\u003c\/li\u003e\n  \u003cli\u003eMinimum starting temperature of -30 degrees C for cold-environment installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement ballast kit for 50-watt standard metal halide fixtures requiring an M110 ANSI-coded, HX-HPF circuit ballast on a quad 4-tap 120\/208\/240\/277-volt supply.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with NFPA 70 (NEC) and all applicable local codes. Disconnect and lock out power to the fixture at the branch circuit breaker before removing the existing ballast or capacitor. Verify the supply voltage at the panel matches one of the four available taps before making connections. Allow the lamp and capacitor to fully discharge before handling any components.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLamp Type\u003c\/strong\u003e: Standard Metal Halide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLamp Wattage\u003c\/strong\u003e: 50 W\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: M110\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCircuit Type\u003c\/strong\u003e: HX-HPF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBallast Type\u003c\/strong\u003e: Core and Coil\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating (Input)\u003c\/strong\u003e: 120\/208\/240\/277 volts (Quad 4-Tap)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOpen Circuit Voltage\u003c\/strong\u003e: 258 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCapacitor Voltage Rating\u003c\/strong\u003e: 400 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInput Current Rating\u003c\/strong\u003e: 0.64\/0.37\/0.32\/0.28 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFrequency Rating\u003c\/strong\u003e: 60 Hz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCapacitor\u003c\/strong\u003e: 6 microfarads (MFD), Dry Film\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIgniter Type\u003c\/strong\u003e: Pre-Wired\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRegulation\u003c\/strong\u003e: 5 percent\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWinding Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Starting Temperature\u003c\/strong\u003e: -30 degrees C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCapacitor Temperature Rating\u003c\/strong\u003e: 100 degrees C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsulation Class\u003c\/strong\u003e: 200 degrees C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApprovals\u003c\/strong\u003e: UL (Canada and US), RoHS Compliant\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKit Contents\u003c\/strong\u003e: Capacitor, Igniter, Mounting Bracket and Hardware\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 13.0 inches (L) x 4.0 inches (W) x 3.0 inches (H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: China\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: KEYSTONE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MH-50X-Q-KIT-\/A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KEYSTONE","offers":[{"title":"Default Title","offer_id":51284148617522,"sku":"MH-50X-Q-KIT-\/A","price":117.72,"currency_code":"USD","in_stock":false}],"url":"https:\/\/voomisupply.com\/products\/keystone-mh-50x-q-kit-a-50w-metal-halide-hid-ballast-kit","provider":"Voomi Supply","version":"1.0","type":"link"}
