It provides a secure, low-resistance electrical connection point for medium bi-pin fluorescent lamps in standard fluorescent lighting fixtures. The internal shunt maintains circuit continuity when a lamp is removed or fails, a key function for instant-start fluorescent ballast systems. Electricians and lighting maintenance technicians install this lampholder as a direct replacement in commercial, industrial, and residential fluorescent fixture applications.\u003c\/p\u003e\u003cp\u003eThis lampholder is suited for use in fluorescent lighting fixtures that run medium bi-pin lamps on instant-start ballast circuits. The shunted design is specifically required for instant-start ballasts, which apply full voltage across the lamp pins without a preheating cycle. It is not appropriate for use with programmed-start or rapid-start ballasts, which require non-shunted lampholders. Typical applications include troffer fixtures, strip lights, and wrap-around fluorescent luminaires found in commercial, retail, and light industrial environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eInternal shunt maintains circuit continuity when the lamp is absent or fails\u003c\/li\u003e\n\u003cli\u003eMedium bi-pin socket configuration for standard T8 and T12 fluorescent lamps\u003c\/li\u003e\n\u003cli\u003eWhite housing finish for a clean appearance in exposed-fixture installations\u003c\/li\u003e\n\u003cli\u003eCompact single-unit form factor for straightforward replacement installs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement shunted lampholder for fluorescent fixtures using medium bi-pin instant-start ballasts.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with NEC requirements. Always disconnect power at the breaker and verify the circuit is de-energized before removing or installing lampholders. Confirm that the ballast in the fixture is an instant-start type before installing a shunted lampholder, as mismatching shunted holders with programmed-start or rapid-start ballasts can reduce lamp life or cause ballast damage. Secure wiring connections fully before restoring power.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSocket Type\u003c\/strong\u003e: Medium Bi-Pin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShunt Type\u003c\/strong\u003e: Internal Shunt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHousing Color\u003c\/strong\u003e: White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity Per Unit\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: LEVITON TELCOM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 23151-LU\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LEVITON","offers":[{"title":"Default Title","offer_id":51560506622258,"sku":"23151-LU","price":17.07,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/leviton-telcom-23151-lu-fluorescent-bi-pin-lampholder","provider":"Voomi Supply","version":"1.0","type":"link"}
