Leviton Telcom 23151-LU Fluorescent Bi-pin Lampholder

Product Description

The LEVITON TELCOM 23151-LU is a white fluorescent medium bi-pin lampholder with an internal shunt. 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.

This 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.

Key Features

• Internal shunt maintains circuit continuity when the lamp is absent or fails
• Medium bi-pin socket configuration for standard T8 and T12 fluorescent lamps
• White housing finish for a clean appearance in exposed-fixture installations
• Compact single-unit form factor for straightforward replacement installs

Compatibility

Designed as an OEM-style replacement shunted lampholder for fluorescent fixtures using medium bi-pin instant-start ballasts.

Installation Notes

Installation 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.
