Leviton 4015-D4F Lampholder

Add a Reliable Socket with the Leviton Lampholder

The 4015-D4F from Leviton is a medium base twin lampholder designed for multi lamp incandescent fixtures. It is suitable for residential and light commercial fixture manufacturing or repair. Key features include keyless, single circuit operation and a durable black phenolic body.

Key Features and Benefits of This Lampholder

The twin, multi cluster configuration lets one mounting point hold two lamps, which matters for fixtures needing higher output without a redesign. Keyless operation means the lamp is switched from the fixture or a wall control rather than a built in switch, simplifying wiring in custom builds.

Where to Use the 4015-D4F Lampholder

Suited for fixture assembly or repair work on decorative or utility lighting using standard medium base incandescent compatible lamps. Intended for indoor, dry location use typical of residential and light commercial fixtures rather than damp or outdoor settings.

Installation and Compatibility Checks

Mounts using a 1/8 IPS male top and bottom bracket, so confirm this matches the fixture's existing hardware before ordering. As a single circuit lampholder, both lamps operate together and cannot be switched independently.

Additional Buying Context

This lampholder is a practical replacement part for repairing an existing twin socket fixture rather than buying an entirely new fixture, useful for maintaining older lighting where original parts are no longer available.
