Leviton Telcom 26725-402 18W 4-pin Cfl G24q-2 Base

Product Description

The LEVITON TELCOM 26725-402 is an 18-watt 4-pin compact fluorescent lamp (CFL) designed for use with G24q-2 and GX24q-2 lamp bases. This plug-in CFL is intended for fixture applications that require a dedicated electronic or magnetic ballast to drive the lamp. The 4-pin configuration indicates a lamp designed to operate on a separate ballast circuit, making it a direct replacement for electricians and lighting maintenance technicians working on commercial or residential ballast-driven luminaires. At 18 watts, this lamp fits the standard G24q-2 and GX24q-2 base footprint used across a wide range of downlights, wall sconces, and troffer-style fixtures.

This lamp is suited for interior lighting applications in commercial, institutional, and residential settings where G24q-2 or GX24q-2 base fixtures are installed. Typical installations include recessed downlights, pendant fixtures, and wall-mounted luminaires that use ballast-driven plug-in CFL technology. Electricians and lighting maintenance personnel handling lamp replacements or fixture retrofits will find this an appropriate drop-in for ballast-compatible sockets. Unit of measure is each, sold individually.

Key Features

• 18-watt 4-pin compact fluorescent lamp for ballast-driven fixtures
• Compatible with G24q-2 and GX24q-2 base sockets
• 4-pin base requires a separate compatible ballast — not for use in self-ballasted sockets
• Plug-in design allows straightforward lamp replacement without rewiring
• Sold individually (1 lamp per unit)

Compatibility

Designed for use in fixtures with G24q-2 or GX24q-2 lamp sockets that are paired with a compatible external ballast rated for 18W 4-pin CFL lamps.

Installation Notes

Installation should be performed by a qualified electrician in accordance with applicable NEC requirements and local codes. Always de-energize the fixture and verify power is off at the breaker before handling the lamp or accessing the socket. Confirm that the existing ballast is rated for an 18W 4-pin CFL with a G24q-2 or GX24q-2 base before installing — mismatched ballasts can cause premature lamp failure or no-start conditions. Do not install this lamp in a self-ballasted or screw-base socket adapter.
