Overview

The Sylvania 20673 CF26DD/E/835/ECO is a 26-watt compact fluorescent lamp sold in a 25-pack, designed for commercial and institutional environments where G24q-3 4-pin fixtures are already installed. Producing 1,710 lumens at a 3500K neutral white color temperature, it delivers a balanced light that's neither too warm nor too cool — making it well-suited for offices, hallways, retail displays, and healthcare facilities. The ECO designation signals reduced mercury content, which is an important consideration for organizations managing environmental compliance and disposal protocols.

With a rated life of 12,000 hours, each lamp offers extended service between replacements, which is particularly valuable in high-ceiling or hard-to-access fixtures where lamp changes are labor-intensive. The 25-pack format is geared toward maintenance departments and facility managers who need to keep consistent stock on hand. While LED retrofits are increasingly available for this socket type, the Sylvania 20673 remains a practical and cost-effective choice for buildings that are already wired with compatible electronic ballasts and where a full LED conversion isn't yet justified.

Key Features

EFFICIENT LIGHT YOU CAN COUNT ON: This 26W 4-pin compact fluorescent bulb is dimmable and designed for electronic ballast fixtures. Plug-in G24q-3 base. A direct upgrade for recessed, task, and showcase lighting.

CRISP, HIGH-QUALITY LIGHT WITH 82 CRI: Rare earth phosphors deliver accurate, natural-looking color in a neutral white 3500K tone. High CRI means colors and surfaces look true - great for retail, task, and accent lighting where light quality matters.

20,000 HOUR LIFE - HALF THE MAINTENANCE: Lasts up to 20 times longer than a standard incandescent bulb and twice as long as many standard CFLs. With 86% mean lumen output maintained, brightness stays consistent well into the lamp's lifespan.

UP TO 75% ENERGY SAVINGS VS. INCANDESCENT: At just 26W, this 4-pin CFL bulb uses about a quarter of the energy of a comparable incandescent. Pair with an electronic dimming ballast to push savings even further when full brightness isn't needed.

DIMMABLE CFL BUILT FOR DEMANDING APPLICATIONS: Ideal for recessed downlights, showcase lighting, exit signs, offices, boardrooms, classrooms and hotel lobbies. A reliable 4-pin light bulb built to provide long-lasting, controllable light.

Frequently Asked Questions

It uses a G24q-3 4-pin base, so you'll need a compatible fixture or ballast designed for that socket type.
Each lamp is rated for 12,000 life hours, which can translate to several years of use depending on daily run time.
The 835 means 3500K color temperature, which produces a neutral white light that sits between warm and cool — suitable for offices, retail, and general commercial spaces.
Dimming depends on the ballast in your fixture. These 4-pin compact fluorescent lamps require a compatible electronic ballast, and dimming capability is determined by whether that ballast supports it.
The ECO designation indicates this lamp meets stricter standards for reduced mercury content compared to standard compact fluorescent lamps.
