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.

Pros & Cons

👍 Pros

  • 25-pack bulk quantity reduces per-lamp cost and keeps spares on hand for replacements.
  • 1710 lumens from just 26 watts provides strong light output with low energy consumption.
  • 12,000-hour rated life minimizes the frequency of lamp changes in hard-to-reach fixtures.
  • 3500K neutral white color temperature works well across office, retail, and institutional settings.
  • ECO designation means lower mercury content than standard CFL alternatives.

👎 Cons

  • G24q-3 4-pin base limits compatibility to fixtures with matching sockets and electronic ballasts.
  • Compact fluorescent technology lacks the instant-on performance of LED alternatives.
  • 26W CFL output can be matched by lower-wattage LED replacements, making this a less efficient option long-term.
  • Bulk 25-pack is a large commitment if you only need a few replacement lamps.
  • Contains mercury, requiring proper disposal at recycling facilities rather than standard trash.

Frequently Asked Questions

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.
