What Stands Out
Energy Efficiency
The PLC-18W bulbs consume only 18 watts of power, significantly reducing electricity costs while providing bright illumination, making them an eco-friendly choice for energy-conscious consumers.
Versatile Compatibility
Designed to replace Sylvania 20668 and PL-C 18W/841/4P/ALTO bulbs, these fluorescent lights easily fit into existing fixtures, ensuring hassle-free upgrades for various lighting applications.
Long Lifespan
With an extended operational life, these bulbs provide reliable lighting over time, diminishing the need for frequent replacements and contributing to lower maintenance costs for both residential and commercial users.
Product Details
- DIRECT REPLACEMENT CONFIDENCE (Compatibility & Cross-Reference) FITS YOUR FIXTURE — This 18-watt double tube compact fluorescent CFL bulb features a standard G24q-2 4-pin base, providing a direct drop-in replacement for fixtures using Sylvania 20668 (CF18DD/E/841/ECO), Philips PL-C 18W/841/4P/ALTO, and GE F18DBX/841/ECO4P. If your fixture currently holds any of these bulbs, this Circle replacement installs without any rewiring or fixture modification.
- BALLAST COMPATIBILITY (The #1 Customer Question) BALLAST-OPERATED DESIGN — This 4-pin G24q-2 CFL is designed to operate with compatible electronic and magnetic ballasts rated for 18-watt PL-C double tube lamps. The 4-pin configuration requires a ballast — it is not a direct line-voltage plug-in. Verify your fixture uses a G24q-2 socket (not G24d-2, which is 2-pin) before purchasing. For replacement questions, the base type can be confirmed by counting the pins on your existing bulb.
- LIGHT QUALITY & APPLICATIONS 4100K COOL WHITE LIGHT WITH 82 CRI — Delivers crisp, neutral cool white illumination at 4100 Kelvin with an 82 Color Rendering Index (CRI), producing accurate, natural-looking light that reduces eye strain in task-oriented environments. Ideal for offices, conference rooms, commercial retail spaces, hallways, kitchens, utility rooms, storage areas, and recessed downlight fixtures. The 841 designation confirms 4100K color temperature with 80+ CRI — a commercial-standard specification.
- LIFESPAN & VALUE 12,000-HOUR AVERAGE RATED LIFE — Each bulb is rated for up to 12,000 hours of average operation, meaning fewer replacements, lower maintenance frequency, and reduced per-fixture cost over time. This 4-pack provides dependable, long-lasting performance for both residential and commercial applications where reliable uptime matters. At 18 watts per bulb, this compact fluorescent consumes less power than equivalent-output incandescent or older fluorescent sources.
