About this item

• DIRECT REPLACEMENT — Drops in for Sylvania 20672 (CF18DD/E/835/ECO) and Philips 38332-3 (PL-C 18W/835/4P/ALTO). Also replaces Panasonic FDS18E35/4 for WhisperLite fan models FV-08VQL4, FV-11VQL4, FV-15VQL4, FV-11VHL1, FV-08VKL1, FV-08VKSL1, FV-08VKML1, FV-05VFL2, FV-08VFL2, FV-11VFL2, and FV-08VLS1. Requires G24q-2 4-pin base — verify your fixture uses 4 pins before ordering.
• BALLAST COMPATIBLE — Works with standard electronic and magnetic ballasts rated for 18W G24q-2 4-pin compact fluorescent lamps. This is a ballast-dependent lamp, not a direct-wire bypass bulb. If your ballast has failed, replace the ballast — this lamp will not operate with a failed ballast.
• 3500K NEUTRAL WHITE — Produces a balanced, clean light that is neither warm yellow nor stark daylight, making it well suited for offices, hotel lobbies, retail spaces, conference rooms, kitchens, and commercial task lighting where comfortable, accurate illumination matters.
• 10,000-HOUR RATED LIFE — Long average rated life reduces replacement frequency in hard-to-reach fixtures including ceiling fans, recessed housings, and commercial overhead luminaires. The 8-pack keeps replacement stock on hand for ongoing residential or facilities maintenance.
• ENERGY-EFFICIENT COMPACT FLUORESCENT — At 18 watts, these double tube CFL plug-ins deliver strong output while drawing less power than incandescent alternatives of comparable light output, making them a practical choice for fixtures that require plug-in CFL lamps.
