The FEIT ELECTRIC FC12/840/LED is a 20-watt LED circular lamp designed as a direct replacement for fluorescent circline lamps in commercial and residential lighting fixtures. It delivers 2000 lumens at a 4100K cool white color temperature, providing clear, bright light suited to task and general ambient applications. The Gx10q-4 four-pin base allows direct installation into compatible circline sockets without wiring modifications. Rated for 25,000 hours of service life, this lamp significantly reduces replacement frequency compared to standard fluorescent circline options. It is non-dimmable and requires no ballast driver modification in supported fixtures.
This lamp is appropriate for use in ceiling-mounted circline fixtures found in offices, kitchens, utility rooms, and light commercial spaces. The 12-inch diameter form factor matches the standard FC12 circline profile. Electricians and lighting maintenance technicians install this lamp during fixture retrofits or direct lamp-for-lamp replacements where a cool white output is specified. Package quantity is four lamps per unit of measure.
Designed as an OEM-style replacement for FC12 circline fluorescent lamps in fixtures equipped with a Gx10q-4 four-pin socket. Confirm fixture socket type and non-dimmable circuit compatibility before installation.
Installation should be performed by a qualified electrician in accordance with NEC requirements. Power off the circuit at the breaker before removing the existing lamp or accessing the socket. Align the four pins with the Gx10q-4 socket and seat the lamp fully before restoring power. Do not install this lamp in dimmable circuits or fixtures requiring a ballast-driven circline lamp without confirming compatibility.
