GE 33890 12-Inch Circline Fluorescent Cool White

The GE 33890 FC12T9 Circline Fluorescent Bulb is a 32-watt circular tube designed to deliver bright, efficient lighting in large spaces where overhead illumination is essential. With a 1,950-lumen output and a 4100 Kelvin cool white color temperature, it produces a clean, neutral light that is well suited for garages, basements, workshops, and utility rooms. The 12-inch circular form factor fits standard circline fixture sockets via its 4-pin G10q base, making it a straightforward replacement in compatible ceiling and wall-mounted fixtures.

Durability is a key advantage of the GE 33890. Rated for up to 12,000 hours of operation — roughly 5.5 years at 6 hours of daily use — it minimizes the inconvenience and cost of frequent bulb changes in hard-to-reach fixtures. GE's fluorescent lamps are a long-established standard in commercial and residential lighting, known for consistent light quality and low operating costs over the life of the bulb. For anyone maintaining circline fixtures in their home or workspace, the 33890 offers dependable, bright performance at a modest wattage.
