Overview

The GE 11084 is a T9 circline fluorescent light bulb designed as a direct replacement for fixtures that use the standard 4-pin G10q base. Operating at 22 watts, it produces 1400 lumens of warm-toned light — enough output for general illumination in kitchens, bathrooms, laundry rooms, and other household spaces where circline fixtures are commonly installed. The warm color temperature creates a softer, more inviting ambiance compared to cool-white alternatives, making it well suited for areas where comfort and relaxation are priorities.

With a rated lifespan of 5.5 years at 6 hours of daily use, the GE 11084 provides long service intervals between replacements. The T9 tube measures 8.25 inches in length with a 1.1-inch diameter, fitting standard circline fixture housings. As a fluorescent lamp, it offers better energy efficiency than incandescent circline options while maintaining the form factor compatibility that existing fixtures require. For homeowners maintaining circline light fixtures, this bulb delivers dependable brightness and a warm light quality at a low running cost.
