What this bulb is and who it suits

This 22 watt GE circline fluorescent tube delivers 1100 lumens at 4100 K cool white. The G10q four-pin base fits compatible fixtures in garages, basements or large work areas where soft bright light helps with eye-intensive tasks. Rated life is 12000 hours or about 5.5 years at six hours daily use.

Installing it and common issues

Installation is a simple push-and-twist into a matching G10q socket; the tube seats in one orientation only. The main problem arises when the existing ballast is worn or mismatched, causing flicker or failure to start. Verify the fixture is rated for 22 watt FC8T9 tubes before fitting.

Light output and limits

At 1100 lumens and CRI 60 the tube comfortably lights sizable open spaces such as workshops or rec rooms. It runs out of reach in very high ceilings or areas needing higher colour fidelity, and the single 8 inch diameter tube cannot be ganged for more output without additional fixtures.

Questions about this item

How can I confirm the 22 W circular fluorescent tube is operating correctly after installation?

The bulb should deliver 1100 lumens of cool white light at 4100 K from the G10q 4-pin base without flicker, matching the rated 12000-hour life when used six hours per day.

What comes in the package and is any additional component required?

One FC8T9 T-9 Circline tube is included; a compatible G10q 4-pin ballasted fixture operating at 61 volts must be supplied separately.

Which version should I choose for a standard 8-inch circline fixture?

Select the 22 W FC8T9 model with G10q 4-pin base, 4100 K colour temperature and 1100 lumen output — the only specification offered for this form factor.
