GE Circline T9 22W 4-Pack Cool White

This four-pack of GE 33774 circline fluorescent tubes delivers 1100 lumens each at 4100K cool white. The 1.1 inch diameter T9 lamps use a 4-pin G10q base and consume 22 watts. Rated life is 12000 hours, equating to roughly 5.5 years at six hours daily use.

Suits garages and basements not dimmable fixtures

These bulbs are built for large open areas such as basements, garages and recreation rooms where broad cool-white illumination is needed. They are not suitable for fixtures requiring dimming, instant full brightness in freezing temperatures, or a higher colour rendering index than 60.

4-pin G10q base decides fit

The single specification that determines compatibility is the 4-pin G10q base; the fixture must accept this exact connector. Voltage is 61 volts and the tube measures 1.1 inches in diameter, so the ballast and housing must match both electrical and physical requirements.
