Our take on the GE 22 Watt T9 Circline 8.5in Cool White 4100K Fluorescent Bulb 6-Pack

This is a 6-pack of GE 22-watt T9 circline fluorescent bulbs in cool white (4100K). They use a 4-pin base and Type A ballast, so they are drop-in replacements for many round ceiling fixtures, magnifier lamps and shop lights. The frosted glass gives even light, but the CRI of 60 is low, so colors look dull compared with modern LEDs. No price was provided for this listing, so check the current per-bulb cost against LED circline replacements before buying six.

Questions and answers

Will this fit my fixture?
It fits fixtures that take a 22W T9 circline bulb with a 4-pin base and Type A ballast. Check your old bulb's wattage and pin count before ordering.
Is it dimmable?
No. It is non-dimmable and should be used with a standard on/off switch.
Should I buy this or an LED circline?
LED circlines use less power, last longer and render colors better. Buy this only if you want to keep your existing fluorescent ballast and fixture.
How many bulbs come in the pack?
Six bulbs. The spec sheet lists one bulb included, but the product name and pack describe a 6-pack, so confirm the count on the listing before ordering.
Can it be used outdoors?
It is damp rated and listed for indoor/outdoor use, but it should be in an enclosed damp-rated fixture, not exposed to direct rain.
When is the best time to buy?
Multi-packs like this are often cheapest during home-improvement sales and bulk promotions. Compare the per-bulb price against single bulbs before buying six.
