Our take on the Feit Electric 8 in. 15-Watt T9 Cool White 4100K G10Q Circline LED Light Bulb

This is a Feit Electric 8-inch T9 circline LED replacement bulb with a G10Q 4-pin base, rated 15 watts and 1,400 lumens in cool white (4100K). It is a direct LED swap for 22-watt circline fluorescents in ceiling fixtures, shop lights and magnifier lamps. Frosted glass diffuses the light, and the 25,000-hour rating is roughly 10 times a fluorescent tube's life. No current price was provided, so check the live comparison for where it sits against its recent range.

Questions and answers

Will this fit my existing circline fixture?
Only if the fixture takes an 8-inch T9 circline with a G10Q 4-pin base. Check the old bulb's shape and connector before ordering; standard screw-base sockets will not work.
Is it really a 22-watt replacement?
Feit rates it as equivalent to a 22W circline fluorescent, and it produces 1,400 lumens. Actual perceived brightness depends on the fixture's diffuser and ballast.
Does it need a ballast?
It is designed as a drop-in for fixtures with the original magnetic or electronic ballast. If the fixture hums or flickers, the ballast may be the cause, not the bulb.
How long will it last?
Feit rates it at 25,000 hours, about 10 times a typical fluorescent circline. Real-world life varies with heat and how often it is switched on and off.
Is 4100K too blue for a living space?
4100K is a neutral cool white, brighter and cooler than warm white. It suits kitchens, garages and workshops better than bedrooms or living rooms.
When is the best time to buy?
Prices on this bulb move with store promotions and multipacks. Compare the per-bulb price across stores and buy when it dips below its recent range.
