Our take on the T9 Round Fluorescent Circline Lamp, 22 Watts

The T9 is a circular fluorescent lamp (circline) rated at 22 watts and 1,250 lumens. It is a replacement tube for fixtures that take a 22W circline, such as some desk lamps, magnifier lamps and ceiling fittings. Output is roughly equivalent to a 75W incandescent bulb. No current price was provided, so check the live comparison before buying.

Questions and answers

Will this fit my lamp?
Only if your fixture takes a 22W circline tube with the same pin base and diameter. Check the old tube's wattage and the pin spacing before ordering, since 22W rings come in more than one size.
Is 1,250 lumens bright enough?
It is about as bright as a 75W incandescent bulb, which suits desk, magnifier and small ceiling fixtures. For a large room you would want more than one.
Can I replace it with an LED circline?
Sometimes. LED replacements exist, but many need the ballast bypassed or removed. A straight fluorescent swap is simpler if your fixture is working.
How do I dispose of the old tube?
Fluorescent tubes contain a small amount of mercury, so take them to a household hazardous waste site or a store that accepts them. Do not put them in regular trash.
Why does it flicker or hum?
That usually points to the ballast or starter in the fixture rather than the tube. If a new tube still flickers, have the ballast checked.
When is it cheapest?
Prices for replacement tubes move little, but multipacks often cost less per tube. Compare the per-unit price across stores before buying.
