Our take on the Satco S6500 FC8T9/CW/RS 22W T9 Cool White 8-inch Circline Fluorescent Light Bulb

The Satco S6500 is a 22-watt T9 circline fluorescent bulb with an 8-inch diameter and a cool white light output. It is a direct replacement lamp for fixtures built around the FC8T9 circline format, such as round ceiling and vanity fixtures, magnifying task lamps and some older shop lights. Its main draw is the standard circline footprint and the four-pin base that fits those sockets. Rivals in this format differ mainly in color temperature and wattage, so match the lamp to the ballast and socket your fixture uses.

Questions and answers

Will this fit my round ceiling fixture?
It fits fixtures made for an 8-inch FC8T9 circline lamp with a four-pin socket. Check the old lamp's markings and pin count before ordering.
What color is the light?
It is cool white, a brighter, bluer white than warm white lamps. That suits kitchens, bathrooms and task lighting more than cozy living spaces.
Does it need a special ballast?
Yes. It runs on a ballast rated for 22W FC8T9 circline lamps. If the fixture's ballast is failing, a new lamp may still flicker or fail to start.
Is it dimmable?
Only if your fixture's ballast is rated for dimming. Most standard circline fixtures are not, so treat it as a non-dimming lamp unless you know otherwise.
How should I dispose of it?
Fluorescent lamps contain a small amount of mercury. Take it to a local household hazardous waste or bulb recycling point rather than the regular trash.
How does it compare with LED circline replacements?
LED circlines use less power and last longer, but many need the ballast bypassed or removed. This lamp is a straight swap for an existing fluorescent setup.
