Our take on the Philips T9 4-Pin Circline Fluorescent Tube Light Bulb, White

This is a circular T9 fluorescent tube with a 4-pin bi-pin base, made to drop into ceiling-mounted circline fixtures. It puts out about 1000 lumens, roughly matching a 60-watt incandescent, while drawing far less power and lasting many times longer. The 8-inch ring shape is the main thing to check: it only fits fixtures built for a T9 circline tube, not standard sockets. It suits anyone replacing a burned-out ring light in a kitchen, bathroom, closet or utility fixture.

Questions and answers

Will this fit my ceiling light?
Only if your fixture takes an 8-inch T9 circline tube with a 4-pin base. Check the old tube's shape and pin count before ordering; it will not fit a standard screw socket.
How bright is it compared with a regular bulb?
It produces about 1000 lumens, which is roughly the output of a 60-watt-plus incandescent. That is enough for a kitchen, closet or utility fixture.
Does it need a ballast?
Yes. Circline tubes run on the ballast built into the fixture. If the old tube worked and the new one does not light, the ballast is the likely cause.
How long does it last?
Philips rates fluorescent tubes like this to last up to 10 times longer than incandescent bulbs. Actual life depends on how often it is switched on and the condition of the ballast.
Can I dim it?
No. Standard circline fluorescent tubes are not dimmable in typical fixtures. Use it only in a fixture wired for on/off operation.
How should I dispose of it?
Fluorescent tubes contain a small amount of mercury, so take the old one to a household hazardous waste or recycling drop-off rather than the regular trash.
