Fluorescent light bulb blinking?

You need to change the ballast out in your lights. Its easy turn off the power and take off the cover. See what voltage it is, see what the serial number is on the ballast (the big black thing). You can find one at almost any supplier. Then cut the wire close to the ballast and wire tie the new ballast to the old wires instead of ordering a whole new frame. A lot more cost efficient. Just match up the colors or the wires and your done. Lot easier than it sounds.

Fluorescent light bulb blinking?

It's a philips brand, 32 watts with a push in 4 pin socket with three tubes.

It has started to blink on and off.

I presume this is a sign that it's reached it's service limit.

I put in a fresh one to replace it and after about a minute it begins to blink as well.

Ideas?

If the fixture is not grounded, that could cause the blinking. Another possibility is if the bulb is cold. Does the blinking stop after the bulb warms up?

Is there a starter? If so, they need to be replaced anytime the lamp is replaced.

It may be the ballast. They tend to last longer than the lamp, but not forever.

There are a couple of things that will cause that to happen. If the device is on any kind of photo cell device, a timer or you have an electrical issue on that circuit. Current may not be fully closed.

The ballast sounds like it is bad

The fixture could be going...especially if it is a fluorescent fixture, they have transformers in them that wear out after time.

Replace the fixture with a REAL lightbulb.
