Overhead florescent light is now dimmer, why?
 

I have in the kitchen a pair of overhead light fixture. Each fixture has two
florescent tubes and both fixtures are controlled by the same light switch.

Tonight one of them suddenly dimmed and remain about half as bright as the
other one. No flickering, just half as bright. I thought the tubes may be
going bad so I went and bought two new tubes - same wattage same brand. No
difference. Still dimmed.

Any idea what could be the problem? Do I need a new light?

You could have a wiring problem, or a bad ballast. At least now you
have two spare lamps.

You might try switching the ballast and see if the problem follows the
ballast. Be careful and make really sure the power is off before doing any
wiring work.

Overhead florescent light is now dimmer, why?
 

I did recently tinker with another lamp next to the kitchen that has a
different ligth switch. I replaced the original toggle switch with a
dimmer type. I think I did it right, it works...

I have no idea if the kitchen overhead lights are connected to this
other lamp in some way or not, is it possible one can affect the other?
or when you say wiring you mean the wiring of the florescent lamps? If
so then no, nothing has happened to it's wiring, other than hurricane
Wilma we have a series of power up power down cycles.

Thanks,

MC

Does the dimmer fixture have only one tube lit? Are there starters in the
fixture? If so, try replaceing them.

The you could have a bad ground and that would be a wiring problem. You
also could have a wiring problem inside the lamp, between the sockets and
the ballast. I doubt if the other light is connected with this problem.

No, both fixtures are operated by the same toggle switch. Each fixture
has two tubes. I don't know what you mean by "starters"?

I replaced both tubes with new ones, no change in results. Still very
dimmed lights. When I replaced both tubes in one fixture, both tubes
are lit but dimmed.

Thanks,

MC

Near one end of each tube is there a small silver colored cylinder
sticking out? There should be a flat surface on the fixture between the
2 ends of the tube. The starter (if there is one) will be sticking out
of a hole in that flat surface near one end of the tube.

I don't think a bad starter would cause your symptoms.
