It depends on the type of lamp and the strength of the magnet.
An incandescent lamp works literally by running current through the filament to heat it. Parts of the bulb might be magnetic, so if the magnet were ridiculously powerful it might deform or break them.
Fluorescent and Neon lamps use ionization, so although I haven't tried it, I'd bet a reasonably strong magnet might affect them.
If you have an old CRT-based television or computer monitor you can see how this works by placing a magnet near it -- note, this can cause permanent effects to the picture quality, so either keep the magnet at a distance where the effect is minimal or use a CRT you don't care about.
LED lamps are so small and well-constructed that I think they're more like incandescent lamps -- a really powerful magnet might damage them, but otherwise is unlikely to affect them.

What happens when you break a magnet into smaller pieces?
You get a bunch of smaller magnets and you will still have north pole.
What happens when you break a magnet?
As you break a magnet, the remnant (broken piece) shall still remain a magnet with the same properties and poles. However, there is only so far a magnet can be broken. Visualize a magnet. Now imagine to have a knife that would keep cutting the magnet into half. It will reach a point that cutting the 'magnet' further would yield into a particle with no magnetic charge whatsoever. This is called a magnetic domain. Cutting a magnetic domain further would yield into a charge-less particle as it would be obviously incorrect to state that an atom of a magnetized steel bar would still remain a magnet.
Why does the needle of a compass point south when it's put on a bar magnet?
When a compass needle is placed near a bar magnet, it aligns itself with the magnetic field created by the magnet. The compass needle is a small magnet itself, with its north pole attracted to the south pole of the bar magnet and repelled by its north pole. If the compass needle points south, it indicates that the bar magnet's south pole is near the compass's north pole, demonstrating the fundamental property of magnetic attraction and repulsion. Thus, the orientation of the compass needle reflects the magnetic field direction of the bar magnet.

What happens if you put a heart in the wrong way?
It does not beat
What happens if you put a lava lamp in the microwave?
The lamp will explode.
What happens when you put a magnet next to iron?
it attracts
What happens when you put a magnet on yourself?
nuthin at all you will have no effect
What happens if you put a timepiece close to a magnet?
Usually, nothing.
What happens if you put a magnet on copper?
Nothing. Copper is not magnetic.
What happens when you put jam on a magnet?
Jam/Jelly has no effect on the magnet or its magnetism, but it will cause the magnet to become sloppy and sticky.
What happens when you put a magnet wrapped in cling film nearby iron and sulphur?
The magnet will attract the iron, but will not attract the sulphur.
What happens if you put a magnet to your memory card?
all your memory will be gone forever
What happens if a direct current is put through a coil suspended between the poles of a magnet?
The coil will align itself with the magnetic field (poles) of the magnet.
What happens if you put a magnet on an I-pod nano?
It destroys the hardware inside the ipod and it stops working
What happens when you put magnet on a disk?
Unless you scratch the disk while placing the magnet on the disk, then nothing will happen. A magnet would have to be powerful enough to extract the hemoglobin from human bloodcells to be able to effect the disk.
What happens when you rust a magnet?
the magnet gets weaker
