The light is getting dim because the choke is using the energy the lamp should be using. The purpose of the choke is to remove transients; if it is using power at 50 or 60Hz, this is not desirable. My guess is this lamp is using a new energy efficient (not incandescent) light bulb? If this is the case, don't. If this is a choke you added to the lamp, then perhaps it's the wrong type choke (too large inductance). If you added this, it could be that you inadvertently inserted resistance in the lamp wire. Check to make sure nothing is getting hot around your new wiring. A bad solder point could cause this to some degree.
The function of a choke in a lamp circuit is to produce high voltage. In tubelights, the high voltage is essential for ionisation of the gas which is present in tubelights.
It provides an 'inductive kick' to start the lamp, and also limits current to the proper level after the lamp is started.

Anything can make you choke. Mustard, for example, is pretty likely to make a person choke because it can be dangerous in large amounts.
To limit the current through the lamp when the gas ionises and conducts.

Yes, you can choke your enemies.
go to the store buy a lamp, put in you house and there you are!
The inductance primarily serves to limit current flow to the correct level for the tube. It also can be used during startup to provide an inductive 'kick' forming a higher-voltage pulse to start the lamp.
If you choke on it, yes.
Choke it of course!
