dear all
what would be the function of the parallel capacitor use with flood lighting .
and what the causes that damage it?
thank you?

RE: capacitor of the flood lighting

Usually the floodlighting is provided with fluorescent tube. This needs ballast in order to limit the current. The ballast will deteriorate the power factor. In order to fix the problem a capacitor is provided.
The capacitor damage could be produced by voltage spikes. See:
