BTW guys, i've been re-reading the Jedi vs Sith: The Essential Guide to the Force book, and in the part where it lists the force-sensitives abilities, it says this about sith lightning:
Force lightning causes excruciating pain as it weakens and individual's life, and is nearly impossible to deflect. Because of the power's obviously negative aspects, it's no wonder various Jedi Orders forbade its use. However, some jedi peacekeepers have refused to dismiss or suppress what they considered to be a natural asset to their arsenal of powers.
Then it goes to say how Plo Koon used it on some mission to Metellos, before he was appointed to the Council, in order to save a child who was taken hostage by the subject he was tracking. But he says he didnt embrace the darkside when he used it. Interesting that later in the book in the sith chapter, sith lightning is taught as a weapon to knowingly and deliberately cause great pain and eventually kill its victim.
Anyways, the book is a nice read if you can get your hands on it.
