Electric Judgment

Electric Judgment was a Force technique used by Jedi such as Plo Koon, and possibly Luke Skywalker.

It showed up as yellow or green energy instead of blue or white; appearance-wise it was like the dark side power Force lightning. An example of it being used for instance, Plo Koon would shoot lightning from his fingertips to wound enemies. A possible reason for this not being a widely used power is because of its similarities to the dark side power causing a moral issue among Jedi.

It was believed that Grand Master Luke Skywalker used this power, or a variation of it, aboard Shimrra's Citadel during the battle against Shimrra Jamaane in an attempt to save his niece and nephew from the Slayers; his powerful version sent green sparks coruscating over the body of a Slayer, causing him to convulse. Electric Judgment was also used by other members of the New Jedi Order, but was extremely controversial. Electric Judgment was sometimes called "emerald lightning".

Behind the scenes
This power, in the New Jedi Order series, was referred to as "emerald lightning." In Destiny's Way, it is said that Jacen used this power because of his familiarity with Force Shock (he used it against Vergere in Traitor). Luke probably was able to use this power because of his long years of meditation on the light side. Jacen said very clearly that it did not kill enemies, but it sapped their strength and will power. He asserts that the Vong he used this power on hadn't been killed, "... the murderous form of lightning was a dark side weapon – but they wouldn't be waking for a long time."
