Are there Light side powers and "Light Jedi"?

Question

To put into context, Force powers such as Force Lightning are considered exclusively Dark side powers. Dark Jedi are defined as Force users who have succumbed to the Dark side, yet are not officially a member of either the Jedi or Sith Orders. I assume most readers understand the distinction between Dark Jedi from Jedi or from Sith, so I shall not elaborate further.

So first, what are the equivalent Light Side-exclusive powers? I've seen Light Side-only powers in games, but I hope to cross-reference with actual lore to be certain they aren't Light Side exclusive for game balancing and mechanics alone. Other than that, the Light Side is described as more powerful than the Dark Side, relying on knowledge instead of sheer power to prevail, though is harder to master. This leads me to believe there do exist ways of using the Force through the Light to be learnt that cannot be gained through the Dark.

Secondly, are there "Light Jedi"? Force users who are aligned with the Light Side or simply do not use the Dark Side, but aren't members of the Jedi or Sith Orders. Ahsoka Tano comes to mind, but technically she had Jedi training. Dark Jedi, however, are generally considered to be inferior in training and Dark Side expertise compared to Sith, so I'm not sure if Ahsoka can be considered a legit Light Side equivalent of Dark Jedi by definition. Care to enlighten me on this? Thanks!

Answer 1

The most obvious example of a light side power would be Force ghosting:

The ultimate goal of the Sith, yet they can never achieve it; it comes only by the release of self, not the exaltation of self. ( ROTS novelization )

If we bring Legends EU into it, there are other powers such as "Wall of Light": http://starwars.wikia.com/wiki/Wall_of_light

Answer 2

With the restructuring of canon, much of this is not very clear. But this wiki article does name a number of light side powers, noting that

Light-sided Force abilities are virtually all defensive and passive in nature. While there are light side abilities for increasing ones strength or courage, or incapacitating an enemy, none of them are truly aggressive (with the notable exceptions of Electric Judgment, Sever Force, and Combustion).

As far as non-Jedi "light side" users, there certainly were some, though they may be further from Jedi than Dark Jedi were from Sith:

• The Jensaarai

• The Fallanassi

• The Aing-Tii Monks

• The Baran Do

All of whom showed varying levels of light-side affiliation. Additionally, there were Gray Jedi, which may refer to Jedi who skirted boundaries or operated outside the Order, though in both cases they were still technically Jedi.
