Luke Skywalker in particular was able to utilize a Emerald Lightning instantaneously kill his targets. The rogue Jedi Master Kenth Hamner used lightning on the Jedi he defeated during his rebellion against the Jedi Order, in order to make sure they could not swiftly awaken.
Yes he has. What he used was a variant of force lightning called “Emerald Lightning” which is supposed to be similar to Plo Koon's “Electric Judgement”.
Originally Answered: Why wasn't Luke physically disfigured by Palpatine's force lightning in Return of the Jedi the way Palpatine was in Revenge of the Sith? Simple answer is often the correct one. Because Palpatine was in complete control. He wasn't actually trying to kill Luke yet.
He may have assumed he would have more time to train Luke before then, or that Luke would be skilled enough to manage. Second it might be that Yoda was so at peace or so one with the force by his death that he either could foresee the outcome of the fight or was willing to accept things as they happened.
Vader relies on the complex life support system of his suit to survive and it happens to be very vulnerable to electrical discharges. So, if Vader ever had unleashed Force lightning, there's a good chance it would've caused his suit to short circuit, thus, killing him.
Darth Vader can not use force lighting, because of his severed arms. Robotic hands can't summon the force lighting. However Darth Vader can still use other forms of the force, such as force choke.
Mace Windu, with his lightsaber combat form Vaapad, could reflect the lightning back to its source with a "superconducting loop". It required tremendous effort on the reflector's part, however, as seen in Windu's battle with Palpatine; Windu was seemingly able to overcome Palpatine's lightning.
While Jedi could create Force lightning, like Sith, they choose not to use that power due to its association with the dark side and immoral nature. Despite being equally as strong in the Force, one innately Sith ability that Jedi in the Star Wars franchise do not wield is Force lightning.
Palpatine's face was left disfigured after fighting Mace Windu, but despite Star Wars' medical technology, he never tried to heal his scars. In Star Wars: Revenge of the Sith, it was revealed that Emperor Palpatine's face wasn't just the product of old age but also scarring from fighting the Jedi.
Gray Jedi commonly demonstrated their skills with both Light and Dark side Force capabilities. For example, the capacity to construct a lightsaber from scratch, along with unique Force talents such as Force lightning.
Force lightning, also known as Sith lightning or dark rays, was an offensive power that Force users could conjure through the dark side of the Force.
Darth Bane's lightning, for example, would often electrocute his opponents to death on contact. Galen Marek was another Force-user who could channel lightning that would kill on contact.
1 Darth Sidious
There has been no Sith, as powerful, meticulous, nor as evil as the Emperor himself, Darth Sidious. As previously mentioned, Sidious trained in the Dark Side by Darth Plagueis before Sidious killed Plagueis in his sleep, making Sidious a Sith Master.
Why couldn't Maul produce Force Lightning? Because he was weak. “Darth” Maul isn't even a Sith, he's an assassin.
Force lightning is a dark side ability used to torture, disfigure, and even kill one's victims. Blue in color, Sith shoot Force lightning from their hands by calling on their hatred and aggressive feelings. However, while a deadly weapon, it is not unstoppable.
Flow-Walking is perhaps one of the most dangerous abilities that a Force user can wield. This rare Force power allows users to view the past and the future. Once Flow-Walking has commenced, those powerful in the Force can even alter some events that transpire, to change the course of the future.
17 Force Light
Only the most powerful of Sith lords can withstand the power of Force Light, making it one of the most powerful Force abilities present in the entire franchise. It can also be used in places plagued by the dark side of the force to either contain or expunge it from the area.
Through his duels with Darth Sidious and Count Dooku, it was well known that Yoda could absorb and deflect Force lightning with his palms.
Some Jedi are explicitly shown using red lightsabers in Legends, however. This includes Adi Gallia, Even Piell, Depa Billaba, A'Sharad Hett, and even Luke Skywalker.
So, all Force users had the inherent ability to use the power. Yes, that meant that Jedi could use the Force choke too.
Either way, while Vader can use most other Force abilities, Force Lightning needs to be channeled, and Vader's limbs are explicitly not connected to the Force. The Star Wars: Episode III - Revenge of the Sith Visual Dictionary confirms Darth Vader cannot use Force Lightning, and even suggests this is the reason why.
Darth Sidious
He is most famously known for his powerful Force-lightning, which he uses to torture and kill his enemies.
Weakness: Electricity
Darth Vader possessed the skill to use Force lightning, but the limitations of his suit prevented this. A lot of the systems that were keeping Darth Vader alive were maintained by electricity, which is why Force lightning was so destructive towards him.
Abrams' movie handles Force Lightning. When Rey taps into the dark side of the force on Pasaana and uses Force Lightning, she feels frustrated after apparently losing Chewbacca (Joonas Suotamo) to the First Order and being bested by Ben Solo/Kylo Ren (Adam Driver) in a Force tug of war.
