INTRODUCTION
The reason behind this build is to create a character using nontransmuted Stun Jacks which I have not really found anywhere. Light’s Guardian set is used, so natural option is an Elementalist, which also has great lightning RR and deals massive damage with Wind Devils and Storm Totems. For reduction of cooldown on Stun Jacks dual Spark of Ultos is used (also adds to Wind Devils lifetime). Healing comes from devotions and from striking with DW weapons when Stun Jacks are on cooldown (not necessary - you can kill enemies from distance if you want to). This build kills everything fast so it is a cannon. It deals great lightning and heavy electrocute damage from Stun Jacks, Wind Devils, Rahn’s Might and Storm Totems. It is also glassy - so it is a glass canon 
You will have to use health potions from time to time.
I have other lightning casters here. All my builds are here.

Build uses two Monster Infrequent items - Kaisan’s Eldritch Eye for CC res and Chains of Brandis for vitality converted to lightning. You want affixes that give bonuses to OA and elemental resistance. I used crafting bonus to armor on the helm but you can use whatever you want. Alernative for amulet is Peerless Eye of Beronath.

SR, CRUCIBLE
I play SR with camera pointed away from enemies and I try my builds only in SR 65-66 and SR 80. I play around 10 SR runs per character.
This build has absolutely no problem to kill everything in seconds. If you kite then 20 seconds for the hardest bosses. Easy SR 65-66 if you stay out of harm’s way. You have to learn to play with this character. Facetank for couple of seconds then move away and strike from distance for few seconds then move close again. It is a glass cannon. Performance will greatly depend on your skills. I tried SR 80 with it and it is too glassy for it.
I don’t have a time number for Crucible because I don’t play it.
