Those above are definitely the ones. When I was working on Kenobi's ultimate ability I pretty much universally went after one of those (can't remember which is LS), but honestly after doing that I think if you have any crystal income at all just save those up and buy the impulse detectors. 1800 crystals for 10 is more efficient than using every bit of normal energy towards the gear pieces
You need Aeromagnifiers from Cpit, the ones that come after impulse detectors.
I have 200+ aeromagnifiers. Impulse detectors are much more difficult once your guild has CTR on farm. Obviously a hurdle, but the detectors aren't any easier - you need 180+ of that rare G12 salvage to make the required relic material for a single R8.
Aeromagnifiers are also available in Conquest top 2 crates in hard they payout 5 and 10 you can also get ID in some of the wandering stranger markets but they are expensive

Probably one of those three.
Farm that

You need both, and that doesn’t answer the op.
This does: farm light side normal 9-F

My apologies
If you can't get aeromagnifiers, you probably shouldn't be worrying about R8s in the first place.
Seriously, impulse detectors are by FAR the bigger bottleneck.
