Need advice RSM130d light upgrade

[KillerKlownFish]

I'm thinking of getting LED for my RSM103d.
I need some help/info on what to get:
EcoTech Marine Radion XR30w Gen3 LED Light Fixture

Or
EcoTech Marine Radion XR15w Pro LED

I saw this and am considering doing this mod with either XR15w or XR30w

I am leaning toward the XR15w and doing the same mod.
