So in the Starbound Discussions area there is a thread about the fact the Light Packs are essentially useless for 3/4 of the planets you go on, as cosmetic items don't produce any effects, in this case well, light. Which to me is annoying as to fully upgrade to the Xenon pack you need to go on planets requiring the EPP, so by that stage it's effectively useless for the majority of the exploring you're doing. So I'm suggesting that having light effects still function from cosmetic skins. Or Have Light upgrades to the EPP by using the Light packs, or it's composite parts, in an upgrade to the EPP and ditch the Light i, ii and iii Augments.
