Enhanced Light Armor costs 4cc to equip (as opposed to the Light Armor's 2cc), it offers more protection without a corresponding loss of speed and/or agility.
In appearance, the Enhanced Light Armour is slightly bulkier than normal Light Armor, although the solid portions are slightly smoother. Headgear and accessories are the same as for Light Armor.
