Light

Light is a player attribute that boosts the player's level past 20, increasing the damage done by subclass abilities against higher-level enemies. A player's Light can be increased by equipping armor that boosts it.

Rare armor can only give a maximum of +15 Light per piece, giving a total of 60 Light and allowing the player to reach level 24, the highest level attainable without Legendary or Exotic armor.

Legendary Armor sold through the Vanguard, Crucible, or any of the factions give a maximum of 27 Light each. With three of these and one exotic piece of armor, which can give a maximum of 30 Light, one can have a total of 111 Light, allowing the player to reach level 29. Legendary Armor found inside the Vault of Glass can give a maximum of 30 Light. If a player has four pieces of Raid Legendary Armor or three pieces and one Exotic piece of armor, they can reach a total of 120 Light, hitting level 30.
