Life Energy Conduit: The white ring draws on and is connected to the powers of life and creation.
The White Lantern Rings first appeared at the end of the Blackest Night s
aga, as the rings destroyed the Black Lantern Rings controlling the still living heroes, as well as resurrecting certain heroes and villains that were previously dead. White Lantern Rings work just like any other rings, having the same powers. However, Sinestro and Hal Jordan are the only ones shown using the rings' powers to form constructs. Since White is a neutral color in the Electromagnetic Spectrum, it can be assumed that White can overwrite the powers of all other Power Rings if it chooses to. After Sinestro had the Entity removed from him and Hal Jordan took his place as host of the Entity, the White Light overwrote his Green Lantern Ring, along with the rings of any other corps (including Black Lantern Corpsmen). The white rings act as a conduit for the power of the white light of creation. As such they can project and manipulate the white light.
