The power ring's most distinctive effect is the generation of green, solid-light constructs, the precise physical nature of which has never been specified. The size, complexity, and strength of these constructs is limited only by the ring-bearer's willpower; whatever the wearer imagines, the ring will create. When active, a power ring will encase its user in a protective, life-supporting force field. This force field allows the user to fly, travel through inhospitable environments (outer space, underwater, etc.), and enter hyperspace in order to move vast distances quickly. The ring also generates its wearer's Green Lantern uniform: the uniform appears over their normal attire and vanishes at the user's will. The uniform varies from Lantern to Lantern, based on anatomy, personal preference, and the social norms of their race. Power rings also appear to be highly advanced computers; they are able to talk to and advise the wearer as to various courses of action, as well as act as a universal translator. The ring can also scan for energy signatures or particular objects. For more intricate problems or problems that require a back logged history (Of a planet, person, group, ETC.), the ring connects with the main power battery on Oa which is the "main" computer, of sorts. Power rings are able to give off electromagnetic radiation of various frequencies. This radiation can be focused by the wearer into a beam, similar in appearance and effect to a powerful laser. The ring is also capable of producing an electrical current. Less frequently used capabilities include splitting atomic nuclei and manipulating subatomic particles (thereby transmuting chemical elements). A power ring is also capable of creating fully functional duplicates of itself.
