What do Green Lanterns use as their main weapons in the DC series Lanterns?

Green Lanterns use power rings as their main weapons in the DC series Lanterns.

The series follows Green Lanterns, intergalactic peacekeepers whose rings give them extraordinary powers. Power rings are the primary weapons of the Green Lantern Corps and are the source of the Lanterns’ abilities. Their presence connects the grounded detective plot to the larger comic-book mythology.

Lanterns is more realistic in tone than many Green Lantern stories, but the production team emphasized that the show remains steeped in the lore. Hal Jordan and John Stewart possess power rings, and later marketing showed Jordan using his ring to create green constructs.

A power ring is not the same thing as a normal piece of jewelry in the series. It is a weapon and technological or mystical tool connected to the Corps. The show’s mystery takes place on Earth, but the rings explain why Jordan believes the murder may be connected to extraterrestrial events and why the investigation can expand beyond an ordinary crime case.
