|This article lacks an official name. "Light Crystal" is simply how it is referred to as, due to the popularity in the fandom or how it's mentioned in-story.|
First seen on Ultraman Tiga, as the "Tiga Crystal" (ティガクリスタル Tiga Kurisutaru) is always located on the forehead of certain Ultras in the Neo Frontier Space World. Since Tiga gained the power to Type Change by absorbing the attacks of other Dark Ultras, it can be assumed his crystal regulates the powers within his body, altering the ratios to change his type. It is similar to the Beam Lamp seen on some Ultras, such as Ultraseven.
The light crystal seems to have direct access to an Ultra's Inner Light as Yanakargi was able to draw out Tiga's energy through his crystal instead of his Color Timer.
Two of Geed's game exclusive forms, Mugen Crosser and Mighty Trekker which utilizes the assets of Ultraman Tiga and Ultraman Dyna respectively, possess a light crystal on its forehand that looks similar to Dyna and Tiga's.

- Dark Abilities: Due to Camearra's nature as a Dark Giant, she used hers to channel dark energies instead of the power of light, it was only seen during her Demonzoa transformation.
- During filming, some of the show's lighting effect changes the color of Tiga's light crystal into gold.
- According to designer Hiroshi Maruyama, the light crystal that was first displayed by Tiga was originally to reflect the sunlight during lighting effect.
- Although being Ultras from a different point of origin, Ultraman Rosso's and Ultraman Blu's form changes are also regarded as Type Changes.
