Light

Light is a nano-augmentation which creates a coherent illumination of field of view, enabling the user to navigate dark areas. The source of light are bioluminescent cells within the retinas of eyes. This ability can not be upgraded with Augmentation upgrade canister. It drains Bioenergy at 10 units/minute rate.

Light has only a disadvantage, it can affects an agent's stealth. It can be spotted by enemies, disclosing the nano-augmented location.

JC Denton has this augmentation already installed in 2052 when he begins his first mission in Liberty Island. In 2072, Light does not expend energy, but only illuminates the area immediately around the user. Alex Denton has this augmentation by the time they arrive at the Chicago Tarsus Academy.

Behind the scenes

 * In Deus Ex, an alternative to Light which does not consume energy could be the Dragon's Tooth Sword. However, the weapon creates little light.
