Hard light

Hard Light, also spelled hard-light, is the Covenant name for Forerunner technology that allows light to be transformed into a solid state to bear weight and do various other tasks. The technology is used in energy bridges as well as to lock Forerunner doors.

It is also used in the construction and composition of Forerunner structures, and as a cutting weapon, such as on the arms of a War Sphinx.
