'''Hard light''', alternatively spelled '''hard-light''' or '''hardlight'''<ref name="Official Site">[http://halo.xbox.com/halo4#!halo-evolved/gameplay/31afe32b-0e07-45c0-9424-3adc6e1eadca '''Halo 4 Official Site:''' ''GAMEPLAY'']</ref> and more formally identified as a '''boson-photon field''',<ref>[http://us2.campaign-archive1.com/?u=8efbd7b88156ac5f6faed8b69&id=4fdccf0da5&e=7be5970a3b '''Mega Bloks''', Special Report: ONI REAP-X]</ref> is a [[Forerunner]] technology that allows light to be transformed into a solid state, capable of bearing weight and performing a variety of tasks. This involves an as-yet unexplained interplay between coherent, high-energy light and gas particles, such as air.

==Applications==
===Basic===
Hard light was used extensively by the Forerunners for a great variety of purposes. Forerunner control panels and interfaces are almost always made entirely of hard light, and can react to the touch of a Forerunner or [[human]] despite their utter lack of mechanical components. [[Light bridge]]s are another basic application of hard light; these bridges are strong enough to bear the load of heavy objects such as a [[Scorpion]] tank, yet can be switched on or off as easily as a normal beam of light. Some of the larger [[Bridge (structure)|conventional bridges]] constructed by the Forerunners also feature support cables made of hard light.<ref>'''Halo: Combat Evolved''', campaign level ''[[Assault on the Control Room]]''</ref> Hard light is also used in the locking mechanisms of Forerunner [[door]]s.<ref name="wages">'''[[Halo: Evolutions - Essential Tales of the Halo Universe]] Volume II''', ''"[[Wages of Sin]]"'', ''page 291''</ref>

===As structural elements===

The most prominent use of hard light is perhaps also its most inconspicuous one; although this is not immediately obvious, hard light construction actually comprises a significant portion of Forerunner architecture. Through the use of highly sophisticated [[holography|holographic]] projection technology, hard light can be crafted to be entirely indistinguishable from physical construction such as metal and can form very complex shapes.<ref name="p116">'''Halo: Primordium''', ''pages 116, 201, 269''</ref><ref name="halo 4">'''Halo 4'''</ref> As such, hard light is commonly used in the composition of Forerunner structures and ships, either for structural support,<ref name="renegades">''Halo: Renegades'', Chapter ??</ref> aesthetic purposes,<ref name="c242">'''Halo: Cryptum''', ''page 242''</ref> as a covering for mechanical and technological mechanisms, or to form internal divisions and compartments; this allows a Forerunner ship or structure to reconfigure its layout, furnishings or decoration at will.<ref>'''Halo: Cryptum''', ''page 124''</ref> Despite its versatility, hard light construction is susceptible to power failures and as such, the most important supporting structures have to be made of actual matter.

The [[Halo Array|Halo installations]] make use of hard light in their firing mechanisms,<ref>'''Halo: Cryptum''', ''pages 307, 310''</ref> in addition to using hard light as a protective structural reinforcement to stabilize and protect the rings against tidal and gravitational forces from other objects.<ref>'''Halo: Cryptum''', ''page 311''</ref> Although many Forerunner structures project a hard light decorative shell over the structural support elements of the building, almost all buildings seen on the Halo installations or [[Installation 00|the Ark]] lack this covering; the Forerunners did not implement such decoration on the Halos' structures, as they were meant to be purely functional.<ref>'''Halo: Cryptum''', ''page 319''</ref> However, the structures on the Halo rings still employ hard light construction for practical purposes.<ref name="p116"/> Additionally, any structures that possess hard light decor only activated in the presence of Forerunners;<ref name="c242"/> however, due to their status as [[Reclaimer]]s, the presence of humans will also activate hard-light decoration in certain structures, as seen in the [[Menachite portal complex]].<ref>'''Halo: First Strike''', ''page 143''</ref>

Although they can be crafted to be extremely resilient, hard light constructs are not indestructible. Aside from disabling them by deactivating or destroying the power source, hard light constructs can break up upon suffering heavy damage. For example, [[Installation 07]]'s central hard light hub and spokes connecting to the ring were destroyed under the stress of collision with [[Wolf-faced planet|a planet]]. The stress of the hard light structures pressing against the face of the planet caused the spokes to first stretch out, before fragmenting and abruptly turning into curling beams of intense, blue-violet radiation.<ref>'''Halo: Primordium''', ''page 334-335''</ref>

Forerunner [[upgrade seed]]s are able to use hard light to reinforce construction of non-Forerunner origin, such as starship hulls. The ''[[Ace of Spades]]'' received an upgrade seed that reinforced its hull by hard light bonding.<ref name="renegades"/>

===In military technology===

The Forerunners also used hard light technology to create protective personal shields, such as the [[Z-90 Photonic Coalescence Emitter/Aegis]] as it is known by the UNSC, more commonly known as the "hardlight shield," which could be deployed in the battlefield by fighting units like [[Promethean Knight]]s. After encountering such technology in [[2557]], UNSC forces were able to adapt these shields for use by [[SPARTAN Program|Spartan]] supersoldiers.<ref name="Official Site"/> While highly resilient, these shields are not impervious to damage. This is believed to be because of the module's inability to propagate wide-range power generation.<ref name="H4EVGp137"> ```[[Halo 4: The Essential Visual Guide]]`````, page 137``</ref>

[[File:H4-PrometheanKnight-HardlightBlade.jpg|thumb|250px|A closeup of a Promethean Knight's hard-light blade.]]
[[Promethean]] units are also known to incorporate hard light technology into their weaponry and even personal design. For close-quarters combat, [[Promethean Knight]]s utilize [[hardlight blade]]s to dispatch opponents. The [[Z-250 Directed Energy Engagement Weapon|Z-250 Lightrifle]] and [[Z-130 Directed Energy Automatic Weapon|Z-130 Suppressor]] are among the known infantry weapons to utilize hard light projectiles. For offensive purposes, they create solid projectiles that can be fired like conventional bullets or [[plasma]] bolts. Some units have presumably decorative hard light architecture, notably the fins on the back of the [[Knight Battlewagon]].<ref name="Waypoint">[http://www.halowaypoint.com/en-US/Halo4Guide '''Halo Waypoint:''' ''Halo 4 Interactive Guide'']</ref> Hard light was also used as a form of connective mechanism in the limbs of a [[war sphinx]].<ref>'''Halo: Cryptum''', ''pages 93, and 194''</ref> Forerunner [[design seed]]s also made use of hard light. When activated, the rotating pillars of the machine would emit "scaffolding" of hard light that would fabricate a machine or ship using raw materials obtained on-site. During the [[Forerunner-Flood war]], the Forerunners experimented with volatile derivations of hard light, with similar effects to the [[blamite]]; those experiments resulted in a Suppressor variant called "Razor's Edge".<ref>'''[[Halo 5: Guardians]]''', ''Razor's Edge'' description</ref>

To an unknown extent, the [[Covenant]] has made use of hardlight technology in a form of portable energy shielding. At some point, the [[Office of Naval Intelligence]] came into possession of a number of these devices and utilized them for an unknown purpose. The [[Covenant]]'s application of this technology is known to be inferior to that of the [[Prometheans]] of [[Requiem]], however.<ref name="H4EVGp137"/>

[[Ancient humanity]] also known to use hardlight weapon similar to forerunner hardlight weapon.<ref name="c164">'''Halo: Cryptum''', ''page 164''</ref><ref>'''Halo: Cryptum''', ''page 112''</ref>

==Trivia==
*According to the [[Minister of Discovery]] in ''[[Wages of Sin]]'', hard light was one of the several Forerunner technologies the [[Covenant]] never successfully reverse-engineered.<ref name="wages"/> However, the [[San'Shyuum]] [[Prelate]] [[Tem'Bhetek]] sports a hard light shield gauntlet in ''[[Halo: Shadow of Intent]]''.<ref>'''Halo: Shadow of Intent''', ''pages 51, 53, 55'' (Google Play edition)</ref> It is possible that the device was of Forerunner origin, rather than having been manufactured by the Covenant. Alternatively, the Minister of Discovery may not have been informed of the technology incorporated into the Prelate's armor. [[Halo Waypoint]] further claims that the Covenant developed technologies to control and utilize hard light from the analysis of Forerunner technologies.<ref name="universecov">[https://www.halowaypoint.com/en-us/universe/factions/covenant '''Halo Waypoint''': ''Covenant'']</ref>
*There are real-world scientific efforts to manipulate light to behave as a solid surface.<ref>[http://edition.cnn.com/2013/09/26/us/new-lightsaber-molecule/index.html '''CNN''': ''Scientists create light-matter like Darth Vader's lightsaber'']</ref>
