A '''Hard-Light Bridge''' (simply known as a '''Light Bridge''',) is a semi-translucent solid made from natural sunlight beamed in from the Earth's surface. It can act as a bridge for the player, a shield against turrets and other hazards, or even a wall for more complex puzzles the player encounters later on. Light Bridges first appeared in the [[Portal: The Flash Version MapPack|Flash Version MapPack]] and then in [[Portal: Still Alive]], but were more formally introduced in [[Portal 2]]. The bridges span an infinite length or until stopped by another solid. Although the bridge is made of light, if one portion of the bridge is stopped by a solid object the rest will not continue as a beam of light normally would. Also, portals need to be in center with the bridge if trying to get it to another place, otherwise it won't pass through.

The [[Excursion Funnel]] appears to be closely related to the Hard-Light Bridge, possibly originating as a 3-D version of the 2-D Bridge; or perhaps, the Bridge may have been invented second, by [[Wikipedia:Polarization_(waves)|polarizing]] a Funnel. Both can be sent through portals, defy gravity, and have a similar appearance.

The Hard-Light Bridge as it appears in Portal 2.
“
These bridges are made from natural light that I pump in from the surface. If you rubbed your cheek on one, it would be like standing outside with the sun shining on your face. It would also set your hair on fire, so don't actually do it.
A Hard Light Bridge (simply known as a Light Bridge,) is a semi-translucent solid made from natural sunlight beamed in from the Earth's surface. It can act as a bridge for the player, a shield against turrets and other hazards, or even a wall for more complex puzzles the player encounters later on.
The bridges span an infinite length or until stopped by another solid... Since the bridge is made of light, if one portion of the bridge is stopped by a solid object the rest will not continue as a beam of light normally would.
Hard-Light Bridges can be redirected with portals. Hard Light Bridges emerging from odd portals are orthogonal to them. Also, portals need to be in the center with the bridge if trying to get it to another place, otherwise it won't pass through.
Chell, P-body, and Atlas can adjust placement of the even portals slightly after redirection of Hard-Light Bridges with portals while standing on them in some situations...
Chell, P-body, Atlas can adjust placement of the odd portals after redirection of Hard-Light Bridges with portals while standing on them in most situations...
Hard-Light Bridges can also be covered in Mobility Gels (Repulsion Gel, Propulsion Gel), allowing the player to use the gels in places where it normally would just fall through. Gels placed on Hard-Light Bridges are not permanent and disappear the moment the bridge dissipates or moves to a different location or when Atlas and P-body die.
A Hard Light Bridge will prevent the Sentry Turret from even detecting the enemy.
The bridges in Portal: Still Alive are mostly functionally identical to the ones in Portal 2, but notably cannot be extended through portals (and do not block turrets).
“Nope, still can't see!” This page would benefit from the addition of one or more images. Please add a suitable image, then remove this notice.The specific instructions are: "Needed: screenshots of it being used in-game redirected through portals, or used as shield, or as platform for gels"
