Light amplification visor



The light amplification visor is a powerup that appears as a pair of gray goggles with blinking red lenses. Picking one up will show everything at full brightness for 120 seconds. When 5 seconds remain, the display will begin blinking back to its original light level, signaling the end of the visor's effects.

Light amplification can also be activated with the cheat code idbeholdl.

Light amplification visors are the rarest of Doom's powerups, as they undo the various lighting effects that are an integral part of the game's atmosphere (although in Doom II, three can be found in a single level: the Refueling Base).

Light amplification visors are included in the items percentage displayed at the end of each level.
