Description: Extinguishes wandlight. It the counter-charm for the Wand-Lighting Charm, Lumos.
Seen/Mentioned: In 1994, Harry Potter and Hermione Granger used this spell to turn off their wand-lights in the Shrieking Shack. Used in 1998 when Harry was in the passage beneath the Whomping Willow which leads to the Shrieking Shack. Lumos's power can be arranged so that a powerful wizard can make the charm illuminate intensely or to the wizards liking by loudness of incantation. For example "LUMOS!!!" would be powerful and "lumos" would be weaker. Also used by Harry Potter in 1998 to turn off the light so he could hide the Marauder's Map from Severus Snape.
Etymology: Latin nox, meaning "night".
