|Wand Lighting Spell|
Lumos (LOO-mos or LOO-mohs)
Causes the tip of the wand to glow
The Wand-Lighting Charm (Lumos) is a charm that causes the tip of the caster's wand to emit a warm glow. Its counter-spell is the Wand-Extinguishing Charm. It is taught in first year Defence Against the Dark Arts classes and is detailed in both the Standard Book of Spells, Grade 2  and the Lumos spellbook.
Lumos is simultaneously one of the simplest and most useful spells of all, rivalled only in its pragmatism by Flipendo. Not only can the light produced from produced illuminate dark areas like a lantern (which is in itself very useful) but is is the only known spell effective at repelling spectral foes, such as Gytrashes and malevolent spirits.

Behind the scenes
- It is possible this charm is not affected by The Trace, perhaps because it is incredibly simple and looks like torch light, so this spell could be used outside Hogwarts.
- In the opening of The Wizarding World of Harry Potter, Daniel Radcliffe, Michael Gambon, Bonnie Wright, Rupert Grint and James and Oliver Phelps tried to use Lumos to illuminate Hogwarts Castle. However, they did not succeed and they tried a stronger version of this spell, Lumos Maxima.
- In the film adaptation of Harry Potter and the Prisoner of Azkaban, if one listens closely, the Lumos charm appears to make a very soft humming sound.
- Lumos is perhaps the most consistently portrayed spell in the movies and games in terms of appearance; almost always appearing as a bright blue (or yellow) light with faint pulses emanating slowly from the wand tip, occasionally precipitating smoke.
- Other versions of the spell were used in the movies and games:
- Lumos Solem was used by Hermione Granger in Harry Potter and the Philosopher's Stone, creating a beam of sunlight.
- Lumos Maxima was performed by Harry Potter at the Dursleys' house in Harry Potter and the Prisoner of Azkaban, and was also used in the Horcrux cave in Harry Potter and the Half-Blood Prince by Albus Dumbledore and Harry Potter. It creates an extremely large ball of light at the end of the wand, which can even be cast off to hover and light a greater area.
- In the video game adaptation of Harry Potter and the Prisoner of Azkaban, Ron Weasley has a version called Lumos Duo, which shines an intense ray of light upon an object or creature.
- In the PS2, XBox, Gamecube, and PC/MAC versions of the video game adaptation of Harry Potter and the Philosopher's Stone, Lumos can also be cast on gargoyles, causing them to summon platforms of light tangible enough for a person to stand on. The is probably not an inherent spell effect on Lumos but the result of a spell (or series of spells) cast over those gargoyles to make them react in such a way at the use of the Lumos spell.
