Lumos spellbook

"The L-l-Lumos s-s-spell b-b-book is located on the other side of this crawlspace. Find and the s-s-spell will be yours."

- Quirinus Quirrell teaching Defence Against the Dark Arts

The Lumos spellbook is a book containing information on, and instructions of how to perform, Lumos. It was hidden in the bowels of Hogwarts Castle and protected by several simple obstacles, which Professor Quirinus Quirrell used to provide a challenge to his students learning the Wand Lighting Spell in his classes.
