Sure, I'll add some light, if you can find me the spells aside from the ones already listed.

Common Light magicks:
Light, Ellight, Shine, Divine, Purge, Aura, Luce, Thani, Rexaura.

Legendary Light magicks:
[b]Ivaldi[/b] - meaning [i]Glorious Light[/i], it is one of the Sacred Twin Weapons, it's counterpart being the Saint's Staff [i]Latona[/i]. Does increased damage to monsters.
[b]Aureola [/b]- meaning [i]Pinnacle of Light[/i], it is one of the eight Legendary Weapons of Elibe. When cast, the heavens will open up and shine a single beam of light upon a selected enemy target, momentarily petrifying him/her in his/her tracks. A sparkle will then cascade down this beam of light, causing the beam of light to dissipate and combust, engulfing the selected enemy target in the process.
[b]Book of Naga[/b] - Bestowed unto the Crusader Heim by the Divine Dragon Naga it is powerful magic only weildable by one possessing Naga holy blood.
[b]Creiddylad[/b] - a special Light Magic tome wielded exclusively by Sephiran, the Creiddylad tome will surround an enemy target with four divine orbs when cast, which swirl around then before honing in and combusting.
[b]Valaura[/b] - a fragile tome and the only one of it's kind. Valaura is the only documented Corrupted Light Tome. It was drastically altered by a mage named Valtome for his own purposes. It is capable of inflicting the poison upon opponents and generating a gargantuan orb of pestilential light which draws foes into it before combusting. It is thought that before this tome was altered it was an ordinary copy of Rexaura.

I'd imagine most of the legendary tomes won't make it in given there relative rarity, specific purpose or just plain over poweredness but I thought I'd list them anyways. For the record neither Dark or Light magic are inherently evil or good. They utilize elements just like fire and wind. Many priesthoods and churches in Fire Emblem have a predisposition to using Light magic leading people to think that it is somehow divine.
