Photokinesis

Photokinesis was the ability to generate, project and manipulate light.

The creation of bright and colorful lights would usually occur as a result of a spell but light on itself could be made through magic.

Examples

 * When Buffy Summers, Xander Harris, Willow Rosenberg and Oz were trapped in the Alpha Delta frat house party during Halloween under the influence of the demon Gachnar, Willow insisted on using magic to locate other party-goers and find a way out despite her friends objections at Willow wasn't experienced enough. Willow create a small, floating fixture to light that resembled a firefly. This firefly then multiplied and attacked her.
 * When Willow and Tara Maclay searched the ruins of Sunnydale High to find Riley Finn who was currently residing in there, they found it too dark so Willow lit up the room with an incantation followed by the breaking of a potion. According to Tara, the spell would only cause a "teeny tinker bell light" though Willow claimed she "tinkered with the tinker bell" to increase the light generated.
 * Tara magically created a small orb of light to find Xander and Willow after she and Anya Jenkins were separated from the other two when they were attacked by the Hellions. This ball successfully located Xander and Willow while they were lost in the woods and then tracked them back to Tara and Anya.
 * When Cordelia Chase became part-demon, she gained some form of photokinesis as a result. She intentally lit up the whole Hyperion Hotel when it was infested by Sluks, restoring the building's power and destroying every sluk. She later used it on Connor when he was attacking her, causing the blade of his knife to disintegrate and and convincing him to stop. She also allegedly used this power as a night light.
