The Ball of Light Transformation is a peculiar form of Voluntary Shapeshifting, where a character becomes not another creature but a flying orb, mote, speck, flame or tiny star made of light. Size, color and brightness can vary.
Such a form is often invulnerable, light being intangible, or at the very least very hard to hit thanks to its small size and mobility. Some can even goes through walls, or slip through tiny spaces. Although many will just use this form as an alternate means of Flight.
Contrasting with this transformation as a standard power, it can also be a one-time event when a character is metamorphosed, resurrected, ascended to a higher plane of existence or other life-changing event.
The popularity of this trope in film or live-action TV can be linked to it being a very easy special effect.
- Eto Rangers: The Jyarei Monsters, the Jyarei Elite and even Jyarei Queen Nyanma herself are all capable of turning into balls of light. For the Monsters and the Elite, they do this to invade the Novel Worlds; in Nyanma's case, she uses it when she goes to Mugen on certain occasions.

Lilliandil: If [my beauty] is a distraction, I can change form.
- Glinda the good witch turns into a pinkish orb to fly around in The Wizard of Oz.

- In Stargate SG-1 and the rest of the Stargate-verse, people who Ascend to a Higher Plane of Existence take the form not of a ball of light, but of a luminous blob with waving tendrils, sometimes dubbed a "light jellyfish".

- This is the true form of the Organians in the Star Trek: The Original Series episode "Errand of Mercy". The amiable old men turn into blindingly bright light at the end of the episode — their humanoid appearance was simply A Form You Are Comfortable With.
- In the Series Fauxnale for Mystery Science Theater 3000, as the Satellite of Love crew approaches the edge of the universe, they become balls of light corresponding to the main colors of the characters (Mike=Blue, Crow=Yellow, Servo=Red, Cambot=White, Gypsy=Purple). Of course, when the series was Uncancelled, they reverted back to their regular forms.

- In BIONICLE, Umbra has this ability and uses it offensively.
