If you're writing for broad audience, you will be accepted if you're skimming the details and not going in-depth. If you focus on a specific audience, you might ride the wave of the success of [The Martian](https://en.wikipedia.org/wiki/The_Martian_%28Weir_novel%29) if you go really in-depth. Instead of "power of light", gain mastery of electromagnetic waves. Radio, laser, X-ray, microwave (+radar), infrared, ultraviolet, matters of light pressure, albedo, polarization, even quantum entanglement - that's all your oyster to open, discover ways the character can exploit the understanding of common "light wave" and apply it to their advantage. Personally, I don't see how it could be derived from levitation though.
