when the electrons move... I'm just ya know guessing

LIght is emitted when electrons accelerate, when particles move faster than the speed of light in a medium (Cerekov radiation) and - most commonly - when electrons make a quantum transition from one energy level to another where the energy difference is large enough.

When matter is enegized to raise electrons to higher energy states and then the electrons return to a lower energy state, the change generates a photon of energy. If the photon energy is between 1.5 Million electron volts and 3.5 Milion electron volts then the photon is perceived as light.

Visible light is emitted from objects when the electrons in that object have absorbed some form of energy and become excited, then give off that energy as light when they move back to their ground state.

The combination of positive and negative energies is one way light is produced. Like the spark from static electricity which can be seen in the dark.

Matter such as a piece of wood will create light when it burns.

at high temperature
light is emmitted when electron jump energy levels (this takes energy)
