A quantum of energy is the most basic unit of energy.
According to the quantum theory put forward by German physicist Max Planck in 1900, energy exists as discrete particles called quanta. The energy of a quantum E is given by:
E = hf
where h is the Planck constant (h = 6.6 x 10-34)
and f is the frequency of the radiation.
A quantized packet of light is a photon. Is it NOT a lumen, which is a measure of the power of light perceived by the human eye.
I believe its called photon

Photon
True, a photon is a quantum of energy, E=hf.
Light waves have electromagnetic energy. Could be considered as quantum of energy with an expression E = h v. v is the frequency of light wave. h - Planck's constant. E - the energy possessed by the quantum. This quantum is also known as photon
The smallest quantum of energy is E=hc/w = 2E-25/w where w is the wavelength.
Light of is made up of a finite number of photons, or light quanta. The energy of each photon is proportional to the frequency of the light, and hence inversely proportional to the wavelength of the light. Red light has a longer wavelength than blue light, so the quantum of red light has less energy than the quantum of blue light.
Violet light has greater energy because it has higher frequency than yellow light
Quantum
In the universe energy, matter and go as per quantum. Energy is released in quantum of photon. Electron has a quantum mass. Proton has quantum mass. Both has a quantum charge. Neutron has a quantum mass. Speed of light is a quantum. Big bang is a quantum event essentially occurring at particular mass. It takes a quantum energy for shifting of electrons from one shell to other. In photo-luminescence light energy is released in quantum.
