(particle physics) The quantum of light and other electromagnetic energy, regarded as a discrete particle having zero rest mass, no electric charge, and an indefinitely long lifetime. It is a gauge boson.

Editorial note
The difference is, that the electro magnetic field is a fundamental aspect of nature, while the deformation field only describes deformations of a given crystal and therefore photons are fundamental particles, while phonons are quasi particles.

It also helps you deal with the idea of 'how do different photons carry different amounts of energy?'.

We lose a few photons during the conversion process and that drops us down to about 2.0.
There's a big difference between absorbing reflected ambient light and having photons pumped into your retina.
This gives the opportunity for green photons to reflect their way down to the bottom leaves for a more distributed growth.
The signals are going to be so weak by the time the photons get here they will be indistinguishable from the CMB.
And in addition to being spread apart, they'd need to be pretty huge in order to capture enough photons from the target.
They don't interact at all with electromagnetism so they'll give off no photons or radiation to be detected from that at least.
You can achieve 200% wall-plug efficiency, but only if you're converting picowatts of electricity into picowatts of photons in a hot LED.
There's always going to be a limit to how well any macroscopic analogy can possibly describe what's going on with photons and light, but some metaphors work better than others.
From what we do know it's affected by gravity and doesn't interact with normal matter or photons.
Quote examples
On a related note, QED does provide a lot of context for what "light"(photons) is(are).
We have a "recycling cavity" behind the phosphor plates that reflects "backward" emitting photons.
Context: "The company has developed a wavelength conversion system that uses phosphorous to convert blue photons, which are the most efficient type of photon, into any other color photon."
Proper noun examples
Photons don't really have a height, so they don't really have an amplitude.
Photons aren't really spinning cannonballs.
