Photons are small bundles of energy that make up light. Scientists consider photons to be elementary particles which are a quantum or measurement of light.
Light is pure energy. Apparently in packets called photons. Since it (light) has no mass, it always travels at the "speed of light" (which varies depending on the medium its traveling through). It's motion is the only measurement of its energy content.
ray or laser
The w means watt. It is a unit of measurement that quantifies the energy given off by the globe when it is switched on.
The science of measurement of visible light in terms of its perceived brightness to human vision (optics).The measurement of the flux or intensity of an astronomical object's electromagnetic radiation (astronomy).
the measurement of energy mass speed of light
There is no "measurement of light". The units used depend on what you want to measure: its speed, frequency, wavelength, energy per photon, etc.
A spectrometer measures the wavelength, wave number, and photon energy of light. They are measurements of the type and energy levels of light.

As for any energy, Joules are the unit of measurement

No. A light-year is a measurement. A light year is a distance measurement based on how far light travels in a year.
