Summary
The solar luminosity (L☉) is a unit of radiant flux (power emitted in the form of photons) used to measure the luminosity of stars, galaxies and other celestial objects in terms of the output of the Sun.
1
The International Astronomical Union (IAU) has defined a nominal solar luminosity of 3.828 × 1026 W.

Luminosity is an absolute measure of radiant power, and is usually measured in terms of solar luminosities. The most luminous stars emit several million solar luminosities, while the dim brown dwarfs have luminosities a few millionths that of the Sun.

Summary
Luminosity is an absolute measure of radiant power, and is usually measured in terms of solar luminosities. The most luminous stars emit several million solar luminosities, while the dim brown dwarfs have luminosities a few millionths that of the Sun. Luminosity is an important factor in astronomy, and is often measured in terms of the power of an object.

The Sun is the star at the center of the Solar System. It is a nearly perfect ball of hot plasma,[18][19] heated to incandescence by nuclear fusion reactions in its core. The Sun radiates this energy mainly as light, ultraviolet, and infrared radiation, and is the most important source of energy for life on Earth.
