American Heritage® Dictionary of the English Language, Fourth Edition
- n. The condition or quality of being luminous.
- n. Something luminous.
- n. The ratio of luminous flux at a specific wavelength to the radiant flux at the same wavelength. Also called luminosity factor.
Century Dictionary and Cyclopedia
- n. The quality of being luminous or bright; luminousness; the radiation or reflection of light.
- n. Specifically, the intensity of light in a color, measured photometrically. That is to say, a standard light has its intensity, or vis viva, altered until it produces the impression of being equally bright with the color whose luminosity is to be determined; and the measure of the vis viva of the altered light relatively to its standard intensity is then taken as the luminosity of the color in question.
- n. In botany, phosphorescence.
- n. uncountable the state of being luminous, or a luminous object; brilliance or radiance
- n. physics the ratio of luminous flux to radiant flux at the same wavelength; the luminosity factor
- n. astronomy the rate at which a star radiates energy in all directions
GNU Webster's 1913

“The word luminosity describes the nature of celestial light, and the music of composer James Whitbourn is a celebration of that light: peaceful, radiant and clear.”
“The rods detect motion — changes in luminosity — better than do the cones.”
“Polaris fluctuates in its short-term luminosity as well.”
“25In their reply, Pettersson and Kirsch stressed the fact that the ratio in luminosity between alpha and H-particles (protons) does not permit such a mistake as Bates and Rogers attributed to them. 38 On July 19, even before the articles were published, Rutherford sent his results to Pettersson. 39 In a friendly and grateful response on July 27, Pettersson tried to reconcile and explain the discrepancies.”

“How could the observer call the luminosity thus produced?”
“The orchestration here is very thick, but not at all heavy or cluttered; in fact, it has a uniquely peculiar luminosity, which is animated by its actually relatively thin, more truly contrapuntal texture.”
“Buddhism is less tongue-tied than this: reality has all the qualities of a Buddha, wakefulness, intelligence, compassion — attributes which are often called "luminosity" to distinguish it from sheer lack of existence.”
“The third turning teachings are often called "luminosity" to distinguish them from the second turning teachings on emptiness, though they are said not to contradict this view, but to complement it.”
“Diaz has turned at long last to Photoshop and the result is that his illustrations, rather than becoming mechanical or hackneyed, have taken on a kind of luminosity never achieved before.”

I can't say exactly what makes these words sound so harmonious...the finely balanced distribution of consonants and vowels? the lack of harsh sounds? the regal elegance of Latin roots? anyway...
