on light bulb packages, brightness means luminous flux, while in other contexts it means luminance.

Alternative symbols sometimes seen: W for luminous energy.

/kænˈdiːlə/; symbol: cd) is the base unit of luminous intensity in the International System of Units (SI); that is, luminous power per unit solid angle emitted.

searches for highly luminous stars are inevitably biased towards detecting systems with multiple more normal stars combining to appear luminous.

It is the ratio of luminous flux to power, measured in lumens per watt.

Luminance is a photometric measure of the luminous intensity per unit area of light travelling in a given direction.

time and luminous intensity respectively, not the symbols for the units litre, tesla and joule.

A hot, luminous main-sequence star may also be referred.

In photometry, luminous intensity is a measure of the wavelength-weighted power emitted by a light source in a particular direction per unit solid angle.

luminous red novae, pl.

The lux (symbol: lx) is the SI derived unit of illuminance, measuring luminous flux per unit area.

A luminous red nova (abbr.

W2246−0526 for short) is an extremely luminous infrared galaxy (ELIRG) which, in 2015, was announced as the most luminous known galaxy in the Universe.

SI derived unit of luminous flux, a measure of the total quantity of visible light emitted by a source per unit of time.

absolute magni- tude (MV) Supergiants are among the most massive and most luminous stars.

Stars still more luminous than giants are referred to as supergiants and hypergiants.
