Apparent magnitude.
The brightness level perceived by the unaided human eye is referred to as "apparent magnitude." This scale measures the brightness of celestial objects as seen from Earth, with lower numbers indicating brighter objects. For example, a star with a magnitude of 1 is brighter than one with a magnitude of 6, which is near the limit of visibility for the average human eye in dark conditions.
A star's brightness as viewed by the unaided eye is measured using a scale called apparent magnitude. This scale quantifies how bright a star appears from Earth, with lower numbers indicating brighter stars. For example, a star with an apparent magnitude of 1 is brighter than one with a magnitude of 6, which is at the limit of what the average human eye can see under ideal conditions. Factors influencing a star's apparent brightness include its intrinsic luminosity, distance from Earth, and any interstellar material that may dim its light.
A star's brightness as viewed by the unaided eye is measured using its apparent magnitude, which quantifies how bright a star appears from Earth. The scale is logarithmic, meaning a difference of 5 magnitudes corresponds to a brightness factor of 100. Stars with an apparent magnitude of around 6 or lower can typically be seen without telescopes, while brighter stars have lower magnitude values. For example, the brightest stars in the night sky, like Sirius, have apparent magnitudes of around -1.46.

Brightness settings should be in the Pop-it menu under "Global Settings."
The brightness level of a 5 watt LED bulb is equivalent to a 40 watt incandescent bulb.
The brightness level of a 25 watt LED bulb is equivalent to that of a 100 watt incandescent bulb.
The conversion factor from lux to nits is 1 lux 1 nit. This means that the brightness level of a light source in lux is equivalent to the brightness level in nits. To determine the brightness level of a light source, you can measure the illuminance in lux using a light meter and then convert it to nits by applying the conversion factor. This allows for a standardized comparison of the brightness levels of different light sources.
It depends on what the sentence is: The brightness of the sun is blinding. The word brightness would be an adjective.
Pixel amplitude refers to the maximum brightness level that a pixel can display in a digital image. It is a measure of the intensity of light that a pixel emits, often represented by a numerical value within a certain range, such as 0-255 for an 8-bit image. This value determines the color and brightness of the pixel when viewed on a screen or printed on paper.
