The phrase 'brightness of light' is correct and can be used in written English.
You can use it to describe something that is giving off a lot of light or to describe a particular kind of light. For example: "The woman squinted at the brightness of light coming from the chandelier."
In this algorithm attractiveness depends on brightness of light and a bright firefly feels more attraction for the brighter one.
When she was an old lady, she wrote that her first memory was of light; the brightness of light, of light all around.
So the researchers built a model that considers all of your pacemaker cells, how sensitive you are to light, the brightness of light, multiple time zones and people's slightly off kilter internal clocks.
In 1998, the two teams of researchers published results based on observations of the brightness of light from similar supernovas, enabling them to work out how far away they were and how much farther they were than when the star initially exploded.
The quantity of light pollution from a given area depends on the number and brightness of light sources on the ground, the fraction of light that escapes above the horizontal, the reflectivity of surfaces near the light sources (e.g., roads, pavements, walls, windows), and the prevailing atmospheric conditions.
To determine how the trees would appear to a moa, the team measured the wavelength and brightness of light reflected by the leaves.
The brightness and durability of light-emitting diodes (LEDs) make them ideal for displays, and semiconductor laser diodes (LDs) have been used in numerous device applications from optical communications systems to compact disk (CD) players.
As Williams points out, if a malicious app accomplished the same feat, it could extort money from the user by "randomly changing the brightness or color of lights until they pay".
The control strategy presented in this paper includes two parts: a new multivariate extremum seeking control method with Newton algorithm is developed to minimize the light-energy consumption by separately manipulating the brightness of multiple lighting sources, and a proportion-integration-differentiation control approach is adopted to realize the desired lighting level.
