A lux meter is a device that measures surface brightness.

Both relate to brightness; both are measured in the same units; both are used for astronomical objects such as stars or galaxies.
An asteroid's brightness may change as it rotates because different surface features reflect varying amounts of sunlight towards Earth. As the asteroid rotates, different surface areas are illuminated, causing the brightness to fluctuate in a repeating pattern. This variation in brightness can provide valuable information about the asteroid's shape, surface composition, and rotation period.
To change the brightness on your Altec device, you can usually do so in the settings menu. Look for a display or brightness option where you can adjust the level to your preference. Some devices may have a quick shortcut in the notification panel for easier access to adjust brightness.
An astrometer is a device designed to measure the brightness, relation, or apparent magnitude of stars.
A device by which flatness or roughness of a glass surface is measured.
Surface tension is typically measured in a scientific experiment using a device called a tensiometer. This device applies a force to the surface of a liquid and measures the resulting deformation, allowing researchers to calculate the surface tension of the liquid.
An apparent brightness is the brightness of a star as measured by an observer.
The brightness of light produced by a source can be measured using a device called a photometer or lux meter. These tools measure the illuminance of light in lux, which is a unit of measurement for the amount of light that reaches a surface. By placing the photometer at the location where the light is being emitted, you can quantify the brightness level.
The unit of brightness is typically measured in candelas per square meter (cd/m²) or nits. These units quantify the amount of light emitted or reflected by a surface.

The measure of a star's brightness is its magnitude. A star's brightness as it appears from Earth is called its Apparent Magnitude.Star's brightness is measured by there magnitude.

Brightness of light sources is measured using a unit called lumens. Lumens indicate the total amount of visible light emitted by a source, with higher lumens corresponding to greater brightness.
To change the brightness on a TruTech device, navigate to the settings menu, usually accessible by pressing the "Menu" button on the remote or the device itself. Look for a "Display" or "Brightness" option within the settings. Adjust the brightness level using the provided slider or options and save your changes. If your device has a quick access feature, you might be able to adjust brightness directly from there as well.
The relationship between brightness and perception in lighting, measured in lumens, demonstrates a logarithmic scale because our perception of brightness increases more slowly as the actual brightness increases. This means that doubling the lumens doesn't result in a perceived doubling of brightness.
