brightness is measured in lumen's in new measurements, or candle power in old.
to measure it, you need to get a photometer
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.

Anything that is not the measure of intrinsic brightness of a celestial object.
To adjust the lighting in your room using dimmer switches for lamps, simply turn the switch up or down to increase or decrease the brightness of the light. This allows you to create the desired ambiance and level of brightness in the room.
The standard measure used to determine the brightness of a light bulb is called lumens.
A photometer is a device used to measure surface brightness. It detects and quantifies the amount of light emitted by a surface, typically in astronomy to measure the brightness of stars and galaxies.
The brightness of a star.
When choosing 3-way table lamps for your home, consider the lamp's design, size, and brightness levels. Look for a style that complements your decor, a size that fits your space, and multiple brightness settings for versatility.
Bulbs are typically measured in watts to indicate power consumption, and in lumens to indicate brightness. Wattage is a measure of the amount of power a bulb uses, while lumens measure the amount of visible light the bulb emits. It is important to consider both measurements when choosing a bulb to ensure it meets your lighting needs.
To accurately measure the brightness of a fluorescent bulb, you can use a light meter or a lux meter. These devices measure the amount of light emitted by the bulb in units called lux. Place the meter close to the bulb and take a reading to determine its brightness.
