The standard measure used to determine the brightness of a light bulb is called lumens.
The standard unit for measuring the brightness of light is called the candela (cd), not the "kwe" unit.
amplitude will determine the brightness in light or the loudness in sound.
To determine the total brightness of multiple light sources when their lumens are additive, you simply add up the lumens of each individual light source. This will give you the total brightness of all the light sources combined.
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.

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.
You would have to measure the lumen output before and after to determine is there was a change. There are light meters that can do this. You need to be aware of any background or ambient light during such measurements.

The intrinsic brightness of a star is called its absolute magnitude. This is a measure of how bright a star would appear if it were located at a standard distance of 10 parsecs (32.6 light-years) from Earth.

Lux and nits are both units of measurement for brightness, but they measure different aspects of light. Lux measures the amount of light that falls on a surface, while nits measure the brightness of a light source itself. In simpler terms, lux measures how bright the light is on a surface, while nits measure how bright the light source itself is.
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.
You can use a light meter to measure the brightness of a light bulb. This device measures the illuminance or luminance level produced by the light bulb and gives you a numerical value for its brightness in units such as lux or foot-candles.
Lumens measure the total amount of light emitted by a source, candela measures the intensity of light in a specific direction, and lux measures the amount of light that falls on a surface. Lumens indicate overall brightness, candela measures brightness in a specific direction, and lux measures brightness on a surface.
