The unit of measurement is the "light year".
A candela is a unit of measurement for light sources and light emissions. Light beams projects different color at different wavelengths, and a candela is used to measure the intensity of the light.

You cannot 'measure' light. However, there is the light-year, a measurement of the distance light can travel in one year. there are many. Lumens, cadlepower, foot candles and candelas. There are probably a few more.

The unit of metric measurement most useful for light microscopy is the micrometer (μm), which is one-thousandth of a millimeter. This unit allows for precise measurements of objects that can be visualized under a light microscope.

usually lights are measured in lumens
False. Decibel is a unit of measurement used to express the intensity of sound, not pollution. It measures the level of sound pressure. Pollution is typically measured in terms of air quality indices, concentration of pollutants, or other specific measurements depending on the type of pollution being measured.
