To accurately measure the brightness and efficiency of fluorescent bulbs, one can use a device called a light meter to measure the amount of light emitted by the bulb in lumens. The efficiency of the bulb can be calculated by dividing the number of lumens produced by the amount of power consumed in watts. This will give you a measure of how effectively the bulb is converting electricity into light.

Light years are a unit of distance used to measure vast distances in space. To measure light years, scientists use tools like telescopes and spectrographs to observe the light emitted by stars and galaxies. By analyzing the light's properties, such as its brightness and spectrum, scientists can calculate the distance to these celestial objects in terms of light years.
LED light bulbs do not get as hot as traditional incandescent bulbs when in use because they are more energy-efficient and produce less heat.
