Power relates to light bulbs through the equation power = work/time, where power is the rate at which electrical energy is converted into light energy. Brighter bulbs have higher wattages because they can either heat a larger tungsten filament to the same temperature or heat the same filament to a higher temperature, increasing light output. Incandescent bulbs require continuous energy to maintain filament temperature, resulting in higher power consumption. The brightness of a bulb is directly linked to its power consumption, as more power results in more light being radiated. Understanding this relationship clarifies why certain wattages produce brighter light.
