The wattage of a light fixture directly affects the amount of energy it uses. Wattage refers to the amount of electrical power the light fixture consumes, or the rate at which it uses energy. The higher the wattage, the more energy the light fixture consumes, and the higher the electricity bill. For instance, a 100-watt bulb uses more energy than a 40-watt bulb. Therefore, choosing a low-wattage light fixture or bulb can help reduce energy consumption and lower your electricity bills.
