A 100-watt bulb is a type of incandescent light bulb that consumes 100 watts of electrical power to produce light. It typically emits around 1600 lumens, providing bright illumination suitable for various settings, such as homes and offices. These bulbs are often used in fixtures where strong lighting is needed, like living rooms or kitchens. In recent years, LED bulbs have become popular alternatives to traditional 100-watt incandescent bulbs. They use significantly less energy, often producing the same amount of light with only 15-20 watts. This shift helps reduce electricity costs and environmental impact while maintaining brightness.
