A 100-watt incandescent bulb gives off 1,600 lumens. Watts measure the electrical energy required to light a bulb, while lumens are a measure of the brightness of the light produced.
Know MoreEnergy-saving bulbs such as compact fluorescent lamps and LED bulbs that produce an equivalent lumens as the 100-watt incandescent bulb use only 24 to 25 watts of energy. These bulbs also last longer, allowing users to save more on energy costs. To help consumers buy CFLs and LED bulbs, the Federal Trade Commission and manufacturers have worked together to create new labels for these bulbs. Indicated in the labels are the bulbs' brightness in lumens, life expectancy, watts used and light appearance. This makes it easy for consumers to buy energy-saving replacement bulbs for their old incandescent bulbs.
Learn more about MeasurementsOne hundred yards is the equivalent of 91.44 meters. Since 1 yard is the equivalent of approximately 0.914 meters, multiplying the 100 yards by 0.914 meters per yard yields the number of meters. Since 100 centimeters equals 1 meter, the measurement is also equal to 9,144 centimeters.
Full Answer >The equivalent of 100 yards, which is the length of a football field from goal line to goal line, is about 300 feet. One yard is equal to 3 feet. Given that 36 inches make up a yard, 100 yards is composed of 3,600 inches.
Full Answer >100 meters is equal to 109.36 yards. In formulaic terms, 1 meter is equal to 10,000/9,144 yards, and 100 meters is equal to 100*(10,000/9,144) yards. Both numerical calculations extend to many decimal places.
Full Answer >Lumens per watt is a measurement that dictates how much light is produced for each watt of electricity used. The more lumens per watt, the more light is produced without adding extra expense or electricity usage. This measurement is used to determine overall brightness of light bulbs.
