Luminous flux (in lumens) is a measure of the total amount of light a lamp puts out. Wattage is the amount of watt a bulb uses in 1 hour. We've long identified bulbs by their wattage, but that is actually a measure of electricity, not the brightness of a bulb. The amount of light a bulb generates is measured in lumens. An incandescent 60-watt bulb, for example, gives off 750 lumens of light and LED bulbs can deliver the same amount of light using as little as 9 Watt! The amount of Lumen divided by the wattage will show you which lamps are most energy efficient.
