If the three light bulbs described above produce 900 lumens each, their luminous efficacy values are the following: The concept of luminous efficacy describes how well a lamp converts watts into lumens, similar to the gas mileage (MPG) of a car. However, this comes from the old practice of describing brightness with watts, when the correct unit is the lumen. For example, the lumen output is roughly the same for a 60W incandescent bulb, a 15W compact fluorescent light, and a 9W LED bulb.Ī common misconception about LED lighting is that you end up with a darker room due to the lower wattage. ![]() The conversion efficacy from watts to lumens changes depending on the lighting technology.
