In the case of LED lighting, lumens are the unit of measurement of the brightness of the light. The concept of lumens is different from watts. While watt measures the amount of energy consumption, lumens measure the brightness of the light.

12-inch red traffic lights, for example, in the United States could have been used long life, low light efficiency of 140 - watt incandescent lamp as light source, it produces 2000 lumens of white light. After the red filter, light loss 90%, only 200 lumens of red light. And in the...
When it comes to lighting, efficiency is defined as the light output per unit power. Thus, in the metric system, it is measured in lumens (lm) per watt (W). Recently some LED manufactures introduced LEDs with promised efficiencies hitting the 150 lm/W mark. In comparison, incandescent ...
For instance, an incandescent bulb would consume 60 watts of electricity to light up the same room for which an LED bulb would only take 10 watts. Also see:Hanging lights simplified: Dimensions, drawings & designs (Buy now!) Advantages of LED lights ...
