What does lumen mean?

Lumens are more accurate way of measuring the amount of light a particular bulb is putting out, because lumens are a direct measurement of light output. Wattage, even though it is what people have become accustomed to seeing on packaging and measuring how much light they are seeing, it is not really an accurate way to measure light output. Just because a light bulb uses a particular amount of energy to run, does not mean that it directly correlates with the amount of light that is put out. With a variety of energy efficient CFLs, LEDs and Halogen lamps coming onto the market on a regular basis that do not use nearly the same amount of energy as incandescent bulbs it makes sense for people to move away from thinking about wattage when they purchase a bulb and start thinking about lumens.
