Most people think that a watt is what measures the brightness of a bulb. This actually isn’t the case. Watts measure how much energy the bulb consumes. A lumen is what is actually used to measure the brightness of a bulb.
The more lumens a bulb has, the brighter it will be. Typically this coincides with the amount of energy (watts). See the chart below:
Now that there are so many different types of bulbs to choose from (incandescent, LED, CFL, etc), using watts as a measurement of brightness isn’t always a smart method. Bulbs these days consume energy (watts) in different ways, so using lumens to determine the brightness is a sure way to make sure you’re getting the level of light intensity that you need.
