Question: are watts and lumens the same?
Answer: The wattage of a light bulb refers to the power consumed to burn the bulb. Lumens refer to the brightness of the bulb. We're used to buying light bulbs based on their wattage, and we know a 100-light bulb is brighter than a 60-watt bulb because it uses more power to produce light and heat. ... Lumens measure light output.
