Watts vs Lumens A bulb's wattage tells us how much energy it uses, rather than the amount of light it generates (lumens). Lumens (lm) are a measure of the total output of visible light from a lamp or light source. The higher the lumen the “brighter” the lamp will appear. To make comparing bulbs easy, it's best to look for the light output (lumen).
