Lumens vs. watts
Watts (W) indicate electrical power consumption, while lumens (lm) indicate light output. When comparing LED lights, lumens are therefore more useful than wattage alone.
LUMEN · lm
What are lumens (lm)?
Lumens, abbreviated lm, indicate how much visible light a light source emits. The more lumens a light emits, the greater its total light output.

Lumens, watts and lux – what is the difference?
Lumens, abbreviated lm, indicate how much visible light a light source emits. The more lumens a light emits, the greater its total light output.
What does lm/W mean?
Lumens per watt, lm/W, indicate luminous efficacy. A higher lm/W means the light produces more light output for each watt it consumes and may therefore be more energy-efficient.
Lumens vs. lux
Lumens measure the total light output of a light source, while lux measure the light falling on a given surface. This is why the right lighting for a space cannot be determined from lumens alone.
