The unit of measurement ‘lumen’ (lm) indicates how much light (luminous flux) a luminous source emits per defined period of time

The higher the ‘lumen value’ (luminous flux, abbreviated to lm), the more light a lamp emits in all directions.

Unlike the unit lux (= illuminance), the object being illuminated is not taken into account here.

Why is this important?

• The lumen rating helps you to better assess the brightness of a work light.

By the way:

With conventional incandescent bulbs, light output was still dependent on power consumption in watts.
This has now changed fundamentally, as HAZET’s LED technology minimises power consumption and maximises the lumen output.
