The higher the "lumen value" (luminous flux, abbreviation Lm), the more light a lamp distributes in all directions.

In contrast to the unit lux (=illuminance), the illuminated object is not taken into account.
With incandescent lamps, the light output was still dependent on the power consumption in watts.
This has now fundamentally changed, because the HAZET LED technology minimises power consumption and maximises the lumen value.
