The number of lux depends on the distance from the lamp.


At a distance of 10 cm (very close), this is as follows:


Position             Lux


5                     10000


4                       6400


3                       4000


2                       2200


1                       1000


 


The further away you sit from the lamp, the less light intensity. 


So on setting 1 or 2 it is under 2500 lux but at a distance of 10cm, that is very close.




For example:


We have now also done a measurement on setting 5 and measured the distance to where it drops below 2500 lux, which is from 25 cm. Probably more pragmatic, so on setting 5 from 25 cm you are under the 2500 Lux.
