There is an error in the calculation of the brightness in mode "H-Resolution Mode2".
In this mode the value must be divided by two again to get the correct brightness.

Reproducibility:
Switch between "H-Resolution Mode" and "H-Resolution Mode2" to see that the value is suddenly halved.

H-reslution mode : Illuminance per 1 count ( lx / count ) = 1 / 1.2 *( 69 / X )
H-reslution mode2 : Illuminance per 1 count ( lx / count ) = 1 / 1.2 *( 69 / X ) / 2
