Then it's using the wrong units as EV (Exposure Value) has to take account of shutter speed and aperture. In fact that's all it is, the level of exposure. It does not take into account the amount of light.

At ISO 100 the figures are the same.
In the light meter's defence, it probably does state that all EV readings are for ISO 100 in the instructions but technically, using EV to represent light levels is not correct.
It's like measuring the length of a brick wall in kilogrammes. Only valid if you know the cross sectional area and the density!
