As a camera/light meter should try to reproduce the human eyes response I'd think it would be a good approximation - certainly acceptable compared to a subjective human assessment of 'bright/good/bad/average'.
Perhaps what you need to do is to make some measurements (using a smartphone or old-style lightmeter) over a period of a couple of weeks, at night in both cloudy and non-cloudy weather conditions, and with both full and no moon.
Write that up as a diary entry, and then people will be able to reproduce what you've done to measure illumination elsewhere?
