I appreciate your efforts to experimentally assess light emanation. I think there may be one key
weakness and another of more complex possibilities.
First, a significant amount of light reaching the property fence will result from the overhead
lights being reflected by surfaces, especially water and wet light colored pavement. Meaningful
effort is required to simulate those effects during the experiment.
Secondly, the effects of multiple light sources will combine in producing observed levels at
various loci. Two, three or four lights spaced as close as anticipated will likely produce results
with positive apparent interactions. By putting only two lights at once, at opposite ends, how
would anyone be able to reasonably foresee the results of a cluster (as close as planned)?
