I have been asked by a local conservation group, to present an argument for
lighting restrictions at a proposed development, that will go before a
regional municipal board.
At issue is the sky conditions at the site. In short, developer proponents
have hired a lighting engineer who has used a luminance meter to form the
basis of his position.
Are there any documents available that explain the differences and
similarities between a SQM unit and a luminance meter and why a SQM unit is
better suited to measure sky brightness?
