As part of the 2009 International Year of Astronomy our Colleagues at the Kuffner Sternwarte Observatory in Vienna produced a light meter that could be used to monitor light pollution. More details on the project and the meter are available at lightmeter.astronomy2009.at (use login Guest and IYA2009).
There are three stations in Ireland. One in Monasterevin (I’m not sure if it is active), one on the roof of the physics building in Trinity College Dublin, and the one I maintain in South Dublin.
