As the IES looks to inspire growth in the lighting industry and become a more inclusive Society, it is essential that we consider our membership structure from the global perspective. It has become increasingly evident that our current membership dues rates are not attainable for some individuals outside of North America, and reduced membership dues are necessary to address the needs of lighting professionals living and working in Emerging Countries as defined by the World Bank (specifically for those categorized as Low-income and Lower-middle-income economies).
