Monthly Meeting October – Outdoor Lighting – sky glow, human health and ecosystems with Steve Butler

This talk will cover the change in outdoor lighting over the past decade with reference to the “new” technology of LED light sources. Included will be the implications of light colour on sky glow, human health and ecosystems. The monitoring of these new sources will be touched on as well as recent developments in New Zealand.

Steve is  a long time advocate for reducing light pollution including as the leader of the RASNZ Dark Skies Group since 2004. I am the current RASNZ President and am Chair of the Board for the Aoraki Mackenzie International Dark Sky Reserve.
