Prof. Andrew Coogan is a behavioural neuroscientist who specialises in the field of circadian rhythms, chronobiology and sleep. He is the director of the Chronobiology and Sleep Research Laboratory at Maynooth University. His particular research interest is in how the fields of circadian clocks, immunology and psychiatry may overlap.
To help with his research and to get a better picture of how light affects Irish people we’d really appreciate if you could take part in a sleep questionnaire that he has prepared at www.darksky.ie/sleep.
Created in 2003 by high-school student Jennifer Barlow, International Dark Sky Week has grown to become a worldwide event and a key component of Global Astronomy Month.

The rapid advancement of LED technology is unparalleled in the lighting industry, which has caused cities and utilities to reevaluate the specifications used for their street and area lighting applications. Early generation LEDs were typically 5000K or higher, which at the time was the upper end of the technology’s capacity for products that remained both economically viable and energy efficient.

Around the world streetlights are being retrofitted and replaced with LED lighting. The promise of lower energy consumption, no light spilling upwards, the ability to dim or cut off the lights seem good on all counts. However many installations are using lights that are to bright and “too blue” with a colour temperature of 4000K and above, despite the downsides to visibility and health from such lights.
Here’s a quick roundup of some recent international news from communities who are pushing for lower temperature and less intrusive LED street-lighting:
The UK National Parks Dark Skies Festival (18-26 February) is an ideal opportunity to try stargazing in some of the UK’s wildest areas.
Carrick-a-Rede and Oxford Island national nature reserve is the only Northern Ireland park to make the list.
