How Does Blue Light Impact Humans?


Although the use of blue light is an excellent solution to provide environmentally friendly lighting, it also poses a large number of health risks and disadvantages for humans. Before the creation of artificial lighting, overexposure to blue light was never an issue. Now, thanks to newer lighting technologies, our evenings and nights are flooded with illumination. As a result, excessive quantities of blue light and poor lighting, in general, can pose threats such as:

The European Ban on Halogen Light Bulbs


If you don’t actively stay up-to-date with developments in the lighting industry or international news, you may have missed the recent ban on halogen lighting in Europe. On September 1st, 2018, the use of halogen light bulbs was banned by the European Union. All halogen light bulbs are now prohibited and will be substituted with environmentally-conservative, energy-efficient light-emitting diode technology and compact fluorescent bulbs.

Environmental Impacts of Light Pollution


Through the incessant growth of both infrastructure and global human population, use of outdoor and city lighting has exploded. While most cities have prioritized effective lighting above all else, they have neglected the harmful impacts associated with light pollution. The most notable of these impacts: the encroached natural environment. We hope to go over what light pollution is, how it harms humanity, as well as which environments and animals are most affected.

The Necessity for Observatory-Friendly LEDs and SSLs


In October 2018, the Illuminating Engineering Society (IES) Street and Area Lighting Conference (SALC) convened in Orlando, Florida, to discuss the most recent developments in lighting solutions and energy efficiency. In contrast to previous SALC’s, this conference emphasized the challenges LEDs face when trying to simultaneously provide safe environments, meet the expectations of constituents, and remain observatory-friendly. Below is a summary of the event and a few thoughts from ourselves here at CWES.
