Clayton presented a scaled down version of the Fountain Hills Dark Sky Association’s Initiative aimed at shielding and kelvin during a Toastmasters meeting.
The simple message in this apresentation was to use warm lights, not use bright white lights; a 3000k or less. One can easily locate the kelvin rating on the back of a box or bulbs. Also, he spoke about shielding. This simple concept means using fully shielded lights that don’t emit light beyond a 90 degree radius.
There are many more presentations planned by the Fountain Hills Dark Sky association. Take a look at our schedule, here.
