Here’s a quick and simple demonstration from the International Darksky Association (IDA) showing how unshielded lights at night actually make it more difficult to see, less safe and increase light pollution. It’s easy to fix though. Check out the video below…
The IDA says:
No one wants to look at a bare light bulb inside or out side your home!
This is a demonstration showing the impact of putting a shade over a bare light bulb. With no shade at all, a bare bulb’s light goes out equally in all directions and looking at the bulb directly can be uncomfortable and harm your eyes.
Putting a shade over the light directs the majority of the light downwards and out at an angle, permitting light to flow over a larger area and preventing wasted light and energy.
Choosing shielded, dark sky friendly lights improves visibility, safety, and a sense of security, while minimizing energy use, operating costs, and blinding glare. Do your part to promote a safe, pleasant nighttime environment in which we can all enjoy the splendor of the night sky by installing shielded outdoor lights at your home and office.
My story began more than 40 years ago looking up at the Moon with a small collapsible telescope my Father had. Encouraged by my parents, who bought me my very own telescope, a 4.5″ reflector, I began to explore the night sky from my family home backyard. Today I do astrophotography from my home in Kitchener, Ontario and also with remote telescopes located in New Mexico and Australia. Some of my images have won awards and have been featured online and in magazines.
