Or uplight on stake tipped over and just happened to point towards intersection.

Or it was a big ground-mounted PAR 36 doing same.

I never thought outdoor lighting (http://www.utahlandscapelighting.com/contact-us) could do that. Nice

It could be dangerous. It would feel like driving toward a car running with it's high beams on. PARTICULARLY if it was a PAR 36 which was designed by Mr Edison for Mr. Ford's tractor headlights.

If it's an intersection with a stop sign and the glare was just to the side of the sign it could be very dangerous.

"Arrest" that light.

I know a single glaring landscape luminaire seems a small problem, easily remedied, and for young and middle aged people it is. For the elderly glare, particularly disability glare, is dangerous. As the eye ages it becomes less able to respond to changes in light levels. What appears to be only an annoyance to a 21 year-old may become blinding for their grandparents and certainly for their great grandparents.

I've written and copyrighted a document on Responsible Landscape Lighting. My work on the document began in cooperation with the IDA - International Dark-Sky Association. You may find it interesting. You will find it on my web site. Go to: <www.WLLD.us/home/responsible.shtml>

In addition, you may want to look at my wife's web site at <http://www.nmlightingdesign.com/topics/index.php> This section deals with the human eye and offers much information that is essential for those who are attempting to learn the practice of landscape lighting. We are designing for the human eye and we must understand how the eye works.

Is this obvious? Apparently not, based on the practice I've seen all over this country.

I hope no one thought that I was making fun of this situation.
Mine was a play on words. As a senior myself, I know I don't adjust to bright lights as I did when I was younger.

Tom, great, great articles from you and your wife. Thanks for your contributions.

This isn't from Tom's web page. It's from a 2008 thread on this forum that I found while studying the archives.
It is worth reading now or reading again if you remember it from the first time around.

"What a Dark Sky means to me"
Once I lived in Vermont... On any cloudless night, with the moon a crescent or less, I could walk out my door, look up and see the Milky Way.

There are more than 6.6 billion people living on the earth today. At least 2/3 of them cannot see the Milky Way. They live in cities, or too close to cities, with poorly designed electric light.

More than 4.4 billion of the inhabitants of our Earth can only see about a dozen stars and the moon. Most of the Earth's residents have no idea of what it means to stand looking up until your neck aches while you try to understand what the magnificence of the dark sky filled with stars is all about.

I believe we, all humanity, are diminished when we are unable to study what creation looks like for ourselves. We grow up with a distorted understanding of how big creation really is. We become adults with no scale to help us gauge how important we are in the universe. We don't understand what big really is; we can't see it anymore.

We no longer dream and wonder the way we did when we saw the stars.

I think we've lost contact with one of the few experiences we share with all who went before us and I think we are much poorer for the loss.

That's why I think it's important there be many places set aside on this earth for parents to take their children to see the Milky Way. If a community decides to be one of those places, I believe we can help them to achieve that goal and still have the opportunity to share our love of light in the landscape.

It's not easy, but nothing that's really worth doing is easy.

Tom

Thanks for the kind words Steve.

Phil, I'll take any opportunity to pontificate on IDA issues and human vision. Thank you for rummaging around and holding the door open for me.

I believe, as an industry, a craft and occasionally an art, a deep understanding of both are essential for our acceptance as responsible and sustainable members of society.

Hi Tom,

This is my last post on this thread since we're way off topic, but I'd love to turn some discussion more towards some of the amazing aspects of human vision - especially in the area of compensation, accommodation, and extrapolation. For example, many don't realize that only a small part of the visual field is in focus, and that different parts of the visual field differ greatly in their perception of color, contrast, and brightness. Then there are topics of light and health that are just now being discovered. All very fascinating. Unfortunately, I don't think this forum is the best place to delve into these topics. Do you know of other forums that may be better?

Hi Tom,

.......... Unfortunately, I don't think this forum is the best place to delve into these topics..........

Steve,
If any forum is the right place, why not this one?

Nothing against this forum, but I believe many who could provide more insight into physiological and psychological research aren't here.

I should note that this forum's rules prohibit mentioning other forums - so I'll drop the topic - if anyone has suggestions, please PM me.
