Yes...but don't complain every time a neighborhood cat or raccoon
sounds the buzzer.
re: or even use the low voltage as input to my house alarm system.
Call your alarm company for a answer specific to your system.
Oh dear why do people make assumptions?
A low buzzer, like noticing "Oh one of the outside lights is on. I
wonder why?" and then investigating is not a nuisance. It merely tells
you that one of the neighbous kids has walked past on the way to some
evening event at the nearby school!
No raccoons here; neighbours cats are known and usually in at night.
Also do not assume the alarm is tied into an alarm company, it's not.
However on the odd occasion we are away it sounds across the street in
my neighbour's house (I do the same for them if/when they are away)
and operates a small horn and some other devices I will not mention
Not to mention the increased costs of installing and maintaining the
motion sensitive stuff. The increased costs related to replacing lights
that burn out faster because they are turned on and off more often.
Etc., etc., etc.,
Ignoring the costs of setting up and running a system, even if
computer run. I am not sure how they would spend the 20 seconds of
savings before kids decide that turning on the lights is this
generation's equivalent of calling a store to see if they had Prince
Albert in a can.
I hate street lights. They block out the night sky. Thankfully I don't
have a street in front of my house but I can see one down the road.
They can all be put on motion detectors for security. No need to have
lights on when nobody is home or anywhere around is there? It's a real
ignorant energy wasting idea.
For the same reason that street lights are (usually) not on during the
daytime. Street lights are on at night so people (mostly) and animals can
They also act as a deterrent - roaches don't like light.
I live across the street from an apartment house. There is a largish street
light in front of my house that illuminates the street (of course) and the
parking lot of the apartment complex. Every time the light goes out (the
last time because some fool hit it while doing about 100mph) the goblins at
the apartment house come out to play. For all I can tell, they are dancing
around semi-naked while chanting unintelligible incantations to something
that cannot even charitably be called music. It's spooky and the only thing
I can do is maintain a well-armed vigilance lest their witch-doctor lose
control or they run out of virgins.
It is harder to sue someone in Germany too. In the US the day someone
is robbed or has a fender bender in an unlit parking lot, the cost to
the business will probably be a few years worth of electricity. Same
with municipalities. It is not economical to not have street lights.
Maybe. More likely the low crime streets with affluent residents
don't shoot their lights out and do insist on them being repaired.
The low budget city works depts don't put a lot of effort into fixing
lights in high crime areas. So yeah I'd expect a brighter street is
probably safer crime wise, but wouldn't ascribe the cause to the
Bright lights don't keep the raccoons out of my garbage cans but
movement does. Lighting a property when nobody is observing just
helps the criminals work faster and safer.
I would bet auto sales lots use the lighting for advertising purposes,
not crime prevention.
Do you know what is considered more important by the average American,
the sun or the moon?
Overwhelmingly the response is the moon. It's a no-brainer. The moon
is out at night, when it's dark and we really need the light. The sun
is out when it's already day. Doh.
Not talking about street lights in any particular country, including
BTW this same item was posted on a news group populated by those from
a European country.
Their response were, if anything more factual, giving examples of
communities who do and do not turn off their street lights after
certain times, at night. Along with generally sensible comments and
references and quotes from newspaper articles about street light
situations. Also some technical comments about street lighting
techniques, retrofitting older and/or newer street lighting systems.
There was very little (or nothing) in the way of smart-alecky or nasty
An interesting debate however, from both the North American posting
here and that other one.
BTW; a detail. Some communities install street and other lighting that
minimizes light pollution upwards, directing a greater percentage of
the light downwards and onto the areas where it is most effective. One
benefit is to assist astronomical observations.
Thanks anyway to all who posted for throwing some light on the topic.
It's after 1.00 AM here and in this community with some 300-400
municipally financed street lights nothing moves, except maybe for the
one motorist heading home after working late. And the lights will
shine on until around 6.00 AM. Our electrcity is hydro generated so
there is actually no change in pollution/global warming by the
consumption of the electricity as would be the case with burning coal
or other fossil fuel..
I don't suppose you can reveal that newsgroup. <sigh>
Oh, BAD us. <snivel> Can't we all just get along?
I'd LOVE to read it - the measured, level-headed, polite thread from the
continent widely known for universal tranquility and cooperation.
But no citation. Nice. :\\
Oh, please. :(
The only street, parking lot or other lighting fixture I have *EVER*
seen that is NOT directing its output down is one that is DAMAGED - or
directed at another, Earthbound item, i.e. flag, sign, etc.
The folks at Mount Palomar are grateful, I'm sure.
Regardless, the best astronomical observatory has been orbiting our
planet for 18 years. Unfettered by earthly light "pollution" <gag> and
atmospheric distortion (bring back CFCs for the benefit of ground-based
observers<g>), Hubble has peered further and deeper into the cosmos,
mostly for the benefit of countless computer displays of cool wallpapers
...and those lights are PRECISELY WHY nothing moves.
It must be all the lattes, bean sprouts, tofu and other soy "food" that
have caused so many formerly, presumably intelligent folks to buy into
ALL the "green" hype. When it comes simply to "energy consumption",
it's all bad. There is no consideration given to cause and effect,
collateral benefit vs detriment and historical evidence of value.
Perhaps, but what about the poor, oppressed FISH? Has the dam operator
installed "ladders" yet? Have they yet installed discharge water
coolers so that the fish don't gather near the outlet because they
prefer the warmth? What about the vaunted Snail Darter?
My local power utility recently had the nerve to reveal they were
considering building another nuke. Progress is being made, albeit
slowly, no thanks to the late operators (experimenters) of Chernobyl and
Hanoi Jane's alarmist movie.
Not to worry, though: There will always be SOMETHING to keep
environmentalist extremists mad and militant. Come to think of it, if
they REALLY wished to curb CO2 emission, they'd shut up. Fat chance.
Fortunately, there are few enough of them to make much difference in
