Steve Davis is a very bright individual who had much to do with getting the
LP awareness ball rolling in New York State, and even helped to get me into
the fold. He also has high principles about what must be in an LP law, which
is to be admired.
However, it must be known that while no dark sky people in NY like the
proposed ammendments, MOST of us at SELENE want to see the bill signed into
LAW as ammended as a first step toward reducing LP, and work on future
ammendments later, as has been done successfully in CT.
We do NOT feel we will have a better chance to get a bill stronger than
this, maybe EVER, if this bill is VETOED.
In fact, there is a very good possibility that the Governor will veto this
bill as AMMENDED! If vetoed, we don't think it will be easy to pass an LP
bill again in the near future at least.
Therefore, most of the people at SELENE are calling for as many people as
possible to contact the Governor is SUPPORT of A5352 AND the ammendment to
that bill, A9757.
And quickly as possible, time runs out on Feb 8th, and the sponsors are
holding a press conference in Albany which we will attend in support on
Tuesday!
Any further discussions about the incremental nature of getting LP bills
passed and then ammended are welcome.

Right on. There is nothing sacred about 6:1. It is a guideline.
An engineering tradeoff has to be made between uniformity and

Subject: Northeast Astronomy Forum May 18th-19th
New York State has been active with legislative Light Pollution bills
the last few months. So it's only fitting that NYS is the home of
the best astronomy/telescope show!
May 18th-19th the 11th Annual Northeast Astronomy Forum is being held
at Rockland Community College in Suffern, N.Y. Many members here
have attended, but many others may be new.
It's a great place to network with other Dark Sky activists and
fellow astronomers. Our featured speaker is comet hunter David Levy,
of Shoemaker-Levy 9 fame. Dozens of vendors, top-notch speakers and
workshops, raffles and door prizes, and (new!) children's activities
and planetarium shows.
We're hoping to make this our best attended NEAF yet. The more
successful NEAF, the more our club can do to assist light pollution
efforts.

Subject: Re: Gas station canopies: readings in Manchester, NH analysis
Just FYI; Here are some readings I took in Manchester NH: Mike in NH
Gas Station Lighting Analysis
For Manchester, NH
Using a SPER Scientific 840020 Light Meter, brand new, calibrated 11/2000,
several readings were made at Manchester gas stations as seen below. Note
that the measurement levels are made in ‘Foot Candle’ units.
On the attached pages are the IESNA recommendations for outdoor lighting,
specifically for gas stations. The maximum Foot Candle recommended is 10.
However, note that in the specific situations in Manchester, the maximum
recommended level is only 5 Foot Candles since the surrounding areas are
dark.
The readings were made while standing under the gas station canopy as if
fueling a car. The readings were completed at night between 7:30-8:30 pm
under moonless nights with light overcast in early March 2000.
Station Location Reading in Foot Candles
Citgo Hanover/Rt93 25.1
Mega X Queen City Ave. 40.5
Citgo/7-11 Mammoth Road 65.0
Sunoco Queen City Ave 32 (note this reading was done in August 2000
with an older light meter. They have gone out of business since, but the
lighting remains)
Mobile Rt. 28/Wellington Rd 42.5
Citgo/7-11 Bridge/Maple St 55.1
Sunoco Amoskeag Bridge 17.9
Texaco McGregor St 78.7
Mobile McGregor St. 81.4 This light was brightest recorded in the
city.
Exxon Granite St. 44.4

Hi Paul:
There are none that I am aware of. When I contacted NOAA in early 2000 the
Director told me their DSMP biomass study program had concluded in the late
1970s, however, the satellite used for that research is still up there
collecting data. This satellite was launched into orbit so scientists could
discover more about the causes and effects of global warming. The biomass
study considered all kinds of things ranging from rotting vegetation to
ground fires, to energy waste thrown to the sky from obtrusive outdoor
lighting and many other influences.
The results coming back from this satellite are digital data streams rather
than actual photographs from my understanding. These are the some of the
data that Cinzano, Falchi, Sullivan, et al have applied to their light
pollution reports. The interpolation of that data that has provided the very
high quality images that we have all seen.
It would be great to see before and after effects, but that process takes an
enormous amount of time to take effect. For instance, I suspect that before
Connecticut shows all FCO lighting on the roads the process of changeover
will take at least 20 years, if not longer. This is because the FCOs only
get replaced when the old lights wear out and some have been in place
chugging glare into the air since the 1960s!
Also, it takes an enormous amount of time to interpolate the satellite data
and generate an image from it. Someone directly involved in this once told
me it takes a couple of years for the whole process to be completed. By the
time an image is generated it is already out of date but it does provide a
valuable record of the progression that is occurring. The evaluation of many
orbits is used to assemble a mosaic that does not include cloud covering and
ground fires.
How that information is determined and quantified is beyond the scope of my
comprehension and those who are directly involved in this process can
elaborate much better than I can.
Clear skies and good seeing,
Keep looking up!

Subject: Re: Fw: Light meter need
I still use my old Spectra Professional - just because I've owned it for 20+ years. It is an analog meter that measures directly in footcandles when using the flat disc and no slides. It was $300 bucks. No battery needed. You may need finer scales if you are measuring light trespass in your code, though. Or you can use a spotmeter to solve for the trespass level in footcandles.
Check out this link I just found for Extech brand light meters:
http://www.zefon.com/analytical/measure/light/index.html
They have some digital foot candle meters in the $69 - $169 range that run off of a 9v battery. The heavy duty one has settings for HPS, etc. Might be worth a look. If you call them be sure to ask how well they perform in the 0-10 footcandle range.
(Let us know how you make out.)
Hope this helps a bit.
Maryann Arrien
(PS to the Dark Sky Listers:
Jump in there, you guys! - so what is everybody else using?)
Can someone out here recommend a reasonably priced, calibrated light meter make/model - suitable for a code enforcement officer to use to look at compliance?

Subject: RE: Fw: Light meter need
To All: I have used a Hagner Model S1 since the early 1970's. It has a
remote, light sensitive silicon diode receptor, an analog output PLUS a
luminance meter. It still continues to serve me as a reliable and
versatile meter.
I purchased a Hagner Model EC-1 hand held meter about 15 years ago and
it has proven more than adequate for most of my work. The Cooke
Corporation handled the Hagner instruments in the earlier days and sold
me this meter originally. They continue to support these instruments
and I recently had the EC-1 calibrated by this company. The present day
equal to the EC-1 is shown on:
http://www.cookecorp.com/buyit/index.html
It is the Cal Light 400 and I can heartily recommend this instrument.
NEW SUBJECT: - Licensed Professional Engineers - Certified Lighting
Designers.
I have been following David Keith's and others input on this important
subject. Several of us within the IESNA have worked over the years to
encourage the that organization to put a certification program in place.
It would be different than the "LC" designation now being offered by the
NCQLP. The LC designation, as it is presently constituted, will not
work for the certification program. It is a lengthy subject and I would
be pleased to lead a discussion during the upcoming IDA Annual
Conference if any of the attendees are interested.

Here is an illuminance meter, that reads in

It's only $98, or $128 with NIST traceable

Dave,
Are there any studies of traffic safety experience comparing roads with
lighting engineered with FCO versus cutoff?
How about safety comparisons on roads before and after refitting with FCOs?
This information is an important piece of the puzzle.
Would appreciate hearing from anyone who knows of such studies.

Subject: Caltrans lighting regs
Re: Calif. (Caltrans) fco lighting regs.
http://www.dot.ca.gov/hq/traffops/signtech/signdel/chp9/chap9.htm#Section_12
Here are the Caltrans regs; the lighting section for state highways.
It calls for *full cutoff* hps lamps. If fco state hwy. lighting is
good enough for a state of 34 million people, it
ought to be ok for everywhere else - at least for those
states who want their drivers to see the road.
Steve Pauley
====================================================
From Traffic Manual Chapter 9
Section 9-12 - Luminaires
9-12.1 General
Normally, the luminaire for a new installation of safety lighting on State
highways is a full-cutoff type using a high pressure sodium lamp.
9-12.2 Roadway Luminaires
On freeways, 200-watt lamps shall be used with 9.14 m mounting heights and
310-watt lamps shall be used with 12.19 m mounting heights. On conventional
highways and at the intersections of freeway ramps with surface streets,
150-watt lamps may be used with either 9.14 m or 12.19 m mounting heights.
Utility owned semi-cutoff type luminaires should be provided with glare
shields in rural areas.
9-12.3 Soffit Luminaires
Soffit luminaires are special fixtures either suspended from or
flush-mounted into structures to illuminate the roadway under the
structure. They shall be used with 70 or 100 watt high-pressure sodium
lamps, depending upon lighting requirements. Normally, the fixtures should
not be located over the traveled way on freeways.
9-12.4 Wall Luminaires
Wall luminaires are fixtures designed to be surface mounted on vertical
surfaces. However, a simple right angle bracket permits mounting them from
a horizontal surface such as the bottom slab of a box girder. They are used
with the same lamps as soffit luminaires.
