GUIDELINES FOR GOOD
EXTERIOR LIGHTING PLANS
Prepared by: The Dark SIV Society(http-,//www.darkskysociety.org/)
These guidelines have been developed in consultation, with.lighting professionals (with
experience in developing good lighting plans), f(.-)r comm.unities wishing to control light pollution
and preserve the star filled.night sky.
Lighting should be carefully designed with thought given to placement,intensity,
timing,duration,and color.
Good lighting practices will help to:
@ Promote Safety
More light than What is needed for safety is wasted light and is not necessarily better.
If the right fixtures are not designed and installed correctly, unsafe glare can result,
reducing the effect of lighting, contributing to accidents by hindering visibility.
Lighting that is too bright interferes with the eye's ability to adapt to darker areas..
* Save Money
Adhering to professionally recommended light levels provides adequate illumination,
Many of the fixtures recommended for use are much more cost-effective in the long run
because they are snore energy efficient. See this website for cost cornparisons:
http-//www.netacc.tiet/—poulsen/lightcost.htm]
* Conserve Natural Resources
Inappropriate or excessive lighting wastes our limited natural resources and pollutes
our air, land, and water by burning fossil. fuels for electricity.
@ BeBetter Neighbors
Excessive or misdirected lighting can intrude on the privacy of others where light or
glare lare trespasses over property lines.
* Retain Community's Character and Reduce Skyglow
Our clear view of the stars in the night sky is a resource to be preserved and protected,,
Stray and excessive lighting contributes to "light pollution" and unnatural "sky glow".
* Protect Ecology of Flora and Fauna
Research studies indicate that artificial night lighting disrupts the migrating,feeding,
and breeding habits of nanny Wildlife species, as well as growth patterns of trees. See
references on the website for the Intemational Dark Sky Association:
e Reduce Health Ibsks
Lig)[it at night not only disrupts your sleep but also interferes with your inimune system..
Recent research has also indicated that intrusive lightingmay reduce the production of
melatonin, a beneficial hormone.

Dear Supervisor Russell and Members of the Southold Town Board,
This week's meteor shower really sent the message home that we need to protect our night sky from
urban light pollution—for humans and nocturnal creatures alike. Thank you for taking the first steps to
regulate light pollution through past amendments to Chapter 172 of the Town Code and upgrading the
town's street lights with full cutoff fixtures and 2700K bulbs in 2019. Unfortunately,urban light
pollution continues to degrade our night sky.
As a resident who enjoys looking up at the stars at night and as a farmer who relies in part on nocturnal
pollinators to pollinate my crops, I ask that the Town take the following next steps:
1) Support and memorialize in a resolution International Dark Sky Week(April 11th-17th)whereby
residents should turn off all unnecessary lighting and go out and look at the stars.
2)Utilize Channel 22 to educate and inform the community of good lighting practices and the current
Southold Town Code on outdoor lighting.
3) Create a webpage on the Town of Southold website under code enforcement dedicated to good
lighting practices and highlighting the current Southold Town Code on outdoor lighting.
4) Survey all Town of Southold properties for compliance with Chapter 172 and make immediate
necessary changes to meet or exceed the current code.For example, there are floodlights illegally
uplighting the Henry Prince Building on the corner of Youngs Avenue and Main Road. The light
fixtures at the entrance to the Southold Town Recreation Department(aka Senior Center) on Peconic
Avenue direct cones of light upward. In addition,the floodlights on Peconic Lane's Community Center
and Southold Town Recreation Department Building both have multiple unshielded floodlights in use
and are not motion activated.
Thank you for your work to date on starting to protect the night sky.As a community,there is a lot more
work to be done but I am confident that together we can make a difference.
Sincerely,
Laura Klahre

RE: International Dark Sky Week April 11 — 17, 2021
This is a one-week event which was initiated by a high school student ten years ago to
bring attention to the beauty of the night sky by asking that people shut off unnecessary night
lighting and go outdoors to view the night sky.
Southold has enacted numerous initiatives to help reduce intrusive and excessive night
lighting. As is always the case, more can be accomplished by bringing awareness to the reasons
for these initiatives.
This is why we are supporting your local civic, environmental, and business groups by
asking for your consideration to issue an official proclamation and to loin in the international
observance of"Dark Sky Week" April 17-25 th, and each year tlierea er.

Dear Supervisor Russel and Town Board Members:
The Mattituck-Laurel Civic Association, in conjunction with the newly formed Southold Dark Sky
Coalition, isasking the Town Board topass m resolution tmjoin incelebrating International Dark Sky
Week,April 11'l7,2D22.
International Dark Sky Week is a weeklong celebration of the night. It encourages people around the
world to come together(online)to celebrate the night and engage with authors,creators,scientists, and
educators whose works have been vital tothe movement to protect the night from light pollution.
Itis also an opportunity to explore and better understand the impacts of light pollution in Southold
Town and how individuals,communities, and the Town Board can act locally to lessen light pollution's
impacts.
In addition to the world-wide activities,the many North Fork organizations and individuals making up
the Southold Dark Sky Coalition,will sponsor a series of awareness,education,and celestial observation
occasions leading up to International Dark Sky Week. Local activities will involve local students and other
citizens, multiple community organizations,the Matt|tuck Park District, and the Custer Institute,The
Southo|dDarkGkyCoa|idoma|soai|| neviewvanddiacussGouthm|dTom/n's"darkuky" |ighting code and its
contribution toquality oflife here.

defined,Any word or term not noted below shall be used with a meaning as defined in Webster's Third International Dictionary
nfthe English Language,unabridged (or latest adit|ons):
AREA LIGHT
A luminaire designed for illumination of a broad area. Area lights include, but are not limited to, streetlights, parking lot
lights and yard lights over i'Bomlumens.
ESSENTIAL LIGHTING
Light that is used For a specified period of time, which is necessary for location identification, safety, security or public
circulation purposes.
EXCESSIVE LIGHTING
illuminance levels beyond that which is required for safety�as recommended in |ESNA Recommended Practices,or higher
than five footcandles on any lit surface unless a higher level is indicated on the Table of Limits of Illumination Levels,
EXTERIOR LIGHTING
Lighting that is mounted, located, |amped or used whether inside or outside, to illuminate outdoor features. For the
purposes of this chapter, lighting which is installed indoors but which is intended to illuminate an area outdoors shall be
considered exterior lighting.
FIXTURE
ThecomF|ete|ightingaasenmbly(indu6|ngbutnot|imitedtothe |amp,hausing,bmUast,timers,photocells,reflectors,cover
glass, lenses, louvers, and shields), including the support assembly (pole or mounting bracket), For purposes of
determining total light output from a light fixture, lighting assemblies which may include multiple lamps shall be
considered asasingle fixture.Also referred tmama"|umimm|re.°
FOOTCANDLE(FC)
The basic unit of illuminance (the amount of light failing on a surface). Footcandle measurement is taken with a light
meter, one footcandle is approximately equal to the illuminance produced by light source of one candela in intensity,
measured on asurface at one foot distance from the source. Horizontal footcandles measure the illumination striking
horizontal plane.Footcandle values can bemeasured directly with certain handheld incident light meters.
FULL CUTOFF(FCO)
AdassiHcation fora luminaire designed and installed where no light is emitted z$ orabove a horizontal plane running
through the lowest point on the luminaire. In addition,the luminous intensity (as measured in candelas) emitted at any
angle from Boc, up to goO cannot exceed a numerical value equal to io%of the lumen rating of the lamp,as reported in a
photometric report from the manufacturer. Acutoff; or semi-cutoff design, allows m restricted amount of light emitted
above the horizontal and a noncutoff provides no restriction against light emitted above the horizontal.
FULLY SHIM DED
1/21/2020 Town ofSouthold,NYLightingOutdoor
A luminaire constructed and installed in such a manner that all light emitted by it, either directly from the lamp or a
diffusing element,or indirectly by reflection or refraction from any part of the luminaire,is projected below the horizontal.
It is the same as afu|| cutoff luminaire but without any restrictions on light distribution below the horizontal plane,and it
can 6eidentified without amanufacturer's report.
GLARE
Unshielded light from a light source that may result in nuisance or annoyance,discomfort or visual disability,
HOLIDAY LIGHTING
Temporary lights installed on a residential property which are installed in connection with holiday or religious observances
between Thanksgiving and the following January 15.
UESNA
Illuminating Engineering SodetyofNorthAmehca0ESmr!ESN/),mourganizationthctestab|ishesupdate6standardsmnd
illumination guidelines for the lighting industry.
IESNA RECOMMENDED PRACTICES
The most current publications of the IESNA setting forth illuminance levels for different task areas,e.g.,walkways,streets,
sports lights,etc.
ILLUMINANCE
The density of light failing on any point of a surface, usually measured in footcandles in the United States. See
"footcand|es."
LAMP
The source of artificial light asdistinguished from the fixture.
LANDSCAPE LIGHTING
Lighting which is positioned and aimed to illuminate foliage, driveways, walkways, patios, decks and other exterior
pedestrian areas,whether ornot mounted onastructure.
LIGHTING
Light fixture mrlight source,orthe effect mflight,and all apparatus and wiring topower artificial light,
LIGHT POLLUTION
Any and all nuisances caused by the adverse effect of man-made light, including but not limited to glare, light trespass,
skyg|uw, v|sua| clutter, and wasted energy due to excessive orunnecessary lighting; orartificial light that unnecessarily
diminishes the ability to view the night sky or is disruptive to flora and fauna.
LIGHT SOURCE
The light-emitting part or parts ofafixture, consisting of the lamp or lamps and any transparent or translucent covering
over the lamp,as well as any refractors,reflectors,prismatic lenses,mirrors,or diffusers which emit or transmit light.
LIGHT TRESPASS
Light projected across property lines or into the public right of way when it is not required or permitted to do so.
LUMEN
A omh used to measure the amount of light that is produced by light source. The lumen quantifies the amount of light
energy produced by a lamp at the lamp,not by the energy input,which is indicated by the wattage.
LUMINAIRE
The complete lighting assembly (including the lamp, housing, ballasts, photocells, reflectors, lenses and sNe|dd' less the
support assembly (pole or mounting bracket); a light fixture. For purposes of determining total light output from a
luminaire or light fixture,lighting assemblies which include multiple unshielded or partially shielded lamps unasingle pole
orstandard shall beconsidered asasingle unit.
MOUNTING HEIGHT
The vertical distance cfthe light source from natural grade.
hupm:6er,ode360.com/14641610 27

NONESSENTIAL EXTERIOR LIGHTING
Lighting which is unnecessary for pedestrian passage and not generally useful (e.g.,decorative and landscape lighting).This
includes lighting intended for a specific task or purpose when said task or purpose is not being actively performed (e.g.,
parking lot illumination and wall-mounted perimeter lights after business hours).
PARTIALLY SHIELDED
A light fixture that is not fully shielded but incorporates a partial shield around the lamp by opaque barrier(s) such as
louvers, shields, and other means in order to prevent the light source from being visible from across property lines, into
waterways,or roadways.
SKYGLOW
Glare or illumination of the night sky,whether direct or reflected.
UNIFORMITY RATIO(-U RATIOJ
A ratio that describes uniformity of illuminance across an area.The uniformity ratio may be a ratio of the maximum-to-
minimum illuminance or the average-to-minimum illuminance. For example, if the Illuminating Engineering Society
recommends an average-to-minimum ratio Of 4:1 fur a parking lot,the minimum illuminance should be no less than 1/4 of
the average illuminance across the parking lot.
UNSHIELDED FIXTURE
A fixture which,as designed or installed,emits all or part of the light above the lowest part of the light source,
§

approved by the Building Department or the Planning Board.The maximum number of lumens for commercial uses is
25,000 lumens per acre. For proposals in residential and limited business districts the maximum number of lumens is
lm,000 lumens per acre. The Town recognizes that not every situation will require lighting, and excessive or
unnecessary light shall be avoided. Appropriate lighting levels are dependent upon the general nature of the
surroundings and the Building Department or Planning Board may require more or less than those listed in the IESNA
Recommended Practices Guidelines. Illuminance level measurements for parking lots,sidewalks, and other walkways
shall include any light from nearby side-mounted building lights, freestanding sidewalk lights affected by side-
mounted building lights, and existing or proposed streetlights. In no instance may any lighted surface' as installed,
exceed five footcandles,ms measured horizontally nrvertically byalight meter unless itcan be demonstrated that a
higher level is necessary for the proposed use {higher levels should be based an guidelines established either in the
|ES0A Handbook or similar professional or governmental guidelines or regulations, (e.g., federal standards
establishing lighting levels around automated teller mnmchines).
( ) The light source shall not exceed 3,000Ke|vin.
(4) Streetlights shall be full cutoff high-pressure sodium, low-pressure sodium,
mr fluorescent, unless otherwise
determined that another type is more efficient. Streetlights along residential streets shall not exceed seventy-watt
high-pressure sodium (hps) light with a lumen output of 6,400. Street||ghts along nonresidential streets or at
intersections shall not exceed i6o watts hps each, with a lumen output of 1,6ou\ except the lights at major
intersections on state highways shall not exceed 250 watts hps. If light type other than high-pressure sodium is
permitted, then the equivalent output shall be the limit for that light type. Exception: replacements of "historic"
lighting design where the replacement of the luminaire piecemeal with compliant luminaires would unacceptably
Jegadethe aesthetic characteristics ofthe existing lighting design.
