[HISTORY: Adopted by the Suffolk County Legislature 8-24-2004 by L.L. No. 26-2004 (Ch. 108 of the 1985 Code). Amendments noted where applicable. Uncodified sections of local laws amending these provisions are included at the end of this chapter.]149a Uncod LL Pro
This Legislature finds that the County of Suffolk and other governmental entities should require the use of fully shielded fixtures when installing new or replacement light fixtures.
This Legislature hereby finds and determines that unshielded light contributes to light pollution which makes it harder to see a starry night sky, thus interfering with astronomical observations and recreational enjoyment.
This Legislature further finds that directing light more accurately onto areas intended for illumination prevents the waste of energy, reduces energy costs, and lowers emissions from fossil-fuel-burning facilities needed to produce this excess energy.
This Legislature also finds and determines that there is increasing scientific evidence demonstrating that misdirected, unshielded, excessive or unnecessary outdoor night lighting can have detrimental effects on the environment and the human physiology.
Therefore, the purpose of this chapter is to require that new or replacement outdoor lighting fixtures purchased and installed by the County of Suffolk, on County-owned facilities, will be fixtures designed to reduce light pollution.
As used in this chapter, the following terms shall have the meanings indicated:
- Any department, division, bureau, board or commission, or agency of Suffolk County government, the expenses of which are paid in whole or in part from Suffolk County funds.
- CORRELATED COLOR TEMPERATURE
- The perceived color of the light emitted by a lamp, expressed
in Kelvin (K) units. The higher the Kelvin rating, the "cooler" or
more blue the light will be.[Added 9-12-2013 by L.L. No. 37-2013]
- County buildings; parking lots; docks; and all County infrastructure except as specifically exempted by § 149-4 of this chapter.
- FULLY SHIELDED LUMINAIRE
- 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.
- The unit of measurement used to characterize the color of
light emitted by a lamp.[Added 9-12-2013 by L.L. No. 37-2013]
- A light bulb or other component of a luminaire that changes
electricity into visible light.[Added 9-12-2013 by L.L. No. 37-2013]
- A complete lighting unit, including a lamp or lamps together with the parts designed to distribute the light, to position and protect the lamps, and to connect the lamps to the power supply.
- PERMANENT OUTDOOR LUMINAIRE
- Any luminaire or system of luminaires that is outdoors and that is used for more than 10 days in a period of 365 days.
[Amended 9-12-2013 by L.L. No. 37-2013]
When purchasing new or replacement lighting, all County departments shall include a specification in a solicitation for the purchase of any permanent outdoor luminaire that requires the provider to offer for sale to the County of Suffolk only luminaires that 1) are fully shielded and 2) use lamps with a correlated color temperature no higher than 3500 Kelvin for all lamps purchased through December 31, 2015, with all lamps purchased thereafter having a correlated color temperature no higher than 3000 Kelvin. All outdoor luminaires in all County facilities shall be replaced in accordance with this section. All new outdoor luminaires shall be installed in accordance with this section.
Any replacement lamps for luminaires purchased by a County department pursuant to Subsection A of this section shall have a correlated color temperature no higher than 3500 Kelvin for replacement lamps purchased on or before December 31, 2015, with any subsequent replacement lamp having a correlated color temperature no higher than 3000 Kelvin.
The requirements of § 149-3 shall not apply as follows:
Federal or state funding precludes the County of Suffolk from imposing the requirements of this chapter.
The luminaire is an historic or decorative luminaire which is part of a continuous lighting design where the replacement of the luminaire piecemeal with compliant luminaires would unacceptably degrade the aesthetic characteristics of the existing lighting design.
Situations where there are special requirements, such as sports facilities, tunnels, traffic control devices, navigation lighting, airports, underbridge lighting, natural and cultural monuments, or flag lighting; provided, however, that all such lighting shall be selected and installed to shield the lamp and to minimize upward lighting, glare and light trespass to the greatest extent possible.
Situations where a written determination with findings has been made by the Commissioner of Public Works that a specified exemption to any requirements of § 149-3 is necessary and appropriate for a compelling safety interest which cannot be adequately addressed by any other method. Such determination shall be filed with the County Executive and the Clerk of the Legislature.
This chapter shall take effect on the 90th day immediately subsequent to filing in the office of the Secretary of State.
