Socorro City Zoning Code
ARTICLE XV
Outdoor Lighting
§ 250-15.1 Purpose.
This article is intended to permit adequate lighting and promote public safety by encouraging the use of outdoor artificial illuminating devices which do not have a detrimental effect on astronomical observations resulting from the emission of undesirable light rays into the night sky. All outdoor lighting installations shall conform to the provisions of this article and all other related codes of the City of Socorro, specifically the Uniform Building Code (UBC), as amended, and shall require permits and inspection.
§ 250-15.2 Approved materials and methods of installation.
§ 250-15.3 Definitions.
As used in this article, the following terms shall have the meanings indicated:
Any private individual, tenant, lessee, owner, or any commercial entity, including, but not limited to: companies, partnerships, joint ventures or corporations.
The initial installation of an outdoor light fixture, as defined herein, following the effective date of this article, but shall not apply to those outdoor light fixtures installed prior to this date. Any installation of outdoor lighting fixtures shall be subject to an electrical permit and/or a building permit and conform to the Uniform Building Code and/or the National Electric Code.
Outdoor artificial illuminating devices, outdoor fixtures, lamps and other devices, permanent or portable, used for illumination or advertisement. Such devices shall include, but are not limited to, search, spot, or flood lights for:

A.
Shielding. All exterior illuminating devices, except those exempt from this article, and those regulated by § 250-15.6, Prohibitions, shall be fully or partially shielded ad required in Table A below.
(1)
"Fully shielded" shall mean that those fixtures shall be shielded in such a manner that light rays emitted by the fixture, either directly from the lamp or indirectly from the fixture, are projected below a horizontal plane running through the lowest point on the fixture where light is emitted.
(2)
"Partially shielded" shall mean that those fixtures shall be mounted in such a manner that the uppermost edge of the shield is below the plane center line of the light source (lamp), minimizing light above the horizontal.
B.
Low-pressure sodium. Low-pressure sodium lamps with shielding are strongly recommended for general use within the City of Socorro.
