P.R. Laws tit. 12, § 8036a
The public policy of the Government of Puerto Rico relating to public lighting on roads, streets, expressways, and sidewalks shall be, henceforth, geared towards the policy of providing effective, adequate, and efficient lighting while avoiding excessive lighting. No public funds shall be used to install or replace outdoor public luminaires, unless:
(a) The luminaire is designed for energy efficiency while minimizing light pollution, glare and light trespassing;
(b) The illuminance level, measured in footcandles, of the surface that is to be lit shall be the minimum necessary that is adequate for the intended purpose, as is provided by the LEED instruments of the U.S. Green Building Council, which is based on the ASHRAE/IESNA 90.1 standard;
(c) The following standards are established for all public luminaires in the Special Class and Class 1 areas identified in § 8036 of this title:
(1) Unless security reasons do not allow it, the illuminance level on any road surface shall be one fourth (1/4) of the average design values as is established by the IESNA, or zero point six (0.6) foot-candles, whichever is the lowest.
(2) .....
(3) Any public luminaire that can be seen from a bay, beach, or lagoon shall have its uplight cut-off at 70 0 (seventy degrees) from its vertical axis, and shall be oriented (directed) in such a way that it cannot be perceived from the center of the classes, or from the coast. An exception shall be made when security reasons arise. In such cases,
(4) Luminaires for existing sports parks located within the class zones shall use full cutoff visors which direct light and eliminate glare and uplight. In the case of new parks, the lighting shall be directed towards the play area and cannot penetrate an area greater than ten (10) meters outside of the same, or emit light beyond a 90 0 angle, measured from its vertical axis (0 0).
(5) Incandescent, metal-halide, or mercury vapor lamps shall not be used.
