1. BACKGROUND

The existing exterior lights were installed to provide security for San Cristobal. Their operation has a major impact on the park’s electricity bills. The park is seeking to reduce the cost of operating external lights by replacing them with long-life energy-efficient LED luminaires.

2. OBJECTIVES:

Replace existing exterior lights with energy efficient lighting fixtures, while minimizing light spillage and enabling color changing for special events.

Purpose of exterior lighting is for decoration and security.

3. PLACE OF PERFORMANCE:

El Castillo San Cristobal is a large masonry Fort on the northeast side of San Juan Island in Puerto Rico.

Work days and hours: 7:00am to 3:00pm Monday through Friday, excluding Federal Holidays.

Access to jobsite and electrical panels will be gained through the Contracting Officer Representative (COR) and/or park maintenance staff.

4. PERIOD OF PERFORMANCE:

Period of performance is 120 calendar days from issuance of Notice to Proceed.

5. SCOPE:

This project is to remove existing exterior lighting and replace with long-life energy-efficient LED luminaires.

*See Appendix A PDF file for example photos of actually installed fixtures.

Add control system for the new color-tunable luminaires; existing electrical wiring to luminaires shall be retained, and no new control wiring may be run to luminaires.

Install new concrete support bases for each pedestal-mounted floodlight per manufacturer recommendations. Match the height of the existing lighting.

Properly dispose of existing light fixtures and concrete bases and any other debris or trash generated on this project.

6. SPECIFICATIONS FOR ALL LUMINAIRES:

Light housings shall be metal, either stainless steel or aluminum. Lighting shall sustain wind loads from hurricanes. All fasteners (bolts, anchors, washers, etc.) shall be stainless steel.

Luminaires shall be tamper-proof and listed or certified for wet locations by a U.S. Occupational Safety Health Administration (OSHA) Nationally Recognized Testing Laboratory (NRTL).

Luminaires shall accept 60 Hz single-phase 120 V electric service and operate normally with input voltage fluctuations consistent with NEMA SSL 1-2010.

Except where noted, luminaire shall have light output of electronically tunable color, and be capable of both of the following operating modes:

A. Warm white light, with a nominal correlated color temperature (CCT) value that is ≤ 3000 K, measured CCT and Duv values within ANSI C78.377-2017 tolerances for the nominal CCT value, and color rendering index (CRI) of ≥ 65.

B. Tunable (i.e., selectable or changeable) color. Luminaire shall be capable of producing any of a wide variety of saturated colors (e.g., blue or pink) for holidays and other special occasions.

Control of color-tunable luminaires must be wireless (e.g., Bluetooth or wireless DMX) or utilize existing electrical wiring (i.e., powerline carrier). No new wiring may be run to luminaires.

Luminaire light output shall not exhibit flicker exceeding the low-risk limits in Figure 18 of IEEE Standard 1789-2015. Specifically, the quotient of percent flicker (i.e., modulation depth) and flicker frequency shall be < 0.08 at flicker frequencies ≥ 90 Hz, and the quotient percent flicker / flicker frequency shall be < 0.025 at flicker frequencies < 90 Hz.

Combined illumination from in-ground and pedestal-mounted luminaires shall provide an average illuminance of ≥ 3.0 footcandles (fc, or lumens per square foot) on each of the seven illuminated wall segments when operating in warm-white mode, measured perpendicular to wall surface (i.e., with back of typical illuminance meter pressed to wall), with average-to-minimum uniformity ratio of ≤ 3:1. Calculation grid points shall be spaced 4 feet apart on each 32-foot height wall sloped 15 degrees away from luminaires (8 horizontal rows of points spaced 4 feet apart horizontally, centered on each wall segment). Luminaire locations are as shown in plan; in-ground luminaires are spaced approximately 18 feet apart and setback 2 feet from wall, on average.

Luminaires shall be selected with appropriate optical control to minimize light spillage.

Lumen maintenance for warm white light mode at 60,000 hours operation shall be ≥ 85% of initial, supported by IES TM-21 calculations based on IES LM-80 data and in-situ temperature measurement (ISTMT) testing, in accordance with the Design Lights Consortium methodology.

Luminaires shall have a minimum warranty of 5 years.

The new lighting will be differentiated from the old (historic lighting) and will be compatible with the historic materials, features, size, scale and proportion, and massing to protect the integrity of the property and its environment.

7. SPECIFICATIONS FOR IN-GROUND LUMINAIRES:

Luminaire shall allow for replacement of LED light engine (or LED light source and driver) in luminaire without excavation.

Luminaire shall have a minimum ingress protection (IP) rating of 68, as defined in IEC 60529.

If luminaire intensity distribution is circular (i.e., X° beam) or oval (i.e., X° by Y° beam) in cross-section, luminaire must have minimum 10° internal tilt capability, and minimum initial light output is 700 lumens. If the intensity distribution is instead of asymmetric design to wash or graze walls (i.e., does not exhibit quadrilateral symmetry) and lumens in quarter-sphere oriented toward wall are at least four times (4x) lumens in quarter-sphere oriented away from wall, then no tilt mechanism is required and minimum initial light output is 350 lumens. Resulting accent on wall shall have a natural “scallop” appearance with gradual fade from point of maximum illuminance, demonstrated via computer-generated grayscale rendering subject to COR approval.
