9/11 Memorial (Continued from page 54) Right Nineteen 5-watt 3500K LED up lights wash the landscaping around the memorial. Opposite the Towers and close to the curbside flies the American flag, uplit with three 90-watt halogen, 8-degree PAR38 lamps. Offset from the main focal point of the monument, the flag proved to be the third vertical element to give visual balance to the memorial. Above Ten curved granite benches surround the memorial planter, inviting visitors to sit and reflect on 9/11. A raceway was engraved into the underside of each bench to position additional 3500K LED linear strips. The custom strips are 11-ft. long and 27.5-watts. Metal clips hold the strip fixtures in place and lock the aiming angle to maximize the lighting on the granite walking path. back bending, made it difficult to produce the level of light to make the steel the focal point. It took several nighttime mock-ups with varying color temperature lamps and wattages before selecting the final lamp choice and luminaire count. The other major concern to the design was creating a visual lighting boundary between the memorial and the adjacent street and building lights. It also became necessary to define the custom granite pathways through nontraditional path lighting to avoid adding additional vertical elements to the space. Design Techniques Beginning from the center of the monument illuminating the steel artifact, the final design includes seven 90-watt halogen PAR38 up lights positioned and aimed to enhance the details of the steel beam. A 2700K color temperature was selected to give the 56 Landscape Architect and Specifier News desired warmth to the beam. On the outer edge of the planter are custom 6ft 15W, 3500K LED linear strip luminaires behind an acrylic opal lens. The strips are angled at 45-degrees to allow people to read the 2,977 names engraved onto the dark gray stone face. The strips also shed light on the walking path around the planter. Around the pentagonal planter stand 10 curved granite benches to let visitors reflect upon the memorial. Raceways engraved into the underside of each bench allows custom 11-ft. 27.5-watt, 3500K LED linear strip fixtures to be attached and angled at 45-degrees. Metal clips hold the strip fixtures in place, and lock the aiming angle to maximize the light on the granite-walking path surrounding the planter. Erected outside of the circular center in the nonmowable turf are the two Twin Tower flame-waved basalt stone replicas. One 90-watt halogen PAR38 lamp was (Continued on page 58)
