Custom 6-inch 1.25watt 3500K LED wall grazers light the stone surfaces. Special thanks go to: Beverly Hills fire chief Tim Scranton; Eric Sassower (owner, Advantage Light Source) for LED fixtures and making the custom shrouds; Marlene Miller (Total Lighting Concepts) for scarab fixtures (I-beam and flag pole); Hans Christensen (Sun Electric) for help with 120-volt electric; Emily Gorecki, lighting designer/adj. lighting prof., U. of New Haven, for tech. lighting descriptions. (Continued from page 56) Right Erected outside of the circular center in the nonmowable turf are the flame-waved basalt stone replicas of the Twin Towers built to scale. To take advantage of the stone���s rough texture, one 90-watt halogen PAR38 lamp was placed at the base of each vertical face to graze up the full 21-foot height, resulting in dramatic patterns of negative and positive space. placed at the base of each tower to graze the rough textured stone face, resulting in dramatic patterns of negative and positive space. The pathway along the entrances into the monument has six short basalt stone water features. Three submersible grade 2-watt 3500K LED uplights at the base of each column catch the play of the water. One entrance hosts the large 10-ft. linear stone donor wall, lit with custom 6-inch 1.25-watt 3500K LED wall grazers. The pathway concludes on either end of the memorial flanked with two additional granite benches continuing the same effect as the 10 benches along the main diameter of the steel artifact. Light Control All the fixtures on site, aside from those under the granite benches, were given custom shrouds to better shield and direct the light. A simple control system 58 Landscape Architect and Specifier News was designed to turn each element on and off, provide dimming capabilities, and an ���ease of use��� by city personnel working on the site. Documentation Design documentation incorporated fixture and lamp specifications, and control system groupings, along with individual coordination to the control panel. Record documentation displayed each transformer, mechanical timer and dimmer clearly labeled. Each dimmer switch position was marked on the panel at the desired levels for future uniformity. Relamping charts were laminated and permanently inside the control room. A lighting maintenance agreement was also provided to the city. All lighting maintenance is completed every six months by the designer.
