GENERAL: Each Gardco Square Form Ten arm mount is a sharp cutoff luminaire for high intensity discharge lamps. Units are designed with half -cube proportions. Internal components are totally enclosed, rain -tight, dust -tight and corrosion resistant. No venting of optical system or electrical components is required or permitted. Luminaires are completely assembled with no disassembly required for installation. Lambing requires no lifting or hinging of the luminaire housing, disturbing wiring or exposing uninsulated live parts. HOUSING: Extruded housings (EH style) are offered in 14" and 19" sizes and are composed of precisely mitered anodized aluminum extrusions. Fabricated (H style) units are available in 14", 19", T19" and 26" sizes and are one piece, mufti -formed aluminum with an integral reinforcing spline and a single concealed joint. All units feature a press formed aluminum top which is welded to the housing sides. Pressure injected silicone provides a continuous weathertight seal at all miters and points of material transition. ARM: Extruded aluminum arm is prewired and secured to fixture by contractor. Assembly is suitable for mounting to pole without requiring access to luminaire. LENS: Mitered, extruded anodized aluminum door frame retains the optically clear, heat and impact resistant tempered flat glass in a sealed manner using hollow section, high compliance, memory retentive extruded silicone rubber. Luminaires with Type 4X optics and 26" VS units feature a sag glass lens and VS unit employs sag acrylic lens. Concealed stainless steel latch and hinge permit easy toolless access to the luminaire. OPTICAL SYSTEMS: The segmented Form Ten optical system is homogeneous sheet aluminum, electrochemically brightened, anodized and sealed. The segmented reflectors are set in faceted are tube image duplicator patterns to achieve IES Types 1 (1), III (3), IV (FM), and V (Q - horizontal lamp and VS - vertical lamp) distributions. The mogul Iampholder is glazed porcelain with a nickel plated screw shell with lamp grip - all securely attached to the reflector assembly. 100MH units have medium base Iampholder. All Metal Halide units in the 19" and 26" housings have lamp stabilizers ensuring precise arc tube positioning. ELECTRICAL: Each high power factor ballast is the separate component type, capable of providing reliable lamp starting down to - 200 F. The ballast is mounted on a unitized tray and secured within the luminaire, above the reflector system. Component -to -component wiring within the luminaire will carry no more than 80% of rated current and is listed by UL for use at 600 VAC at 1500C or higher. Plug disconnects are listed by UL for use at 600 vAG, 1 bA or nigher. FINISH: Extruded housings (EH style) are standard with bronze, or black Aluminum Association Architectural Class I finish. Special color polyester finishes are available. Formed housings (H style) are standard with a chromatic acid pretreatment and an epoxy undercoat. The finish coat is a thermosetting polyester baked at 450' F to achieve an H-21-1 hardness measure. 26" H style units are also offered with optional Architectural Class I anodized finish. I LABELS: All fixtures bear UL or CUL (where applicable) Wet labels.
