Performance Data <br />Lumen Output <br />Lumen values are from photometric tests performed in accordance with IESNA LM-79-08. Data is considered to be representative <br />of the configurations shown, within the tolerances allowed by Lighting Facts. Actual wattage may differ by +/- 8% when operating <br />between 120-480V +/- 10%. Actual performance may differ as a result of end -user environment and application. <br />Light <br />Engines <br />Drive <br />Current <br />(mA) <br />Performance <br />Package <br />System <br />Watts <br />(MVOLT') <br />Dist. <br />Type <br />40K <br />(4000K, 70 CRI) <br />Nominal <br />Lumens <br />LPW <br />1 <br />(10 LEDs) <br />2 <br />(20 LEDs) <br />SR2 <br />700 10A700/-K 24W SR3 <br />SR4 <br />SR2 <br />700 10A700/-K 47W SR3 <br />SR4 <br />1 See electrical load chart for 347/480V system watts. <br />Photometric Diagrams <br />2,005 <br />2,029 <br />1,959 <br />3,944 <br />4,028 <br />3,851 <br />84 <br />84 <br />Lumen Ambient Temperature (LAT) Multipliers <br />Use these factors to determine relative lumen output for average ambient temperatures <br />from 0-40°C (32-104°F). <br />0PC <br />10°C <br />20°C <br />25°C <br />30°C <br />40°C <br />Ambient <br />32°F <br />50°F <br />68°F <br />77°F <br />86°F <br />104°F <br />1.10 <br />1.06 <br />1.02 <br />1.00 <br />0.98 <br />0.92 <br />82 <br />64 Projected LED Lumen Maintenance <br />86 Data references the extrapolated performance projections for the WST LED 2 10A700 <br />82 platform in a 25°C ambient, based on 10,000 hours of LED testing (tested per IESNA LM- <br />80-08 and projected per IESNATM-21-11). <br />To calculate LLF, use the lumen maintenance factor that corresponds to the desired number <br />of operating hours below.

The long life LEDs and driver make this <br />luminaire nearly maintenance -free. <br />CONSTRUCTION <br />The single -piece die-cast aluminum housing integrates secondary heat sinks to optimize thermal <br />transfer from the internal light engine heat sinks and promote long life. The driver is mounted in <br />direct contact with the casting for a low operating temperature and long life. The die-cast door <br />frame is fully gasketed with a one-piece solid silicone gasket to keep out moisture and dust, <br />providing an IP65 rating for the luminaire. <br />FINISH <br />Exterior parts are protected by a zinc -infused Super Durable TGIC thermoset powder coat finish <br />that provides superior resistance to corrosion and weathering. A tightly controlled multi -stage <br />process ensures a minimum 3 mils thickness for a finish that can withstand extreme climate <br />changes without cracking or peeling. Standard Super Durable colors include dark bronze, black, <br />natural aluminum, sandstone and white Available in textured and non -textured finishes <br />OPTICS <br />Precision -molded acrylic lenses are engineered for superior distribution, uniformity, and spacing <br />in wall -mount applications. Light engines are 4000K (70 CRI). The WST LED has zero uplight and <br />qualifies as a Nighttime Friendly•' product, meaning it is consistent with the LEEDC and Green <br />Globes •' criteria for eliminating wasteful uplight. <br />Distribution overlay comparison to 175W metal halide. <br />LEGEND <br />■ WST <br />LED, <br />0.5 fc <br />■ WST <br />HID, <br />0.5 fc <br />10' W Sidewalk <br />LLDs: <br />WST HID = 0.72 <br />WST LED = 0.95 <br />WST HID: <br />213W <br />WST LED: <br />47W <br />WST LED 210A70040K SR4, <br />WST 175M FT Probe, 12' Mounting Ht <br />ELECTRICAL <br />Light engine(s) consist of 10 high -efficacy LEDs mounted to a metal core circuit board and <br />integral aluminum heat sinks to maximize heat dissipation and promote long life (100,000 <br />hrs at 25°C, L77). Class 2 electronic driver has a power factor >90%, THD <20%. Easily - <br />serviceable surge protection device meets a minimum Category B (per ANSI/IEEE C62.41.2). <br />INSTALLATION <br />A universal mounting plate with integral mounting support arms allows the fixture to hinge <br />down for easy access while making wiring connections. The integral bubble level on the <br />mounting plate provides assistance for level placement on every installation. <br />LISTINGS <br />CSA certified to U S and Canadian standards Light engines are IP66 rated, luminaire is IP65 <br />rated and suitable for wet locations when mounted with the lenses down. WLU option offers <br />wet location listing in "up"orientation. Rated for -30°C minimum ambient. <br />DesignLights Consortium° (DLC) qualified product.
