Features & Benefits

• Compact light weight low profile lighting design is suited for low mounting heights
• Modular design allows scores of fixture component combinations to meet installation needs. Uses same mounting hoods as Mercmaster III
• Fixture housing and mounting hoods are copperfree cast aluminum with baked epoxy finish. All exposed hardware is stainless steel
• Luminaire accommodates a wide range of voltages
• Ambient temperatures:
  • 70 W to 100 W equivalent: -40 °C to +65 °C (-40 °F to +149 °F)
  • 150 W to 175 W equivalent: -40 °C to +55 °C (-40 °F to +131 °F)
  • 250 W to 350 W equivalent: -40 °C to +50 °C (-40 °F to +122 °F)
  • 400 W equivalent: -40 °C to +55 °C (-40 °F to +131 °F)
• Electrical: 120-277 Vac, 50/60 Hz; 347-480 Vac, 50/60 Hz, Volts +/- 10%
• Pole terminal block: 1 x 8-24 AWG; 1 x 0.75 to 6 mm² (0.0012 to 0.0093 in²)
• Hinge has high lip for added safety during installation and servicing
• Hinge and bolt construction assures 360º compression at all points on ballast housing gasket for positive sealing. Swing away design of captive bolt and nut simplifies servicing
• All Mercmaster mounting hoods have provision for easy field installation of fuses in fixtures
• NPT and metric threads standard
• NEMA Type V light distribution is standard
  • Type V distribution is required is areas where sufficient, evenly distributed light is necessary. It produces a circular distribution that has the same intensity at all angles
• NEMA Type I light distribution is available as an option for select NEC/CEC certified fixtures
  • Type I distribution is the perfect lighting for walkways, Type I distribution is perfect for lighting walkways, catwalks or anyplace where a narrow beam of light is required
• For ATEX/IECEx rated fixtures, ballast bodies and mounting hoods must be purchased separately
