Standard Materials and Finishes
Mounting hoods, bodies and guards are cast copperfree (4/10 of 1% max.) aluminum with electrostatically applied baked gray epoxy-clad finish. Globes are heat-resistant prismatic glass; reflectors are FRP with a polyester finish. Hardware, catch assemblies, guard are stainless steel
Optional Photocell
A photocell to provide automatic "on-off" control is available as an option for all fixtures except those with cone or ceiling mounts

Features

  • Typical applications include pulp and paper mills, processing plants, chemical plants, oil refineries, foundries, manufacturing plants, storage areas and marine applications
  • These medium base lamps accommodate 50 to 150 Watt high pressure sodium (HPS) or 70 to 250 Watt metal halide (MH) lamps. There is a wide range of voltages and ballast types available
  • A choice of heat-resistant prismatic glass refractors (NEMA II or V) or heat-resistant globes are available. They thread directly into the ballast housing and seal against a high-temperature silicone rubber gasket
  • Modular design allows scores of fixture component combinations to meet installation and lighting needs. Mounting hoods include cone-shaped pendant, standard pendant, flexible pendant, ceiling and wall (tapped for 3/4" or 1" NPT), 25° angle stanchion and straight stanchion (both tapped for 1-1/4" or 1-1/2" NPT). Cone hood fixtures for pendant mounting shed dust, dirt and combustible fibers, and inhibit build-up that "insulates" fixture and slows heat transfer. Also provide increased surface area for more effective heat dissipation
  • Reflector choice includes standard dome and 30° angle types, both made of fiberglass reinforced white polyester; highly resistant to unusually corrosive applications. Reflectors are vented for cooler, dirt-free operation and maintained lumen output. They secure to ballast housing with stainless steel screws threading into stainless steel inserts
  • Hinge has high lip for added safety during installation and servicing. Hinge and bolt construction assures 360° compression at all points on ballast housing gasket for positive sealing. Swing-away design of captive bolt and nut simplifies servicing
  • Body gaskets and globe gaskets are high-temperature silicone rubber
  • All Mercmaster III mounting hoods have provision for easy field installation of fuses in fixtures (see fuse kit listings on catalog pages)
  • Guards are available to protect globes from damage. Keyhole slots allow easy installation and are secured with stainless steel screws
  • A restricted breathing (AEx nR) option is available making the Mercmaster III an ideal HID luminaire for use in Zone 2 locations
  • For electrical protection, a ground wire is provided on each Mercmaster to bond hood and ballast housing
