| Modular design allows scores of fixture component combinations to meet installation and lighting needs and many most-used combinations are offered prewired and assembled, complete with lamp, packaged in a single carton and ready to install |
| Choice of heat-resistant prismatic glass refractors (NEMA distributions I, III and V), or heat-resistant prismatic glass globes for hazardous area fixtures |
| Colored and clear polycarbonate globes and Tuff-skin® coated glass globes are available but are NOT approved for use in classified areas |
| Fixtures with these globes do NOT comply with code requirements, and should be used in non-classified areas only |
| Globes and refractors thread directly into ballast housing |
| Mounting hoods include cone-shaped pendant hood, standard pendant, flexible pendant, ceiling and wall pendants (tapped for 3/4 in or 1 in NPT), 25 deg angle stanchion, and 90 deg (straight) stanchion (both tapped for 1-1/4 in or 1-1/2 in NPT) |
| Cone hood fixtures for pendant mounting shed dust, dirt and combustible fibers, cone hood inhibits build-up that "insulates" fixture and slows heat transfer, and provides increased surface area for more effective heat dissipation |
| Reflector choice includes standard dome and 30 deg 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 |
| For high corrosion resistance, fixture housing, mounting hoods and guards are copperfree cast aluminum with baked epoxy finish, electrostatically applied for uniformity, all exposed hardware is stainless steel |
| Hinge has high lip for added safety during installation and servicing |
| Body gaskets and globe gaskets are high temperature silicone rubber, capacitors are non-PCB type, thermally isolated from ballast |
| Mogul base porcelain socket with nickel plated contacts has 200 deg C (392 deg F) welded leads, prewired to the ballast, assures trouble-free operation in installations where high ambient temperatures are encountered |
| HPS ballasts are high power factor (min PF 90%) |
| For electrical protection, a ground wire is provided on each Mercmaster to bond hood and ballast housing |
| Copperfree cast aluminum (less than 4/10 of 1%) mounting hoods, ballast bodies and guards |
| Stainless steel, latch assemblies have stainless steel bolt and captive nut; reflectors and guards attach with stainless steel screws threading into stainless steel inserts exposed hardware, white polyester reflector |
| 5 hubs, four close up plugs |
| 3/4 in NPT hub |
| 60 Hz frequency |
