Mercmaster Jr.™Enclosed and Gasketed HPS Lighting Fixtures.
Applications
Inexpensive HID integrally ballasted fixture for use in hazardous locations – inexpensive to buy and inexpensive to operate (uses one-fifth as much electrical energy as incandescent and three quarters as much as fluorescent).
Enclosed and gasketed HID lighting fixtures for use in tunnels, walkways, bridges, storage facilities, processing plants, parking lots, foundries, manufacturing plants, power plants and other locations where moisture, dirt, dust or corrosive atmos­pheres are encountered.
Features
“Wireless” design. Threading of fixture unit onto mounting hood makes electrical connection. Only wiring required is attaching two wires to connection block in mounting hood.
Safe, easy servicing without disconnecting any wiring. “Wireless” fixture unit easily threads off mounting hood for convenient servicing.
Quick, easy conversion from Appleton V-51 incandescent installation to Mercmaster Jr. HID. Just remove V-51 fixture unit and thread Mercmaster Jr. fixture unit onto existing V-51 mounting hood.
