Industrial lighting varies widely by environment and application. Workplaces range from control room to laboratory to warehouse. Each has its own lighting requirements.

The industrial workplace environment is divided into two general categories-low bay and high bay. Areas where the luminaire is less than 20-ft above the floor are considered low bay, while areas where the luminaire is more than 20-ft above the floor are high bay. Low bay fixtures should spread light and reduce glare, while high bay units should concentrate light with a medium spread and prominent downward light component.

Luminance- also called brightness-is light emitted from a surface. It is measured in candelas per square meter. Luminance levels should be kept uniform to prevent worker eyestrain and fatigue, which could affect productivity. Also, accidents could occur when moving between areas not uniformly illuminated.

Lumen output of a lamp at approximately 100 hr of operation is known as initial lumens. The output of a lamp after it has operated for approximately 40% of its rated life is known as mean lumens.

Color temperature describes the appearance of the lamp source measured in deg Kelvin. High numbers are considered cool and blue in appearance. Low numbers are warm and red/yellow in appearance.

Color rendering index (CRI) measures on a scale of 1-100 how accurately colors appear under a certain source. The most accurate rendering is 100.

Lamp efficacy is measured in lumens per Watt and is the efficiency of the lamp. Like miles per gallon, the higher the number, the better the energy efficiency.

Ballasts

Arc discharge lamps, such as HID and fluorescent, require ballasts to establish the arc and maintain electrical current once the arc is struck. Ballasts also compensate for voltage variations.

Magnetic and electronic ballasts are available for fluorescent lighting systems. Ongoing developments in both lamps and ballasts are improving their efficiencies and extending their lives. Both translate to cost reductions in your plant.

                                                              Ballast regulation. Ability of a ballast to control lamp wattage, and therefore lamp output, when subjected to changes in line voltage.

                                                              Dip tolerance. Amount of line voltage drop a ballast can sustain before the lamp extinguishes. Usually expressed as a percentage; the higher the percentage, the better.

                                                              Ballast losses. Amount of additional energy a ballast consumes to operate the lamp (line Watts minus lamp Watts). There is usually a tradeoff between ballast losses and ballast regulation.

                                                              Constant wattage autotransformer (CWA). Lead-type regulator and the most widely used HID ballast. It offers good ballast regulation and moderate ballast losses. CWA is available for metal halide and high-pressure sodium lamps.

                                                              SCWA. Pulse-start version of the CWA ballast, but with greater lumen capabilities. Use on pulse-start metal halide lamps only.

                                                              LLRPSL. Low loss reactor used in areas with very little line voltage regulation. They are designed as an energy saving system. Use on pulse-start metal halide lamps only.

                                                              RLB. Regulated lag ballast (LAG-type regulator, "reg-lag") used in areas where line dip tolerance is critical. It exhibits the best ballast regulation. Use on pulse-start metal halide lamps only.

                                                              MRB. Magnetic regulated ballast referred to as a regulated or stabilized type, has operating characteristics similar to the RLB. Use on high-pressure sodium sources only.

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
