With the evolution of business management models over the last several decades, new planning philosophies for addressing workplace space issues have emerged. Concepts such as alternative officing, hoteling, desk sharing, or Just-In-Time (JIT) are becoming commonplace.
Quality of light and end-user safety are driving forces behind a trend to retrofit or install whiter lighting. Popular lighting choices include pulse-start metal halide lamps, ceramic metal halide lamps, and electrode-less induction lighting.
Over the years, motion sensor lighting has taken on many roles. At one point, they were used solely for security purposes. As people began to realize that different lighting levels help conserve energy, this became more of the focus.
Pulse-start metal halide ballast and lamp systems bring a wealth of benefits to users of high-intensity discharge (HID) lighting. Prior to the development of pulse-start systems, metal halide lighting delivered white light at the cost of operational inefficiencies.
The common cry heard these days from electrical contractors is, “We need to save energy costs.” With the blackouts in California, the increase in fuel prices, and the incentive for reduced energy usage, it is time to revisit the advantages of compact fluorescent lamps (CFLs) in downlighting applicat
As an electrical contractor, you may feel like you’re walking a tightrope when selecting and installing lighting systems for modern retail stores. You want to provide retailers’ desired look and feel while meeting their requirements for long life and operating efficiency within budget.
Having lit a large stuffed elephant in Wisconsin, and a three-story high wooden one in New Jersey, CLI was then called upon to light a resident goat in a full-scale reproduction of an 1100 B.C. Iron Age house in Canaan.
Glass fiber optics lighting is composed of three compatible parts. First-time users should consult with a qualified supplier to create a bill of materials. A light source: (called an illuminator or projector) is conveniently located in a readily accessible place for relamping.
Final results of a four-year landmark building lighting study by the National Association of Lighting Management Companies (NALMCO) provides a roadmap for achieving potential savings of 10 percent of the lighting costs or more––or from $2.7 billion to $3.6 billion in savings annually––for many build
For decades, lighting designers, specifiers, contractors, and distributors regarded halogen lamps as best-suited for outdoor applications or as accent and display lighting. Their bright, striated light caused “sparkle,” but was far too harsh for general lighting purposes.
Few things become less complicated over time. Lighting is no exception. More and more “other people” have something to say about the lighting you put in, and it is not enough to know the National Electrical Code (NEC) by chapter and verse.
