The streets of Fayetteville will be brighter and more efficient by this time next year. As part of a pilot study by the Public Works Commission, the city-owned utility plans to convert 300 streetlights to LED. Light emitting diode technology lasts three times as long, and uses about half the electricity of sodium-vapor powered lights, […]

  Intelligent lighting control systems are gaining popularity thanks to the falling cost of light emitting diodes (LEDs) for commercial buildings. "Falling prices are triggering re-lamping projects in many existing commercial buildings. Because LEDs are particularly well-suited to digital control, many existing commercial building owners will decide to incorporate additional lighting intelligence - including photosensors, […]

Light emitting diodes (LED) technology has grown to rival the most efficient white light sources, and the benefits are great, but just how efficient are LEDs? First measure is color quality. LEDs have very high correlated color temperatures (CCTs), often above 5000K for a cold bluish light. However, warm white LEDs (2600K to 3500K) have improved […]

The famous Golden Gate Bridge may get an LED makeover. As part of its Gateway program, the Department of Energy has evaluated the use of LED retrofit kits to replace the existing lights on the San Francisco landmark. “The goal of the study was to identify solutions to reduce maintenance and energy use without compromising […]

This is the final post in a series about lighting maintenance.   The first and second part of this series on lighting maintenance covered the principles and policy that should be placed for an efficient system.   Providing proper training should also be included in a lighting maintenance plan. This includes understanding procedures such as […]

This is the second in a series of posts about lighting maintenance. In the first part of this blog series, the principles of lighting maintenance were discussed as a proactive solution to reducing energy usage. The second part of proper lighting maintenance is developing a policy. A lighting maintenance policy is a set of written procedures […]

This is the first in a series of posts about lighting maintenance. According to the U.S. Department of Energy, lighting accounts for an estimated 20 percent of the total energy used in commercial buildings. More often than not, many buildings do not have a detailed lighting maintenance policy other than replacing burned-out bulbs. Poor lighting […]

Ideal for property managers or high-usage buildings, intelligent lighting controls offer more versatility and opportunities to save on utility bills. Intelligent lighting controls are lighting systems that can be controlled centrally, giving facility managers a better way to monitor and control lighting. In most systems, fixtures in a room can communicate wirelessly with each other, […]

A recent survey found that 95 percent of cities and municipalities in the United States that have implemented LED streetlight projects were satisfied with the overall performance of the streetlights. Northeast Group, a Washington D.C.-based research firm, surveyed nearly 100 cities and municipalities across the U.S. that have implemented some form of LED streetlight initiatives. […]
