Lamp Life (La vita è bella)"
Article in Lighting Futures by Lighting Research Center By John D. Bullough : It\'s not likely that Roberto Benigni will ever make any feature films extolling the virtues of long-life lamps and lighting systems. However, many in the lighting industry recently have been more than willing to discuss this aspect of lighting, and it appears that many more will do so in the future. A growing sophistication about the economics of lighting has emerged, and with it, so has an understanding that luminous efficacy, or lumens per watt, is not the only important variable in designing and maintaining cost-effective, quality lighting.

Lamp Life: Seeing the Light by James C. Piper
One of the most important factors in managing a facility's lighting program is the life of the lamps used. Longer lamp lives result in replacing the lamps less frequently, reducing both labor and lamp costs. But the concept of lamp life is frequently ...

LEDs : From Indicators to Illumination
Article in Lighting Futures, Lighting Research Center By Andrew Bierman : Nearly everyone is familiar with LEDs (light-emitting diodes) from their use as indicator lights and numeric displays on consumer electronic devices. The low light output of LEDs and a lack of color options have limited LED technology to these uses. Now, however, new LED materials and improved production processes have resulted in bright LEDs in colors throughout the visible spectrum with efficacies greater than incandescent lamps. These brighter, more efficacious, and colorful LEDs may move LED technology into a range of lighting applications. The energy-savings potential is enormous. By one estimate, replacing only the incandescent traffic signals in the United States alone with LED signals would save nearly 2.5 billion kilowatt hours annually

The Lamp Disposal Controversy
Article in Lighting Futures, Lighting Research Center In 1994, the United States Environmental Protection Agency (U.S. EPA) proposed changes to current federal lamp disposal regulations, setting off an intense, ongoing debate between lamp manufacturers, recyclers, lighting services companies, state and local government agencies, and environmental advocates. All have much at stake, as do companies that have committed to major lighting upgrades that will generate large quantities of spent lamps for disposal.
