The perceived quality of a lighted space is greatly affected by the color consistency within the space; therefore, the consistency of individual luminaires’ output is crucial. That’s where MacAdam ellipses play a role. Today, experiments conducted by physicist and color scientist David MacAdam in the first half of the 20th century help us understand the perception…
Morning fog and afternoon showers are common during spring months. Navigating roadways during these low-visibility conditions can be difficult for drivers and pedestrians, but modern LED roadway lighting technology is making spring commutes safer for motorists.
Streets, roadways, parking lots and pedestrian areas are only a few examples of outdoor areas that rely on superior lighting design for safety and efficiency. LED lighting is rapidly becoming a strong competitor to high-intensity discharge (HID) light sources for outdoor lighting. Kenneth Siderius, Invue marketing manager with Eaton’s Lighting Division, talked with us about…
Picture yourself at a baseball game. Snack in hand, you settle into your seat with a snack and wait for the first pitch. What time of day is it? Did you picture the sky darkening over the field just before sunset? Today, more than 80 percent of Major League Baseball (MLB) games are played at…
Cities everywhere are discovering the advantages of LED technology for roadway lighting. LED roadway lighting can provide tremendous community benefits for pedestrians, drivers and even local governments. But how can cities determine the best correlated color temperature (CCT) for their roadway lighting? Eaton’s Lighting Division spoke with Bob Ebbert, LC, Streetworks LED sales project manager,…
Couples driving to dinner parties, neighborhood kids trick-or-treating, workers safely walking to their cars after a long day at the office: these are all activities made possible by outdoor lighting technology. Throughout the 20th century, inventors and innovators developed new technologies to light our streets more effectively and create a safer, more productive society.
Imagine a world where many of the typical devices in a space have evolved to be able to gather data, share data, and connect to and communicate with people and other devices in real time, turning the everyday physical world into one massive information system. Internet connectivity is no longer limited to computers or smartphones…
Scott Rosenfeld, LC, IESNA, is a lighting designer at the Smithsonian American Art Museum, part of the world’s largest research and museum complex located in Washington, D.C. The museum is home to one of the largest and most inclusive collections of American art. “Museums really care about lighting design, and they build the necessary infrastructure…
Today, the word “city” conjures images of skyscrapers, bright lights and bustling crowds that never rest. But cities didn’t begin to develop into the lively places we know today until the second half of the 19th century. Along the way, lighting technology and other innovations accelerated the urbanization process. Thomas Edison’s carbon-filament incandescent bulb, or…
