Philips is ringing in Earth Day (Wednesday, April 22) a bit early with the launch of a 60-watt LED bulb it says is the most affordable of its kind. It’s not the only product the company announced today, though. It’s part of a troika that constitutes the Dutch lighting giant’s new LED A19 product range.

VATICAN CITY—In the 500 or so years since the Sistine Chapel was decorated, it has never looked so good. That’s in part because no one has ever seen Michelangelo’s frescoes portraying the book of Genesis and “The Last Judgment” in quite the right light. Now, with the help of 7,000 light-emitting diodes or LEDs, the detailed work has emerged from the shadows.
The new lighting system was unveiled last week to commemorate the 20thanniversary of the chapel’s restoration and the 450th anniversary of Michelangelo’s death. The lighting project, together with a new climate control system, cost nearly $4 million, paid in part by funds from the European Union through a consortium called Led4Art, led by German light bulb giant Osram, which developed a special color temperature to best enhance Michelangelo’s hues at around 3,550 Kelvin units, according to the Osram explainer on the magical illumination. The rest of the work was donated either in supplies, expertise, or technology by firms who wanted to be involved in the project, meaning the Vatican didn’t have to spend any resources for the extraordinary enhancement.
As a bonus, the new lighting will use 90 percent less electricity, and is expected to lower the Vatican’s energy bill for the chapel by around 60 percent now that the standard ultraviolet light bulbs have been scrapped. The older UV bulbs, which proved damaging to the artwork, were introduced in 1980 when the chapel’s original windows were boarded over as part of a restoration project that took 14 years.
Found in smartphones, computer screens and energy-efficient bulbs, blue light-emitting diodes (LEDs) are everywhere. That they have now earned three Japanese-born inventors the 2014 Nobel Prize in Physics is a rare example of the award being given for a practical invention.
Torraca is a small village of 1,200 people in Italy. It is also the first place in the world to be totally illuminated by light-emitting diodes (LEDs). Representing a sea change, much like when electric lamps first graced London’s Holborn Viaduct back in 1878, some 700 streetlights (each containing 54 LEDS) now line Torraca’s arteries—and locales around the world, from Beijing’s Bird’s Nest Olympic Stadium to the Raleigh Convention Center’s Shimmer Wall in North Carolina, have begun to use LEDs to light up the night.
When maintenance and engineering managers with institutional and commercial facilities seek to upgrade their outdoor lighting, they are more often turning to LEDs. Staples Inc., the office supply retail giant, followed that script in 2011 when it sought to curb energy use at its corporate headquarters, a 650,000-square-foot building in Framingham, Mass.
Ed Ebrahimian loves to stare out the plane window on night flights home to Los Angeles. Next time you fly into L.A. late, take a good look and see why. Five years ago a bright orange blanket of light used to saturate the city and stain the air above. Today it’s a metropolis aglow with tens of thousands of cool silvery pinpoint lights. The grid is clearer. The skies are blacker.
When the news broke Tuesday that three scientists whose discoveries made practical household LED lighting possible had won the Nobel Prize in physics, most Americans probably thought of the LED screen in their TV, or perhaps about whether they might finally consider shifting to energy-efficient LED lighting in their homes. (The LED, or light-emitting diode, makes use of treated or coated semiconductors to produce light. Blue LED lighting — the Nobelists’ invention — was the missing ingredient that allowed the creation of LED lamps.)
- Taiwanese supply chain firms talking to Digitimes expect the total value of LED lighting output to rise 30% next year, with a doubling of shipments more than offsetting 30%-35% price drops. Research firm LEDinside expects shipment value to grow to $25.7B, or 31.3% of total lighting shipment value.
Property owners who want to upgrade their outdoor lighting now have an inside track to more energy-efficient lighting technology with the GE Evolve™ LED N Series fixtures. The new LED area lights, flood lights and wall packs make it easier to optimize space for visibility and operational savings while creating a consistent and contemporary look.

Tonight, the National Park Foundation, the official charity of America’s national parks, the National Park Service, and GE Lighting will unveil this year’s holiday LED lighting design for the National Christmas Tree at the 92nd annual National Christmas Tree Lighting ceremony at President’s Park. With more than 60,000 holiday LED lights on the living Colorado blue spruce, it is one of the most notable holiday displays in the United States.
