Osram LEDs to Light the Sistine Chapel’s Michelangelo Frescoes

LED-based lighting will enable higher illuminance levels on iconic artwork in famed Rome cathedral while preserving the historically-significant work and utilizing 60% less energy.

Osram’s lighting business has announced that it will be retrofitting the lighting in the Rome, Italy Sistine Chapel, using LED-based fixtures to highlight the Michelangelo frescoes. The project, involving custom-designed fixtures optimized for beam control and with a color spectrum that will highlight the pigmentation in the frescoes, will be completed next year, although a pilot project entitled LED4Art has already proven the concept.

Shine On, You Crazy Lightbulbs

The other day I found myself at a loss in the light bulb aisle of my hardware store. I might as well have been shopping for a carburetor. There were too many options with too many symbols and verbiage that I couldn’t decipher (LED, CFL, halogen, lumens, Kelvin, CRI), not to mention all of the various brands (GE, Philips, Cree, EcoSmart — each with its own packaging lingo). Since when do you need an electrical engineering degree to buy a light bulb?

Sports Teams Use of LEDs Highlighted

NHL franchise the Montreal Canadiens and MLB team the Seattle Mariners are two professional sports teams experimenting with LED lighting as a means of cutting their energy bills and adding flexibility to their lighting, reports The New York Times.

Bell CentreThe Canadiens’ home, the Bell Center, last year installed 140 LED fixtures to light its playing surface. The LEDs produce three times as much light per watt that the high intensity discharge lamp they replaced and will save the venue $125,000 a year in electricity bills, the paper reports.

LED Lights Cut Crime in Baltimore Parking Lot

Johns Hopkins School of Medicine is located in historic downtown Baltimore, Maryland, and is one of the most prestigious learning institutions in the country, but it is also in the midst of a crime wave that disturbs citizens and authorities alike. Since July of this year, there have been several incidents involving attacks and robberies near campus on employees traveling to and from transportation and parking lots. Several of these crimes involved the theft of cell phones that were grabbed from unsuspecting citizens. Police and campus authorities are recommending that pedestrians in the area remain aware of their surroundings at all times and not advertise that they have a cell phone in their possession in an effort to deter the criminals. The single most important tip they have for individuals is to stay in well-lit areas after dark. It is well known that adequate lighting is a major crime deterrent, so avoid dark places and isolated, shadowy areas.

Since manager installed lower-wattage, brighter burning LED lights in a parking lot near Johns Hopkins Hospital in Baltimore, residents report that crime in the lot (not shown), mostly theft, has dropped significantly.

Used As Intended, LED Lights Are Perfectly Safe

Early in the development of Light Emitting Diodes (LED), the rumor started that LEDs are bad for human eyes. Unfortunately, this misinformation continues to spread. Some people say that because some people claim to see a halo around a blue LED, this proves the theory. The reality is that there is no definitive proof that LEDs used properly routinely cause eye damage.

220px-Blue_light_emitting_diodes_over_a_proto-boardIt is true that LED light intensity is not standardized. It is true that some irresponsible writers have wrongly compared LED lights to looking directly at the sun. It is true that the industry monitors itself. It is true that staring directly at an LED is not a great idea. But, most importantly, it is true that there is no scientific proof that LED lights cause eye damage. Continue reading

Organic LEDs, The Next Generation of Office Lighting?

According to estimates from New York’s Research Development Authority (NYSERDA), about 40 percent of electricity in the US is consumed by office buildings. One upstate company, OLEDWorks, is developing technology that could help to lower this consumption.
