Wal-Mart Goes Green

Saturday, July 18th, 2009

Last Wednesday, July 15, the Wal-Mart in Leavenworth, Kansas reopened its doors, becoming the first member of the U.S. Department of Energy’s (DOE) Retailer Energy Alliance (REA) to implement a parking lot supported by LED lighting, according to LEDs Magazine.

The LED lighting for the parking lot is based on specifications developed by the REA. The Wal-Mart Superstore is the one of 43 retailers engaged in a DOE program called the Net-Zero Commercial Building Initiative (CBI). According to the CBI web site: (more…)

LEDs Oust Fluorescent Tubes

Tuesday, July 7th, 2009

LED lighting is saying goodbye to the fluorescent tube, or at least, it’s about to. According to a California-based LED manufacturer, there’s a new fluorescent-replacement LED lighting product providing the equivalent light output of 24 to 32-watt fluorescent lamps, consuming less than a maximum of 19 watts and operating on a voltage range of 100 to 290 volts AC.

While conventional fluorescent lamps typically have a rated life in the range 8,000 to 24,000 hours, these LED lamps boast an operating life of 50,000 hours — 5.7 years of continuous light. The construction of a UV-resistant polycarbonate housing over the LED tube provides increased protection and shielding against many environmental effects, allowing them to be placed in locations where typical lights would be more vulnerable to the elements.

Where for art thou, LEDs?

Monday, June 29th, 2009

LEDs Magazine recently highlighted an interesting student project involving Shakespeare and LED lighting. Liverpool Hope University student Emma Armstrong took on the enormous task of attempting to recreate lighting conditions on a performing stage during Shakespeare’s era using modern lighting technology, that is, light-emitting diodes (LEDs).

Armstrong explains that “lighting” in Shakespeare’s day mainly consisted of tallow (pig fat) candles used in lanterns and chandeliers. Her objective, then, was to reproduce the range of color, light, and flame using only LEDs. A difficult and time-consuming task, to say the least.

Dubai: LED projects abound

Tuesday, March 10th, 2009

“Advanced LEDs Ltd. completes two prestigious projects in Dubai” headlines a recent article in LEDs Magazine. The first: the world’s largest shopping mall. The second: the world’s tallest man-made structure ever built (according to Advanced LEDs).

Boasting more than 1,200 stores, the Dubai Mall plays host to a number of world-class attractions including an aquarium, ice rink, cineplex, and a spectacular water feature that traverses all four levels of the mall. The fashion area of the mall features a catwalk amidst 70 signature shops. Above the catwalk, Advanced LEDs created a stunning focal fixture, lighting huge sails (red, green, blue) using 6.5 kW LED lighting from 76 specially-designed RGBW fittings.

LEDs Power Entire Island

Thursday, December 4th, 2008

Light-emitting diodes (LEDs) will be the exclusive source of artificial lighting on a small private island off the coast of Connecticut. As a result, the three-acre island will achieve net-zero energy, meaning its energy use will be negated by its energy generation.

The island, North Dumpling, is owned by Dean Kamen, a prolific and eccentric inventor, who decided to convert the island to LEDs when the US Coast Guard cut electrical connectivity to the island’s lighthouse.

Nichia Dedicated To Environmental Policy Benefits

Wednesday, March 19th, 2008

Over the past several years, a disturbing number of corporations have been slammed for their bad corporate and environmental practices. As people start to understand the benefits of going green, they become increasingly critical of companies that do not take the same care for our environment and the future of the world into their corporate culture.  There are companies that not only gain financially by developing environmentally friendly products, they also feel responsible for ensuring their corporate practices reflect a positive commitment to the earth.  Nichia is such a company.

Nichia, an LED lighting technology manufacturer, has taken it upon itself to post their Environmental Policy for the world to read and understand. By doing so, they show their customers that making money for them means making environmentally-friendly products through the appropriate corporate practices.

Cree Acquires LED Lighting Fixtures, Inc.

Monday, March 3rd, 2008

Respected LED manufacturer, Cree has signed an agreement to acquire LED Lighting Fixtures, Inc., a LED fixture manufacturer that has developed LED lighting retrofit products. This collaboration gives Cree a solid foothold in the LED market, from LED chip manufacturing to packaged LED fixtures.  The acquisition also puts Cree in competition with some of its existing LED customers, though industry experts say this is not uncommon. 

“The combination of Cree’s lighting-class LEDs and LLF’s lighting-systems technologies should set the stage for Cree to obsolete the light bulb, a 19th century invention that wastes energy and pollutes our environment,” said Cree CEO, Chuck Swoboda.
