In lighting news…

As of July 1 this year, T12 fluorescent bulbs have begun to disappear, no longer being manufactured or imported into the US. This phase-out has been a long time coming, as T12s have been around for over 70 years now. By switching to newer technology like T5s or T8s, building owners will save nearly 50% of the energy they normally use each year! These new lamps are smaller in diameter, but can still provide the same light output as a T12. For those building owners who still have T12 fixtures, it will become increasingly difficult to find replacement parts. Check out this article from LampRecycling.com on strategizing for the phase-out.

Meanwhile, everyone is going nutso for LEDs. But with the impressive energy-saving stats and new innovations, we don’t blame them. According to IMS Research, the widespread implementation of retrofit LED lights will save us $100 billion globally over the next 5 years. To learn more, read this article from ECMWeb.com.

In June, at the Rio+20 U.N. development conference in Brazil, the Clean Revolution campaign began a trial in 12 major cities across the globe, testing the benefits and drawbacks of LED street lights. Each city has reduced energy use up to 85%! Continue reading »

PinExt The Saga of the LED

LED 300x269 The Saga of the LEDLEDs are everywhere. Over past years they’ve crept into our cell phone screens, the headlights on our cars, the display boards in our favorite sports stadiums, and even into our household light sockets.  With their minimal energy consumption and extra-long rated lives, these babies are on the rise. But in this heyday of LED innovation, have you ever wondered how they came about?

Disclaimer: the history of LEDs is crazy.

(But what would you expect for a light source that we use to light our streets at night AND zap the tattoos off our arms?)

In the beginning was Henry J. Round, a British experimenter at Marconi Labs. In 1907 he was unsuspectingly at work on a cat’s whisker detector for radio made with carborundum (SiC) when suddenly he witnessed a yellowish light—and lo! it was electroluminescence. With increased voltage the light turned brighter yellow, then green, orange, and finally blue. Round was so stoked he wrote a letter to Electrical World about it, and then went back to his radio.
