Where Did the Phrase “Go Green” Come From?

Go Green?

“Going green” has come to symbolize environmentalism in such a familiar way that most of us don’t think twice about who first coined the phrase.

I was curious about the origin of the term and wondered what made it take such strong hold in the English language. Speaking of curiosities, remember Heinz’s food flop several years ago when they decided to go green (literally) with ketchup? Glad that didn’t take hold.

Most people associate the beginning of the green movement and environmentalism with the publication of Silent Spring by Rachel Carson in the 1970’s.

Surprisingly, it dates back even further, to Henry David Thoreau’s writings in the 19th century. Thoreau spoke about living a “green” life in The Maine Woods in his call for conservation, forest preservation and respect for nature. You are probably familiar with several of Thoreau’s famous inspirational quotes (i.e., “Go confidently in the direction of your dreams,” or “What lies behind us and what lies ahead of us are tiny matters compared to what lies within us”). His greener remarks include:

What is the use of a house if you don’t have a decent planet to put it on?

This one’s my favorite (Thoreau, you were a funny guy!):

Beware of all enterprises that require a new set of clothes.

Did you have any idea the U.S. “green movement” was rooted in early American philosophy?

The Biggest Impact of the EISA Is Here: Bye-Bye 60-Watt Incandescent

CFL light bulb saves money

It has taken 7 years but we are now here. On January 1, 2014 both the 60-watt and 40-watt incandescent light bulb will no longer be produced as a result of the Energy Independence and Security Act of 2007 (EISA) signed by President George W. Bush. In years past we have lost the 100-watt and 75-watt. However, this next phase will probably have the biggest impact. Why? Simple. The 60 and 40-watt light bulbs are the most popular. According to Residential Lighting, they represent over 50% of all light bulbs used today.

We have been covering the incandescent phase out on this blog for the last couple of years. However, as a reminder, a primary goal of this law is to raise appliance and lighting efficiency standards.

The 60 and 40-watt light bulbs will not just vanish into thin air on January 1, 2014. You will probably still see them in stores for a couple of months. The key is that as of 1/1/14 they can no longer be imported into or manufactured in the United States. (more…)

A Friendly Glowstick Competition

Is there a better way to kick off a lighting design awards show than to distribute glowsticks to the finalists for “experimentation”?

Well, we can’t think of one.

The photos below have been floating around on Twitter in anticipation of the 2014 Lighting Design Awards, a worldwide architectural lighting competition to be held in London on March 20. Leave it to the creative lighting professionals to craft a rainbow motif, an “alien landing” scene, and a dog collar – all from a box of glowsticks.

NBC’s Rockefeller Center Tree Lighting

Tonight from 8-9 p.m. ET, NBC will air the live broadcast of the Rockefeller Center holiday tree lighting! We are excited to tune in. A few fun facts about this year’s tree:

  • This year’s Norway Spruce is 76 feet tall and 47 feet in diameter.
  • The tree was donated by a family in Shelton, Connecticut – it grew in their front yard for 20+ years.
  • 45,000+ LED lights were strung to decorate the tree.
  • A 9.5 foot wide LED-lit Swarovski crystal star tops the tree.

The show will feature performances from Mary J. Blige, Toni Braxton, Mariah Carey, Kelly Clarkson, Goo Goo Dolls, Kenny “Babyface” Edmonds, Ariana Grande, and Jewel. Check out the size of that tree!

Are Light Bulbs Taking Over the Internet?

We wrote an article a few years ago about “li-fi,” an up-and-coming technology that uses light bulbs to transmit a wireless signal. This technology has come a long way since then, and today it’s one of the craziest (and coolest) innovations in the lighting industry! Scientists across the globe (primarily in the UK and China) have been developing this lighting-based data transmission, which could revolutionize the way we connect to the internet.

LED Light Bulb

Conventional wi-fi is emitted using mirowaves or radio frequencies. The great conundrum of physics is that light travels both in particles and waves, a property which also makes it compatible with wavelength data transmission. Although li-fi has been in development for some years now, the most notable recent accomplishment belongs to Chinese professor Chi Nan, who managed to construct a DIY lighting-based data transmitter from basic retail components.

“LED Lighting Creeps Toward Tipping Point”


It’s only a matter of time before LEDs make serious headway into the retrofit market. Forbes predicts that by 2021, LEDs will make up approximately half of all retrofits in a market where they currently only make up about 5%. Read more…

Cree Announces Dim-To-Warm LED Lights

Durham, N.C.-based LED manufacturer Cree has just announced that they are adding a dim-to-warm option in their LMH2 LED module family of lamps. This is significant because although LEDs are better at dimming than fluorescents, they do not inherently change colors as they dim like an incandescent. But now incandescent lovers can enjoy the warming colors of a dimming incandescent without all the wasted energy. Read more…

“Glow-In-The-Dark Paths Could Be The Future Of Street Lighting”

A park in Cambridge, England has tried out an unconventional method to lighting the paths at night: glow-in-the-dark gravel. Known as Starpath, this resurfacing material is able to absorb ultraviolet light during the day and release it at night in a bluish glow. Read more…
