A brighter idea for college dorms

December 4th, 2013

Lighting innovations have taken the world by storm over the past few years, moving us from the incandescent bulb of Edison’s day, to LED lights that use 10 percent of the energy. This efficiency gain is helping colleges brighten up for less, and also creating safer, more pleasant dorm rooms, hallways and byways. Read about how North Carolina State University is lighting the way forward.

LED Christmas lights can save energy and aggravation

November 20th, 2012

Those old-style incandescent lights? They’re still around, certainly. But more and more, they’re being crowded out by the new kids on the illumination block: The longer-lasting, more energy-efficient Light Emitting Diode (LED) option.
LEDs have been around for a few years now, and they’ve got quite a bit going for them. Promotional materials tout energy savings of 80 percent or more over their incandescent brethren.

Shining a light on the light bulb controversy

May 19th, 2011

By Barbara Kessler
Green Right Now

You’d think that new light bulb efficiency standards would be a pretty basic matter. Light bulbs, after all, didn’t change much for more than 100 years. At home, we used the classic household incandescent. At work, we toiled under rows of tubular fluorescent lights.

Astronauts blasted off to the moon. The Internet revolutionized communication. Light bulbs stayed the same.

Push back progress on light bulbs? Not a bright idea

March 11th, 2011

Rep. Joe Barton’s last bright idea – to apologize to BP for having to make reparations for the oil spill in the Gulf of Mexico – earned him national ridicule.

His pandering may not have misfired (much) in the conservative-leaning Texas district he represents, but it was a rude affront to those who earn a living on the gulf, and anyone who cares about the workers and wildlife there.

Now, less than a year later, Barton again appears to have his finger on the pulse of the mean-spirited minority.

Cree one ups Edison — makes an LED for home use

January 27th, 2011

Move over CFLs. LEDs are ready to take on the residential market.

Cree, Inc., the North Carolina-based LED light manufacturer, is crowing today about its new LED-based light bulb that the company reports is the brightest and most efficient LED replacement for the standard 60-watt bulb.

The Cree TrueWhite® as its being called will bring the end of the “horse-and-buggy era” incandescent bulb invented by Thomas Edison 131 years ago, according to a Cree announcement.

The TrueWhite bulb, which emits 800 lumens and yet consumes fewer than 10 watts, has been sent for third party testing to verify its output and energy efficiency.

LEDs offer an energy-efficient alternative for holiday lighting needs

November 24th, 2010

If you must get carried away with your holiday displays, LED lights use less energy and last longer.

Christmas, of course, isn’t a famously “green” time of year, unless you are talking about the trees we cut down or the currency that seems to fly endlessly out of our wallets and purses. The spirit of the season almost insists that we throw caution (and energy) to the wind when it comes to fancying-up trees and winning the arms race on outdoor decorations.

Give greener electronics this holiday season

November 11th, 2010


If visions of a new computer, an upgraded cell phone or a flat screen TV are dancing in your head this holiday season, you don’t necessarily have to feel guilty about it. No one will confuse adding 50 inches of viewing pleasure with planting a tree when it comes to carbon footprint, but bringing that shiny new toy into your home may not be quite the environmental faux pas it used to be.

From design to operation to disposal, electronics are getting a little more eco-friendly. That’s a good thing, too, since we seem to be incorporating more and more of them into our daily lives. According to the Consumer Electronics Association, a typical American household features 24 electronic devices, from clock radios to DVDs and Blu-Ray players to computers and TVs.

Introduction to LEDs: What you need to know

October 4th, 2010

This LED uses just 6 watts.

As with other technologies, advances in lighting just keep coming. Now that you’re somewhat comfortable with CFL — compact fluorescent lamp — bulbs, get ready for things to change again. The latest generation of LEDs — light-emitting diodes — are here and manufacturers claim they rival the look, dimming ability, and light quality of incandescents. Better yet, LEDs contain no mercury, and last up to five times longer than CFLs and 50 times longer than incandescents. They are pricey, many sell for $60 or more, but could save about $300 in electrical cost over its life compared with an incandescent.

Consumer Reports’ top picks in CFL lightbulbs and a sneak peak at LEDs

September 9th, 2010

According to the recent survey by Consumer Reports, eight in 10 (81 percent) Americans have purchased energy-efficient lightbulbs. The latest tests for compact fluorescent light bulbs (CFLs) showed there’s no shortage of inexpensive, money-saving, energy-efficient options. Most delivered on brightness and many provided color that was closer to incandescents’ than in earlier versions. All bulbs tested had significantly less than 5 milligrams of mercury, the cap set by Energy Star for those bulbs.
