Cree and LED lighting are starting a revolution

Hear Cree CEO Chuck Swoboda speak on energy panel at Duke University

Monday, November 1st, 2010

What steps should we be taking to plan for the energy demands of tomorrow? It’s a question that Cree CEO Chuck Swoboda will join other panelists in addressing during the “Energy for Tomorrow: Accelerating Energy Innovation” event at Duke University on Thursday.

The event at Duke’s Fuqua School of Business will be moderated by TIME and Fortune editor Michael Elliott, and features our CEO as well as President of Shell WindEnergy Richard Williams and President of the Alliance to Save Energy Kateri Callahan.

And don’t worry about making the trek to Duke University, you’ll be able to watch it if you have an Internet connection. There will be a webcast of the panel at 4 to 6 p.m. EST Thursday and you can tune in here simply by clicking on the “LIVE: Panel Debate” link under “Online Resources.” You’ll be redirected to Duke’s Ustream channel. You will need Adobe Flash to tune in from your computer.

The event is being presented by TIME and Fortune in partnership with Shell and Fuqua’s Center for Energy, Development, and the Global Environment. Organizers say the “Energy for Tomorrow” program was inspired “in the wake of unprecedented growth in global demand and ever-pressing environmental issues” which has put the energy sector at a crossroads.

Until now, the “Energy for Tomorrow” program has focused on letting top business school students from around the world submit their ideas on a sustainable energy future. But this panel will allow business leaders to share their thoughts.

Educational forum on American Power Act scheduled June 15 at Cree

Wednesday, June 2nd, 2010

You know what’s not easy? Reading, digesting and understanding a 987 page bill. That’s the length of the American Power Act, a U.S. Senate bill that (among many things) aims to reduce U.S. greenhouse gas emissions by 17 percent by 2020, and by 80 percent by 2050.

Thankfully, the folks with the Environmental Defense Fund want to help people understand that 987 page bill. So the Raleigh, NC office of the EDF is sponsoring an educational forum to teach the public about the recently proposed American Power Act. The forum will be from 9:30 a.m. to noon on Tuesday, June 15 at the Cree Auditorium.

The forum will focus on what the American Power Act could mean for growing both the North Carolina and U.S. economies, according to Robin Langdon, an energy efficiency specialist with EDF.

Here’s the lineup for the forum:

Presenters

Introductions and Overview of the American Power Act
Robin Langdon, Environmental Defense Fund

Climate Solutions: A  Supply Chain Perspective
Marcy Lowe, Duke University’s Center for Globalization, Governance and Competitiveness

Clean Technology Market Opportunities
Greg Merritt, Cree

Clean Technology Investment Opportunities
Cody Nystrom, SJF Ventures

Potential for Job Growth and Local Communities

So if you’re interested in learning more about what the American Power act could mean for jobs, communities, manufacturing, clean technology markets and investments, RSVP to EDF here.

North Dakota homeowner is happy his Cree LED lights don’t have “Star Wars light saber effect”

Thursday, April 29th, 2010

Dave Hultin recently wrote me through the contact form on the LED Revolution site saying he joined the revolution more than a year ago, when he outfitted his home with LED lights. I interviewed him last week to find out more. This is his story:

When Dave Hultin began designing his home in Fargo, North Dakota, he knew he wanted to incorporate energy efficient lighting. That’s when he started doing his homework. He knew CFLs were out of the question because he said his wife wasn’t keen on the potential health issues that could arise if any of the mercury-laden CFLs ever broke.

One night Dave was holding his son’s LED flashlight and he said he started to wonder if LEDs were being developed for residential lighting. He found a 40 Watt equivalent LED bulb online and ordered it.  He was disappointed when it arrived and it had a “laser beam feeling.”

“I wasn’t ready to give up,” he said. “I thought: ‘there’s got to be something better.’”

Dave said he started to read about the Cree LR6™ LED recessed light that, at the time, was only 12 Watts but delivered warm light. (A newer version is now only 10.5 Watts!). So he found a local supplier and bought four and had an electrician install them in his master bedroom, which was still under construction. He didn’t even have switches in place yet.

Dave was a skeptic and wanted to see if they would have the “Star Wars light saber effect” or if his family could actually live comfortably under the LED light. After the electrician installed his test lights, Dave visited the construction site to see how they looked.

“I remember that first night when I came there. I went there when it was dark. I was expecting the best, but hoping I wasn’t going to get a wimpy, little glow,” Dave said. “So I tentatively turned it on and I went ‘Yes!’ That’s when I was convinced it was a good thing.”

So Dave placed an order for more LR6 LED lights. In all, he placed 44 in his living room, kitchen, dining room, hallways, piano room and master bedroom. (Here are some pics Dave took and e-mailed me):

“The biggest thing that I would say about the light quality is that I don’t have to talk about the light quality,” Dave told me. “It’s there and it’s what I would expect. I don’t have the Star Wars light saber effect going up to the ceiling. People don’t notice that something is different, they just see that it’s there and it works.”

Dave said he spent $3,867 on the LED lights. And by his calculations, the lights will pay for themselves in energy savings after three years (he has already lived in his home for a year). But since the LR6 LED lights are designed to last 50,000 hours, he’ll be racking up the savings long afterward.

“When I go to a relative or a friend’s house and notice they have a burned out bulb, I look at my watch and think: ‘In another 12 to 15 years, I’ll be doing that too,’” Dave said.

Chocolate bunny melts under incandescent light, survives LED light

Wednesday, March 31st, 2010

I was one of the most popular people at work this week after word spread that I was melting chocolate bunnies with light bulbs. People kept stopping by my desk to ask if the scuttlebutt was true. And when they found out it was true, several co-workers declared that I have the best job ever.

But I wasn’t melting the bunnies for fun, or even for a snack. This experiment was for the sake of the LED lighting revolution.

I can preach the benefits of energy-efficient LED lighting until my voice goes hoarse (which I’ve done) or type out blog posts, tweets and e-mails until my fingers callous. But, let’s face it, seeing is believing.

So I turned an empty office into a studio for my experiment. I placed chocolate Easter bunnies under a 12 Watt Cree LRP-38 and a 65 Watt incandescent floodlight. Both lights are designed to be hung from tracks. And, despite their Wattage differences, they’re a relatively fair comparison — a 12 Watt LRP-38 can replace Halogen bulbs up to 90 Watts (the folks at Furniture Row in Denver, Colorado replaced one thousand 90 W Halogens with LRP-38s).

Here's the setup.

Here's the setup.

The results were exactly what I expected. The bunny under the incandescent light melted into a pool of chocolate that spilled over the plate and onto the desk. The LED bunny kept his shape, with just the tip of his head becoming soft when I touched it with my fingertip. Watch the time lapse video to see the incandescent bunny’s downfall:

 

Once the incandescent bunny collapses, you can see my hand reach over and reposition the plate. That’s because that sucker fell backwards and out of the video shot, so I had to reposition him so we could all watch him melt.

I hope the video conveys how much more energy-efficient LED lights are. Since LED lights consume significantly less energy than incandescent bulbs (and even compact fluorescents), they don’t emit as much heat. In fact, LEDs are sensitive to heat, that’s why good thermal design is important for a long-lasting LED light, and that’s what the heat sink helps accomplish (the metal fins or slots that surround LED lights).

Hmmm. Perhaps I’ll have to start melting chocolate with light bulbs around every holiday. If you’ve got suggestions of what I should melt next, post them in the comments!

California city once known as a getaway for Hollywood stars turns focus to sustainability

Tuesday, March 9th, 2010

Most people who visit Indian Wells, California, are probably drawn in by the four world class resorts, the spas and the lush golf courses. The resort community in the southern California desert became a retreat for celebrities after Lucille Ball and Desi Arnaz opened the Indian Wells Hotel in 1958. Since then, city officials have worked to make Indian Wells a premiere destination in the Coachella Valley.

These days, city officials are keen on sustainability, and energy-use reduction has become a key goal for the city. I had the “tough” job of visiting Indian Wells last month for an LED City® Council meeting, and while I was there I had the city’s management analyst Susan Weisbart give me a tour of some of the city’s LED lighting installations.

Indian Wells was the first California city to become an LED City. The LED City program helps municipalities speed up the adoption of energy-saving LED lights by connecting them with information they need to make informed decisions about installing LED lights.

One of the first LED lighting installations in Indian Wells involved swapping out incandescent lights that lit the outside of city hall and other municipal buildings with 12 Watt Cree LR6™ recessed lights. It’s a change that city officials say saves nearly $7,000 a year in energy costs. That’s not counting the maintenance savings of not having to replace burned out bulbs, since the LED lights they installed are designed to last 50,000 hours – or 17 years if they’re on 8 hours a day!

The city also has plans to replace the 50 Watt halogen lights illuminating the signature palm trees lining city streets with 11 Watt LED lights. Get this: The city estimates it can save $10,095 in energy costs per year once the project is complete!

Watch my LED tour and interview with Susan to see what Indian Wells is doing to save energy and money:

Raleigh, NC celebrates three year commitment to LED lighting

Tuesday, February 2nd, 2010

Think back to February 2007. What were you doing back then to save energy? It’s hard to believe that just three years ago, the push for energy-efficient lighting focused on CFLs. It was in early 2007 that Yahoo launched a website urging people to switch to CFL bulbs.

But while much of the world was focusing its attention on CFLs, the city of Raleigh was setting its sights on even more energy-efficient technology: LED lighting.

Yesterday we celebrated Raleigh’s three year LED City® anniversary. In February 2007, Raleigh became the first city in the world to join the Cree LED City program, an initiative to deploy and promote LED lighting in cities throughout the world.

Raleigh joined the program by installing LED lights at just one spot in the city to see what results the city would achieve. Three years later, city officials are so impressed with LED lighting that Raleigh now has more than 40 installations, ranging from accent and indoor lighting to street and parking lot lighting.

So how much is the city saving by using LED lights? City officials estimate the city is saving $215,000 a year on energy and maintenance costs.

In fact, city spokeswoman Jayne Kirkpatrick is so jazzed about the savings that she tried to quantify it for taxpayers. She told us that the city’s annual savings from LED lighting is the equivalent of four police officer or firefighter salaries; five years of sidewalk repairs; five years of sports field renovations or the cost of nearly two brand-new garbage trucks.

Want to see some of the places that boast LED lighting in Raleigh? Take a look at this Google map I put together. The map includes video of the following locations: Underground parking deck at Raleigh Convention Center, street lights outside Progress Energy Headquarters, pedestrian lighting at Exchange Plaza, street lights at Raleigh Convention Center, architectural lighting on City Plaza Art Towers and solar street lights at Campbell University Law School parking lot.
