Cree and LED lighting are starting a revolution

Indiana Tech upgrades oldest building on campus with LED lighting

Tuesday, November 23rd, 2010

Built in 1857, the Administration Center at Indiana Tech University is a landmark for generations of alumni who know that even as the campus grows, they can always count on recognizing the familiar historic brick building when they visit.

And now, the oldest building on campus is historic for another reason: It’s the first building on campus to boast energy-efficient Cree LED lighting.

The 153-year-old building was gutted for renovation in October 2009 with the goal of achieving LEED (Leadership in Energy and Environmental Design) certification. The resulting work transformed the pre-Civil War era building into a haven of energy-efficient technology and sustainable design.

The historic Administration Center at Indiana Tech is a landmark for alumni.

When architect Terry Thornsbury of Viridian Architectural Design began planning the project, he said he knew he wanted to incorporate LED lighting.

“We wanted something that would help get us as many points as possible in the LEED system and reduce energy but also have a pretty good return on investment,” Thornsbury said. “Anyone who comes to me saying they want to save energy, the first thing I’m going to tell them is you’re going to want to do LED lighting because it makes sense these days to reduce energy consumption.”

Ninety-eight percent of the building is lit with Cree LED lighting.

The three-story building is lit 98 percent with Cree LED lights, helping the Fort Wayne, Indiana-based college conserve energy, reduce maintenance and provide beautiful light for employees, students and alumni. The 10,957-square foot building features:

  • 97 Cree LR24™ LED troffer lights. Offices, conference rooms and corridors illuminated with beautiful, clean white LED light. Each light consumes only 44 Watts while delivering 3,200 lumens. The high-quality light features rates 90 on the Color Rendering Index with a color temperature of 3,500K.
  • 61 Cree LR6C™ LED downlights.  Each light consumes only 10.5 Watts while delivering 650 lumens. The lights rate 92 on the Color Rendering Index and also feature a color temperature of 3,500K.
  • Long lifetime. The Cree LED lights are designed to last 50,000 hours. At the 50,000 hour mark, Cree’s LED lights are designed to provide at least 70 percent of their initial light output. That means the lights in the Administration Center could last more than 19 years based on the university’s projected use of 10 hours a day, five days a week.
  • Energy Efficiency. Over the long life of the LED lights, compared to a fluorescent downlight, the energy-efficient lighting in the Administration Center can save an estimated 259,700 kWh, which avoids 270 tons of carbon dioxide emissions.
  • Intelligent Control. The Cree LED lights work with an Intelligent Lighting Controls system with occupancy sensors and daylight harvesting, a control system that helps conserve even more energy by automatically adjusting the light level based on how much natural daylight is shining through the building’s large, preserved windows.

The University also worked with Primary Engineering, Inc., a Ft. Wayne, Indiana-based firm dedicated to sustainable design and CM Buck and Associates, Inc. which distributes Cree LED lighting in the Ft. Wayne area.

Indiana Tech Facilities Director Mike Townsley said he was skeptical an all LED-lit building would provide enough light for employees to work under. But that hasn’t been a problem, he said. Instead, employees are taking advantage of dimmers installed in each room. He said most employees are keeping the lights in their offices dimmed to 50 percent, which helps save even more energy.

“We’ve heard positive feedback about the lights,” Townsley said. “So far I’m pleasantly surprised.”

Mike Peterson is one of the university officials who moved into the newly-renovated building in July. He said he likes the controllability the dimmer in his office offers. He also enjoys the quality of the LED light.

“There’s good light distribution around the room,” Peterson said. “It doesn’t feel like there are dark areas or shadows.”

As director of Alumni Relations, Peterson says there’s another benefit to the LED lighting: Alumni like it.

“When you’re talking with alumni, any time you’re doing anything that’s technologically advanced it’s a plus,” Peterson said, adding that it’s a bonus that LED lighting technology is helping the school conserve energy. “[Alumni] feel like we’re being smart with the money that’s invested by them,” he said.

The building houses the Alumni Welcome Center, which is designed to be an inviting place complete with a fireplace made with bricks salvaged from the building. The warm, recessed Cree LED lighting adds to the ambiance, he said.

The Administration Center renovations were made possible by a $2 million donation from alumnus Wilfred Uytengsu, Sr., who wanted the money to go toward energy-efficient improvements. The building was recently renamed the Wilfred Uytengsu, Sr. Center in his honor.

And while Thornsbury was initially hoping to achieve LEED Silver level certification, the project exceeded expectations and has been submitted for Gold level certification. We’ll let you know when Indiana Tech receives final word from the U.S. Green Building Council.

September Cree LED lighting contest winner to prove naysayers wrong

Thursday, November 11th, 2010

Michigan resident Carol Thompson wanted to try LED lighting – or so she thought. But then someone told her that “the color spectrum was altered and they didn’t light too well.” Curious Carol didn’t let speculation stand in her way. She set off to Google the prospects of LED lighting.

“I found the information quite contrary to what I had been told,” Carol told me in an email.

Her quest to find out the truth about LED lighting led her to our contest. She submitted a photo of the lonely recessed light in her home office. Carol is the September winner of our LED lighting giveaway. She wins five Cree CR6™ LED downlights.

Here's the photo Carol submitted in our September contest.

Here's the photo Carol submitted in our September contest.

Here’s what Carol is going to find out when she installs her new lights. They deliver beautiful light, providing the quality you would expect from an incandescent. And her new lights won’t slurp up a lot of energy. Each CR6 LED downlight only consumes 10.5 Watts, and can replace a 65 Watt incandescent light. (Yes, the time has come to say goodbye to those Halogen lights warming up the cans in your ceiling.)

Carol’s new lights provide warm light (2700K for those of you in-the-know) and they’re dimmable to 5 percent. Bonus: She’ll use even less energy when the lights are dimmed.

And, Carol’s new Cree LED lights are designed to last 50,000 hours, which means they could last more than 17 years if she leaves them on for eight hours a day, seven days a week. It’s a good thing too, because Carol says the office lights are on a lot because her husband works at home.

When she installs her new CR6 LED downlights, she should invite over the person who told her that LEDs don’t make good lighting. We’d love to be there when she flips the switch so we can see their surprised look and hear her offer a big “neener-neener-neener” under her breath.

Congratulations, Carol! If you want to prove any LED lighting skeptics in your life wrong with Cree LED lights, enter our November contest for your chance to win five Cree CR6 LED downlights. And if you just can’t wait, look up a distributor near you.

Idaho resident wins Cree LED lighting contest, will finally turn on his living room lights

Monday, August 30th, 2010


You know the lighting in your home isn’t working for you when you intentionally avoid turning the lights on. That’s what Jerry Saltzer has been doing in his home’s living room and office for some time. Instead, he relies on floor and table lamps to illuminate the areas. How come?

“The living room (and office) in our house is equipped with incandescent downlights in 16.5 foot ceilings,” Saltzer told me in an email. “The light they produce is fine, but replacing those light bulbs is such a big production that we are inclined to leave them off as much as possible and use floor and table lamps instead.”

Jerry is the winner of the Cree’s July LED lighting giveaway. He submitted this photo of his problematic lighting situation:

July Contest Winner

Jerry wins five Cree LR6™ LED Downlights, which he plans to install in his living room. The LR6 downlight consumes only 10.5 Watts and delivers the warm light of a 65 Watt incandescent light. And Jerry’s new LED lights are designed to last 50,000 hours, which means he won’t have to deal with the hassle of swapping out his living room lights for years to come.

“Installing LED lights with an expected lifetime of 50,000 hours means that we can turn them on every evening and yet probably won’t need to change them until 2050,” Jerry wrote.

There are only a two days left to enter the August Cree LED Lighting giveaway. Just upload a picture of bad lighting in your home or office to Cree LED Lighting Revolution and you could be featured here next month.

How can grocers make their fruits and veggies pop? Hint: It involves LED lights

Thursday, August 12th, 2010

The ladders at a Michigan-based grocery chain are being used a lot less these days now that the produce sections are lit with Cree LED lights.

Up until a few months ago, employees at the three Value Center Marketplace stores used to haul out the ladder every couple of weeks to replace the burned out 90-Watt Par 38 spotlights that lit up the fruits and veggies, according to store owner Ron Fariada.

But earlier this summer, Ron replaced the energy-wasting incandescent lights in the produce sections at all three of his stores with energy-efficient Cree LRP-38™ LED lights. His new LED lights consume only 11 Watts of energy and provide beautiful, warm light that helps make the color of the store’s fruits and vegetables pop.

“It’s just worry free,” Ron said. “I’m not going to have to worry about changing any bulbs for years. There was an upfront cost, but you’ve got immediate savings as far as power.”

When Ron opened the first Value Center Marketplace in 1989, he was committed to offering the freshest quality foods and the best in family value. More than 20 years later, Ron now runs three of the grocers just outside Detroit, Michigan.

In all, he replaced 50 incandescent lights at each of stores with Cree LRP-38 lights, for a total of 150 LED lights.

_MG_0693

Ron said he expects a two-year payback on his LED lights when he takes into account the energy savings and maintenance savings. The produce lights in his stores are on for about 12 hours a day, seven days a week. And since the LRP-38 LED lights are designed to last 50,000 hours, Ron could continue to save energy and money for another nine years before he needs to consider replacing the lights.

_MG_0627

Already he’s noticed that when he walks under his new LED lights, the area feels cooler than when the 90 Watt incandescent spotlights were lighting up the area.  Ron said he also expects to see HVAC savings.

The produce at Ron’s stores is hand-picked daily from the local farmers market. And now, it can truly shine under LED lights.

May LED lighting contest winner is racking up the energy savings with home renovations

Wednesday, June 23rd, 2010

Minnesota resident Nicole Ronich is always on the lookout for LED lighting. Her father introduced her to LEDs years ago and lately she’s noticed that LED lighting is on the rise. She even recently learned that the Minnesota Twins’ Target Field features display boards lit with LEDs.

So when Ronich saw that Cree was giving away LED lights in a monthly photo contest, her thoughts drifted to her dimly-lit bathroom. She snapped this photo and later won the May LED Lighting giveaway.

May Photo Contest Winner

Nicole Ronich won the May LED lighting giveaway with this photo.

Here’s what she wrote about her bathroom lighting: “This is an old and hideous light fixture that is so inefficient. It also blows out light bulbs every other week. It gives my bathroom the shadow effect. I hate putting my make up on under it!”

I don’t blame her for not wanting to apply her makeup under this light. Hopefully her new energy-efficient LED lighting will improve lighting conditions in her home. Here’s what she wrote me when I e-mailed her to say she won the May photo contest:

“We have an older home and have been doing a ton of remodeling and updating of appliances to energy efficiency, improving insulation and replacing drafty doors, etc. It has been fun watching the utility bills drop! So, changing to a more efficient light bulb would be another step in the greener direction. My bathroom is going to be one of our last projects and to have better lighting would be awesome.”

If you’re jealous of Nicole’s new LED lighting, then enter our June LED Lighting giveaway for a chance to win some energy-efficient lights of your very own. Here’s how easy it is to enter:

Then, maybe I’ll be writing about your new lights soon! Congrats, Nicole!

Vintage light bulbs may be trendy for restaurants, but LED lights are a better option

Tuesday, June 8th, 2010

A restaurant with bad lighting is a bummer. Bad lighting can kill the mood and even make food look discolored. Customers can leave unimpressed. Owners could be stuck with expensive electric bills and a restaurant that has a bad lighting reputation.

So I wasn’t surprised to read this article in the New York Times, which declares that “a lot of thought and expense go into restaurant lighting,” particularly at upscale restaurants.

But what I was surprised to read is that some restaurant owners in New York City are harkening back to  Thomas Edison’s heyday and installing antique-looking, energy-wasting reproductions of Edison’s first light bulb.

There is no excuse for this. And believe me, I’m all about beautiful design and I even support being trendy from time-to-time.

Sure, these retro-looking filament-filled lights have a charming appearance, but they consume more energy than standard incandescent light bulbs. And since restaurants leave their lights running for many hours a day, those vintage-looking bulbs are sucking a lot of energy and driving up utility bills. Not to mention putting out enough collective heat to have a real impact on air conditioning needs!

Restaurant owners who are serving up these Edison reproductions say the lights are a bit nostalgic and the warm light is flattering.  To that I say: Perhaps you need a more creative lighting designer. Have they seen some of the unique lighting designs that incorporate LEDs?

On a regular basis, the green design blog Inhabitat posts some of the most incredible energy-efficient LED lighting designs your imagination could conjure up. Among them are:

I mean seriously, if designers can create LED lights out of soap, imagine what they could do for an upscale restaurant in New York City?

These beautiful glass pendant lights are lit with energy-efficient Cree LEDs.

Sure, creating a custom LED light fixture for a restaurant might not be as cheap as buying an incandescent bulb. But the energy and maintenance savings from LED lights can quickly add up. And perhaps these restaurants will attract even more diners who are wooed by both beautiful lighting AND energy-efficiency. With LED lights, you can have both.

April LED Lighting contest winner will light up his Hawaiian-themed coffee shop

Thursday, May 27th, 2010

Charlie Trinh was surfing the Internet looking for “green products” when he found CreeLEDRevolution.com. The Houston, Texas resident says he saw our monthly photo contest and decided to give it a try.

“I needed brighter lights for my business,” Charlie said in an e-mail to me. He owns a coffee shop with a Hawaiian theme. “I want to convert over to LED lights but I would like to sample it out first before buying.”

Well, lucky for Charlie, he was the winner for our April LED lighting giveaway. He submitted this very dark photo of the counter at his coffee shop. This dark photo won Charlie five Cree LRP-38™ LED lights. His new 11 Watt LED lights are designed to last 50,000 hours, which means he could leave them on for eight hours a day, 365 days a year and they could last 17 years! And did I mention that would be an 85% percent energy savings if he replaced electricity-sucking incandescent?

April contest LED lighting winner

“That was my coffee shop with all the lights on, and it was still dark,” Charlie wrote.

We’re excited to bring LED lights into Charlie’s life and business. Prior to winning these lights he said his only experience with LED lights was with his LED flashlight. (You may recall that was also the case for Fargo, ND homeowner Dave Hultin).

Are you jealous of Charlie’s new energy-efficient Cree LED lights? Don’t be. Just enter our monthly photo contest for your chance to win five of your own. All you have to do is take a photo of bad lighting in your home, office, business, etc. and submit it here.

Seriously, I bet you can do that in five minutes. And spending five minutes to snap and upload a picture seems like a good use of time if it means you have a chance to win five Cree LED lights. Ready, Set, Go!

Happy 25th Birthday, CFL. Your days are numbered.

Wednesday, April 14th, 2010

Did you know the CFL is celebrating its 25th birthday this year? We just found out from the folks at Sylvania, who plan to commemorate the occasion tomorrow at Light + Building, the big lighting tradeshow happening this week in Frankfurt, Germany.

To its credit, the CFL has come a long way since it was born in 1985. Its average life span doubled, its size shrunk considerably, it got cheaper and there’s less mercury inside. But it still has mercury inside, which means if it ever breaks, you can’t just sweep up the glass and be on your way. You’re supposed to follow these steps, which include airing out the room, washing or even throwing out materials that come in contact with the broken bulb and more.

CFL BIRTHDAY

But we’re realists. We realize the CFL – for all its toxic faults – still consumes less energy than the 130+ year old incandescent bulb. So we’re not going to crash the CFL’s birthday party because, frankly, this may be the last year folks show up to celebrate.

The CFLs days are numbered. The LED Lighting Revolution is gaining traction because most LED lights consume even less energy than CFLs and they do so without containing toxic mercury. LED lights are designed to last significantly longer than CFLs. And LED lights reach full brightness immediately.

And I know what you’re thinking. You’re thinking: “It’s not really fair of you to rain on the CFL parade when I can’t even buy a 60 Watt equivalent LED bulb at the store.” To that I say touché, and then I’ll duly note that there are plenty of other LED lighting products made by Cree and other companies that can successfully replace incandescent and fluorescent lights. And innovations are happening all the time.

So happy birthday, CFL. Sorry we can’t make it to your party, but we’re busy Lighting the LED Revolution.

New Cree LED module may help bring more LED lights to market

Tuesday, April 6th, 2010

It’s not easy to make an LED light. Designers have to consider a lot of factors in their fixture designs including chip selection, LED packaging, color mixing, optics, electronics, thermals, oh my. 

But we’re making it easier for manufacturers to overcome the common design issues they’ve faced when trying to incorporate LED solutions into their lighting fixtures.

Today we announced the launch of Cree LED Module LMR4. This module can make it easier for designers to create LED lights of their own, which means ultimately it can lead to even more energy-efficient LED lights on the market.

LMR4

More LED lights means it will be easier to help people break their fluorescent shackles and incandescent cuffs. It means there will be even more opportunities to bring energy-efficient, beautiful LED light into homes, offices, businesses and other places that need to be enlightened.

How can this LED lighting module help? Well, since the module contains the LED light, heat sink and driver electronics, designers can just drop this unit into their designs. This helps take some of the burden off of lighting fixture manufacturers that are interested in developing LED lights but just don’t have the experience. This can help speed up the time it takes manufacturers to develop and produce LED lights of their own, which means we can all buy them sooner. Fixture design becomes faster and easier.

And, the big bonus, is that this module produces beautiful, warm white light using Cree TrueWhite™ technology. That means designers who use this module will get access to the same light used in Cree’s fixtures. They won’t have to reinvent the wheel (or the light, as it may be). 

Watch this brief 1-minute video to see some more details about the new Cree module. Please note my awesome hand modeling skills:

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!
