Which would you rather have in your back yard- HID, CFL or LED?

Tuesday, November 29th, 2011

Most people are familiar with the acronym NIMBY, or the phrase Not In My Back Yard. Usually it refers to something people feel they desperately need, but don’t want to live near.

NIMBY

It could be a major shopping center. Yes, it would be great to have your favorite retailers close to home rather than having to drive 15 miles to get to them. But you don’t want it within walking distance, because then you’d have to deal with the noise, the traffic and everything else that goes with it.

The same goes for landfills and power plants. You’re glad your favorite appliances have power and that your garbage has somewhere to go, but you don’t want the facility that generates the power or your garbage’s new home to be visible from your back door. Yet at some point, if we don’t change our ways, that’s exactly what could happen.

One way you can protect your personal back yard is by specifying LED lighting instead of High Intensity Discharge (HID) fixtures in any lighting projects. And the beauty is, making that move not only reduces waste and potential environmental hazards – it helps you save money. Here’s how.

Typical well maintained parking structures that operate 24 hours per day, 7 days a week with metal halide technology will be scheduled for group re-lamping approximately every 9 months. Which means a parking structure with 1,000 lamps will potentially add 1,000 lamps (bonus: which contain mercury!) to the waste stream every 9 months. Those lamps take up real estate, and as Will Rogers said, they’re not making any more of that.

So sooner or later, the disposal company has to build a new landfill – maybe next to you. If that’s not bad enough, as much as we’d like to believe that all lamps containing mercury ranging from the 1,000 HID lamps in our example above to the CFL lamps the neighbor down the street is using in their home will end up being properly recycled, sadly we know that this won’t always be the case. So as disturbing a sight that new landfill might be, what could be even more disturbing is the potential mercury that is being released from the improperly disposed lamps you can’t see.

Grandma Learns How to Clean Up a Compact Fluorescent Light Bulb

Contrast this with an LED solution. LEDs contain no mercury. In addition, LED solutions can be designed to provide near maintenance-free service for more than a decade, even in our 24/7 parking structure example. Over a ten year period the owners of that 1,000 HID lamp parking structure will need to determine how to safely dispose of more than 12,000 lamps that a properly designed LED solution could avoid altogether. But there’s more to it than that. The materials used in BetaLED® luminaires are also RoHS (Restriction of Hazardous Substances) compliant, which means dangerous substances commonly used in electrical and electronics appliances are also avoided. In addition, BetaLED products are highly recyclable making it much less likely that they’ll see the landfill. Instead, they end up in other products – perhaps even in new LED luminaires. Ah, the circle of life.

Finally, we know LEDs can save significant energy consumption. But when coupled with adaptive control systems that can range from a simple occupancy sensor to a complex network based system, LED luminaires can save even more energy consumption. Let’s look at our parking garage again. There are probably large blocks of times when certain areas are vacant. Keeping the lights operating at a level that always assumes occupancy is just wasting energy and money. But with LED products that utilize adaptive controls you can significantly reduce energy consumption even further during periods of inactivity and instantly increase light levels as spaces become occupied. Not only does that reduce energy cost – it also can extend the longevity of an LED system as well.

The best way to make NIMBY work is to avoid the need in the first place. How could you use LED luminaires to keep your back yard landfill- and power plant-free?

Making solar panels more efficient with Silicon Carbide Schottky Diodes

Tuesday, October 18th, 2011


We’ve all been told to be more aware of our exposure to the sun…that the sun’s rays are damaging. So it’s weird, sort of, when you consider that for centuries, countless civilizations have looked to the sun as a symbol of power and strength.

We get a little excited about a renewed fascination with the sun because we see opportunity. Opportunity to harness the sun’s strength to power our electronics. And because solar panels themselves are pretty complex feats of engineering, that’s where we come in.

As solar panels become more and more commonplace, the design considerations for converting light into electricity must focus on increasing energy efficiency. At Cree, we like to think that we’ve become the “ray of solar power efficiency” through our development of the silicon carbide (SiC) Schottky diodes that increase the conversion efficiency of solar energy.

Yes, we’re getting super technical, but this is actually pretty “hot” stuff.

Cree Energy Awareness Month

First, let’s go through the basics: Solar panels are designed to absorb the sun’s energy and convert it to a positive DC voltage, which varies with the intensity of the sun’s rays to which the panels are exposed. That voltage is raised (or “boosted”) to a fixed DC voltage by means of a boost converter circuit either at the solar panel itself, or in the first phase of the power inverter, which takes the fixed DC voltage from the panel and converts it to a usable AC voltage at a fixed frequency. Conventional silicon Schottky diodes, when used for both the boost phase and in the inverter circuitry, typically contribute to an overall inverter efficiency of around 96 percent, due to a phenomenon known as switching loss (i.e., the circuit “wastes” about 4 percent of the energy produced by the solar panel in converting it to AC power).

Now that you’ve got that down…let us reiterate, conventional silicon diodes are 96 percent efficient. That’s pretty good, but…

If you use Cree’s SiC Schottky diodes, the inverter circuit operates at significantly higher frequencies, and virtually eliminates these diode switching losses, which has the effect of dramatically improving the overall inverter’s energy efficiency. This more efficient design enables more of the energy from the solar panels to get converted to usable electricity. With Cree SiC devices, the inverter’s average efficiency can be boosted by 2 percent, representing a 25 percent reduction in inverter losses. And when you’re making usable energy—every percent increase in efficiency counts.

So now you know enough be a little dangerous about solar panels and Schottky diodes. But don’t forget your sunscreen because while more sunlight makes a happy solar panel, it can also make for miserable sunburn.

Cree LED Contest Series: From Spooky to Smiley, Cree LED Lights transform two rooms

Tuesday, July 19th, 2011


This is the second part of a five part series that follows up with winners of Cree’s monthly LED lighting giveaway. Each month, Cree gives away at least 5 Cree LED lights in a photo contest. To enter, submit your bad lighting photo here.

MONDAY: We revisit July 201 winner who has developed a love for Cree LED lights.

TUESDAY: We see how the October 2010 winner made over his office and how a bathroom went from spooky to smiley.

WEDNESDAY: We revisit an energy professional who is using his LED lighting from the December 2010 contest to spread the good word.

THURSDAY: It’s not all about your home. We revisit the February 2010 who shows us what LED lighting can do in a retail space.

FRIDAY: We’ll show you how LED lighting can even help a plein air painter. Confused? Stay tuned to see what our March 2010 winner did.

October 2010 Winner Mark Rogers

One of our big fears is that people will try subpar LED lighting, and that their bad experience will prompt them to forever shun LED technology. That’s why our judges don’t shy away from selecting a winner who already has LED lighting. Back in October 2010, Mark Rogers submitted a photo of his office, where he had installed PAR30 LED spotlights.

We’re not sure whether they were quality LED lights or not, but we are sure that they’re not really working in this application. He won five Cree CR6 LED downlights, which are the right fit for the recessed lighting in his office. It made a big difference. Take a look at his before and after photos: When I wrote Mark last year to tell him he won, he said he was excited because “there are evenings when I would love to work just under the downlights” but they weren’t providing enough light. Well, that’s not a problem anymore.

Here’s what Mark said when I recently followed up with him: “The Cree CR6 installed in minutes, without any special tools, looks like they were built-in, and the dimming is smooth and reliable. You can see the light distribution is amazing – a perfectly natural look with plenty of beam angle! Great color temperature and an elegant appearance. I am a fan!”

The color temperature he’s referring to is the warm light delivered by the CR6 downlights, which has an incandescent feel at 2700K without wasting the energy. The CR6 LED downlight consumes only 10.5 watts and is designed to last 50,000 hours, which means he could leave his office lights on eight hours a day, seven days a week, and he could go 17 years without having to replace them. But we hope he doesn’t have his office lights on for that long every day. Mark deserves some downtime!

October 2010 Runner-Up Dan Leighton

Occasionally our judges have had a tough time picking just one monthly winner. Luckily that was the case for North Carolina resident Dan Leighton who won two Cree CR6 LED downlights to replace the CFLs in his master bathroom. “My wife and I noticed an immediate change when we first flipped the switch. The Cree LEDs lit up the small area and made it feel bigger, a dramatic difference from the yellowish-orange glow of the CFLs emitted,” Dan wrote me in a recent follow-up email. “I have not done it yet, but I plan to install a dimmer now that I have that option.”

Before Dan installed Cree LED lighting in his bathroom.

We love that Dan’s new LED lighting provides the same warm light you would expect with 65-watt incandescent bulbs, but conserves significantly less energy. And he would have been hard-pressed to dim the CFLs, if he’d tried. The CR6 LED downlight consumes only 10.5 watts, and is designed to last 50,000 hours, many lifetimes longer than incandescent and even CFLs.  And it’s a good thing too, because it doesn’t look like it’s easy to change a bulb in Dan’s bathroom.

If you have spooky lighting of your own that you want to eradicate with LED lighting, enter our July photo contest. Submit a photo of scary lighting at your home or office for your chance to win five Cree CR6 LED lights.

What happens if you let a baby hold a lit Cree LED light bulb?

Wednesday, February 9th, 2011


Ever try to unscrew a light bulb from a lamp right after you shut it off? It’s one of the easiest ways to burn your fingertips.

There’s a good reason why incandescent lights are used to keep your fries warm at restaurants and to bake brownies in an Easy Bake oven: Those suckers are hot!

Stick with me on this, and I’ll explain how/why my boss’ beautiful baby boy (say that five times fast) is able to safely hold our demonstration LED bulb, the TrueWhite Light, in his tender hands.

Baby Ben safely holds our TrueWhite Light.

Baby Ben safely holds our TrueWhite Light.

Most of the energy emitted from incandescent bulbs (about 90 percent) is emitted as heat instead of light. It takes a lot of current to heat that filament enough to make it glow and produce light. That’s what makes the incandescent bulb so inefficient and explains why you’ll burn your fingers if you try to touch one once it’s turned on, or even shortly after it’s turned off.

LED lighting is about 85 percent more efficient than incandescent bulbs. Since LEDs consume significantly less energy, they don’t emit as much heat. That’s why you typically won’t burn yourself if you try to touch an LED light once it’s turned on.

Some LED boosters wrongly say LEDs don’t emit any heat. In fact, they do generate heat and it’s really important to dissipate that heat, or it can contribute to premature failure. That’s why you’ll notice metal fins wrapped around the base of most LED lights. Those fins make up the heat sink, which helps transfer the heat away from the LEDs and cool the lighting system.

The overall efficiency of LED lighting combined with proper thermal management makes it possible for our model baby to touch the TrueWhite light without burning his little hands. It also explains why this chocolate bunny barely melted under one of our other LED lights.

Those of us in the LED lighting biz have a game we love to play with our friends. We invite them to touch an illuminated LED light, such as our CR6 downlight. Then we watch as their hand reaches for the light with trepidation. Once they touch it and feel that it’s not blistering hot like an incandescent light, their face relaxes and we all have a good laugh. Yes, we really do this.

So as we prepared to showcase our TrueWhite Light, we wanted to make the efficiency of our LED bulb clear. We think baby Ben safely holding the next-generation of lighting in his precious hands does just that. And don’t worry, his mom is an LED lighting pro and she had him propped up in her lap the entire time.

And here’s a final thought for Baby Ben as he drifts off to his next nap:  If his mom screwed this LED bulb into a lamp in his bedroom, she probably wouldn’t have to touch it again until he was off to college.

Longer-lasting Cree LED lighting helps reduce lighting maintenance at Lee University

Tuesday, January 18th, 2011

How many people does it take to change a light bulb? Well, if we’re talking about the light bulbs in the lobby of the Humanities Building at Lee University, it takes three.

Three members from the university’s maintenance team must be on hand to help replace burned out bulbs in the 30-foot ceiling. To get to the lights they must first cover the ceramic tile floor with plywood so the floor won’t be damaged when they steer a scissor lift into the building.

Lee Univ Humanities Center (3)

The ceramic tiles in the lobby of the Humanities building must be covered with plywood before a lift can be steered in to reach the light fixutres.

It’s a labor-intensive, time consuming task, taking about four hours from start to finish. And they must change the lights after-hours when the lobby is empty.  So instead of doing it every time one of the fluorescent bulbs burns out, they wait and replace them all every two years, whether they’re burned out or not.

But it should be a long time before maintenance has to break out the scissor lift again. That’s because the school recently replaced the fluorescent lighting in the lobby with longer-lasting Cree LED lighting.

“We were trying to find locations that were either high risk, difficult to get to or inconvenient, and that’s how we came up with this lobby — It’s hard to get to,” university electrician Ron Broach said of the lobby placement of the school’s new LED lights.

In all, 18 fluorescent can lights were replaced with 17 Cree LR24 LED lights in the lobby of the Humanities Building at Lee University, a private college in Cleveland, Tenn. The university worked with Lytestyles, a distributor of Cree LED lighting in Tennessee, to purchase the fixtures.

Cree LR24 LED lights replaced fluorescent lighting in the lobby of the Humanities Building.

Cree LR24 LED lights replaced fluorescent lighting in the lobby of the Humanities Building.

 The new Cree lights are designed to last 50,000 hours. That means Lee University could leave them on for 12 hours per day, 7 days a week and not have to worry about changing them for at least 11 years.

Ron said based on current usage, he’s hopeful a three-person crew won’t be have to be dispatched to replace lights in the lobby for at least seven to 10 years.

Initially, the university planned to replace all 18 fluorescent lights with Cree LED lights. But there was one fixture over the staircase that was particularly tricky to reach, Ron said. Once the other Cree LED lights were installed, Ron said the light quality was so improved that it wasn’t necessary to replace the precariously placed 18th fixture.

The stairwell in the Humanities Building lobby posed challenges when flurorescent lights needed replacing.

The LED lights also makes a piece of art in the lobby stand out, he said. The Humanities Building lobby features a floor-to-ceiling mural displaying the university’s history through enlarged newspaper clippings and photos from school events. Ron says the mural looks better than ever thanks to the improved light quality provided by the LR24 LED lights.

“It has exceeded our expectations,” Ron said of the Cree LED lighting. “It was a new thing for us when we put these in, and we’ve been happy with the results. The lighting is even, it’s constant, it doesn’t flicker and the lights don’t go out.”

Now that’s revolutionary!

Denny’s restaurants begin lighting up with Cree LED lights

Friday, January 14th, 2011

I feel like I can always count on Denny’s. If I’m hungry for breakfast after sleeping in on the weekend, Denny’s serves it all the time. If I’m craving a late-night meal after a night out on the town, Denny’s is still open. It’s such a recognizable restaurant chain, and that’s one of the reasons we’re fired up that the chain has adopted our LED lighting as its preferred lighting standard for all its new and remodeled stores across the United States.

 So when new Denny’s restaurants are built or older ones are up for remodeling, owners will turn to Cree LR6 LED downlights instead of incandescent, fluorescent or any other kind of LED lights.

Denver Dennys 3 (main 2)

Cree LR6 LED downlights line the ceilings of this Colorado Denny's.

Our LR6 LED downlight is just that. It’s one of those lights you would screw into a recessed can lighting fixture. These fixtures are common in restaurants, retail shops and even newer homes. Start looking up when you’re out dining or shopping and you won’t believe how many dot the ceilings.

Denny’s corporate architect Mitch Riese says our fixture was chosen because of the quality of light it delivers (the last thing any restaurant needs is bad lighting), its long life (it’s designed to last 50,000 hours) and its energy savings (each light consumes only 10.5 Watts).

“We evaluated numerous LED light fixtures from a variety of manufacturers to ensure that we chose the best possible product and partner for this major lighting specification,” explained Riese, corporate architect and senior manager of design & construction for Denny’s. “With the Cree LR6 fixture, we found the best value for our money, helping us deliver beautiful, warm light, while significantly reducing our energy consumption and maintenance requirements.”

One of the believers is Denny’s franchise owner Pete LaBarre. When I first spoke with him a year ago, he had installed 340 Cree LR6 LED lights in four of the restaurants he owns in the Colorado Springs, Colorado area. When we checked back in with him recently he had installed more than 400 of the lights in the dining rooms of his five restaurants. He says his six-inch LED downlights are saving him around $15,500 per year in energy costs alone and that he has seen a payback of between 20 to 24 months, (depending on the electricity provider for each of his restaurants).

Cree LED lights line the ceiling in one of the Denny's restaurants Pete owns.

Cree LED lights line the ceiling in one of the Denny's restaurants Pete owns.

And he’s not stopping there, Pete has decided to replace 500 fluorescent bulbs and tubes with 200 Cree LR6 fixtures, illuminating the perimeter of each restaurant.

“Our lights stay on all the time, so we did a watt comparison of what we had in place before the LR6 downlights,” LaBarre said. “We found that we used 6,000 kilowatt hours less per month in the store that had the Cree fixtures versus the store that had the fluorescent lighting,” he said.

It’s cool to see quality LED lighting is making its way into more restaurants. It just goes to show that LED lighting is ready and that energy-wasting incandescent lights are best used in restaurants for one purpose – as heat lamps keeping your food warm.

Cree’s October LED lighting giveaway featured several lucky winners

Thursday, December 23rd, 2010

It wasn’t easy picking a winner for the October Cree LED lighting giveaway. There were so many bad lighting photos that our selection committee decided to award lights to several runner ups.

The grand prize winner is Mark Rogers of Encinitas, California, who tried to eliminate the energy-wasting incandescent lighting in his home office by replacing it with LED lighting on his own. But Mark chose PAR30 LED spotlights, which aren’t really the right type of fixture for a downlight application.

When I wrote Mark to tell him he won, he said he was excited because “there are evenings when I would love to work just under the downlights.” Well, thanks to the five new warm CR6 LED downlights he won, Mark should be able to get some work done while saving energy.

His new lights will illuminate his office with beautiful light (2700K for you lighting geeks) while only consuming 10.5 Watts each. And his new LED lights are designed to last 50,000 hours, which means he shouldn’t have to change a light bulb for many years.

Mark Rogers October Winner

Mark Rogers won the October LED lighting giveaway with this photo.

But Mark isn’t the only October winner. Our judges had a tough time saying no to a few other entrants. So we gave away two CR6 LED downlights to Dan Leighton of Cary, NC, an energy-conscious homeowner who sent us this picture of his “spooky” bathroom lighting:

Dan's spooky entry.

Dan's spooky entry.

The judges also loved the submission from Garrett Loewenberg, so they decided to help the boy rid his parents’ home of CFLs by giving him two CR6 LED downlights. And, finally, the judges wanted to help Oregon resident David Myrick banish the bad track lighting in his stairwell. So they awarded him three Cree LRP-38 LED lights, which should be a huge improvement over the current set up he submitted a picture of:

David submitted this picture of his dark hallway.

We’ll be announcing the November winner soon. And there’s still time to win our December giveaway. Submit a photo of the bad lighting in your life. Whether it’s at home or work, let us help you fix it! Simply upload your photo here!

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.

outside

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.”

Indiana Tech 1

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.

Cree LR6C LED downlights and LR24 LED troffer lights illuminate the building.

Cree LR6C LED downlights and LR24 LED troffer lights illuminate the building.

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.
