Cree and LED lighting are starting a revolution

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.

Plein air painter wins March LED lighting contest, plans to put lights in his studio

Thursday, April 22nd, 2010

On Earth Day we’re celebrating our efforts to spread energy-efficient LED lighting. Here’s the story behind the March Cree LED lighting contest winner. You can celebrate Earth Day by submitting a photo for a chance to win five Cree LED lights in our April giveaway.

To say that Gary Bradley’s passion depends on good lighting would be an understatement. Gary is a plein air painter, who spends much of his creative time on location, painting landscapes and buildings on 8×10 canvases. When he’s finished with his small paintings, he takes them back to his Raleigh, NC, studio and paints a larger picture.

Once he’s back indoors, the lighting struggle begins:

“As a painter, one of the things that you have difficulties with is getting lighting in an interior studio,” Gary said. “You end up with all these shadows and the lighting is uneven, especially with fluorescents. So you have to put cool light in and warm light in.”

But Gary is about to win his battle against uneven lighting. Gary is the winner of Cree’s March LED lighting contest. He won five Cree LR6 recessed LED lights, which he plans to install in the studio he is building in his new home. Here’s his winning photo entry:

March Winner

Gary’s new Cree LED downlights will cast a warm, even light in his new studio. And, when I called Gary to chat about his prize, he pointed out another perk to the lights he won – they don’t contain toxic mercury like the fluorescents he was using.

“In the art world, we work with a lot of materials that are toxins, so you try to find different ways to be friendly to the environment,” Gary said, adding that he likes that LED lights are mercury free.

It was good chatting with Gary and learning about his passion for painting. He left me with this thoughtful quote.

“We live in a world where a lot of things are broken,” Gary said. “The environment is broken, personal relationships are broken, so people need beauty to heal themselves. Art is one of the ways we express beauty.”

Want me to write about you next month? Enter the April LED lighting giveaway for your chance to win five Cree LED lights. To enter the contest, simply submit a photo of bad lighting in your home, office, studio, or wherever you spend your poorly lit days. Happy Earth Day!

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:

January LED Lighting winner will light up renovated Habitat for Humanity office

Thursday, February 11th, 2010

When I e-mailed Wanda Ellis to tell her she won the January LED Lighting photo submission contest, she sent me back an e-mail that warmed my heart.

Wanda is the Director of Development for the Caldwell County Habitat for Humanity in Lenoir, NC. She explained that the area’s population means the Caldwell County chapter is small compared to some of the other affiliates of the national nonprofit organization. The Caldwell County Habitat traditionally helps move 7 to 9 families from poverty housing each year, she said.

“This is done through a partnership process that enables families to learn, grow, and build while earning sweat equity for their own future home.  It is not just a matter of building houses, but building lives along the way,” she wrote. Here’s the winning entry:

Future Restore

The five Cree LR6 recessed downlights she won will actually be used in the Habitat’s main office, which is undergoing the renovation. Here’s what she wrote on her photo submission:

“Caldwell County Habitat is in process of renovating an “ailing” old building that will house our offices and our ReStore. We’re basically starting from “scratch” on lighting. We need your help!!!!”

The LR6 offers big energy and maintenance savings and a long lifetime. Just how long? Well, the LR6 is designed to last 50,000 hours – that’s five times the life of the best compact fluorescent bulbs. And her new LR6 LED fixtures consume just 10.5 Watts of electricity each and are dimmable to 20 percent. That can add up to real energy savings for an organization that can help more people with each penny it saves.

We’ve already received a lot of good entries for the February LED lighting giveaway. If you’d like to enter, submit a photo of bad lighting in your home or office here.

Washington-based nonprofit wins five Cree LED lights in December photo contest

Thursday, January 7th, 2010

Having your own office is pretty sweet. You get a door that you can close while you’re at work. An office provides a level of privacy many cubicle dwellers crave. So what if your cube was turned into your office? You’d probably be pretty happy, right? That’s what happened to Mark Wickman, who works for the nonprofit Opportunity Council in Washington.

Mark is the winner of the December Cree LED Lighting photo contest, winning five LED lights for his office. In Mark’s photo, he showed off his new office, which used to be two cubes, but they were torn out and converted into an office. The new construction meant he was “escaping dreary fluorescent ceiling tube fixtures” outside his office, but he really wanted some energy-efficient LED lights for his new digs.

December Winner

Mark is the production manager for the weatherization department at the Opportunity Council, a nonprofit that helps homeless and low-income families learn to become self-sufficient. I asked him to describe the lighting in his office now and he wrote: “mostly ceiling fluorescent tubes – dreary – with a few CFLs which provide no better light quality.”

Mark says the only LED lighting he’s ever tried before was in Christmas lights, flashlights and his bike light. I can’t wait until Mark screws in his new Cree LED lights. He chose our LRP-38 lamps (see photo below), which have a color rendering index (CRI) of 92. The CRI characterizes light sources ability to render colors accurately and can be between 0 and 100. A higher CRI means that colors are more true and the light is perceived as more pleasant. The CRI of fluorescent tubes is often around 72. So Mark is in for a change!

LRP38

A couple of other facts about Mark’s new LED lights … The Cree LRP-38 lamps are designed to last 50,000 hours. That means they could last 17 years if he keeps the lights on 8 hours a day, 7 days a week! And each LRP-38 uses 12 Watts of energy, but provides the equivalent light of a 50 to 90 Watt halogen bulb. So his new lights will also consume significantly less energy than traditional lighting!

Are you starting to get jealous of Mark? Don’t bother. Just snap a photo of bad lighting in your home or office and enter our January contest. We’ll be giving away five more energy-efficient Cree LED lights at the end of the month. You could win next!

Sacramento guitar shop owner wins five Cree LED lights with photo submission

Tuesday, December 1st, 2009

It’s hard to be inspired under bad lighting. Seriously, if you’ve ever worked in a place with dim, greenish or too bright lights, you probably know what I’m talking about.

But each month Cree tries to change that for one lucky person by giving away some of our beautiful LED lights in our monthly photo contest. The November winner is Dave Lynch, a Sacramento, Calif. business owner who has been putting with fluorescent lighting for over a decade.

He sent us this photo, where you can see one of his fluorescent tubes burned out above his head and wrote: “I’ve got these horrid fluorescent lights overhead, been here 13 years, and they’re making me old! What can I do??? Help!!!!”

guitar winner dave

Anyone who uses four exclamation points is probably at their wit’s end. Dave’s entry earned him five Cree LED lights. He chose our LRP-38 lamps. His new LED lights won’t reverse the aging he says his horrid fluorescent lights caused (sorry, Dave), but they will help him save energy while also making the colors in his store pop.

I e-mailed Dave to tell him he won and included some links about our lights. He quickly wrote me back, using even more exclamation points! Looks like he did his research (and has a future in marketing if he gets bored with his guitar shop), because here’s what he wrote me:

“The lamps, the LRP-38’s would give us a huge head start in creating the basis for a beautiful energy efficient and attractively lit shop lighting system worthy of the 21st century.”

I can’t argue with that. In fact, consider this:

  • The Cree LRP-38 lamps he won are designed to last 50,000 hours, which means they could last 17 years if he keeps the lights on 8 hours a day, 7 days a week! Can you imagine not changing a light bulb for 17 years?
  • Each LRP-38 uses 12 Watts of energy, but provides the equivalent light of a 50 to 90 Watt halogen bulb. So his new lights will also consume significantly less energy than traditional lighting!

  • His new lights will provide beautiful, warm light and make the colors in the merchandise pop. Here’s why (be patient, I’m going to get a little geeky on you, but this is truly interesting and information you can later wow your friends with):

The ability to make colors look true – that is to have a tomato look like a tomato – is called color rendering. The color rendering index (CRI) characterizes light sources in view of their ability to produce “natural light” and can be between 0 and 100. A higher CRI means that colors are rendered more naturally and the light is perceived as more pleasant. The CRI of fluorescent tubes is often around 72, but the Cree LED light that Dave is receiving has a CRI of 92! His guitars can look stellar under his new true light.

After he found out he won, Dave e-mailed me some additional photos showing the icky lighting in his shop. Take a look:

I have to say it’s pretty exciting to give away LED lighting to someone who is so enthusiastic about it. You have a chance to win each month. Just submit a photo showing off bad lighting in your home or office.
