Cree and LED lighting are starting a revolution

It’s not just about the light bulb: How Cree is bringing LED lighting to a socket near you

Monday, November 15th, 2010

Fair Question: When is the world going to get an LED light bulb? Of course most people are thinking about a 60-Watt incandescent equivalent when they ask this.  In lighting-speak, that style is called an A-Lamp. It’s fair to say that the general public is pretty obsessed with A-Lamps—because, of course, most of us have a few boxes of them stored in a cabinet somewhere, ready to be screwed in the next time one burns out.

It’s also a question that Cree CEO Chuck Swoboda says he gets from nearly every person he talks to about LED lighting. When Chuck relayed this common question to Cree shareholders a couple weeks ago during our annual shareholders’ meeting, I know many of them were wondering the same thing. So how does he answer the question?

“The answer is: It’s not about the light bulb,” he said. “Yes, we are going to do things to enable companies like GE and others to do the light bulb. But at the end of the day, although (the A-Lamp light bulb) is what we all think about, this represents only about 10 percent of the market opportunity.”

If you’re reading this and you’re thinking: “How can it not be about the light bulb? The bulb has been around for 130+ years. It’s even the universal symbol for a great idea. How can LED lighting adoption not be about that familiar bulb?”

Well, consider this: Light bulbs only make up a small fraction of the $108 billion worldwide market that Freedonia Group estimates for 2010 for lamps and lighting fixtures—around 10 percent of the residential market, to be more specific. So even though many of us think of plain-ole-light bulbs when we think of light, there is an entire industry of lights (and other types of bulbs) that are consuming the vast majority of the energy used for lighting. Think about all the streetlights, office lighting, gym lights, etc. that are on a lot more than your bedside lamp or even your kitchen lights. It’s those markets that must fundamentally change, Chuck said, if we’re going to spread widespread adoption of LED lighting.

“If we’re truly going to change an industry and convert people to LED lighting, the light bulb will eventually become completely irrelevant,” Chuck said. “It only exists because it breaks all the time and you have to replace it. Fundamentally there’s no reason to have a bulb when the LED lasts as long as the rest of the lighting fixture. And so while we will do things to move the market, we will do things in this area because it does change consumer perception, it is just a step toward really changing an industry.”

I know many of us are still attached to that regular, old light bulb. But the next time you’re out shopping or dining, look up at the lights shining on you. Chances are you’re not going to be seeing a lot of A-lamp style light bulbs.

So while we’re finding lighting solutions to the billions of sockets out there, why don’t you start spending some time planning a memorial for the incandescent light bulb. Maybe a time capsule would be a fitting tribute. When your family digs it up generations from now, it will be like finding a box of old records in the attic. Then you can gather everyone around and tell them about how you were once a revolutionary in the LED Lighting Revolution.

Here’s why the new Lighting Facts label is important for consumers

Tuesday, June 29th, 2010

It’s official. New “Lighting Facts” labels are coming to U.S. light bulb packaging in mid-2011. Watt’s up with that? (Sorry, couldn’t resist). Well, the new labels mandated by the Federal Trade Commission mean many consumers may finally start to put “Watts” in the right context.

The Lighting Facts labels will emphasize lumens as a measure of light output instead of Watts. A graphic on the front of bulb packages will display how many lumens a bulb delivers. The back of the package will have additional information on Wattage, color temperature, etc. This change to the packaging will push people to understand that Watts measure energy consumed and lumens measure light output.

This is important because as more energy efficient lighting options (such as LEDs) are sold at the store, consumers can no longer judge the brightness of a bulb based on Watts.

Here's a look at the new labels approved by the FTC.

Back when incandescent lights were the only thing on the market, you could pretty much judge what type of light output you would get based on the Wattage (even though, it’s not the right way to measure the type of light you’ll be getting). It was safe to assume that the higher a bulb’s Wattage, the brighter it would be.

But now that energy-efficient lights such as CFLs and LEDs are taking up shelf space, many consumers must be weaned off their old shopping habits and become familiar with lumens as a measure of light output.

For example, the average 40W incandescent bulb has a light output of about 500 lumens. But a CFL that puts out 500 lumens might only consume 10 Watts. And an LED light that produces 500 lumens can consume even fewer Watts.

Other features of the new labels include:

  • Wattage: You’ll still be able to see how much energy your light consumes
  • Estimated yearly energy cost: That way if you’re spending more on the up-front cost of an energy-efficient bulb you’ll be able to gauge estimated savings to see the true value.
  • Life based on three hours of usage a day: Since Cree LED lights are designed to last 50,000 hours, their life expectancy would be more than 45 YEARS if used for only three hours a day.
  • Light Appearance: There’s a scale measuring the light from warm to cool, including the specific color temperature.  No more guessing whether soft white means warm or cool or somewhere in between.
  • Mercury Alert: Bulbs that contain mercury (ah hem: CFLs and other fluorescents) will be required to disclose that on the package, and include a link to the Environmental Protection Agency’s site that details how to clean up a broken mercury-laden bulb.

The new labels are exciting because they’re really setting the stage for the LED Lighting Revolution.

“The new labels that focus on brightness in lumens will help consumers make purchasing decisions as they transition to more energy-efficient types of bulbs,” according to the FTC press release.

Do you think the new label will do a better job of educating consumers on light output v. energy consumption? Or will the new labels just confuse shoppers?
