Cree and LED lighting are starting a revolution

You can learn how to make gorgeous LED pendant lights

One of the world’s largest lighting tradeshows is wrapping up today in Frankfurt, Germany. More than 1,500 companies in the lighting business exhibited their goods and services at Light+Building. Among the items on display in the Cree booth are these gorgeous LED pendant lights:

These lights were recently crafted by our application engineers to show the world yet another example of how LEDs can be used to make beautiful lights. I haven’t had a chance to chat with any of my colleagues who are working the booth in Germany, but I’m guessing they’re fielding a lot of questions about these beautiful lights.

 How can I be so sure? Well, a few weeks ago two of these lights were installed in our office, and on several occasions, folks from other departments have stopped by to ask about the pretty new lights. And, admittedly, every time I pass this corner of our office, I wish I could snag one to replace the single incandescent pendant light that wastes energy in my kitchen.

So how can you get your hands on one? Well, you can’t – yet. You see, our application engineers created these pendant prototypes to show lighting manufacturers how easy building an LED light can be using one of our newest LED components, the Cree XLamp ® MPL EasyWhite ™ LED. This new multichip LED (we announced it back in February) can shorten the design and manufacturing cycle for new lighting products because the LEDs are specified like traditional light sources. Designers just have to indicate the desired color temperature and brightness, which can save time on learning the ins and outs of what we in the LED industry call binning.

If you look closely, the spiral metal at the top of the glass shade appears to be a decorative feature, but really it’s a heat sink designed to dissipate heat. And while they aren’t a commercial product, these particular pendants were designed to last 50,000 hours. And when used with a frosted white shade, an XLamp MP-L-based pendant can be an ENERGY STAR®-conformant SSL luminaire.

Our engineers made their design notes available for anyone to download. It’s just another way we’re leading the LED lighting revolution.

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.
