Long-life LED Light Bulbs Released by Toshiba

It is announced from Toshiba Lighting & Technology Corp. that its long-life LED (light-emitting diode) light bulbs will hit the shelves on July 15, 2009.
A 6.9-watt and a 4.1-watt light bulb will be available for 5,460 yen and 5,250 yen, respectively. Their lighting levels will be equal to 60-watt and 40-watt regular bulbs.
The lifespan of the LED light bulbs is expected to be about 40,000 hours per unit, about 40 times longer than regular bulbs.
Although the long-life LED may seem expensive, an official from Toshiba said the LED light bulbs will greatly reduce the carbon dioxide emissions and electricity costs.   www.bgocled.com

The First Purely White LED Produced in Korea

It is claimed from Korea Researchers that the world’s first purely white LED (light-emitting diode) has been produced in Korea.
Soo-Young Park, a professor of organic materials for photonics at the Department of Materials Science and Engineering at Seoul National University in Korea, led the group, which includes researchers from the University of Valencia in Spain.
LEDs are much more energy-efficient than incandescent or compact fluorescent lightng (CFL), but the quality of light they can give a room is up for debate.
Because LEDs do not naturally produce white light, getting them to look like they do adds to their production cost, making them much more expensive than your average incandescent or CFL. Many companies have been trying to come up with different LED recipes and components to produce a nice white light, while keeping the consumer cost down.
Park and his group claim to have engineered a molecule with one orange and one blue light-emitting material that produces a white light in the visible light spectrum when put together.
In other words, they say they’ve invented a white-light-emitting diode.
Repeated laboratory tests apparently showed that the new form of LED molecule is efficient, color stable, and able to be reproduced again and again, making it a legitimate candidate for use in LED lighting.
A detailed explanation of the group’s molecular work can be found in the current issue of Journal of the American Chemical Society.
According to Mr.Park and his group in their paper, an ideal material for a white-light source should be cost-effective, stable, robust, emit over the whole visible spectrum, not suffer from self-absorption, and its pure color should be easily reproducible. With this goal in mind, we have successfully synthesized and characterized, for the first time, a white-light-emitting single molecule dyad, consisting of two noninteracting chromophores showing excited-state intramolecular proton transfer.  www.bgocled.com

LED Waves in Baltimore This Week!

LED Waves just wrapped up the Building Energy 11 conference and trade show in Boston and our next stop this week is the Baltimore Convention Center for NFMT. We’ve exhibited with NFMT before and we’re really excited about returning this year. The show offers exposure to high-profile individuals in facilities management, plus there are always cool interactive exhibitions going on. If you’re headed to Baltimore for the show, it would be great to see you! We’ll be at NFMT booth #1479, March 15-17. In the spirit of facilities management, we’re showcasing some of our top sellers for professionals in this field. Among our favorites is the Madison High-Power LED Aluminum Light Bar. We like it because it’s hard working – even at a mere 12 Watts, it’s one of our brightest LED light bars – but it’s also on the more stylish end, with its sleek aluminum casing. The Madison High-Power LED Light Bar comes in 22’’ units (12 LEDs total), but up to three of them can be soldered together. The Madison emits about 3’ of visible light, and it can be dimmed with a separate dimmable LED power supply. Today’s Facility Magazine also thinks highly of the Madison LED Light Bar, as they featured it in the Product Focus section (Page 33) of their January issue. TFM notes that this lamp is ideal for “replacing high heat lighting in display and museum cases, and inconspicuously creating bright retail spaces.” Whether you’re looking to illuminate a commercial or residential space, LED Waves has a great retrofit or customized LED lighting solution for your project! Give our sales team a call at 1 800 986 0169 to hear about products and availability, get pricing by quantity, or just to learn more about LED technology. And if you’re in Baltimore this week, swing by NFMT and head to LED Waves booth #1479. We’d love to see your face.

NEW Clearance Items: MR-16 LED Light Bulbs

Our guys are back from Baltimore and they're reporting that NFMT was a huge success, not to mention a lot of fun. It was great speaking to so many fellow professionals in the green sector. Thank you to everyone who stopped by our booth! In the midst of spring cleaning, the LED Waves warehouse has set aside some overstocked items that we can now offer at new lower prices. Among the drastically cut products are a few models of MR-16 LED light bulbs. For those who are unfamiliar with this term, MR-16s are small bi-pin light bulbs designed for low-voltage systems. We're seeing a growing number of these, as well as other alternatives to E27s, as the more disposable Edison-style lamps are being slowly phased out. The Corinth is a 3 Watt LED MR-16 containing 3 High-Power LEDs. It's rated to last 30,000 hours, which means way fewer halogen bulb replacements (not to mention fewer trips up and down the ladder to reach high-up fixtures). With its cool white color temperature (5K) and outstanding color rendering, the Corinth LED light bulb would be a great asset in a gallery or any retail display application. Originally $23.55 / Now $13.95 Another LED MR-16 clearance option is the Thebes LED Light Bulb. Available in warm white, this is a solid 5 Watt replacement for the 20 Watt halogen MR-16s you usually see in track or cable lighting. (Check out our affiliates at   www.bgocled.com
