Pegasus Lighting Roundup: Lighting In May

It’s time for our monthly update on the most exciting happenings in the lighting world!

In Lighting News…

According to e! Science News, the new production of dual-color lasers could lead to cheaper, more efficient LEDs. It’s normally very costly and difficult to physically put together several lasers of different colors in one LED, but researchers at Arizona State University are about to change that. Read more.

On May 15, the US Department of Energy issued new protocols for calculating savings from energy efficient home, commercial, and industrial upgrades. The new protocols are voluntary, but formulated to encourage a common structure to determine energy savings based on average efficiency measures. Read more.

Lighting magazine recently published an article by lighting designer James Bedell about lighting CRI (Color Rendering Index). CRI is defined as the measure of how accurately a light portrays color, but Bedell argues that CRI actually has very little to do with how our eyes see colors. Instead, the CQS (Color Quality Scale) proves to be a more accurate measure. Read more.

A new study at the University of North Carolina at Chapel Hill and The Institute for Market Transformation (IMT) found a link between energy efficient homes and morgage risks. It seems that owners of ENERGY STAR-certified houses are less likely to default on their home loans. Read more. (more…)

A lot has been happening in the lighting world lately. Here are this month’s highlights…

In Lighting News…

Turkeys Love LEDs: A Minnesota turkey farmer is using LED lights to keep his turkeys happy and healthy. Every morning, Mike Langmo uses his dimmable, programmable LED lights to simulate a sunrise for his flock. There’s evidence that this practice is helping regulate their circadian rhythms, possibly contributing to their health and well-being. Read how it works here.

LED Prices Dropping: Two months ago, Cree announced they would be selling an LED light bulb for less than $10 in the US. Now, Osram has revealed that their new LED replacement for the 40W incandescent will retail at €9.95 in Germany. With prices going down this rapidly, LED light bulbs are becoming more attractive to consumers. Read more about this event here.

Most Efficient LED?: Philips has also been stepping up their game this month, claiming to have created the world’s most efficient lamp. It’s an LED tube light replacement prototype that produces 200 lumens of pure white light for every watt it uses. Learn the details here. (more…)

Pegasus Lighting Roundup: Lighting In March

Here’s what’s been going on in the lighting world this month…

In Lighting News…

A Wal-Mart store in Mt. Pleasant, Wisconsin has equipped all its indoor and outdoor facilities with LED lights. The areas now illuminated by LEDs include the sales floor, pharmacy, restrooms, stock rooms, and the parking lot. Wal-Mart expects to save at least 30% of their energy costs, compared to their old fluorescent lighting systems. Click here to learn more.

On March 5th “The Bay Lights,” an LED light sculpture, illuminated San Francisco’s Bay Bridge for the first time with 25,000 LED lights. The project only costs $15.06 per night to operate, and was designed by artist Leo Villareal on a laptop. Check out this video from the grand lighting ceremony:

Pegasus Lighting Roundup: Lighting in February

What’s been on the tip of everyone’s tongue this month? One word: quality. From new standards for quality lights, to tips on using light to improve your quality of life, we’ve got you covered. Here are this month’s top stories…

In Lighting News…

Is Color Rendering Index (CRI) the most accurate measure of a light’s quality? With all the innovations happening in the lighting world right now, the Color Quality Scale (CQS) might just be a better judge. CRI measures a light’s performance rendering only 8 different colors. CQS, on the other hand, measures 15, and accounts for other factors like chromatic discrimination and human preference. Click here to learn more about CQS.

In December 2012 the California Lighting Technology Center at the University of California, Davis helped encourage the California Energy Commission to include new standards of quality for LED replacement lamps in its first-in-the-nation energy-efficiency directive. Now, the center is pushing for similar LED standards on a national scale. You can learn more about this initiative here. (more…)

LEDs Allow New Method of Data Transmission

Computer Keyboard  and Monitor
At the University of Strathclyde, researchers are developing tiny LEDs that can deliver Wi-Fi-like internet access. Called Li-Fi (short for Light Fidelity), this system has the potential to transmit data several times faster than what we’re used to.

Professor Martin Dawson and his team created tiny LEDs, each about the size of an end of human hair, which flicker on and off thousands of times every second. By altering the length of these flickers, the lights can send digital information to computers and other electronic devices. Picture it as a sort of digital Morse code.

The micron-sized LEDs are made so small to allow for more data transmission at a faster rate. The university’s LEDs can flicker at a rate 1,000 times faster than larger LEDs. Why? Well, if you have 1,000 micron-sized LEDs, they can fit into the same space as a single 1mm LED. Each tiny LED acts as an individual communication channel, which allows the transmission of about a million times more data.

Suddenly, a large LED display, with each tiny LED acting as a pixel, can also allow internet communications. (more…)

LED Rebates For 2013

Considering switching your commercial lighting to LEDs this year? Learn how to get the most out of lighting rebates and incentives. 

Have you gone shopping for new light bulbs or fixtures lately? If the answer is yes, you’re probably aware that LED lighting options have saturated the market as energy efficient alternatives to incandescent, halogen, and fluorescent lights.

But, what you might not know is that there are tons of rebates and incentives out there for buying LEDs that can help you save money when making the switch.

Since January 2012 the number of rebate programs for LEDs has increased by 54%.

Here’s an overview of the kind of rebates your company can expect in 2013:

Rebate Snapshot LED 1-13

If you’re already familiar with rebates from electric utilities and government organizations in your area, you may notice that the dollar amounts for most rebates have decreased over the past year. The average rebate for an LED replacement lamp has gone down by 7% since last January. Rebates amounts also decreased for LED fixtures: recessed down lights decreased by 66%, accent lighting by 12%, and high bay fixtures by 8%.

You needn’t be alarmed by these numbers, though. They’ve only been adjusted to match the lower prices of LEDs in 2013. Less money is necessary to make purchasing an LED financially attractive. Also, since there are over twice the programs this year, money is even more accessible. (more…)
