Stock Photo Shattered Light Bulb Next Phase Of EISA: Losing The 75 Watt Incandescent
As of January 1, 2013, the second phase of EISA has taken effect, banning the import and production of 75-watt incandescent light bulbs.

For those unfamiliar, EISA stands for the Energy Independence and Security Act of 2007. President Bush signed this act during his second term, and it aims to do the following:

  • Move the U.S. toward greater energy independence and security
  • Increase the production of clean, renewable fuels
  • Increase the efficiency of products, buildings, and vehicles
  • Promote research on and set up greenhouse gas capture and storage options
  • Improve the energy performance of the Federal Government
  • Increase U.S. energy security, develop renewable fuel production, and improve vehicle fuel economy

One of the main goals enacted by this legislation is to raise appliance and lighting efficiency standards, which is what has brought about the incandescent light phase outs. These older incandescent lamps just don’t meet the mark.

Last January, we said goodbye to the 100-watt incandescent lamp, and now the 75-watt has followed. It’s likely you’ll still see them in stores in coming months, but with the ban on importing or manufacturing these lights, the supplies we already have will dwindle and eventually run out. Now, a light bulb must use 53 watts or less if it emits the equivalent lumens of a 75-watt incandescent light.

These new standards are technology neutral, so any kind of light bulb can still be sold, as long as it meets the efficiency requirements. Continue reading »

Diverse and impressive changes have been taking place in the lighting world this month. Read on to discover the fun and innovation!

In Lighting News…

Across the web, there was a consensus that LED holiday lights were the thing to have for the holidays. Not only are they energy-efficient, long lasting, and durable, they can also be interactive. We’ve seen families across the country creating holiday feats – dancing light shows to hundreds of different songs, and even games for visitors to play. For a balanced review of new LED string lights, check out this article from Apartment Therapy.

Speaking of switching to LEDs, NASA is swapping out all of the light bulbs on the International Space Station to help alleviate astronauts’ insomnia. They’re planning to use specially diffused LEDs, which can filter light into different hues. They’d provide blue light to help astronauts wake up in the morning, white light during work hours, and reddish light to soothe them to sleep. To read more on the science of the switch, check out this article from Gizmodo.

A recent article on Forbes.com declared that LEDs have finally “arrived.” In other words, they’re a mature, viable product, widely available, good-looking, and economically attractive. Continue reading »

No light source is perfect. With every different light source come consumers and critics who dislike it. We complain incandescent lights don’t last long enough. They use too much energy, give off too much heat, and then that heat jacks up our A/C bills.

Fluorescents and CFLs last longer, but some people are bothered by the small amount of UV rays they emit. Sometimes they might flicker or take a while to reach full brightness. If they break, they release harmful mercury into the environment.

Even the LED, the lighting industry’s golden boy, isn’t perfect. It lacks the incandescent’s beautiful, soothing light quality. LEDs are still expensive, and it can be hard as heck to make them with dimming capabilities.

Clearly, we still have work to do. But now, there’s a new light source that might just give these other guys a run for their money.

It’s called FIPEL. Doesn’t exactly roll off the tongue, does it? Well, whatever the name, this new light source could be the answer to the comfortable, efficient light we crave.

Light Emitting Diodes 300x198 The Power of Silicon Comes to LEDs
Silicon is amazing. We’ve all seen what those tiny silicon chips have done for computers in the past few decades – they’ve gone from mysterious machines to ubiquitous household objects capable of the stuff of dreams. Now, Bill Watkins, CEO of Bridgelux proposes silicon is about to do the same for LEDs.

Where Silicon Can Take Us

Silicon could revolutionize the solid-state lighting (SSL) industry. It has the potential to make light sources like LEDs faster, cheaper, and more functional.

Current SSL lights like LEDs have already come leaps and bounds ahead of older light sources like fragile incandescent lights, but with silicon, we could see them overcome the light socket completely, and become embedded in stairs, cabinets, and other household fixtures. They could also have added features like motion sensors or color changing abilities, so you can easily alter your home’s mood at will.

SSL Today

So technically speaking, why is silicon so great? Well, since the ‘60s, silicon has dominated high technology. It allows innovators many advantages in creating new digital products because it’s cheap to make, and holds structure well. You can shrink things like transistors without destroying their functionality with silicon.

Currently, light emitting diodes (the semiconductors that generate light inside SSL light bulbs and fixtures) are a rare digital technology that doesn’t rely on silicon. Continue reading »

In Lighting News…

LightRecycle, a non-profit program to recycle lighting products in British Columbia, recently expanded to recycle all lighting products at no charge – the first program of its kind in Canada. The program began in 2010, and it caters to both commercial and residential clients.

Dan Watson, a graduate of the Royal College of Art, won this year’s James Dyson Award for his sustainable fishing net called SafetyNet. This special trawler fishing net uses strategically placed holes and LED lights to separate fish of different ages and species. These illuminated “exit signs” allow smaller non-marketable fish to escape.

LED Mini Guide Lights 300x195 Rise…And Shine That Blue Short Wavelength Light
Kids these days. They haven’t got it easy. According to the Center for Disease Control, almost 70% of school children don’t get their full 8 hours of sleep on most school nights. Whether this is due to heavy workloads, intense extracurriculars, goofing off, or simply having an overactive mind, the resulting problems are the same. Inadequate sleep has been linked to things like depression, behavioral problems, poor academic performance, drug use, and car accidents.

However, a recent study led by Mariana Figueiro and Mark S. Rea of the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute may have found an unexpected remedy for stressed, sleep-deprived kids: blue light.

To understand the study, first we need to know a little bit about the human body.

The Cortisol Awakening Response

The hormone cortisol, produced by the adrenal gland, operates on a 24-hour cycle, helping regulate our bodies navigate in and out of sleep. Concentrations of cortisol reach a minimum at bedtime and a peak in the morning. Levels hit their max in the first hour of waking, this is called the Cortisol Awakening Response or CAR.

Experts associate a high CAR with better preparedness for the stresses and challenges of the day.

So how the heck does blue light factor in? Well, we’ve already seen how short-wavelength light can suppress melatonin to keep you awake at night (read more on that here), so it’s not surprising that it has an influence on us in the morning. Continue reading »

bytelight 300x192 Guiding Lights for the Great Indoors

Image via ByteLight.com

Holiday shopping is already beginning – that time of year when we dart frantically from aisle to aisle trying to find just the right gifts for our friends and family, and to ready our homes for the season. But imagine with me for a moment what it would be like to have your own personal guide to help you map out an efficient route through the store. No more combing aisles to find that perfect shoe-rack, or having to book it the entire length of a Super Target to get that pair of headphones you forgot.

A new startup called ByteLight is working on an innovative new idea for an indoor GPS-like system with the help of LEDs and smartphones. The idea is to have an app or program for the phone that guides shoppers to find exactly what they’re looking for within a store (and even find discounts on products).

Instead of sending a signal out to space like a normal GPS, your phone would connect wirelessly with the LED lights in the store to guide you where you want to go.

For the system to function, the LED light bulb would blast a specially designed light signal to the camera of your smartphone to determine your location. The signal would consist of blinking patterns of light, too rapid for the human eye to notice. The technology would be able to detect a person’s location within one meter, and do it in less than a second.

To get the system to actually work for you, ByteLight’s software would need to be installed on your smartphone and the LED lights would need a special chip to send the signal.

The chip within the LED would be cheap to add, and would use the shopper’s location to help them find their way to the products they want, also delivering targeted ads. Any current smartphone camera would work with the system. Continue reading »

LIFX 300x225 Pegasus Lighting Roundup: Getting Smarter

Image via Kickstarter.com


In lighting news…

Over the past month, I’ve seen so many smart-controlled energy efficient light bulbs popping up on the market, growing what Forbes.com calls “The Internet of Things,” in which objects (and not just people) communicate over the web. Each light bulb has an Internet IP address that you monitor wirelessly with a smartphone, tablet, or computer. Some popular models include LIFX (featured on Light Reading earlier this month), and Philips’ Hue coming to Apple Stores tomorrow, October 30!

According to ThinkProgress.org, New York City was the first U.S. jurisdiction to publicly post energy efficiency information for its building stock last month. A series of mind-numbing spreadsheets might not seem so exciting at first, but this is a key step in establishing energy transparency in the real estate market.

It’s not every artist’s dream to have a 500-foot canvas that’s also an international icon, but that’s what Leo Villareal and his lighting team couldn’t be more thrilled about. This month, crews will begin constructing a massive light-art installation on San Francisco’s famous Bay Bridge.

First conceived 2 years ago by Ben Davis of Words Pictures Ideas (a communications firm that does work for Caltrans), “The Bay Lights” will cover 1.8 miles of the bridge’s northern face with 25,000 programmable LEDs suspended on cables. The team plans to have it finished by March, when they’ll debut it with a grand lighting celebration just in time for the bridge’s 75th anniversary.

Leo Villareal, the artist in charge, plans to use intricate sequences and algorithms to display light patterns based on movements around the bridge. He’s best known for his piece “Multiverse,” made of 41,000 LEDs in the tunnel that connects the two wings in Washington’s National Gallery of Art. Villareal hopes to bring the same elegant orchestration to The Bay Lights. You can see the concept in this video:
