Astronauts in space. New research shows a fresh lighting scheme could help astronauts sleep better, and oh boy, do they need it.

Astronauts are allotted 8.5 hours for sleep out of every 24, but they actually average about 6 hours a night. Their leisure time is prone to occasional disruptions (emergency or docking procedures), plus there’s a new sunrise every 90 minutes, and of course that whole weightlessness thing. On month and even year-long missions (like the speculated 3 year voyage to Mars), it’s pretty darn easy to get frazzled.

When NASA announced they were planning to switch the space station’s outdated fluorescents to LEDs, Dr. George Brainard, a professor of neurology from Thomas Jefferson University, had a few ideas. Not only would the LEDs be more efficient and longer lasing than fluorescents, they could be beneficial for astronaut health. Continue reading »

The London Olympics are certainly on the tip of nearly everyone’s tongue (and Twitter account) at the moment, but did you know there used to be many different kinds of Olympic competitions? From 1912 to 1952, the Olympics featured art competitions in fields like literature, painting, sculpting, music, and architecture. Check out this little goody from the 1948 London Olympics:

1948 Gold Medal Etching

This piece, entitled “Swimming Pool” by French artist Albert Decaris won gold in the Engravings and Etchings competition.

In 1949, the International Olympic Committee decided to stop all art competitions, reasoning that it was illogical to let professional artists compete, while only amateur athletes were eligible. Instead, cultural festivals replaced the art competitions, and still do to this day. There’s still a chance for the best of the best artists and entertainers to showcase their stuff on an international stage, and for lighting designers, this is certainly a world class exhibition.  Continue reading »

Ah…the possibilities. In our July lighting roundup, we mentioned The Clean Revolution campaign, launched at the 2012 Rio+20 Earth Summit in Brazil. The campaign is advocating a massive scale-up of clean energy and infrastructure, along with smart technologies and design. In the next 3 years, The Clean Revolution plans to raise awareness about the success of low-carbon transformations.

The great minds at The Clean Revolution recently created this informative infographic about how much energy we can save with LEDs. We think it’s worth sharing.

LED Light BulbLEDs are everywhere. Over past years they’ve crept into our cell phone screens, the headlights on our cars, the display boards in our favorite sports stadiums, and even into our household light sockets.  With their minimal energy consumption and extra-long rated lives, these babies are on the rise. But in this heyday of LED innovation, have you ever wondered how they came about?

Disclaimer: the history of LEDs is crazy.

(But what would you expect for a light source that we use to light our streets at night AND zap the tattoos off our arms?)

In the beginning was Henry J. Round, a British experimenter at Marconi Labs. In 1907 he was unsuspectingly at work on a cat’s whisker detector for radio made with carborundum (SiC) when suddenly he witnessed a yellowish light—and lo! it was electroluminescence. With increased voltage the light turned brighter yellow, then green, orange, and finally blue. Round was so stoked he wrote a letter to Electrical World about it, and then went back to his radio.

We’ve been in business since 1993, so we’ve heard just about every question in the book when it comes to light sources. “How much longer does an LED light last than a fluorescent, on average?” “Which light sources are dimmable?” “What exactly is xenon lighting?”

We created this infographic to address those questions and more – all of the FAQ’s that we hear related to choosing a light source. You’ll find an overview of how each one works, a color temperature comparison scale, pros & cons, estimated lifetime, and a few more general tips. Let us know what you think!

Want to embed this infographic on your own site or blog? We’d love that! Copy & paste the embed code below:

The Department of Energy just published a new report comparing the life-cycle of LED, compact fluorescent, and incandescent lamps.

According to the report, CFLs and LED lamps are very comparable in terms of average energy consumption. They both use about one-fourth of the energy that incandescent lamps do.

However, the energy used to manufacture an LED lamp is expected to fall significantly in the next several years (see the purple pie charts).

What do you think … Is this what you would’ve expected to see? I was surprised to find that LED and CFL were neck and neck; I would’ve expected LED to win out in low energy consumption.

Imagine your lighting wall switch becoming obsolete.

Imagine controlling every single feature of your lighting from your Smartphone: dimming an individual light or a set of lights, turning them on/off, setting up a timer, and even tracking energy usage in real-time.

In Japan, that’s becoming a reality. Tokyo-based lighting tech startup Net LED Technology Corp has developed the first cloud-based LED lighting system.

It will go on sale in Japan February 20. The lights are 40W LED tubes with a 40,000 hour lifespan, and they come with built-in Wi-Fi. It’s possible to control the lights from a smartphone, tablet, or computer.

For more information, see the feature in TechCrunch or view Net LED Technology Corp’s English site.

Julia Silverman and Jessica Matthews first began thinking about the power of a soccer ball for a college project. Challenged to come up with a solution to a problem facing the world, they focused on the lack of access to electricity in developing countries. Their imaginary solution was a soccer ball that harnessed kinetic energy from play and transformed it to electrical energy to power an LED lamp.

Little did Silverman and Matthews know that 3,000 of those electricity-generating soccer balls would eventually be delivered to Mexico, Haiti, El Salvador, Costa Rica, and South Africa. This is a pretty incredible story:

The holidays are right around the corner, and we are excited to be offering a line of energy efficient holiday lights this year.

Before you stock up with the same old incandescent holiday string lights, consider that LED holiday lights…

  • … Use 90% less energy.  Put a little money back in your wallet when the power bill comes around.
  • … Last 10 times longer.  Avoid the annual trip to the store to replace yet another light string.
  • … Are cool to the touch.  Cross “Christmas tree fire hazard” off your list of worries for the holiday.

Have you ever used LED holiday lights?  Do you plan to this year?

The U.S. will be turning over a new leaf in overall electricity consumption thanks to LED lighting.

I attended a webinar about LED lighting last week and learned some interesting facts about what the future holds for this incredibly efficient light source.

Already, LED lighting has far surpassed incandescent, halogen, linear fluorescent, and high pressure sodium lighting as far as efficacy (a measure of efficiency for a light source, expressed as light output, or lumens, per watt of electricity used).

The expectation is that LEDs will continue to dramatically increase in efficiency and to simultaneously dramatically decrease in cost. Lighting designer Joseph A. Rey-Barreau led the webinar, and he noted that most other lighting technologies are on the edge of their potential as far as efficacy. However, there seems to be no limit to LEDs on this front.

Another interesting gem from the webinar came from a few charts analyzing electricity consumption in the United States. Rey-Barreau noted that if the U.S. had maintained the status quo with previous light sources, electricity consumption would double in the next ten years.

However, thanks to LED lighting, we are expected to actually drastically reduce electricity consumption in the next ten years. LED lighting will likely reduce lighting energy use in the United States by one-fourth by 2030!
