Noribachi LED lighting outshines fluorescents

Noribachi, a smart energy LED and solar lighting company, recently saw its ultra-efficient, cold-temperature-compatible LED fixtures successfully installed by Mark Pereira of CIM Electric at Agro-Jal Farms' new cold storage warehouse.

Agro-Jal, one of the largest farming and cooling operations in California's Central Coast region, has consistently been ahead of the curve with energy efficiency and cooling technology. It has been the exclusive berry provider for the Kentucky Derby horserace for many years. Agro-Jal's cold storage facilities service not only their own produce, but also help other regional farms cool and process their products.

Agro-Jal's new cooler takes advantage of technologies including ammonia-cooled wind tunnels, an ice packing machine originally conceived to make ice for zoo penguins, and the new Noribachi LED fixtures. Combined, these save the facility significant amounts on monthly cooling and lighting energy costs.

Noribachi's HIGHBAY.M fixtures deliver a bright, natural white light that allows fruit and vegetable inspectors to determine ripeness without taking a trip outside, an inconvenience the previous HID lighting had necessitated with its yellow tinge. Noribachi LED lighting is also completely unaffected by the 34 degree F environment, whereas traditional lighting suffers lifetime shortages and turn-on delays.

The HIGHBAY.M fixtures provide so much clean light that in one room Agro-Jal director Eric Gamble was able to scale back from 25 fluorescent fixtures to just seven LED fixtures while achieving superior light output. This not only made the Noribachi system as cost-competitive as fluorescents, but kept toxic fluorescent bulbs away from food products.

"It's only a matter of time before the FDA says we can't have fluorescents anywhere close to food due to their mercury content," said Gamble. "I'm staying ahead of the game by installing LEDs now. Clearly LEDs are the future of food safe lighting. It is an obvious choice."

Most of the LED fixtures at Agro-Jal are also equipped with motion-sensing on/off technology, further reducing energy use. "It's an incredible value for light output versus wattage," said Pereira of CIM Electric, contracted to complete the installation.

With the spring harvest just around the corner at the time of installation, it was imperative for Agro-Jal to finish its new cold warehouse quickly. The Noribachi LED fixtures were more than up to the task. "The ease of installation was an 8 out of 10, and I was very impressed by the quality of the fixture itself. It's really well put together," said Pereira.

LED Companies Look to Expand in the Outdoor-Lighting Market

The LED market looks to be heating up once again, as a drop in prices for LED streetlights may begin to sway local governments to make the switch to the new technology. According to a report put out by the Department of Energy, roadway lighting accounts for 25 percent of the outdoor-lighting market in the U.S. with LED lights making up only a 3 percent share of the roadway market.

"The LED industry has grown in cycles," observed Eric Higham, Director of the Strategy Analytics GaAs and Compound Semiconductor Technologies Service. "The first phase involved backlighting for small consumer devices, like mobile handsets. These solutions have evolved to meet the needs of laptop, television, electronic sign and automotive applications and the next wave for LED adoption appears to be commercial and residential lighting."

Cree, Inc. announced a breakthrough innovation in street lighting with the introduction of the XSP Series LED Street Light -- the most affordable and efficient Cree(R) LED street light designed to speed payback to municipalities. Using nearly 50 percent less energy and designed to last over three times longer than wasteful, traditional high-pressure sodium street lighting, the XSP Series can double the lumens per dollar compared to previous generations of Cree LED street lights and is the ideal choice for cities and municipalities looking to save money and resources.

Rubicon Technology, Inc., a leading provider of sapphire substrates and products to the LED, RFIC, semiconductor, and optical industries, reported fourth quarter revenue of $19.4 million, which was slightly below the range of management's November guidance. Revenue decreased both year-over-year and sequentially, largely as a result of weak demand from the LED market due to excess inventory in the LED supplies chain.

School district to study energy-saving measures

A host of money- and energy-saving capital improvement projects will be up for approval at an upcoming Delaware city school board meeting.

Larry Davis, director of facilities and transportation, on Nov. 7 described to the board projects he expects can lower the district’s energy costs by $226,500 annually. The projects include insulation replacement in 11 district buildings, as well as lighting improvements in nine buildings.

“Every one of the schools is affected first of all by lighting,” Davis said. “(One of) the things that we can do to conserve electrical energy (is work on) the lighting going through our buildings.”

Davis has seen the district through the conversion from incandescent bulbs to fluorescent lights and is now transitioning the district to newer, more efficient lighting. “It’s just a normal progression,” he said. “$115,000 of our annual savings is going to come strictly out of lighting.”

Additional savings could be achieved by replacing the boilers at Hayes High School, which were installed when the school was built in the 1960s, Davis said.

“They’re still in there as we speak right now,” he said. “We’ve done a pretty good job of maintaining them, but it also runs up our operating costs.”

Also at Hayes, Davis said, the district can install a water reclamation system that will allow non-potable water to be used for the building’s air-conditioning condensers.

“We have to constantly run … potable, good water in the tower,” Davis said.

The final costs of the improvements have yet to be calculated. Davis said he would have more concrete figures to present to the board at its next meeting, a work session scheduled for 5:30 p.m. Nov. 28.

Also at the meeting, Superintendent Paul Craft announced the district was awarded two Soar Awards for High Progress from Battelle for Kids.

The first is the most-improved award. “The district itself is being identified as among the top five of all (135) participating Soar districts,” Craft said.

In addition, Hayes High School is receiving an award for its improving student test scores.

The awards will be presented at a ceremony Nov. 14 at the Greater Columbus Area Convention Center.

Sculptor creates a fantastical world

The drive up into the hills north of Enderby is blasted with colour –– Douglas maple, Western larch, Black cottonwood dot the landscape as the road twists and turns.

For Stephan Bircher who calls this area home, it’s a perfect burial landscape for creatures large and small to find their final resting place. He has spent many hours digging through the dirt and lifting up rocks to uncover these delicate remains among other treasures that nature has left behind.

The glassy wings of butterflies, feathers, shriveled leaves, abandoned shells, even road kill, have all entered the realm of Bircher’s mind and eventually into his studio.

A sculptor, lighting designer, theatrical wunderkind, and alchemist when it comes to fusing nature with human-made objects, Bircher could be considered a kind of mad scientist or a post-modern Jim Henson.

Far from being a “Muppet” lab, his studio is a fantastical place where lit up skeletal creatures spin like whirling dervishes and play musical instruments, their intricate parts held together by magnets, springs, cogs and cranks, and run by small motors.

“I like to take the magic out of my surroundings; that’s how my sculptures develop,” said Bircher. “The bones in my work, and whatever else I find out here, come from my youth of always going out into the wilderness. When I was walking around I would always see things a little differently, of what could be made from nature.”

Growing up near Basel, Switzerland, Bircher says he was always tinkering when he wasn’t rebelling.

The son of a surgeon, he says his parents had high hopes for their son, but Bircher preferred drawing cartoons in his sketch book than attending to his academic studies.

“I had an endless struggle in my school days,” he said. “I found what I wanted by myself, sometimes it was negative. I was not always matching what was expected of me. But I was always drawn to creativity.”

On family holidays, Bircher would go to the house of his aunt in the mountains, where he would make fantasy villages out of things he would find.

“They were more abstract, while my brother made functional steamboats,” he said.

After high school, Bircher travelled to India on what was supposed to be a short holiday. He ended up staying two years.

India was everything Bircher’s upbringing wasn’t: crowded, noisy and chaotic.

“I think it’s this experience, out of my family who were open-minded but always tried to make things organized, that shaped me. I loved it.”

After returning home to Switzerland, Bircher would eventually go on to teach at a day school. His subjects were handicrafts and sports. He also helped his students with numerous extracurricular projects such as hand-building a unicycle.

Unleashing the inner beast with hard-court bike polo

Ah, polo—the sport of kings! When it first emerged in Central Asia hundreds of years ago, elite cavalry units would play polo as a military training game. In the sixth century, even the king of Persia was known to take on the queen and her ladies.

And yet, who but a royal can afford a horse? As time went on, the game grew to be more egalitarian. In 1891, pioneering Irish cyclist Richard J. Mecredy swapped the horse for a bicycle, and bike polo was born.

Today, bike polo is a people’s sport. Teams play regularly in cities around the world, competing in tournaments and maintaining friendly rivalries. Pickup games are played every week; all you need is an old beater of a bike, a helmet and a wheel guard to protect the spokes from getting mangled.

Every Thursday at 7 p.m., bikers roll up to the Golden Hill Recreation Center to play hard-court bike polo (held on hard ground rather than a grass field) beneath the lights of the basketball court (or the handball court, if the hoops court’s being used). In case anybody wants to join in, Mike “Lawnmower” Maverick always shows up with an extra bike and a big bag of mallets, the waist-length sticks used to control the ball.

Companies like EighthInch sell polo-mallet kits, and there’s even a bike polo iPhone app, but many players prefer to fashion their own gear and customize their bikes. Trevor “Fraggle” Fray, a bike messenger whose dreadlocks were sticking out of a helmet covered with stickers (“dirty hippie,” one reads), rides a ’cycle with a stiff, mountain-bike frame and both front and back brakes hooked to his left-hand brake lever, leaving his right hand free to wield his mallet. Renee Green went one step further by simply hacking the right handle off her handlebars.

Maverick’s mallets are home-made—hockey poles or bamboo rods affixed with cylindrical heads made of plastic piping. On one, the end of the head was plugged with a piece of cutting board. It’s kind of like “knights making their own swords,” he explains. “You make it in your garage, and it’s like your own design, and you bring it to the court, test it out against the other knights.”

Unlike L.A.’s thriving bike polo scene, San Diego has only about a dozen regular players. They started holding games three years ago; Jordan Green (no relation to Renee) says they would often spend more time looking for a court than playing. When they appealed to the city, they were given four orange cones to use as goal posts.

Only about four players had shown up when I headed to the Golden Hill Recreation Center around 7:45 p.m. on a recent Thursday. Usually, they play in teams of three, with matches going to five points. Fray started calling friends to round up another player for a proper game, and, finally, a quiet fellow named Josh Montonavous rolled up. The game was on.
