Despite a slumping economy, new store venue is seen as smart strategy by a lighting store in Fort Myers, FL.

The roughly $3 million building will offer a host of improvements over the current location, including a two-story atrium for grand chandelier displays, light lifts in the ceiling - a motorized apparatus that allows chandeliers to be lowered to eye level - and a customer service area separate from the showroom.

LED Signage Attracts Consumer Traffic

The exterior will be highlighted by a roughly 35-foot-tall electric sign with a 9-foot by 14-foot LED screen that can be used for advertisements and demonstrations.

In response to the downturn, the Bebbers have tightened their credit policies, reduced overhead through such things as cutting energy usage by using fluorescent display lighting and dramatically increased retail advertising. The additional advertising has meant a boost in retail trade over the past year, as has a moving sale that began in January.

Sector Marketing Strategy Shifts to Consumer Remodeling

"We felt a lot of people would keep their money and turn to remodeling and home improvements, so we started marketing to them to try and make up for the lack of the volume-builder business," Chuck Bebber said.

Today, retail customers represent about two-thirds of the store's business, a position commercial customers occupied before the advertising blitz.

Auxiliary Lighting on Motorcycles

Auxiliary lighting on motorcycles

The "Night-time Awareness - Auxiliary Lighting" bill unanimously passed through the Maryland Senate  and the House in April 2008. This Motorcycle lighting legislation enables the front, rear, and sides of bikes to be illuminated using non-outwardly projecting lights. The bill was publicized to raise awareness for the National Highway Traffic Safety Association's motorcycle awareness week.

"Most motorcycle accidents involving another vehicle, they are almost always the fault of the other vehicle, and usually the comment of the other vehicle is, we just didn't see him."

Police Sgt. Dave Ennis adds that "Anything that adds to the visibility of the rider, I think is a move in the right direction."

A new smokeless lighting technology that is set to replace pressure lamps used by Omena (sardines) fishermen in the 400 million-year old Lake Victoria is now available in Kenya.

Besides being handy for use, LED lighting technology is brighter than pressure lamps and is free from paraffin spillage that has dogged the lake for many years.

Unlike before when fishermen used over five pressure lamps to catch plenty of fish,  new technology now enables them to use only one source of lighting. 

Supplied by Osram Energy Hub, a German based firm, the rechargeable lamps are expected to cut paraffin spillage into the lake by 100 percent once adopted by all fishermen.

The move is expected to protect the aquatic life of more than 500 endemic fish species. Other low power devices such as radios and mobile phones can also be connected this battery box and recharged.

The firm also has complete luminaries such as the Osram O- lamp 2 in 1 which comprises an energy saving lamp that has an integrated battery that is recharged or exchanged at the Hub as a separate unit. 

The firm is collaborating with solarworld AG and the cell phone manufacturer Nokia and plans to cooperate with Siemens to provide water treatment systems after the pilot trial.

"In a restaurant -- where people must look as aesthetically pleasing to each other as the food does to them -- the quality of light is crucial - the type of fixture and the kind of light they produce," says Re:Vision's Jeremy Avellino, an architect/designer and former builder.

For now, he has chosen compact fluorescents (CFLs) that cast a surprising bluish light. They'll use nearly one-quarter the energy incandescent bulbs would and will last 10,000 hours or more.

CFLs produce varying shades of white light, identified by color temperature measured on the Kelvin scale, according to the Environmental Protection Agency's Energy Star Web site (www.energystar.gov). Lower Kelvin numbers mean the light has a warmer color; higher numbers mean the light has a cooler cast. But not all manufacturers list color temperature on their packaging.


Most CFLs on the market offer soft or warm light (2,700K to 3,000K), comparable to an incandescent, that will enhance warmer room colors such as red, yellow and orange, the Web site says. At higher Kelvin color temperatures (3,500 to 6,500K), CFLs will emit more white to bluish-white light that enhances cooler colors (blue, green, violet).

"Our eyes have been tuned to incandescent bulbs for years," Avellino says. "After you get used to compact fluorescent . . . people look better."

But even in mid-renovation, decisions are being reconsidered at the White Dog. The CFLs are an interim step, to be replaced ultimately with light-emitting diodes (LEDs).

LEDs are Environmentally Sound, Use Less Energy, and Last Longer

LEDs are the next wave because they are more environmentally sound, use less energy and last longer than both CFLs and incandescents, Wicks and Avellino say.

LED Colors are Endlessly Creative!

And the light they cast allows for any number of tones and moods. "You can totally name your color," Wicks says.


LED Lights for Exterior AND Interior

Though she is starting to use LEDs in exterior lighting, as the technology advances Wicks plans to use them inside, too - they are easier to dim, an important feature for a restaurant.

Don't Stop with Creative Rays -- Create Environmentally Friendly Fixtures, too!


For environmentally aware designs, he uses life's flotsam and junk: old brass instruments, discarded crystal candy dishes, colanders, antique glass jars, car and motorcycle parts.

Being ahead of the game in repurposing what's available is what led developer Tony Goldman to Muller's door.


Goldman Properties helped create New York City's SoHo district and Miami's South Beach from once-trashed warehouses and old hotel spaces. In Philadelphia, he's taken on a once-worn-out area of South 13th Street between Locust and Chestnut.

Cree Survey Finds Growth of LED Lighting is Escalating

The LED industry is expected to boom on the adoption, deployment and benefits of LED lighting by the end of this year, according to an independent survey conducted at the Hong Kong International Lighting Fair.

The survey, conducted by solid-state lighting components marketer Cree, found that LED lighting will become the most commonly used in offices, parking garages and residential outdoor applications.

The survey confirms a strong global demand increase for LED lighting products. It reveals that, globally, an increased awareness is developing around the benefits of energy-efficient LEDs. According to Cree, this indicates that the adoption trend should continue through to the end of the decade.

The survey found that nearly three-quarters (72%) of the respondents have experienced a growth rate in excess of 20% for LED lighting products in their businesses during the last six months.

Almost two-thirds of the respondents (63%) said that they believed that LED lighting would be accounting for 50% of their sales and installations by 2009.

The respondents expect the LED lighting market to grow within a variety of application areas, with  the highest being:

  • Street and parking at 20%,
  • Indoor residential at 17%,
  • Retail and display at 17% and
  • Office at 15%

Survey respondents represent top decision-makers and lighting manufacturers who attended the 2007 Hong Kong International Lighting Fair, which is the largest lighting show in Asia and the second-largest in the world. Nearly one-half of the survey respondents were from outside Asia, reflecting the survey’s global reach.

“The survey results present us with a clear and positive picture of LED lighting growth patterns and expectations from leaders in fixture design and manufacturing. “The survey also shows an increasing demand for high-quality, energy-efficient LED lighting,” says Cree director of corporate marketing Greg Merritt.

SciWorks has new exhibit space focusing on the cranks, levers and lasers that are behind the basic science of physics.

In the new PhysicsWorks, displays are grouped by concept into mechanics, light and color, electricity, motion and perception.

The beginning of the exhibit starts with simple displays of levers, gears and pulleys, then moves on to flashier kiosks for electricity and lasers.  Sanford explains, "Not everybody is going to be a scientist, but everybody is going to have to deal with it at some point."

They include a room that captures a photo of your shadow on photosensitive material with an LED flashing light and a game that shows off the focused intensity of lasers.


There are also displays that are more like low-impact rides, such as a kid-size gyroscope, where you sit on a bicycle seat, and holding a spinning wheel by its axle, you turn around. That's the same concept used in the space and air industry to keep shuttles and planes straight, Sanford said.

According to the Federal Highway Administration, in 2000 there were 106,000 crashes from running RED LIGHTS, with 89,000 injuries and 1,036 deaths.

Blue lights above traffic signals  are called "tattletale lights" or "red light confirmation lights." Whenever the traffic signal is red, the blue light is on.

Police previously had to testify that a vehicle was in an intersection when it ran a red light.

Now, officers only have to see the blue light to know the vehicle ran the red signal.

Florida Department of Transportation officials are paying for the lights at intersections on state roads in nine Central Florida counties, reported a representative from the Florida Department of Transportation.

Originally, the DOT put up small white lights at a cost of about $100 each. The DOT is switching to less-expensive blue lights, which are LED (light emitting diodes) that run cooler and need less maintenance.

Running a red light in Florida can bring a fine of $188.50.

Violators also face adding three or four points to their driving record, unless they complete a state-approved driver-safety course.

LED Christmas Lights Save Cities on Holiday Displays

In two recent articles the Daily News reported that the city of Fairbanks, Alaska spent over $880,000 dollars on electricity each year.

HolidayLEDs.com an online retailer specializing in LED Christmas lights and LED decorative lighting is offering to donate energy-efficient LED Christmas lights to the City of Fairbanks to help the city in its efforts to reduce its energy consumption.

News Image

I read an article in the Fairbanks Daily News-Miner about the Cities' efforts to reduce its energy consumption and decided we would offer to help
"I read an article in the Fairbanks Daily News-Miner about the Cities' efforts to reduce its energy consumption and decided we would offer to help," said Philip C. Curtis, President of HolidayLEDs.com.


Fairbanks city engineer, Mike Schmetzer, and his energy task force were reported to have set out to figure out how the city could reduce its energy costs. Some of the proposed solutions of the task force including turning off non-critical streets lights and eliminating Christmas light displays.

"Its commendable that the City of Fairbanks is taking a serious look at its energy consumption--we should all be doing this--but Christmas lighting displays are such an important part of the Christmas celebration it would be a shame if the residents of Fairbanks had to eliminate this tradition," Curtis added.

LED Christmas lights are 80-99% more efficient than standard incandescent lights and substantially reduce the cost of operating a holiday display.

"If Fairbanks replaced its incandescent lights with LED Christmas lights the amount of power consumed would be de minimus and we'd like to help the City make the switch by offering to donate four cases of lights to the City," Curtis explained.

Curtis' company shipped a substantial number of LED Christmas lights to the State of Alaska in 2007. "The residents of Alaska have been good customers to us and we are glad that this opportunity arose to help the citizens of Fairbanks," Curtis concluded.

LED Indicators and signs

LEDs are rapidly rippling across the transportation and vehicle applciations because of their long life, energy efficiency, standalone solar power capability...and brightness.  Here are some recent trends in LED applications:

LED Indicators and signs

Status indicators on a variety of equipment are used which include traffic lights and signals, Exit signs, Railroad crossing signals, Continuity indicators and Elevator push-button Lighting .

Thin, lightweight message displays at airports and railway stations, and as destination displays for trains, buses, trams, and ferries.

Red or yellow LEDs are used in indicator and alphanumeric displays in environments where night vision must be retained: aircraft cockpits, submarine and ship bridges, astronomy observatories, and in the field, e.g. night time animal watching and military field use.

Red, yellow, green, and blue LEDs can be used for model railroading applications

In dot matrix arrangements for displaying messages.

Because of their long life and fast switching times, LEDs have been used for automotive high-mounted brake lights and truck and bus brake lights and turn signals for some time, but many high-end vehicles are now starting to use LEDs for their entire rear light clusters.

Besides the gain in reliability, this has styling advantages because LEDs are capable of forming much thinner lights than incandescent lamps with parabolic reflectors.

The significant improvement in the time taken to light up (perhaps 0.5s faster than an incandescent bulb) improves safety by giving drivers more time to react. It has been reported that at normal highway speeds this equals one car length increased reaction time for the car behind. White LED headlamps are beginning to make an appearance.

As a medium quality voltage reference in electronic circuits. The forward voltage drop (e.g., about 1.7 V for a normal red LED) can be used instead of a Zener Diode low-voltage regulators. Although LED forward voltage is much more current-dependent than a good Zener, Zener diodes are not available below voltages of about 3 V.

LED Christmas Lights Save Money in Three Ways

LED-based Christmas lights have been available since 2002, but are only now beginning to gain in popularity and acceptance due to their higher initial purchase cost when compared to similar incandescent-based Christmas lights.

For example, as of 2006, a set of 50 incandescent lights might cost US$2, while a similar set of 50 LED lights might cost US$10.  The purchase cost can be even higher for single-color sets of LED lights with rare or recently-introduced colors, such as purple, pink or white.

Savings with LED Christmas Lights

Regardless of the higher initial purchase price, the total cost of ownership for LED Christmas lights would eventually be lower than the Total Cost Outlay for similar incandescent Christmas lights since the LED requires much less power to output the same amount of light as a similar incandescent bulb.

More to the point, LEDs have practically unlimited life and are hard-wired rather than using unreliable sockets as do replaceable bulbs. So a set of LED lights can be expected to outlive many incandescent sets, and without any maintenance.

The Ministry of New and Renewable Energy in India cites the following applications of LEDs:

Light emitting diodes (LED) has number of applications. They include devices, medical appliances, indicators and signs, emergency vehicles, flash lights etc.

Devices, medical applications, clothing, toys

• Remote controls, such as for TVs and VCRs, often use infrared LEDs.

• Glowlights, as a more expensive but longer lasting and reusable alternative to Glowsticks.

• Movement sensors, for example in optical computer mice

• The Nintendo Wii's sensor bar uses infrared LEDs.

In optical fiber and Free Space Optics communications.

Toys and recreational sporting goods, such as the Flashflight

Lumalive, a photonic textile

In pulse oximeters for measuring oxygen saturation

LED phototherapy for acne using blue or red LEDs has been proven to significantly reduce acne over a three-month period.

Some flatbed scanners use an array of red, green, and blue LEDs rather than the typical cold-cathode fluorescent lamp as the light source. Having independent control of three illuminated colors allows the scanner to calibrate itself for more accurate color balance, and there is no need for warm-up.

Computers, for hard drive activity and power on. Some custom computers feature LED accent lighting to draw attention to a given component. Many computer manufacturers use LEDs to tell the user its current state. One example would be the Mac, which tells its user when it is asleep by fading the LED activity lights in and out, in and out.

Sterilization of water and other substances using UV light.

D.Light, a startup officially announced its products in June 2008.

The company is in the process of moving its offices to Shenzhen, China, from Mountain View, Calif., to manufacture three LED and solar-based lighting products that cost just $10 to $30 and are meant to replace kerosene lanterns.

The Nova will sell for approximately $12 to $25 and one hour of solar charge can provide one hour of LED light on the medium setting.
 
In many regions of India and Africa that are not connected to the electric power grid, kerosene lanterns provide much of the lighting. But kerosene lanterns can be unsafe and cause respiratory problems; they’re also generally pretty dim and are a contributor to greenhouse gas emissions.

D.Light President Ned Tozun tells us that, while no one would argue replacing kerosene lanterns is a bad idea, technologies such as LEDs and solar panels have just started to become cost-effective replacements.

D.Light was founded by Tozun and his business partners at Stanford with  backing from Draper Fisher Jurvetson, Garage Technology Ventures, Mahindra & Mahindra, Nexus India Capital, Acumen Fund, Gray Matters Capital and Michael Marks (the Chairman of Flextronics). D.Light is working with Seoul Semiconductor for its LEDs and plans to produce in “the millions of units” and strongly focused on getting its goods to the developing world first.
