Last night, thousands of walkers and hundreds of runners in Edinburgh kicked off the Courtesy of NVA.org.uk

A bunch of research went in to creating this light up gear to meet the NVA’s head designer James Johnson’s following standards:

For the runners, the design team wanted something dramatic, so they ended up going with concentrated point source LEDs, which looked great both close and at a distance. The LEDs allowed them to mix color and adjust intensity of the lights remotely. The runners themselves had to be in tip-top shape, able to run 10 miles at a 9-10 minute pace in all kinds of weather. Therefore, as to not hinder them in their physical feat, the design team fashioned a webbing suit out of the LEDs, complete with a radio and battery pack. Check them out:

The only shortcoming of these suits was that they couldn’t be powered by the runner’s motion. After attempting to harvest energy via knee braces, they determined any impediment to the runner’s motion dramatically affects his or her performance.

For the walkers, Johnson and his team wanted to build something subtler, to provide adequate safety lighting, but not to distract from the viewing experience. They decided to go with staffs/walking sticks illuminated by a combination of electroluminescent tape, fiber optic fabric, and diffused and non-diffused LEDs. Each staff housed a micro-computer that would synch up the flashing patterns with the Orchestra’s score, with changes triggered by movement and altitude. And here they are:

The research team was able to use motion to generate power in this instance, since walking is a more leisurely, steadier movement. To harness the power of movement, two LEDs, two high power Neodymium magnets, and a copper coil go in the top of the staff, then as the walker strides along, striking the stick against the ground, one of the magnets oscillates through the coil, creating a small electrical current. One LED lights up when the magnet travels down, and the other when the magnet travels up, producing a twinkly effect.

The runners also received a smaller version of this staff in the form of a baton.

Early in the month, American Airlines Flight 1420 crashed near Little Rock, AK. This crash, along with a few others that took place soon before and after, inspired research into the deleterious effects of sleep deprivation on pilot safety.

In June 1999, Stephen King got hit by a car and was flung 14 feet while walking on the shoulder of a road in Maine. What’s the name of that Stephen King book about the car? Oh yeah, Christine. Any connection? You never know. But I’m sure King was thankful Kathy Bates didn’t find him after the accident.

7) The Weird Looking Predecessor of the MacBook Is Born

That mildly annoying yet overall charming goofball Austin Powers (Mike Myers’s colorful character) graced the cover of Rolling Stone in June 1999, exuberantly celebrating the sequel to the original Austin Powers blockbuster smash hit. Smashing, baby!

9) Adam Sandler Tones It Down a Little

The universe’s hippest couple, who, of course played in a rock band together, hit the popular scene with their debut album in June 1999. Then, they became insanely famous. And then, thirteen thousand two-piece rock bands, featuring only guitar and drums, were born. I think now, 15 years later, we are finally beginning to see the decline in that questionable trend. Bass matters, people.

Venus and Serena Williams, two twin females from a socioeconomically disadvantaged place, won the Grand Slam female doubles event for the first time. They were the second sister team to win a Grand Slam event since 1890. This is the kind of thing that just makes you smile. These are some of the best ever to play the sport.

Saving on energy costs and outfitting your home or office environment with new lamps and light fixtures should be at the top of your home improvement project list.  Not only do new light sources deliver a superb quality of light, they are the key components in decorative and energy-efficient lighting design.

It is an exciting time in the lighting industry.  New products are being developed every day, and LED (light emitting diode) and SSL (solid-state lighting)*  lamps and light fixtures are at the core of future illumination.

What’s more, the integration of LEDs into building and electronic communication systems is bringing everything together and enabling total control with the ease of a smart phone!

Here are some guidelines to help you answer those questions and invest wisely toward one of the greatest home improvement projects of the decade:

WHAT YOUR LIGHTING DESIGN CAN AND SHOULD DO FOR YOU…

In addition to providing optimum levels of brightness, good lighting design must also…

•Eliminate glare

•Increase comfort

•Provide continuity

•Deliver good color rendering

•Allow for adjustability

•Instantaneously make you ”feel good” with an inviting luminous appeal

Because LED lamps require so little energy to provide a great deal of illumination, the energy consumed by the bulb will not be your main concern; your main concern will be getting the desired level of brightness and light appearance.

*NOTE:  LEDs, also referred to as SSL, provide the most energy-efficient and durable illumination because they are composed of “solid state” semiconductor light emitting diodes.

1.    Familiarize yourself with labels on new bulb cartons.

Brightness (in lumens)

Estimated Yearly Cost (depends on rates and use, $)

Lamp Life (based on 3 hrs/day use, rated in years)

Light Appearance (CCT)  (warm-cool, rated in degrees Kelvin (K))

Energy Used (in watts)

Color Rendering (CRI) (measured on a scale of 0-100)

BRIGHTNESS

Brightness levels are measured in lumens to give the amount of total light created by the light source.  Beyond the lumen count, “useable” light and brightness levels are also affected by fixture housings, lenses, filters and shades.  There are clear standards set to measure the lumen output of each LED chip.  ↓

LIGHT APPEARANCE  

Light appearance or correlated color temperature (CCT) helps determine the quality of illumination.  Designated on the Kelvin (K) scale, CCT for decorative interior spaces should be in the warm white (2700-3000K) range.  Sometimes lighting in the neutral white (3500-4000K) is preferred for certain areas, such as bathrooms and kitchens.

LAMP LIFE AND THE LED

Lamp life refers to how long a light source will last once it is installed and used on a daily basis in a typical application. Lamp life ratings, based on estimates from testing,  convey the time that half the bulbs in a sampling have burnt out or dimmed below fifty percent.

COLOR RENDERING AND THE LED

The color rendering index (CRI) measures the ability of a light source to bring out the true colors in décor, objects and surfaces.  Based on a scale of zero (no color rendering) to 100 (perfect color rendering),  a minimum of 80 CRI is acceptable for interior lighting applications.  A CRI of 90+ is even better.

However, because the standard CRI measurement does not always yield true results for some LED light sources, a new standard measure of color quality is in the works:  The Color Quality Scale (CQS) may soon replace CRI for a truer account of color rendering provided by the LED light source.-www.ledlightingexplained.com, Philips Solid-State Lighting, 2010

2.    Match light fixture to light source to ensure peak performance.

LEDs small size, low-temperature emissions, and focused uni-directional beam patterns make them perfect light sources for undercabinet lighting, track lighting and pendant fixtures.

LED general and flood lighting replacement bulbs are composed of clusters of diodes to provide broader beams of light.  General service LED bulbs that are multi-directional with 360-degree angle capacity are doing an excellent job of replicating the desired illumination of old incandescent bulbs. These LED  lamps include A19, PAR, BR and candelabra light sources that are providing more light with the added benefit of tremendous energy-saving, maintenance-free illumination.

Due to their long life and durability, LEDs are excellent in hard to reach places like foyer, attic and cathedral ceiling fixtures.

*Check for compatibility with all new light sources to make sure lamps, light fixtures, dimmers and automated controls are a suitable match.

3.    Compare “apples to apples”; diodes to diodes to ensure top quality.

 Many factors contribute to the quality of the LED light bulb.   Advancements in diode technology and mass production of LED light sources are bringing costs down to make these bulbs more affordable.  However, be wary of “cheaper” LED light sources.

•COB (chip on board), the diode itself is composed of a chip that largely determines  the quality of the bulb.

Prior to being marketed in appliances, fixtures or light bulbs, LEDs are sorted into bins according to their light output (lumen output) and color temperature.  Due to the process of “binning,” LED chips vary in their quality—especially in relation to their lumen output and color, so it is important to purchase LED light bulbs and LED light fixtures from a reputable dealer.

LEDs chosen from bins with higher lumen output are of better quality.  Color temperature is determined by matching up each LED according to a chromatic line grid for a specific color temperature.   LEDs chosen from larger bins contain more color variation , so they deliver an inferior quality of light.

•LPW (lumen per watt), this measurement helps to determine energy-efficiency and efficacy

•IC (integrated circuit) drivers, the quality of the LED lamp is also dependent on the type of driver installed.  LED bulbs contain “drivers” that can fail just like the ballast of a CFL (compact fluorescent). Better driver components make for a higher quality LED light source.

ENERGY STAR-ratings ensure that the LED has met stringent testing procedures.  ENERGY STAR-rated lamps clearly identify characteristics on LED light sources to guarantee that they consistently and reliably meet the desired brightness (lumens), energy-efficiency (lumens per watt), color temperature (CCT), color rendering (CRI), and dimmability requirements.

New ENERGY STAR Regulations include:

•Consistency Control:  More standardized testing methods to improve consistency.

•Dimmability Ratings:  A lamp is either dimmable or not dimmable.  If a lamp claims to be dimmable, testing is required and it must dim down to at least 20 percent.  If it is not dimmable, it must say so on the package.

•Greater Energy Conservation:  Efficiency requirements have increased for specific lamp wattages and types.

NOTE:  The Environmental Protection Agency (EPA), along with ENERGY STAR offers rebate programs as an added incentive to help you spring into action and upgrade with LED.  Check out rebate programs in your area or contact an American Lighting Association (ALA)-affiliated showroom for more details.
