The U.S. Department of Energy (DOE) has released an exploratory CALiPER study on the problems and benefits likely to be encountered as LED products intended to replace linear fluorescent lamps become increasingly popular. Eighteen lighting designers and facility engineers compared 24 identical pairs of troffers in a simulated office space. Three of those pairs involved fluorescent benchmark troffers, and the rest were LED products.

The products were evaluated for photometric distribution, uniformity of light on the task surface, and suitability of the light output for the task, as well as flicker, dimming performance, color quality, power quality, safety and certification issues, ease of installation, energy efficiency and life-cycle cost.

The conclusions included:

* While lighting quality is of some concern with the LED products, it’s no more so than with the linear fluorescent lamps they’re intended to replace.
* LED dedicated troffers can compete with (and beat) fluorescents in terms of efficacy.
* LED replacement tubes and non-tube retrofit kits are as efficacious as their fluorescent counterparts, though there are concerns about color consistency, glare, dimming, flicker, installation issues, and code approval.
* For this reason, it’s advisable to mock up and visually evaluate LED retrofit products before ordering them for large installations.

Out of 125 submissions from New York City lighting design students, “Atherisch,” designed by Peter Ossi, a BID industrial design major at Pratt Institute, was awarded the grand prize at the Illuminating Engineering Society New York City Section’s (IESNYC) 13th annual student lighting design competition. Ossi receives a $2,000 cash prize and an all-expense paid trip to Paris to visit Debbas L’Atelier.

“This was an especially challenging year for the students,” says Shaun Fillion, chair of the Student Lighting Competition Committee and lighting project design manager, Osram Sylvania. “Past themes have focused on visual lighting cues, such as shadows or the reflection of light. IllumiNotes encouraged entrants to respond to a completely non-visual form, manifesting in their track of choice from Craig Armstrong’s album Piano Works into a silent visual lighting piece. As a result there was more diversity among the projects, as the challenge was limited only by the imagination of the students.”

Atherisch

Atherisch

Ossi’s Atherisch, which is the German word for “ethereal,” was inspired by a piece in Piano Works called Fugue, a piece that according to Ossi,” is a dance of two spirits that breathe a sanguinary yet ethereal feeling of playful reverie.” The concept for his design stemmed from the idea of refracting light through the action of breathing. His first model reflector was operated with his own lungs, breathing through a tube attached to an airtight drum with a diagram of reflective Mylar on one side. In the final model he replaced his lungs with a reciprocating piston driven by a 1 rpm motor and a positive return cam mechanism. The entire mechanical and lighting portion was then encased within a white amorphic, amoeba-like casing made of foam insulation coated with joint compound and painted.

Spectrum

Spectrum

The second prize of $1,000 was awarded to Eunyong Park, a BID Student at Pratt Institute for her installation Spectrum. Different heights of straws make a variety of rhythmical light movements like the notes played in Craig Armstong’s piece Delay. The viewer receives the light at different eye levels and angles that deliver high and low, fast and slow, and loud and quiet sounds of the piece.

A Suspended Storm

A Suspended Storm

Sophia Arrendondo, MP Lighting Design, NYSID was awarded a third prize of $500 for Model for A Suspended Storm. Inspired by Craig Armstrong’s “Weather Storm,” the idea of this installation was to create an image of a storm suspended in time.

“Light and sound are both totally immersive forms of experience, capable of instantly establishing a mood, and there’s a long history of designers and composers seeking inspiration in each other’s work,” says Joseph Clarke, an architectural historian, critic, and PhD candidate at Yale University (co-convener The Sound of Architecture symposium this past fall at Yale), who delivered the event’s keynote address and served on the competition jury. “This year’s theme was also a very open-ended problem, challenging students to stretch their creative boundaries and eliciting an amazing variety of submissions.”

Honorable Mentions includfed Jennifer Wei – BFA Product Design, Parsons The New School for Design; Karina Oumov – BID Industrial Design, Pratt Institute; Carla Ramírez – BID Industrial Design, Pratt Institute; and Marland Backus – BID Industrial Design, Pratt Institute.

The jury included Clarke; Mike Barr, senior account supervisor, Lutron; Juan Pablo Lira, senior designer, Focus Lighting; and Christopher Lubeck, NAFTA head and specification sales engineering and utility relations, Osram Sylvania.

NEMA’s shipment indexes for T5 and T8 liner fluorescent lamps increased 2.1 and 15.1 percent in the fourth quarter of 2012 to reach 156.8 and 103.1, respectively. However, the quarterly gains were not able to offset decreases earlier in 2012. The index for T5 lamps posted an annual reading of 159, a decline of 10.7 percent from 2011. T8 lamps declined 14 percent during the year to reach an index value of 99 for 2012. Shipments of T12 lamps showed the largest annual slide, dipping by 18.6 percent to 50 –half the level of 2006. Similarly, the index for T12 lamps reached a new record low of 36.6, a decline of 1.1 percent during Q4.

T12 shipments lost 2 percentage points during Q4 ending at 16.9 percent. On an annual basis, T12 shipments garnered a share of 22.4 percent, buoyed by stronger performance during the first half of the year. Shares of T5 and T8 lamps increased slightly on an annual basis by 0.5 and 0.6 points to 10.0 and 67.6, respectively.

Philips LED Technology Helps Shine Light on Bay Bridge as Sustainable Art

The Bay Lights, the new LED lighting system for the Bay Bridge that was developed by Philips Color Kinetics, recently went live. Fulfilling the brainchild of Ben Davis, chairman of Illuminate the Arts (ITA) and the vision of acclaimed artist Leo Villareal, the bridge will glow as a one-of-a-kind lighted sculpture for the next two years. Installed with the support of the California Department of Transportation (Caltrans), the bridge is expected to be viewed by over 50 million people and bring nearly 100 million in revenue to the local San Francisco economy. The new LED lighting system uses 85 percent less energy than traditional lighting technologies, energy that will be offset by dedicated solar panels set up in Davis, CA by CleanPath.

Villareal, creator of The Bay Lights, is a pioneer in the use of LED lights and computer driven imagery using Philips Color Kinetics eW Flex SLX product in 4200 Kelvin correlated color temperature for the Bay Lights project. eW Flex SLX is a versatile strand of individually controllable white light LED nodes. The durable, flexible form factor allows dynamic points of white light to be installed across nearly any interior or exterior surface which made it an ideal choice for The Bay Lights project. Philips Color Kinetics worked with Villareal to create custom spacing between the nodes to accommodate his design. In the end, almost 4.5 miles of product was installed on the bridge, roughly equal to the total length of the Bay Bridge, counting both spans. The lighting will be viewable from San Francisco and points north, but not by drivers crossing the bridge.

Turning the bridge into a monumental light sculpture is a unique application of LED lighting technology that sets the Bay Bridge apart. Villareal networked 25,000 of these LED nodes to create complex algorithms and patterns across the bridge’s western span. These patterns dynamically recombine themselves over the two-year duration of the installation, transforming the bridge into a living piece of art which organizers believe to be the world’s largest LED light sculpture.

Organizers of The Bay Lights have provided all the financial support for the project through private funding, not tax payers. Over the course of the year, it will cost approximately $11,000 in energy to light the piece, which translates into $30 per day or $4.25 per hour.
