Freedonia: U.S. Demand for Lighting Fixtures to Top $25 Billion by 2016

Demand for lighting fixtures in the U.S. will increase 7.5% annually to $25.3 billion in 2016, recovering from the declines of the 2006-2011 period, according to Lighting Fixtures, a new…

Demand for lighting fixtures in the U.S. will increase 7.5% annually to $25.3 billion in 2016, recovering from the declines of the 2006-2011 period, according to Lighting Fixtures, a new industry study by The Freedonia Group.

An expected rebound in building construction activity and improved outlook for motor vehicle production will be important drivers for the lighting fixture market. Demand will also benefit from the greater use of lighting fixtures that are specifically designed for energy-efficient light sources such as LEDs.

Construction applications account for the majority of lighting fixture demand and through 2016 are expected to post the fastest growth of any major market, rising 8.5% annually to $15 billion. The residential market is expected to post the strongest gains in percentage terms, driven by the rebound in housing construction from a low 2011 base.

The large nonresidential market for lighting fixtures will also experience strong growth through 2016, increasing nearly 8% per year. While not as high in percentage terms, the large size of the nonresidential market means that this segment will provide the best overall opportunities, with an additional $3.1 billion in demand in 2016, compared to the 2011 market.

Meanwhile, the non-building lighting fixture market is forecast to grow the slowest of the major construction markets, reflecting the segment’s good performance between 2006 and 2011 in comparison to both the residential and nonresidential segments. The vehicle and machinery market is expected to rise 7.5% annually through 2016, supported by a rebound in motor vehicle production and strength in shipments of aerospace and other transportation equipment (e.g., industrial vehicles, trains, and boats).

Stairwell lighting is typically operated continuously at full output in nonresidential buildings even though these spaces are only intermittently used. In recent years, lighting manufacturers have begun offering a control solution that can reduce energy costs while providing satisfactory levels of illumination for emergency egress. These lighting fixtures automatically adjust light levels based on occupancy.

The 2011 GE Edison Award was presented to Glenn Heinmiller, Paul Zaferiou and Dan Weissman of Lam Partners for lighting the United States Institute of Peace in Washington, DC. A personalized Steuben crystal award for the 29th annual lighting design competition was presented by GE Lighting during LIGHTFAIR. The GE Edison Award competition is open to those lighting professionals who creatively employ significant use of GE light sources (lamps and/or LEDs) in a lighting design project completed during the previous calendar year.

The first permanent home of the United States Institute of Peace is prominently located near the Lincoln Memorial in Washington, D.C. The translucent wing-like roofs that connect the building’s three curving sections presented the most challenging lighting problem: to light the roofs with no visible sources so they glow softly both inside and outside. A pervasive lighting theme, featuring GE T5 fluorescent lamps, is present throughout the building. Light sources are fully concealed or designed to disappear, revealing and animating, but never competing with the architecture.

The roofs are comprised of an outer diffusing glass and an inner white membrane, with structure sandwiched between these two layers. Forward-throw cove fixtures, with GE 54W T5 3000K fluorescent lamps, are mounted in the tops of walls to light the roofs. This single lighting layer simultaneously provides the interior ambient lighting and the exterior surface glow. Above the uppermost windows, necklaces of matching adjustable monopoints with GE 37W Precise IR MR16 halogen lamps and 39W ConstantColor CMH PAR20 lamps provide supplemental downlighting. In-grade ceramic metal halide adjustable fixtures illuminate the roof’s overhang, seamlessly extending the glow outside to the roof’s lowest point.

Perimeter offices are fully daylighted, and the clerestories bring daylight into the corridors. Inexpensive T5 fluorescent strips with GE 21W T5 3000K lamps are integrated continuously into the curving base of the clerestories to indirectly light both the offices and corridors. In addition, each office has a custom T5 pendant with shielding, designed to block views into the fixtures from outside or from within the atria.

A central lighting control system employs occupancy sensing, daylight sensing scheduling, and local preset scene control. The project is LEED Gold certified.

Tivoli, LLC recently announced the publication of a two new AIA Continuing Education courses entitled, “How We See Color” and “How We Use Color.”

The first helps students understand how the human eye detects and identifies color. Upon completion of the course, students will be able to describe how we see and measure color with traditional and LED light sources, as well as gain an understanding of Color Temperatures, CRI, Color Consistency, and Metamerism. The second part presents recommendations and solutions on how to use color in lighting designs to achieve the desired effect.

Both of these one-hour courses, free and suitable for any audience, are accredited at 1 AIA Learning Unit (LU) hour. The on-line courses are available by logging onto hanleywooduniversity.com or AIA.org.

National September 11 Memorial Honored with IALD Award of Excellence

In downtown Manhattan, the National 9/11 Memorial opened on the 10th anniversary of the 2001 tragedy.

“A very powerful installation where light forms a strong contrast to the despair of the dark void,” commented one IALD Awards judge on the lighting design.

After extensive studies and select site visits around Manhattan, the designers were able to dissuade city officials that the initial 5-footcandle requirement for the plaza was excessive. In the finished project, both the horizontal and vertical illuminance is 0.5 footcandles.

For a project fraught with challenges and restrictions, the lighting vocabulary is relatively simple, as only three fixture types light the project.

Custom pole fixtures, aligned with the landscape grid, feature an up-down lighting component with four T8 lamps behind a stack of prismatic refractors. Humane and gentle illumination of the visitors was the principal challenge. Equally important was to provide adequate vertical illumination for the security cameras. The two fountains, set in the original footprint of the towers, are discrete upon entry. Granite pavers and the rhythmic hymn of cascading water lead visitors to the threshold of the south pool.

Collaborating closely with the manufacturer, over 1,500 feet of submersible LED luminaires, driven at 24 volts with an internal water cooling technology, are mounted beneath the waterfall at the base of each pool. The falling water dances in the light, creating a powerful reflection that oscillates between celebration and sorrow.

The International Association of Lighting Designers (IALD), established in 1969, is an international organization supporting a network of 800 lighting design professionals who satisfy its rigorous qualification process. Its members are distinguished by a unique blend of aesthetic and technical expertise, and operate at the highest level of integrity to create a better world through leadership and excellence in lighting design; to cultivate the universal acknowledgement and appreciation of the Power of Light in human life.

Regulation coming in July will put millions of directional lamp sockets for halogen sources up for grabs. Energy standards covering incandescent reflector lamps, first instituted by the Department of Energy (DOE) in 2009, and going into effect starting in July, will eliminate a majority of the least-efficient and lowest-cost options from the market in favor of higher-efficacy alternatives.

That’s the subject of an article I wrote for ARCHITECTURAL LIGHTING, available here.

The article describes the regulations and then explores compliant alternatives, which include today’s most efficient infrared-reflecting halogen as well as LED, ceramic metal halide and compact fluorescent directional lamps.
