Aelux takes part in Lightfair International 2010

Thursday, June 17th, 2010

Aelux had the opportunity to take part in LIGHTFAIR® International (LFI), the world’s largest annual architectural and commercial lighting trade show and conference, which experienced its most phenomenal West Coast show last month. The 2010 show and conference, which took place in Las Vegas, ended with a record-breaking number of 22,000 registered attendees—increasing attendance by 10% from LFI 2008 in Las Vegas and making it the largest in LFI’s West Coast history.

This year, LFI debuted a new pavilion on the trade show floor, the Building Integration Pavilion, which featured companies with enterprise system technologies used to maximize and create energy efficient buildings and showcased many of these successful projects. In addition, nearly 100 industry experts presented 72 sessions, addressing topics that covered lighting fundamentals, software, applications, controls and solutions, as well as design innovation, sustainability, energy-efficiency, product updates and case studies.

Aelux’s technical team spent several days reviewing the latest new technologies being offered by hundreds of new and established manufacturers. LEDs were the hot product line with dozens of new companies competing for what they billed as the future of lighting.

There is no doubt that within the next 5 to 10 years there will be LED solutions for every lighting environment; but we are just not there yet. LEDs are excellent for decorative and retail applications and even a few very high-end commercial uses. However, for the conventional industrial/commercial/institutional marketplaces, the efficiency delivered by the LEDs when combined with their high cost simply does not provide the high ROIs our customers have come to expect. There is one notable exception. We found some very interesting LED solutions for outdoor/garage lighting, and we are working closely with a couple of potential suppliers to see if we can offer outdoor solutions that will insure both quality and real value.

We were impressed with the developments of a couple notable manufacturers of induction lighting, and see a place in the high bay and outdoor space for this technology now. To be sure, the first cost is still higher than fluorescents, but the benefits of producing the same light output from a single lamp (as opposed to 3,4,6 or 8 lamps for linear T8/T5HO fluorescents) has caught the attention of several of our clients. Coupled with up to 100,000-hour lamp life, the ROI on these systems can rival fluorescents when accounting for total cost of ownership.

In the meantime, the fluorescent manufactures have not been idle. There are new higher efficiency lower wattage T-8s and T-5s that will make our fluorescent retrofits even more efficient and produce even higher returns.

It is without a doubt that “LIGHTFAIR International continues to evolve as the premier event for the lighting industry and as the world’s largest architectural and commercial lighting trade show and conference,” says Rochelle Burt, managing director of LIGHTFAIR International.

Aelux understands that the lighting industry is more dynamic than ever, and you can be certain that we will always be in the forefront of bringing our customers the best values possible.

DOE’s 2012 standards for general-service fluorescent lamps

Wednesday, December 2nd, 2009

On July 14, 2012 products with the lowest efficiency and lowest cost will be eliminated by the Department of Energy.  Products failing to achieve the new standards will be prohibited from manufacture in the United States. Here is a summary of the new lamp standards:

Lamp Correlated color temperature Energy conservation standard (lumens/W)
4-ft. (T8-T12) medium bi-pin >25W <4500K 89
>4500K and <7,000K 88
2-ft. (T8-T12) U-shaped >25W <4500K 84
>4500K and <7,000K 81
8-ft. (T8-T12) Slimline >52W <4500K 97
>4500K and <7,000K 93
8-ft. (T8-T12) HO <4500K 92
>4500K and <7,000K 88
4-ft. (T5) miniature bi-pin standard output >26W <4500K 86
>4500K and <7,000K 81
4-ft. (T5) miniature bi-pin HO >49W <4500K 76
>4500K and <7,000K 72

These lamp types will no longer be manufactured:

• Most 4-ft. linear full-wattage and energy-saving T12 lamps
• All 2-ft. full-wattage and energy-saving U-shaped T12 lamps
• All 75W F96T12 and 110W F96T12HO lamps
• Most 60W F96T12/ES and 95W F96T12/ES/HO lamps
• All 4-ft. T8 basic-grade 700/SP series lamps rated at 2,800 lumens
• Some 8-ft. T8 Slimline single-pin 700/SP series and 8-ft. T8 HO RDC-base lamps

“Will America lose the clean-energy race?”

Monday, August 3rd, 2009

Teryn Norris and Jesse Jenkins are Project Director and Director of Energy & Climate Policy at the Breakthrough Institute. They are co-authors of the National Energy Education Act proposal and warn that America faces a new global competition that will have far greater implications for the future of our nation and the world: the clean energy race.

While Congress debates climate and energy legislation, Asian challengers are moving rapidly to win the clean energy race. China alone is reportedly investing $440-660 billion in its clean energy industries over 10 years. South Korea is investing a full two percent of its GDP in a “Green New Deal” to expand their share in cleantech markets. And Japan is redoubling direct incentives for solar power, aiming for a 20-fold expansion in installed solar energy by 2020.

In contrast, the United States would invest only about $1.2 billion annually in energy research and development and roughly $10 billion in the clean energy sector as a whole under the Waxman-Markey bill — less than 0.1 percent of U.S. GDP. This funding level is so low that a group of 34 Nobel Laureates recently submitted a letter to President Obama decrying the lack of investment and calling on the president to uphold his promise to invest $15 billion annually in clean energy R&D — fifteen times the current level in Waxman-Markey.

The U.S. is not only investing far less in our clean energy industries than Asian nations, but also falling behind in energy science and technology education. Only 15 percent of undergraduate degrees earned in the U.S. each year are in science, technology, math, and engineering (STEM) areas compared to 50 percent in China, according to the National Science Foundation — all at a time when nearly half of our current energy workforce is expected to retire over the next decade.

This spring, the Obama administration proposed an initiative designed to bridge this dangerous energy education gap by inspiring and educating thousands of young Americans to pursue careers in clean energy. The program, called RE-ENERGYSE (REgaining our ENERGY Science and Engineering Edge), would fund new undergraduate and graduate energy curriculum and train up to 8,500 highly educated young scientists and engineers in the clean energy field by 2015 alone. Technical training and K-12 funding would support hundreds of programs nationwide to train thousands more technically skilled clean energy workers.

As President Obama announced in April, “The nation that leads the world in 21st century clean energy will be the nation that leads in the 21st century global economy… [RE-ENERGYSE] will prepare a generation of Americans to meet this generational challenge.”

Unfortunately, the U.S. Senate and House recently rejected the Obama administration’s energy education proposal, with the Senate cutting the program from $115 million to $0 and the House appropriating only $7 million.

If the U.S. had responded to the Soviet launch of Sputnik the way today’s Congress is responding to the Asian energy challenge, America would not only have lost the space race, we would have been left behind in the technologies and industries that fueled a half-century of economic progress.
Indeed, the U.S. simply could not have won the space race without major federal investments in targeted education programs. Spurred on by the Soviet launch of Sputnik, Congress passed the National Defense Education Act in 1958, committing billions of dollars to equip a generation to confront the Soviet challenge. These investments developed the human capital necessary to put a man on the moon and invent the technologies that catapulted our world into the Information Age, from microchips and telecommunications to personal computing and the Internet.

Last week, a group of over 100 universities, student groups, and professional associations submitted a letter to each member of the Senate urging full support of RE-ENERGYSE. “America is in danger of losing its global competitiveness and the clean energy race without substantial new investments in science, technology, math, and engineering education,” they wrote. “RE-ENERGYSE… will train America’s future energy workforce, accelerate our transition to a prosperous clean energy economy, and ensure that we lead the world’s burgeoning clean technology industries.”

To win today’s clean-energy race, the United States must respond with the same vigorous commitment to education and innovation that won the space race four decades ago. Congress should begin by strengthening RE-ENERGYSE to the full $115 million requested and pass energy legislation that invests $30 billion to $50 billion annually in low-carbon energy, including the $15 billion in energy R&D called for by our nation’s top scientists.

If America does not take immediate action to bridge its energy education gap — and if we fail to make substantially larger investments in our own clean energy economy — we will effectively cede the clean energy race to Asia. Forty years from today, we may still find the burgeoning clean energy economy promised by President Obama and Democratic leaders. It will simply be headquartered in China.

Dotting Your CRI’s and Crossing Your CCT’s

Monday, June 15th, 2009

LIGHTING FUNDAMENTAL:
Different tasks require different lighting.
The wrong fixtures will cost you in productivity.

Color Rendering Index (CRI) is an important consideration for task lighting. CRI refers to the ability of a light source to render colors reflected to a standard, such as daylight. Daylight is given a CRI of 100. Higher numbers indicate a light source that will reflect more colors of an object compared to how it would be reflected in daylight. For instance, new T8 lamps offer a CRI of 85 — more colors and better lighting than standard fluorescent and metal halide lamps. 33-60% energy savings coupled with available rebate and grant programs are prompting more and more companies to retrofit with T8 lamps.

Correlated Color Temperature (CCT) is also important in choosing lighting for the correct task. CCT is measured in Kelvin (K). Lower color temperatures (below 3200K) are usually considered warm, while those above 4,000K are considered cool. Daylight is 6500K. 5000K, a popular fluorescent CCT for a cool light, is gaining more prominence in the High Intensity Fluorescent segment for industrial lighting. 5000K is also being preferred in certain office applications. Employees should be considered when choosing to switch, and it is often a good idea to have a test area before switching to a different CCT.
