Energy Star LED Insight on Leadership for Energy Efficiency

Energy Star LED Bulbs and DLC Listed LEDs are available from many manufacturing companies like Independence LED Lighting. However, Energy Star LED Lights did not include a category for LED Tubes. Now, the DesignLights Consortium (DLC) plays a key role in defining standards for utility companies to use as a guide in rebate eligibility. Independence LED took a leadership role in creating the demand for an entity that would help the utility companies determine which products were worthy of rebates and was the first to offer a 5 Year Warranty that set the DLC standard. Prior to the Independence LED 5 Year Warranty in 2009, the vast majority of imported LED tubes and lighting products only had warranty coverage from 1 to 3 years. In 2013, Independence LED pushed the par even higher as the first to provide 10 year warranty protection on its Made in America LED Lights.  Since the Energy Star LED Lighting review capability was limited to a much smaller sub-set of Energy Star LED socket bulb technology offerings, the market needed standards for the full range of Commercial and Industrial offerings.


May 7, 2012: An Open Letter to the Lighting Industry

Charlie Szoradi is the Chairman and CEO of Independence LED, a Pennsylvania-based commercial lighting company that has developed an LED replacement for fluorescent tubes. The Company has recently moved its manufacturing from China to America.

The leadership of the Federal government’s ENERGY STAR programs must work with the Lighting Industry to further the adoption of American-Made advanced lighting technologies. Currently, ENERGY STAR is a barrier to the adoption of key technologies, such as new LED fluorescent tube replacements, because there is no available listing criteria. LED tube technologies have been left out even though the most recent ones provide reliable, sustainable, low cost energy efficiency retrofits for commercial and industrial customers. With ENERGY STAR certification, American companies can more easily implement lighting efficiency retrofits that will create jobs, lower operating costs, limit disposal and overall environmental impact, and support a more robust and efficient American economy.

LOOK UP. Fluorescent tubes are most likely in your office ceiling. The tubes have dominated commercial lighting since the 1950s1, and lighting now accounts for 30%-35% of all commercial electricity use, according to the Electric Power Research Institute. (EPRI) 2.  Unfortunately, fluorescent lighting is inefficient relative to LEDs, less durable, more maintenance intensive, and creates serious environmental disposal issues given the toxic mercury vapor. New cost-effective LED linear “tube” technologies cut lighting operating costs by more than half and save tens of billions of dollars for U.S. companies. After many years of research effort, ENERGY STAR still has not even published listing criteria for these important new technologies. They simply need to test the most recent linear LED products with dramatically more robust thermal management than the predecessors.

The fact that LED Tubes are currently not on the ENERGY STAR list, even for American manufacturers, seems to be a contradiction to National policy, given that President Obama has spoken so passionately about energy efficiency and clean tech jobs. Fortunately, the fix is quick – ENERGY STAR’s leadership could rapidly implement new listing criteria and facilitate technology adoption without any legislative friction.

ENERGY STAR remains the primary gate keeper to energy efficiency rebates, since U.S. Utility Companies often rely on the label to determine incentive “Rebate” qualifications. ENERGY STAR branding also serves as an objective “Seal of Approval” that complements the financial rebate advantage. Without ENERGY STAR, this efficient and sustainable technology is significantly handicapped. The result is that massive energy and environmental waste continues to burden government facilities and business that unnecessarily pay higher monthly operating costs for electricity.

Looking at the Public Sector, the calculation on the potential savings by replacing fluorescent tubes with LEDs is eye opening.  With over 1.25 million buildings, 3.87 billion sq. ft. and 120 million tubes in Federal government property portfolio, the Annual Savings with LEDs would be over $600 million3. According to the U.S. Department of Energy (DOE), the national fluorescent tube count is in excess of 2.3 billion tubes4. Americans throw away over 600 Million fluorescent tubes each year. At this scale, new efficient LED technologies can achieve significant efficiency and environmental benefits.

With a clear path to an ENERGY STAR listing for LED Tube products, America can thrive:

  • The Private Sector Lighting Retrofit market for Commercial and Industrial facilities grows even if the government property retrofits lag behind.
  • Equipment lease and financing companies step up to support the energy retrofits for the LED tubes that meet the ENERGY STAR criteria.
  • A significant portion of the 70 billion sq. ft. (US Census) of Commercial and Industrial properties change from fluorescent to LEDs and create domestic job opportunities for auditing and installations.
  • America moves closer to Energy Independence and Energy Security.

So why are we where we are today?

Several years ago, the DOE conducted studies that determined that certain early LED tubes, primarily imported from China, did not meet minimum performance criteria. Over the last two years, there have been dramatic improvements in technology, durability, thermal management, and overall quality of light for the latest imported and domestic products. But the industry does not have a clear path forward, since ENERGY STAR has not released any performance criteria for a listing. ENERGY STAR works in concert with the DOE, and the DOE is influenced by third party “experts” some of whom may work for lighting companies that make…fluorescent tubes. The fluorescent tube manufacturers are major brands and multi-nationals that continue to have a powerful influence to protect their billions of fluorescent tube sales worldwide.

The Lighting Industry, as a whole, needs to take a more proactive approach with ENERGY STAR, the DOE, the EPA and other government and regulatory bodies to develop an efficient and rapid certification process to study and set approval standards for new lighting technologies to earn ENERGY STAR listings. New LED tube technologies would be a great first step. Displacing the status quo is always a difficult process, but enabling innovation and progress in lighting technology will yield substantial rewards across the country.

#3: The Waste / Savings Potential

Formula: (Savings per Tube per Year with LEDs ) X (# of Federal government Tubes) = Annual Savings with LEDs across the Federal government real estate footprint.

(Note: The Savings is almost three times higher in 24/7 areas like Exit Stairs, and it is also significantly higher in States like California and across New England where the cost per kWh is higher than the U.S. average. Given the massive footprint of Department of Defense (DOD) real estate overseas, the savings is dramatic given that the cost per kWh in many European and other countries is more than twice the U.S. Average.)

Support Info: The Watts / sq. ft. for offices comes from the ASHRAE benchmarks:

The Federal Real Property Profile (FRPP) is the single comprehensive inventory system that contains data on all federal real property assets within and outside the United States, including improvements on federal land.

The government’s portfolio of building assets totals approximately 3.87 billion sq. ft of space. In all, the government had a total of 1.25 million building, land, and structure assets with a total replacement value of $1.53 trillion.

Of the total Federal properties more than half is the Department of Defense, “DoD occupies a reported 300,658 buildings throughout the world, valued at over $575 billion comprising over 2.2 billion sq. ft.”  Source: Page #12: Military Report:
