Angie’s List Infographic – LEDs

A lot of companies are participating in the new LED light bulb market, also called Solid State Lighting or SSL. These companies can be LED light bulb makers or participate by making some component of the LED light bulb ranging from heat sinks and LED chips to the sapphire growers, polishers and fabricators that make the foundation of the LED, the sapphire chip. All of them have a vested interest in helping consumers understand LED light bulbs and why they are different from CFLs and traditional incandescent light bulbs. We’ve gathered together some resources to help consumers understand their lighting options.

The US Department of Energy is leading the effort to educate consumers about their new lighting options and have enlisted companies that participate in the LED lighting market to help. The DOE has developed some very good resources on their own web site for the industry, http://www1.eere.energy.gov/buildings/ssl/. But they’ve also developed resources for consumers to learn more about their lighting choices. Some sample resources for consumers to learn more about LED lighting include a good FAQ here, http://energy.gov/articles/askenergysaver-led-lights.

The Federal Trade Commission requires a new lighting label, Lighting Facts, on all light bulb packages to help consumers understand what they’re buying. Optical and lighting publication Novus Light Today wrote about these new labeling requirements featuring an infographic from light bulb manufacturer Cree.

Many of these companies as well as consumer groups are producing infographics to help the consumer learn more. Here’s a round-up of links to additional resources for learning more about LEDs.

The information in the Angie’s List infographic is great, except for the pricing. LED light bulbs have gone down quite a bit in price with some at retailers in the US coming in at just under $10 and a few others cost less and are even more affordable when combined with rebates and other special offers.

The NRDC does a great job at comparing LED light bulbs to CFLs and traditional incandescent light bulbs and gives a good explanation at the new light bulb packaging required by the US government.

LED Lighting Adoption – Lessons Learned

Incandescent lighting ruled the world for more than a century, but times have changed as the world looks to energy efficient alternatives to the incandescent bulb. In the 1970s, compact fluorescent light bulbs (CFLs) came along as the new alternative light source. Market penetration for CFL bulbs never rose above 1% of all units in the first 20 years following market introduction.

In the US, the US Department of Energy joined together with retailers and the lighting manufacturers to encourage consumer adoption of energy-efficient lighting including LEDs and CFLs. There has been careful consideration not to repeat the mistakes experienced with CFLs that led to that very slow adoption rate.

We’ve spoken a lot about the EISA phase-out of incandescent bulbs in Clearlysapphire.com. US legislators imposed strict energy efficient guidelines impacting incandescent light bulbs in the Energy Independence and Security Act of 2007. In a rolling phase-out through 2014, manufacturers stopped making 100-W, 75-W, 60-W and 40-W incandescent light bulbs. But that legislation is only part of today’s story.

Before the phase-out legislation, The Energy Policy Act of 2005 established the Next Generation Lighting Initiative, directing the DOE to “support research, development, demonstration, and commercial application activities related to advanced solid‐state lighting technologies based on white light-emitting diodes.” This legislation was an important part in establishing the DOE’s leadership in the adoption of solid state lighting (SSL).

The US Department of Energy reviewed the CFL experience and developed a strategy for leading the industry and supporting their activities for SSL.  The DOE analyzed both CFL adoption and early SSL experiences since they’ve launched to determine a strategy for the initiative. You can find links to the reports below in Further Reading.

Some of the lessons learned were quite reasonable. First, coordination and collaboration between government and industry should take place at a national level. Secondly, they needed to establish standards and product testing for minimum performance and back-up of long-life claims with standard-based projections and/or guarantees.  Thirdly, they needed to introduce new lighting technology in applications where the benefits were clearly established before moving on to others. They also found they needed to respond to the market and resolve problems and issues quickly. Finally, they needed to know and acknowledge technology limitations, determine and address compatibility issues with conventional lighting, deal with technology failures aggressively, and not launch a new product until performance issues were ironed out.

The parties in the initiative analyzed LED technology itself and possible bumps in the road to mitigate for consumers. They knew that consumers would have to get used to new language of LEDs. For example, the different way of communicating light brightness in lumens rather than traditional watts might cause confusion. The DOE worked with manufacturers proactively to communicate the new language of LEDs through the introduction of new package labeling, LED Lighting Facts program. They also established CALiPER program, to test a wide array of new LED lighting products for the public interest using industry-approved metrics. With a myriad of new LED light bulb offerings, consumers can find LED light bulbs that are qualified using 20 standards and procedures by the familiar Energy Star program. These proactive efforts were designed to smooth the transition and advance consumer adoption.

How successful have these government and industry efforts been?

There has been a very big change in the installed base of light bulbs between 2010 and 2012.  This is mainly due to the government mandated light bulb phase-out. According to Navigant Research and the DOE, the installed base of incandescent A-type lamps (traditional light bulb shape) decreased from 65 percent to 55 percent, while CFLs increased from 34 percent in 2010 to 43 percent in 2012.  LED installations in A-type lamps remained at less than 1 percent in 2012.

But taking note of lessons learned, it was interesting to see increased adoption in applications where LEDs have clear benefits — directional lighting such as lighting used in recessed lighting. According to the DOE and Navigant, installations of directional LED lamps went from 0.1 million in 2009 to 11.4 million in 2012, with an estimated 4.6% of all directional sockets in 2012 using LEDs.

Adoption is looking up for other lighting applications. Analysts expect LED-based lighting to grow, and fast. According to research firm IHS, 2014 will be a big year for LED lamps, accounting for 32% of the entire global lamp revenue.

The biggest barrier to consumer adoption in traditional A-type lighting so far is price, but the prices are coming down to more palatable levels for consumers.
