2 Section 1 EXECUTIVE SUMMARY 1.1 Introduction Since the days of Thomas Edison, lighting has been visualized as an incandescent bulb with a hot glowing filament. Today, we commonly envision the compact fluorescent lamp (CFL) as the next step toward more efficient lighting. However, fluorescent technology is not new at all. While Edison invented the incandescent lamp in 1879, the precursor to fluorescent lamps was theorized more than 20 years earlier in Moreover, the first mercury vapor lamp was patented in Fluorescent lamps and all light sources in hollow glass enclosures represent early 20 th century technologies. It could be argued that general illumination white light-emitting diodes (LEDs) are the first true advancement in lighting since its invention more than 130 years ago. Pike Research proposes that, with the start of white LED production in the late 1990s, we are approaching the end of the first chapter in lighting. The transition to solid-state lighting (SSL) may be occurring faster than many predict. If we look at the modern era of technology, experts have accurately predicted the early adoption of new technologies. Yet, the rate of mass adoption has repeatedly been greatly underestimated. The following examples are just a few of the well-known revolutionary market transformations: The transistor was introduced in 1954 and displaced the vacuum tube by the early 1970s 16-year transition The flat-panel display introduced in 1995 replaced the cathode ray tube (CRT) by year transition The DVD introduced in 1997 replaced VHS tapes by year transition The digital camera introduced in 1997 completely replaced the film camera by year transition The smartphone introduced in 2002 displaced the plain cell phone by year transition General illumination white LED introduced in 2007 will replace fluorescent by? years Although this is not to suggest that LEDs will displace all other lamps in the next few years, technology revolutions can and do happen faster than expected. With the LED, two of the fastest-paced industries in history semiconductors and software have been introduced into the very traditional lighting industry. It would be hard to imagine in today's world that technology will not beat out tradition. In terms of dollars, Pike Research anticipates a transformation of the lighting industry that will result in LEDs displacing more than 52% of conventional lighting over the next ten years. This will have the effect of shrinking the value of the market due to the combination of rapidly falling LED 1

3 prices and the accompanying extended lamp lifetimes. Lamp and luminaire manufactures and others in the value chain will grow to rely on lighting controls and services to offset the revenue and profit lost in this process. 1.2 Market Influences According to the U.S. Energy Information Administration (EIA), global commercial lighting consumes approximately 1,500 TWh of electricity. Add industrial and outdoor stationary lighting, and that number grows to almost 3,500 TWh. To put that in perspective, 3,500 TWh represents more than the total electrical consumption of Africa, the Middle East, South and Central America, and all of Eastern Europe combined. An opportunity to conserve even a small portion of that will have enormous benefits. Improving lighting efficiency is an investment in the future. Like any investment, the upfront cost and the predictability of future benefits are the primary drivers in the decision process. Today, cost is a barrier to the adoption of more efficient lighting especially for LED lighting. Policy makers are playing a significant role in the cost of efficiency, both positively and negatively. Public funds are being used for rebates and subsidies to reduce the initial cost of installation. In many countries, the price of electricity is manipulated to either discourage consumption or encourage the adoption of new technology. Recently, supply policies in Asia have had a significant effect on the availability of fluorescent ballast components. As of this writing, China has restricted the export of rare earth elements, which has caused the price of phosphor to rise tenfold it now comprises 50% of the total cost of a fluorescent lamp. Uncertain economic and political situations have not slowed the private sector from investing heavily in the R&D of LED lighting. Pike Research projects that between 85% and 95% of development resources in the lighting industry are now focused on SSL products. LED technology is benefiting from this focus and costs are dropping quickly. In fact, costs are expected to drop at least 90% over Pike Research s 10-year forecast period. Demand for efficient lighting is being driven primarily by the adoption of strict energy codes. Reduced watts per square foot requirements are effectively banning less efficient incandescent and high-intensity discharge (HID) lamps. The green movement, despite flat electric rates, is strong. Energy certifications such as Leadership in Energy and Environmental Design (LEED) and BRE Environmental Assessment Method (BREEAM) are pulling better technology into the marketplace. Public projects at the local, state, and federal levels are also generating demand for cutting-edge products. However, more efficient and expensive lighting is not popular in every application. The highest volume segments (e.g., general office lighting) also typically include commodity lighting, where 2% to 3% profit margins are considered generous. These same areas have already been provided with relatively high-efficiency fluorescent products for the last ten years, so there is little incentive to spend more. Until LED prices come down to parity with commodity lighting, the smaller niche markets will be most attractive. Such markets include retail display, signage, low temperature applications, high-end specification, and theatrical markets, to name a few. Internationally, the trend toward efficiency is highly correlated to economic and infrastructure conditions. Europe and Asia are conservation-minded and open to government programs to limit consumption. The United States is highly segmented due to 2

4 state-driven codes and regional electric rate variations, and is comparatively new to the concept of conservation. Much, but not all of Africa, the Middle East, Latin America, and parts of Asia are working toward developing adequate infrastructure and are lagging behind in commercial lighting efficiency. 1.3 Technology Issues Efficacy, measured in lumens per watt (lm/w), and lamp life are the two most influential factors in determining the operating cost of lighting. But many other technical measures contribute to the overall quality of light, which cannot be sacrificed purely for cost savings. The ability of the lamp to render color accurately (color rendering index, or CRI) is important in most commercial applications involving retail and displays. The color temperature and spectrum given off by the lamp influences the occupant's mood and productivity, as well as the eye's perception of the light level. A dim but high quality light can yield a higher perceived illumination than a bright, low quality light. Compact fluorescents have efficiency advantages over incandescent, but have suffered in their early sales due to poor color and lifetime, as well as high costs. More recently, focus on the mercury content and disposal requirement has further diminished their appeal. Nevertheless, CFLs have overcome many technical issues and will be popular in the commercial market while LED development continues. LEDs are advancing rapidly in the area of heat dissipation and lumen output. The early issues with color have been overcome. More attention is on the design of the LED and luminaire into a single system rather than independent components. This will open the door to more creative and efficient use of the LED form factor. Ambient temperature is an important consideration for many fluorescent and LED applications. Fluorescent performance suffers at low temperature where LEDs thrive. Meanwhile, LEDs have color and lamp life issues at higher temperatures. Other factors that are explored in this report are the advantages of low-voltage DC current, the influence of AC voltage and inrush current, and finally the importance of lighting controls. 3

5 1.4 Market Forecast Pike Research estimates the global market for commercial lighting will reach $42 billion in 2011 and see a peak of nearly $54 billion in 2012 before gradually declining to about $30 billion by The decline will be due to the extended lamp life of both fluorescents and LEDs as they become the primary lamp types over less efficient and shorter-lived incandescent lamps.

Incandescent and less efficient T12 and T8 fluorescent lamps will be almost completely eliminated over the next ten years. To take more than 50% of the market, the LED will take share from CFLs, HID lighting, and general linear fluorescents.
