The Evolution and Impact of Incandescent Light Bulbs in the United Kingdom

1. Introduction to Incandescent Light Bulbs

Incandescent filaments produce light by heating to high temperatures. Any solid, including carbon, if heated sufficiently, undergoes what is termed "incandescence," emitting electromagnetic radiation. Incandescent lighting technology has been developed using a number of materials for the filament, including tantalum and osmium. The science of incandescence and the historical and modern technology of the manufacture and application of incandescent light sources are the subjects of this chapter. The successful collection of economic sparse data at the national and firm level using business history and the successful reduction of the dimension of the actual collective big collections with the "matrix model" developed by economic historians means this story is told differently than most industrial and economic histories that use firm level data but are unable to connect up the firm data with the firm's specific markets, industrial organization, and technology. With the light bulb industry invented in England, largely invented by mainly London-based innovative firms, and with the rest of this industry organized with subsidiary presences in the UK but with firms heavily invested in markets and full-scale firms engaged in cross-border foreign direct investment, trade, and cartel-joint-ventures, this is also a chapter in British business history.

2. Technological Development and Innovation

Research advances as of 1879 have been inspected from Rawlo's notes made in the early 1940s, which augment later published work. When that research was done, the essential primary records were relatively easily accessed and well understood because the work was conducted under those precise circumstances of incandescent lighting after it had been significantly developed. (i.e., the many difficulties and anomalies had been resolved). However, fifty plus years after it was introduced to the public, numerous myths were identified and dismissed, and the circumstances of several of the developments had their exact occurrence recalled. An accurate overall perspective was granted to such research immediately because fine detail could be added. Fifty years on, that precise perspective no longer exists, and aside from citations in numerous patent literature and biographic references, Rawlo's work on incandescent lamps predating 1879 had remained largely and unjustly overlooked.

British public experiments using massive electrical discharges are recorded from 1747. The production of continuous electrical illumination began in 1800, and a new intense illumination was achieved in 1844. In 1879, incandescent lighting was a startling development, and incandescent bulbs dazzled sight when introduced to the public.

3. Environmental Impact and Regulations in the UK

Town Planning Regulations constraining greenhouse gas emissions into building energy ratings from 2008 compelled the owner of the household and landlord to install energy efficiency improvements.

All working and residential consumers in the UK can then make informed decisions on the take-up of incorporated energy-saving technologies, thereby reducing energy costs and contributing to carbon and other harmful gas emission reductions. The evolution of the electricity supply industry in the United Kingdom became an unstable moving target from 1990 until 2008, when the domestic, commercial, and industrial consumer realized this advantage with the inflation of the suppliers "fuel mix" charge as shown in Figure 6. Remember that "fuel mix" accounting for electricity supply companies corrupted the transparency of fossil fuel consumption as shown in Figure 6, so it became clear that the increase in costs was due to the operation of a complex and costly emissions trading scheme.

The predictability of regulated electricity costs is fundamental to both large and smaller-scale electricity consuming and generating entities. Electricity generating companies need to have a very clear understanding of all the fixed and marginal supply costs to select the most cost-effective generation plant mix after assessing risks. All sector commercial consumers, irrespective of location in the UK, and the non-domestic sector need a clear view of the regulated future prices for price planning, evaluating cost benefits for investment in both energy consuming and energy efficient office and industrial equipment and machinery, and future business planning.

This section refines the perspective of the two previous sections, showing greenhouse gas emission data and the regulatory changes that they face in the near future. This issue is significant to address the debates in the subsequent sections in relation to energy efficiency. Tables 3 and 4 show current and future UK greenhouse gas emissions and associated pollutants, respectively, from electricity generation.

The invention of the carbon filament light bulb and the tungsten filament light bulb by Thomas Edison and his research team in the United States in 1879 was a major breakthrough in electricity generation and utilization. The lighting industry became a significant part of electricity generation and demand, which it remains today. The long-term environmental impact of the light bulb is related to electricity generation and the materials it consumes. Each stage of the life of a light bulb has a direct or indirect effect on emissions, the environment, and human health, which is the foundation for government and societal regulation and influence.

4. Transition to Energy-Efficient Lighting Technologies

Today's energy-saving alternative to incandescent lamps is solid-state lighting. LEDs as light sources exploit the transistor or metal-oxide-semiconductor field-effect transistor electromagnetic principle, enabling not only convenient continuous changes to a supplied electric current, but also pulsed modulation. This allows independent control of an array of solid-state emitters for both color and intensity, making LEDs highly electrically effective and able to provide an outstanding color range. Ideal light quality, the narrow bandwidth, and precise light control throughout their life allow for exciting choices that were unthinkable with incandescent lamps.

Following the introduction of the Energy Efficiency Directive, there was a notable development of efficient alternative lighting technologies. Besides most forms of phosphor-coated fluorescent tubes, compact fluorescent lamps (CFLs) presently offer an ultra-efficient form of illumination. Electronic controls, which on the one hand prevent illumination from flickering and give linear varying control over the electric current presented to the source, and on the other lower the 50 or 60 Hz frequency of the supplied electricity, enable practical and reliable domestic use of CFLs. When the popular linear light pressure tetrodes, or rather electrified fireflies, offer typical light quality and color rendition, significant reductions in heat gain compensate for initial costs. Although technological developments continue to promise improvements in light output and color rendition, today's CFLs' proliferation highlights their competitive advantage over other light sources, even LED-based lights.

5. Conclusion and Future Prospects

The future for the industry may appear to be bleak, with an immediate decline expected following the introduction of compact fluorescent and light-emitting diode bulbs. However, as the historical evidence presented in this paper suggests, there are deep-rooted cultural and social reasons why people like these bulbs. Hence, it is unlikely that their disappearance will be as rapid as currently projected. First, light-emitting diode bulbs are simply too expensive; compact fluorescent bulbs simply flicker for too long before delivering adequate light; and both types of bulbs are not accurate enough in terms of delivering light that accurately matches the dimming needs of households. Second, customers do not like the fact that they contain mercury. Finally, the lighting industry has developed an important new concept: the 'magic of light'. Firms in the lighting industry argue that the magic and cultural value of light means that shoppers will once again search for affordable, reliable, quality light bulbs through attractive, innovative designs that are easy to produce, install, and maintain. It is these needs and preferences that the industry would do well to respect if they are to deliver efficient and cost-effective policy, in terms of both sustainable development and economic growth.

This paper investigates the subsequent evolution of the light bulb industry following the introduction of incandescent bulbs to the UK in 1881. The analysis offers an important insight into the post-introduction competition phase in an industry that offers little scope for the application of self-replacing characteristics for non-durable goods. Instead of the technological improvement of quality or a drop in price, competition was based on a plethora of advertising and marketing methods that were consistently discriminatory and to some extent likely to have been wasteful. The light bulb industry in both Europe and the US was innovative in brand development and the introduction of new techniques for the marketing of consumer goods, which were subsequently employed more widely by firms in all industries. The organization of firms was rapidly transformed from an era when light bulbs were publicly promoted as free market evolution goods through a series of restrictive practices to a pair of vertically integrated entities in Europe and the slightly less oligopolistic model in America. These duopolistic forms persisted for most of the twentieth century and were characterized by high levels of concentration, standardized products and pervasive product classification systems.

The Phasing Out of Old Incandescent Lamps: Reasons and Impacts

1. Introduction

Incandescent lighting was a major source of lighting in the 20th century. The "old incandescent lamp" is what we see today in many households. However, with growing concerns for overpopulation, finite resources, the environment, and terrorism, there are now many reasons for making the transition to a sustainable lighting option. One of the answers is better energy management, marking the beginning of a journey into solid-state lighting. The "old incandescent lamp" dates back to the late 1860s and is the least efficient lamp of all currently available. The lamp consists of a thin metal filament made of tungsten, which is heated until it reaches a high temperature, producing light and some infrared radiation. At least 95% of the lamp’s energy input is emitted as heat. There are several different options on the market today, which will aid people in this transition from traditional lighting forever. These include: CFL - compact fluorescent lamps; LED - light-emitting diodes; and OLED - organic light-emitting diodes. This scientific essay will look into the reasons "why" and "what" got us on this journey toward lighting for the future for residential purposes. The focus is mainly on the reasons and impacts behind this conversion toward a safer, alternative technology for lighting for ourselves: the environment (due to incandescent light bulb manufacturing and disposal); "someone else" (related to human population growth and consumption); the energy generation industry; and our quality of life. This essay report will discuss the reasoning behind stopping the production of traditional incandescent lamps and how this would affect the people and governments of various countries, lighting manufacturers, and the people of those countries.

2. Environmental Impact and Energy Efficiency

The failure of a traditional incandescent lighting lamp to keep pace with advances made in energy saving and emissions reductions is one of the reasons for this phase-out decision. The incandescent lamps were only 7% efficient at converting electrical power, and more than 90% of the power was lost as waste heat. Roughly 10% of the average home's energy bill is directly related to lighting, although this figure may vary based on electricity cost. The energy efficiency and environmental profile of light-emitting diodes (LEDs) continue to improve, and they now have the potential to rapidly replace traditional incandescent lamps. When incandescent lamps are replaced by the much more energy-efficient solid-state LED alternative, the overall demand for energy would decrease significantly.

The phasing out of these less efficient incandescent lamps would open up opportunities for further investment in solid-state lighting and contribute to the wider energy security picture by reducing the need for new energy production or transportation. Planning a phase-out of old incandescent technologies has been made increasingly on the environmental grounds of reducing greenhouse gas emissions, with energy security implications, and is considered a necessary part of a rapid, worldwide response to climate change. This is because traditional incandescent lighting uses more energy than other forms of lighting. Increased power generation will require more fuel burning, leading to greater carbon emissions and negative changes in the global climate. There is evidence to show that incandescent lighting affects climate change, which in turn could have further impacts on our natural ecosystems. Therefore, the more power-efficient forms of lighting, such as solid-state LEDs, are favored, both in the home and in industry and businesses, as part of modern energy management.

3. Technological Advancements in Lighting

There have been several advances in lighting technology in the last few years that are more energy-efficient than traditional lamps. Research and development efforts in the lighting industry have yielded several technologies that are able to replace energy-inefficient incandescent lamps. Energy-efficient alternative technologies include compact fluorescent lamps, light-emitting diode lamps, and electrodeless induction technologies. Advances in lighting technologies have also expanded into smart lighting. Smart lighting technology uses automated systems that receive inputs using wireless communication capabilities for accurate remote management of lighting systems. The advent of increased lighting technology has made the industry very dynamic, and companies that invest in technology are more likely to become established.

Key research areas, and likely areas of growth, for the lighting sector include materials, manufacturing, and lighting regulations. Each of these areas has the potential to drive changes in the lighting sector, either by product cost reductions, increased product innovation, or changes in consumer acceptance. Overall, ongoing research and development in the lighting industry will eventually lead to the replacement of all incandescent lamps with energy-efficient alternatives. Technological shifts have been shown to drive consumer acceptance of new products, and the lighting sector is no exception. If energy-efficient alternatives had not been developed, consumers would still be purchasing incandescent lamps, and many governments would not be setting policies and regulations to phase out energy-inefficient lamps.

4. Regulatory Measures and Policy Changes

Several regulations and policy initiatives aimed at phasing out incandescent lamps are in place. Suggested values for the maximum allowed wattage and light output per watt for the most common light bulb types are published. A Model Regulation Guideline for phase-out regulations outlines the elements of light source policies such as requirements for manufacturers, importers, and retailers, quality standards for alternative technologies, as well as specifications and test methods. The government has the authority to set minimum efficiency standards for all new lights sold, such as fluorescent systems, incandescent, and halogen lamps. Regulations requiring general service lamps to meet a minimum energy efficiency standard are also presently being considered. Other jurisdictions with policy measures to phase out inefficient incandescent lamps include various countries, while a number of Asian countries are currently considering policy interventions.

Given these examples pertaining to the uniqueness of the local or regional context of policy implementations, there are still common varied designs in the three basic types of regulations in place, namely outright bans, efficiency standards, and bans on certain types of lamps. In the U.S., a long-standing ban on some brightness of incandescents was upheld for a new period. At the same time, traditional reflector and floodlight upgrades to meet energy efficiency requirements were ordered, and targeted advocacy was proposed. There was a report to Congress that was supposed to be generated by the end of a certain year. In the lighting industry, there were few that knew that there was a regulation in place; there was no enforcement and no actions to comply. Regulatory measures of this type have moved softly and made a big impact in energy-consuming areas.

The Department of Energy, through a variety of programs, has successfully hit the national goal of a significant electricity efficiency derived from functioning contracts/programs and the market of commercial and industrial lighting products. The purpose of this activity is to move regulation towards specific policy requirements. It is possible that Congress is divided on this issue and the Department of Energy wants to please both sides. Another type of policy is an outright ban on the sale of incandescents for general use on a certain date. Both of these first two initiatives have met with legal challenges and have been delayed. In certain regions, there is a regulation strictly defining incandescent efficiency. Requirements for minimum lamp efficacy are also in place. Policy is not in place in the developing world or Asia. With every desktop lamp a T-shape, what happens to innovation in reflector lamp lighting? Some parts of the world require certain materials in the fluorescent lamp to be collected and recycled, which is ideal. A similar uproar to the one caused by certain materials in power-saving tubes has yet to occur with the incandescent lamp, universal use, or even local applications.

5. Consumer Preferences and Market Trends

Compared with a decade ago, consumer preferences for lighting solutions and their factors of influence have undergone several changes. Awareness and changes in consumer purchase factors support energy-efficient lighting solutions. A variety of discussions have addressed the factors that influence the substitution of lamps and luminaires and have conducted consumer surveys. Over the last decade, marketing strategies, in particular, the role of education and consumer empowerment have shifted the demand for lighting products, especially in the domestic lighting market. Consumer awareness about the effect of efficient lighting on electric consumption has become relevant. Even consumers who are not able to calculate the direct economic benefit of each LED solution can show a preference for low energy consumption because they consider it efficient not to waste electricity or sustain an environmentally sustainable solution. Available statistics show a stable trend or an absolute annual improvement of greater than 5% in the sales of LED solutions at the expense of incandescent solutions. The local projection of statistics is often not clear, but it supports the feasibility of nationally valid data.

Most LED sales are concentrated in a few countries, with Germany, the USA, and China topping the list. In the USA, consumers only accept LED solutions because no other luminosity generation solution is available commercially in retail outlets. Available data on lighting market trends can aid lighting manufacturers and retailers in matching demand for the variety of lighting solutions available and more frequently promoting LED solutions, or for policymakers to better understand market trends for the phase-out of incandescent lamps. Consumer purchasing behavior is one of the most relevant company concerns. From the beginning of this century, consumer purchasing behavior has been receiving increasing attention in identifying preferences within a given market. In cases of global supply commodities such as lighting, the impact of product availability and attractiveness is of primary influence. The purchaser preferences with regard to product features influence, in principle, the producer's ability to market a given product to maximize sales and the product's share of the market. Conversely, consumer purchasing behavior also influences the product manufacturers in their capacity and decisions concerning market offerings.
