When you think about lighting, it’s important to think of three different things: the fuel source, the luminaire, and the technology used to produce visible light. We’ll touch on those three items as we look at the evolution of lighting from its birth to the modern-day revolution that is happening with 21st-century LED technology: The first lamp was invented made of a shell, hollowed-out rock, or other similar non-flammable objects which was filled with combustible material (probably dried grass or wood), sprinkled with animal fat (the original lighter fluid) and ignited.” Handheld and building-mounted torches progressed well beyond their rudimentary start but the basic principles remain the same: the fuel source is some type of oil, wax, or combustible material surrounded by non-flammable material. But it wasn’t until 4500 BC that humanity would be able to sustain a light source without managing it. This was when the basic oil lamp was invented which was then followed by the candle in 3500 BC. Before electricity, lamps were the focus of development by inventors. Year: 1780 But then the Argand lamp was invented in 1780 and it became a must-have product in 18th-century Paris. This was because the lamp was much more efficient and it generated ten times the light that a single candle could. The next major advancements in lighting (gas lamps and electric lamps) happened in sequence nearly a century apart with the advent and progress of the industrial revolution. In 1792, the first gas lamp was invented by William Murdoch which revolutionized the use and evolution of lighting outside of the home. Major advantages for gas (barriers to entry for electricity) included the already existing infrastructure by the time electric lights came out and the ability for dual-purpose use (gas could also be used for cooking) Year: 1790 Gas lighting was developed in England in 1790 and introduced to the United States shortly thereafter by William Murdoch. Pelham Street in Newport, Rhode Island was the first section of road in America to introduce Murdoch’s gas lights (they were installed in 1792). Only a few decades later gas fuel was being used for street lighting in major eastern cities of the United States like Philadelphia and Baltimore. You can read the full history of street lighting in the USA here. Different types of gas have been used over the years to include methane, acetylene, butane, propane, hydrogen, and natural gas. The growth of gas lamps and the infrastructure to support them in cities and suburbs mirrored the advancements of the era in hydrocarbon fuel production (coal and petroleum production and distillation). Before the 19th century, factory work was perilous. Early cotton mills relied on water or steam engines and any stray machinery could harm a worker if they couldn’t properly repair it. It was Philips and Lee’s cotton mill in Salford that began to change this by employing gas lamps. Humphrey Davy’s safety mining lamp allowed coal miners to avoid setting alight the flammable methane which existed naturally within the mine. Without the new lamp, mining operations were deadly and many workers died. These early improvements saved countless lives in dangerous industries and minimized injury even more. For modern offices and businesses, the story was different. It wasn’t until the invention of electricity that the world of work changed forever. Year: 1880 The first electric light was created by Englishman Humphry Davey. According to the US Department of Energy Davy “demonstrated the first incandescent light to the Royal Institute in Great Britain, using a bank of batteries and two charcoal rods. ”His invention was what we commonly refer to as an arc light (modern-day versions of which are still being used today). After electricity was made available to homes and businesses on a city level, traditional methods of illumination slowly lost their market share. They weren’t a viable option anymore after 1880 when Thomas Edison patented a bulb that could last for 1500 hours. Though his first successful prototype was on October 22, 1879, when his incandescent light burned for 13 and a half hours, A few months after that, Edison discovered a carbonized bamboo filament that would burn for 1200 hours Incandescent bulbs would go on to dominate the world of lighting until fluorescent lights were introduced commercially by Daniel McFarlan Moore Year: 1904 Although early fluorescent lights required high voltage and non-standard connectors to operate, their relatively high efficiency when compared to incandescent lights was significant enough competition to cause major incandescent manufacturer General Electric to improve upon their incandescent technology by introducing the tungsten filament. Concurrently (circa 1901) an inventor named Peter Cooper Hewitt developed the first mercury-vapor light that was both high efficiency and compatible with standard electrical infrastructure. The 20th century was the century of high-intensity discharge (HID) lamps. Amongst the most popular and commercially successful types of HID lamps are fluorescent, mercury-vapor, high-pressure sodium, and metal-halide. All of these lamps are the same type of technology in that they operate by sending an electrical current between two metal electrodes and through a glass tube filled with inert gas resulting in the emission of visible light. Modern lighting has continued to improve across the spectrum (incandescent, fluorescent, metal halide, LED, etc.). Thus far the most promising lights for the 21st century appear to be LEDs. Modern LEDs have a useful lifespan of 2-4 times that of their average competitor while producing high-quality light much more efficiently as well.

LED lighting offers a number of benefits to industrial and commercial facilities interested in reducing energy use and costs. Whether you are looking for increased energy efficiency, easier maintenance, or improved environmental performance in lighting technology, LED lighting is the solution for you. If you have exterior lights that are left on long term, using CFLs or LEDs in those fixtures can save you tons of power. This also makes LED lights extremely helpful to use outside, where other lighting solutions may not comply with local codes. Their ability to work so effectively in cold weather also makes them an ideal choice for lighting in parking lots, lights used to light up building perimeters, and lights used for outdoor signage. Flood lights are tested to survive in the rain and snow, and so they are suitable for use in exposed fixtures. To create a white light, various colored LEDs are combined or coated with phosphor materials, which transforms the colors of the light into a familiar white light used in homes. There are also hybrid approaches, in which non-traditional bulbs or replacement format of the light source are used, and are designed specifically for the unique fixtures. This also means complex engineering is required to manufacture an LED bulb which emits light in all directions. As shown in the chart to the right, an LED light bulb for general purposes, which does not meet the ENERGY STAR requirements, might not spread the light everywhere, and might turn out to be a disappointment when used in a desk lamp. For more information about choosing an ENERGY STAR-certified bulb for every application in your home, check out the ENERGY STAR Bulb Shopping Guide or use the interactive online Choose-a-Light tool. You can find many more ways to make your home more energy-efficient than the ones covered in this book, I am giving you my best. Energy-efficient helps you make changes in the lifestyle of your household in order to save money and energy, as well as to cut down on pollution. This book gives you an extensive understanding of the concepts behind energy efficiency and costs so that your house becomes an efficient wonder. Possibilities* Improving a raters competence could come from a combination of improving the industry's standards for care, as well as training and professional development offerings that are accessible to all. Particular attention is given to how energy and environmental policymakers and other stakeholders beyond the appraiser community can contribute to the larger effort to promote best practices. Other challenges that are overcome include limitations in the understanding of the evaluation process by those who are not part of the evaluation profession (and practical constraints in doing so). A byproduct of this may be unrealistic expectations about what an appraiser can and will do on the market. While the green/HP community has encouraged assessors to focus on model buildings (e.g., LEED-certified or Energy Star-certified), any level of greenness or energy efficiency may actually affect values, including sub-par (i.e.) Led is very energy efficient and helps improving the the world The lifetime of LED lighting products is defined differently from other lighting sources, such as incandescent or compact fluorescent lights (CFLs). Many conventional light sources, such as incandescent bulbs, convert over 90% of the energy they use into heat, allocating just 10% of energy for the actual light output. A typical incandescent bulb only converts 10% of input electrical energy to light power; the rest goes into heat. You do not need to crank your inefficient heating system quite as often, so using incandescent bulbs during the winter is a very efficient process. An image of an incandescent Edison light bulb Right now, solar is just 0.06 percent of the power generation (if you exclude all of the natural light and heat that the sun produces), but this is changing rapidly. You can measure a lights efficiency in utility Lumens, which describes how much light the device produces per unit of energy, or Watt, that the bulb uses. How expensive an energy source is depends on what it takes to get power into your house (raw power costs) and what it takes to turn the raw energy into fuel that you can use (conversion costs). Part | Solving World Problems From Your Front Porch The Fifth Wave By Rich Tennant One thing we do to save power around our house is make sure that all of our lights are turned off before going to bed. Next Gen Utility Lights Ready To Shine The version B of RULs leading utility light is here: updated with the latest technologies including expanded lumen levels and voltage ranges, improved energy efficiency, and a seven-pin NEMA-rated receptacle option.
