Completed Work Task 1: Compare compact fluorescent light bulbs to incandescent light bulbs. In order to begin our research, we first had to prove that our current light bulbs are not the cheapest and not the most efficient choice to light up our buildings. Otherwise, it would have been useless for us to continue. We began our research using government documents, electronic books, and websites that compare incandescent light bulbs to other types of light bulbs. Ballast describes incandescent lamps as sealed bulbs which contain a filament and Argon gas. When current passes through the light bulb, the tungsten filament heats up and glows. This light bulb type is known to be cheap, small, and easy and fast to light. The major disadvantages of…show more content…
When the invisible UV light hits the coating of the bulb, the phosphor coating transforms the invisible light into light you can see. (U.S. EPA and U.S. DOE) There is no heating up of the filament, so the energy is usually not lost due to heat like when you use an incandescent lamp. The advantages and disadvantages of CFL will be researched in more detail in the next two tasks. The U.S. Environmental Protection Agency and U.S. Department of Energy ENERGY STAR® website provides a table, Table 1, which compares the two types of light…show more content…
According to Table 1, incandescent light bulbs claim to have a lifetime between 750 and 1,000 hours. Incandescent light bulbs will give us between 80 and 110 days of life. However, this is an imperfect world, and many factors such as temperature and vibrations of the surroundings can shorten the lives of light bulbs significantly. Let us assume that an incandescent light has a lifetime of three months. A burned out lamp costs our company money. When a light bulb goes out in a room, not only does the company lose money to replace that light bulb but the company’s efficiency decreases as well. The workers in that office have to stop their work to report the burned out light bulb, and our custodians have to stop their work for about 10 minutes in order to go change the light bulb. If this happens every three months in a period of two years, the custodians will have spent six hours replacing light
