How Are Energy-Efficient Light Bulbs Made?
Introduction Energy-efficiency has become a large concern all over the world. Many machines and appliances have been redesigned in order to reduce energy consumption and increase efficiency. One example is the light bulb. Light bulbs have been remodeled after the design of long fluorescent tubes to create a light bulb that fits a standard lamp but lasts longer and uses less energy than traditional incandescent bulbs. The process of making them required some alterations in the manufacturing process. The Difference in Design Traditional incandescent lights worked by heating up a metal filament–normally tungsten–that would then start to glow from the heat. The light emanating from it is amplified and spread out via the glass enclosure of the bulb. It requires a lot of energy to heat the filament enough to glow. The metal also burns out quickly compared to fluorescent bulbs. Incandescent bulbs only emit 5 percent of the energy put into them and burn out after 1,500 hours on average, whil
