In September 2009, the European Union prohibited department stores from selling incandescent bulbs, which triggered an immediate interest in economic LED bulbs. On the one hand, this transition was determined by the decision of the EU; on the other hand, these bulbs have lower energy consumption and save considerable amounts of money on bills. In order to better understand the difference between LED bulbs and incandescent bulbs and why the former are superior to the latter, we should find understand how both these bulbs work. When we switch on the light, the electrical current passes through the Wolfram filament, this metal withstanding very high temperatures of up to 3000°C. To produce light, the filament must be heated to a temperature of about 2300°C, and this process converts only 5-10% of the energy into visible light. The rest of the energy is turned into heat, which at one point could lead to an unwanted rise of the temperature in the room. Unlike the traditional incandescent bulb, the LED bulb, or ampoule LED, as it is called in French, is made of small glass tubes filled with a special gas and an amount of mercury that is 100 times lower than the one found in old thermometers. Light is produced when the tiny mercury molecules from inside the tube react with the electrical current that flows through the two electrodes at the base of the bulb. Mercury produces an invisible ultraviolet light which becomes visible when it touches the interior walls of the tube. A simple conversion with an online energy saving calculator reveals astounding facts: by replacing 10 75W incandescent bulbs with their equivalent in LED bulbs or ampoule flamme, users can save considerable amounts of money each year because the bills are much lower. In addition, by keeping a LED bulb switched on for 3 hours/day, residents can reduce energy consumption to 600kWh per year. More than just a way of saving money, this a responsible, eco-friendly alternative that helps lower greenhouse gases with about 400kg/year. An economic LED bulb uses 70-75% less energy than an incandescent bulb and is not expensive at all, which makes it a wise, sustainable alternative in any home or office. When comparing flourescent bulbs with regular bulbs, another thing that should be pointed out is the fact that LED bulbs last up to 10 times more and it’s not uncommon for such a bulb to function for 5, even 10 years. An economic bulb doesn’t heat up as much as an incandescent one. This means that we don’t have a temperature limit because of the material the lamp is made of and there won’t be an explosion every time the bulb comes into contact with water. In the case of incandescent bulbs, 80% of the consumed power is lost through heat and IR and UV radiations, but economic bulbs don’t have this problem. In the past, fluorescent bulbs were criticized because of their harsh and unnatural light tones, but things are different today. Manufacturers offer a much wider array of bulbs with various types of light and the quality of light is clearly superior to the ones produced by incandescent bulbs.
