Why are compact fluorescent bulbs different from incandescent bulbs?
 Incandescent bulbs are the sta type of bulbs that were most comm some years back. Incandescent light are made of glass, and are round in s They work by heating a tungsten fila or wire, until it glows. This is what pro the light that you see. Unfortunate') of the energy used to generate that I wasted as heat, making incandescent a very inefficient way to light your ho Instead of a glowing filament, CFLs contain argon and mercury oused within a tube In different shapes. electric current passes the mixture, the gas ted, and it produces t light. The ultraviolet turn, stimulates a nt coating painted on e of the tube. As this bsorbs energy, it emits ht. it a longer time than :ent bulbs. In some tests, they burned brightly for 10,000 hours, whereas standard bulbs burned for just 800 to 1,500 hours. CFLs use signifi-cantly less energy - 75 percent less energy than incandescent light bulbs. This means that by using CFLs, you are not only saving electricity, but also helping the environment by reducing energy consumption and preventing greenhouse gas emissions that contribute to global climate change.
