Incandescent light bulbs will be in use for the last one century, but now with the advent of technology they've become out-of-date. The main disadvantage associated with incandescent bulbs is which almost than 80% energy supplied to them is wasted as warmth energy in support of 20% is changed into light for which they are made. Also they provide light of only one color that is yellow which makes them unsuitable for additional purposes such as indicators, decoration etc. One additional disadvantage is actually their life span which is just about 1200 several hours which creates a require of changing them oftenIt is very obvious that sooner or later we will face a power crisis and therefore this factor of power wastage offers made people all around the globe to consider an option for these incandescent lights. Compact Fluorescent Lamps (CFLs) are e much better option over these incandescent bulbs that have a life span of about 6000 several hours and consume no more than 1/5th of the energy that's consumed through incandescent lights for generating the light of same intensity. But the recent technology that has attracted the interest of everyone is the Led bulb (Light Emitting Diodes) that have lifespan of 50, 000 hours and consumes even lesser power compared to CFLs.
