Long Life for Electric Bulbs

  Over the number of years that I have lived, I have realized that, most of the time we loose filament of electric bulbs is while switching the bulb on. That must be because of sudden heating of cold filament to an instant brightness. So if we create a second electric bulb holder that fits on any existing bulb holder such that it doesn't instantly ignite the bulb to full brightness but rather smoothly increases the electric current to the fullest, then we would save a lot of money and resources of producing electric bulbs. And poorer areas where only bulbs are used will be glad to buy such a product.
