No, of course not. You just have to be careful not to knock it or flick the switch for it repetitively or the fuse will blow. If the fuse blows the light will not work anymore.
A bulb will last about six months before it needs to be changed again. Continuously turning a bulb on and off will decrease its' life span, however the average life span is about 5,000 hours per bulb.
"Under normal usage, a GU10 LED light bulb will last 25 years. This equates to about 50,000 hours and is a very cost-effective and low energy light bulb."
Over all, CFL light bulbs are good for the environment and they can save $. 1 CFL light bulb has 10 times the life span of a regular light bulb. 1 CFL light bulb could save enough energy to take a car from NY to San Francisco. 1 CFL light bulb uses between 50% and 80% less energy than a regular light bulb.
we use the light bulb in every day life
By bulb, it is assumed a light bulb is intended rather than a flower bulb or any other kind of bulb. Light bulbs burn out because they are engineered to do so. There would be less profit to the bulb manufacturer if he made bulbs to last longer, which he could if he wanted to. In the early days of bulb manufacture, a bulb was made which still continues to burn over 110 years later. See the link below for more information on the 110 year bulb.

The mood light will last as long as the bulbs life, which has a lifetime of an average household light bulb. once the bulb burns out, one must replace the bulb with another mood light bulb.
Be careful not to handle the bulb with your bare hands. The grease from your fingers will effect the life span of the bulb.

Answer Actually dimmer switches extend the life of a light bulb, especially if you dim them often.
Yes, we could still live without the light bulb as there are alternative sources of light such as candles, oil lamps, and natural daylight. The light bulb has made life more convenient and efficient, but it is not a necessity for survival.
That can vary A LOT, depending on the specific technology used (the type of light bulb), and the brand.
