LED light bulbs definitely are more energy efficient than regularly normal light bulbs. Depending on the usage, LED lights can also last maybe twice or three times as much as regular bulbs. LED ones are better.

Florescent light bulbs produce a similar amount of light with much less power than incandescent light bulbs. Their initial cost is paid back in energy savings. They also last a lot longer. I exchanged every light in my house for florescent bulbs years ago and I haven't changed more than 4 or 5 in all that time. LED bulbs are now on the market and are very expensive. But they use even less power to produce similar light and last many times longer than florescent bulbs. They are quite expensive, but what you get is an almost permanent bulb. In the future we will tell our grandchildren how we used to change light bulbs and they won't understand. I see a day when the bulbs become permanent parts of light fixtures and will not be replaceable in any typical sense.
If light bulbs are burning out quickly the light fixture could be getting too much electricity due to faulty wiring. They could also burn out due to a loose wire or screwing the light bulb in too tight.
Heat.
None. Light bulbs use electricity, they do not create electricity.
LED bulbs cost so much because of the amount of life that you get from the bulbs. These bulbs are designed to last for years.

In an old-fashioned light bulb, the part that emits light is a resistance. When current flows through it, it heats up so much that it glows - it emits light.Due to their lousy efficiency, these light bulbs should be discarded, in favor of fluorescent light bulbs or LED light bulbs.In an old-fashioned light bulb, the part that emits light is a resistance.

Normal incandescent bulbs produce a lot of heat as well as light, so are not so efficient as low energy bulbs which can give the same light but consume much less electricity

Xenon bulbs are much brighter than regular light bulbs. They are more expensive that normal light bulbs. this is partly because of the cost of xenon gas, but also because of the heat generated by the bulb that requires them to be housed in quartz instead of glass.
By buying and using new LED light bulbs, it is possible to save 12% of energy which is 90% more effective than other light bulbs and can save about $26.

It has enough power for 150,000,000 light bulbs.
