How much light bulbs are in a Colombian house?

What is difference between regular household light bulbs and led bulbs?
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.
How much money did Thomas Edison make in his first year selling light bulbs?
Thomas Edison got $3000000000 in his whole lifespan of selling light bulbs
How many light bulbs are used in a household in one year?
According to fastcompany.com: "Last year, U.S. consumers spent about $1 billion to buy about 2 billion lightbulbs--5.5 million every day." According to wsj.com: "The U.S., which has four billion electric lights using [incandescent] bulbs, represents about a third of the world market." So, about 12 billion bulbs, worldwide.
Which light bulb is best for cost saving?
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.
What is it that normal light bulbs give off much more than fluorescent light bulbs?
Heat.
How much percent of the worlds electricity is from light bulbs?
None. Light bulbs use electricity, they do not create electricity.
How have new light bulbs changed inside from old ones?
With Thomas Alva Edison's invention of the light bulb, the elements were constructed of Carbon. Newer light bulbs are constructed of Tungsten, which takes much longer to bend into a coil within a coil within a coil, but shines much brighter and lasts for thousands of hours.

Why does an LED light cost so much?
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.

Where is there a resister in a light bulb circuit?
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.

How much solar power does a 40 watt light bulb use?
two 40 watt bulbs in 24 hours use: 2*40*24 watt hours in practical uses, kilowatt hours are used divide by 1000 to change the units thus two 40 watt bulbs in 24 hours use 1.92 kilowatt hours
Are light bulbs really efficient?
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
How are xenon bulbs different from normal light bulbs?
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.
How much energy can you save with buying new light bulbs?
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.
