∙ 8y agoThe wattage rating of a bulb is in direct relation to its energy usage per unit time. A 100 watt bulb consumes twice as much energy as a 50 watt bulb over the same period. Keep in mind that the latest generation of energy saving bulbs (Compact Fluorescent Lamp) can be labeled both how much energy they actually consume, and also by how much light they produce as compared to an incandescent bulb. For instance, a CFL rated at 60 watts equivalent consumes only 14 watts. In other words, it only takes 14 watts from a CFL to produce the light equal to a 60 watt incandescent bulb.

Do dimmer switches reduce bulb life?
Answer Actually dimmer switches extend the life of a light bulb, especially if you dim them often.
HOW did the light bulb make life better?
The light bulb is safer and easier to use than gas lamps, and electricity is easier to distribute for the purpose of street/home lighting than gas. A cheaper, safer, and easier means of bringing light to the darkness was born with its invention.
What is the hottest light bulb?
There are two main types of commercially available energy-efficient light bulbs. These are LEDs and CFLs. Both are better than traditional incandescent light bulbs when it comes to energy efficiencyThe efficiency of light bulbs is calculated by comparing the amount of light produced to the amount of energy consumed:LED bulbs produce 90 to 112 lumens per watt.Compact fluorescent lamps or CFLs produce 40 to 70 lumens per watt.Traditional incandescent bulb fixtures only produce 10 to 17 lumens per watt.There are other considerations: Compact fluorescent light bulbs have a life span of eight to 10 years and cost about $4 per bulb.LED bulbs last up to 40 or 50 years but can cost over $306 per bulb.CFLs contain mercury which may require special handling for disposal while LEDs do not.
How long will an Aerogarden bulb last?
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.
How has the light bulb improved?
What would our life be without the light bulb? Our world would be different. If you were at school you wouldn't be able to see what you are writing in writing class. At night it would be pitch black. The only light you would receive would be from the sun hitting the ground. The light bulb helps our world a lot. If Mr. Edison wouldn't have improved the light bulb, we would be using unsafe candles. Life was very hard before the light bulb was invented. It was hard because without the light bulb, people couldn't see and had to use fire for light. The inventor of the first light bulb was named Joseph Wilson Swan. If Swan didn't invent the light bulb, then Thomas Edison would be in trouble. The light bulb Swan invented was not lasting very long. It would turn on for a few seconds, and would burn out. Thomas Edison wanted to make a new and improved light bulb for the whole world to use. Before people had light bulbs they used candles. Candles are very dangerous because if you leave a candle on at night, chances were that it could burn your house. A new invention came along called the arc light. The inventor stopped the use of the arc light. They stopped using it because when the people installed this light, it would give off a toxic smell that would affect the human body. People thought of installing the oil lamps in homes, but it was too dangerous. Joseph Wilson Swan was the inventor of the first light bulb. Thomas Edison improved the light bulb. The original one was not lighting properly. Edison goal was to improve the light bulb because he wanted to learn more about electricity and to know the reason why Swan's bulb wasn't working properly. When Edison found out what the problem was he wanted to fix it so he can be known for something extraordinary. Edison first presented the light bulb at a store with a little stand with the product next to them so they can show to the customers what it looks like. Many un-wealthy people were able to buy a few light bulbs so they can see at night in their homes. Nine out of ten people ended up with a light bulb for homes. Many stores and buildings bought millions of light bulbs for their work. Many companies couldn't afford the light bulb because they bought so many lights they were losing money every time. Edison and Swan made a huge impact on the world because almost 73% of the whole world uses light bulbs every day. If Swan didn't help Edison with the light bulb then the whole world would probably have a different type of light bulb or maybe nothing at all. Swan knew some more different things than Edison did. He knew different methods of math and science that Edison never knew or heard about. A light bulb is powered by electricity. The power of the electricity in a light bulb is measured in watts. A watt is an international system unit of power equal to one joule per second. There are about one to two hundred watts in one light bulb. There is a chance if you are setting up a light bulb, you might get shocked by the electricity. When you flick the light switch on, the bulb is starting to heat up. If you touch the bulb when it is hot and still warming up, you can get burned. This invention works by when you turn the light switch on, a wire is being attached to the light bulb to it can light up. The invention was used for everyone all over the world. It would make you feel safer at home because a light bulb has less chances of setting a fire than a candle. Now people don't have to rely on the sky for work, they can have normal hours. Some people want oil lamps but now they use them on the road like highways so you can see better at night when you are driving. The inventor(s) were sometimes fighting with each other how the original light bulb was not working properly. Swan though that The first one was the best work he had ever done. He thought that Edison's bulb was worse. They stopped fighting when they heard that the new light bulb was a big seller and they were going to make millions of dollars. Then Swan never thought he was going to be rich someday. He thought that his invention of the original bulb was the best ever. The world has been changed a lot by Mr. Thomas Edison. Edison help our world in many ways and better ways to stay safer. A Light bulb burns for over 40 hours, a candle burns for about 9 hours. The light bulb turns on and off quickly by the switch. You can illuminate a room with dangerous candles. You don't have to change the light bulb as often as a candle once it burns out. You can Move and travel safely in the dark. Thanks to Thomas Edison and Joseph Swan for making these little things come true. All of these little things help you every day life. There are also positives and negatives about the light bulb. Some Positives about the light bulb are, That when you are driving at night, you can see good if you have headlights on your car. Some negatives are, if you touch a light bulb when is hot directly from you skin, it will burn your skin. If you look right into the bulb while it is on it just like staring into a synthetic sun, Very bad for your eyesight. Some negatives Edison couldn't fix or it wouldn't be any good.
Does a light bulb's life depend on its wattage?

Is watts the measurement of a life cycle of a light bulb?
No, the wattage measures only the power the bulb consumes. There are many factors that affect the life of a lightbulb, from its construction to manufacturing process to environmental, etc.
Can you substitute a regular light bulb for a krypton light bulb?
Generally, yes. It will all depend on the voltage and the current capabilities of the supply. Mostly in torches (flashlights), you can. Using a krypton bulb wil be brighter but draw more current, reducing the life of the batteries.

How long does a mood light last?
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.
