Candles are able to start fires more easily than are light bulbs, although high wattage light bulbs are able to start fires as well. A smaller concern but a concern nonetheless is that burning candles consumes oxygen, and a light bulb does not. Also in a dark room a candle might unexpectedly go out, causing a safety concern in attempting to relight the candle in the dark.

What was the use of Thomas's light bulb?
To provide light in a longer lasting and more effective way than a candle
Why do you think a light bulb feels warm?
A light bulb is designed to take electrical energy and radiate it as electromagnetic energy.It would be nice of all of that energy came out in the form of light, but that has never been accomplished yet. An incandescent light bulb ... the original kind ... radiates much more heatenergy than light energy. In other words, an incandescent light bulb works much more efficientlyas a heater than it does as a source of light.
What light does a very hot light bulb produces more of what type of light than a light that is cool to the touch?
yes
Is 8 people enough to change a light bulb?
Eight people are more than enough to change a light bulb. Usually one person is needed.
Does a 60-watt electric light bulb create heat energy?
Yes. Part of the energy is converted to light, part to heat. The percentage depends on the type of light bulb. Fluorescent and LED light bulbs are more efficient than incandescent light bulbs. A 60-watt incandescent bulb will be uncomfortable to remove from the socket with your bare hands after turning it off. However, a 100-watt bulb will burn you if you remove it with your bare hands after turning it off.
How did the Light bulbs change cultures?
The light bulb provided light after sundown that was safer and more efficient than candle light so that greater productivity could be achieved during evening and night periods.
What was the use of Thomas's light bulb?

How did the light bulb change technology during Thomas Edison's time?
They supplied a reliable source of light compared to fire and candles. They didn't burn out as quickly as fire and candles. One big thing, though maybe not exactly a technology changer, was that it was a lot safer than a fire or candle.
Does a candle create more pollution than a light bulb?
No. Burning 3 candles puts out slightly more CO2 than a 13 watt CFL bulb. However, The CFL bulb puts out about 24 times more light than 3 candles. In terms of a 100 watt incandescant lightbulb, it produces roughly the amount of light produced by 120 candles, however only produces about as much CO2 as 23 candles, so you could say it's about 5 times more efficient (in terms of pollution output) than a candle. A CFL bulb, then, is about 20 times more efficient than the candle.
What led Edison to invent a light bulb?
Electricity was less expensive, and safer than gas for lighting purposes. He saw Joseph Swan do it.
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.
How did the invention of the light bulb change your lives?
Lightbulbs were easy to turn on and keep on.Thomas Alva Edisson invented the Electric bulb Among all of his other inventions, the invention of electric bulb was the most revolutionary without which the entire work force on earth would have been dependent on daylight or oil lamps etc
Which of the areas of technology best classifies the light bulb?
The incandescant light is more of a heat bulb than a light bulb, being 200% less efficient (on average) in producing the same amount of light (measured in lumens) than a fluorescent bulb. That being said, the light bulb would be considered part of a luminaire.
How many amps in a 40 watt light bulb?
A lumen is the perceived intensity of the light, as seen by the human eye. The lumen value is largely determined by the the nature of the light, i.e. the sum of the different wavelengths of the light being transmitted by the particular bulb type.The standard tungsten wire-filament ('incandescent') bulb radiates a different type of light to a flourescentlight.* a 230 V, 40 watt incandescent bulb produces a light (quality) of about 400-500 lumens,* a standard 230 V flourescent lamp of only 7 watts will produce exactly the same value of lumens, i.e. 400-500 lumens. * the cool white XLamp XP-G 3.5 V LED lamp of only 3 watts will produce a similar value of lumens, i.e. 350 lumens. And is safer for the workers that make them and better for the environment. It is currently more expensive, but prices have been dropping about 20% per year. Therefore LED light bulbs convert electricity into light more efficiently than incandescent or florescent light bulbs. * For more information, See Related links below this box
What is a word that means a light bulb that uses more energy than a fluorescent light bulb?
incandescent
What is more important the light bulb or fire?
This question is an opinion rather than one correct answer. An incandescent light bulb is lighted by electricity and by heating the filament wire to a high temperature until it glows. A fire would be more important because without it, the light-bulb would never been invented in the first place, since the candle wouldn't be existing. Historically, fire is one the the fundamentals of civilization.
What are some brands that offer candle warmers, which are supposed to be safer than burning candles?
Candlewarmers.com is a popular brand that sells those.
