Which bulb lasts longer an incandescent light bulb or a compact fluorescent light bulb?

A regular incandescent bulb uses a lot more energy than a compact fluorescent to produce the same amount of light. Most energy used by an incandescent bulb is wasted as heat which does not give off visible light. Incandescent bulbs are cheaper to buy, but they have shorter lifetimes than other alternatives.

∙ 13y agoIn lighting, the lifespan of a light bulb is often referred to as a life hour rating. Generally speaking, CFLs last longer than incandescent bulbs. Incandescent bulbs last from 1,000 - 2,000hrs whereas CFLs last 3,000-15,000hrs or more.

Why do you use compact fluorescent lamps instead of incandescent bulbs?
A compact fluorescent lamp or CFL has the advantage of consuming less power.It works in the same way as a fluorescent tube light however it is made in a much more compact shape. This means CFLs can be used to replace ordinary light bulbs which have incandescent filaments.If you replace your ordinary light bulbs with CFLs they will use only 20% (one fifth) of the energy to give you the same amount of light output.More informationEnergy-saving lamps, such as normal and compact fluorescents, save a lot of money compared to normal lamps which have an incandescent filament because of the fact that fluorescents don't use a high-temperature filament that produces more heat energy than light energy.Mainly because they run "cool", a fluorescent lamp uses only about one fifth - 1/5 - of the electrical energy used by a lamp that has a hot, incandescent filament.Put another way, you can use five fluorescent lamps, each giving out the same amount of light as one incandescent, for only the same total electricity running costs.Another good thing about fluorescent lamps is that they have a useful life that is between 5 and 10 times longer than an incandescent lamp, saving even more money over a period of years.
What lasts longer a solar or lunar eclipse?
The lunar eclipse lasts longer than a solar one
What lasts longer a dimmed light or a fully powered light?
The mechanism that fails in an incandescent lights is the filament. It degrades over time because of current flow. Hence, you would expect the dimmed light (less current) to last longer. This would not necessarily be true for other types of lights.
If you operate an incandescent light bulb at less than its rated voltage?
Since an incandescent light bulb is an appliance that has a fixed electrical resistance, operating it at less than its rated voltage means that it will draw less than its rated current and will produce less light.
Does a regular light bulb use more energy than a fluorescent light bulb?
uses less electricity and produces less heat
Why have compact fluorescent light bulbs come on the market?
An ENERGY STAR qualified compact fluorescent light bulb (CFL) will save about $30 over its lifetime and pay for itself in about 6 months. It uses 75 percent less energy and lasts about 10 times longer than an incandescent bulb.
How does light from cfl bulb compare?
When you compare a CFL (Compact Fluorescent Lamp) bulb to an LED bulb, the CFL bulb has a shorter lifespan. The CFL bulb also uses more electricity for the same brightness Also a CFL lasts longer and uses less electricity (for the same brightness) than an incandescent bulb.

What are compact fluorescent light bulbs?
I am not aware of any inceased fire hazards associated with compact fluorescent lamps. As an electrical contractor I have installed hundreds without any safety issues. "Early failure" is usually the main complaint. They do get warm, but not as hot as regular incandescent lamps. No one seems to ask if the incandescent lamps are a fire hazard, but they can be. Any lamp that gets hot can be the source of ignition in certain rare cirumstances, such as if gasoline spills on the floor and the room fills will flammable vapors. Always use lamps and appliances that have a testing laboratory listing such as "UL" or "ETL" or "CSA" to ensure they have been tested for general safety in household use.
What light bulb lasts longer a CFL or a regular one?
Fluorescent bulbs, including Compact Fluorescent Lamps (CFLs) are designed to last longer because they have no filament to burn out.However, many of the current CFLs will prematurely fail (before their estimated lifespan) because the components or designs of their ballasts were compromised when translated from the older tube-type fluorescents. These ballasts are sensitive to heat buildup in enclosed fixtures. The life of any bulb is greatly affected by the number of cycles (on and off) they experience, as well as any fluctuations in the power supply.

What does it cost to buy and use one 25-w compact fluorescent bulb compared with number of incandescent bulbs for 10000 h of light?
The CF bulb costs let's say £3 and lasts 8000 hours during which time it will use up 8000 x 25 watt-hours of energy, that is 200,000 watt-hours or 200 units, costing 200 x £0.15 which is £30. An incandescent bulb would have to be 100 watts for the same light, i t might cost 60p but its life is only 1000 hours so you would need 8 to last 8000 hours, costing £4.80. The power used in 8000 hours would be 8000 x 100 watt-hours, or 800 units, costing 800 x £0.15 or £120. The total cost is: compact fluorescent: £33, incandescent: £124.80.
