Read the label on the container. The light bulb will be rated "B-10" life. This refers to a statistical number value. "B-10" Life is the average life span a bulb will last for 90% of those tested. If you went purely by the "average" time to burn out, then that is not specific. One brand of light bulbs can have a higher Average. But if it has a lot of scatter in the data, then that would mean some bulbs could fail much earlier and some much later. On the other hand, if you determine a bulb has a X hour "average" life with a minium scatter factor, then more of the bulbs will perform closer to the average. Read the label on the box.

∙ 13y agoPotentially longer than your lifetime if it is an incandescent light bulb as is the case with the Centennial Light in the Firehouse at 4550 East Avenue, Livermore, California!
Cheap incandescents usually have a rated life of at 1,000 hours. Better quality bulbs around 2,000 hours. Longlife bulbs at around 6,000-8,000 hours, with some speciality bulbs rated at over 25,000 hours.
Compact fluorescent light bulbs are rated between 4,000 and 12,000 hours of actual use when switched on.
These ratings are under ideal conditions and can be greatly reduced if their miniature ballast circuits overheat,such as when the bulbs are used in fully enclosed and/or recessed lighting fixtures.

∙ 15y agoRephrasing the question, what shortens the life of a 100W bulb. It is the cycling of the filament from on to off. The filament temperature goes from white hot to cold every time the bulb is turned on. This expansion and contraction of the filament is what shortens the life of the bulb. Most bulbs have three filament supports, longer life bulbs have five supports but usually cost a bit more money. Excessive vibration is another cause that shortens the life of a light bulb.

∙ 14y agoA 100 Watt light bulb from Nella Park should give you about 2000 hours -- if they still make them. A 100 Watt light bulb from overseas, I rather not say.

The answer is:
- 100W = 0.1kW
- time = 1h
Result: 0.1kWh if it's on for 1h

The problems of electricity two light bulbs of 100 watt and one 60 watt both operation in a 220V circuit. Which bulb has the higher resistance and which bulb carries the greater current?
A 100 watt 220 volt light bulb (or anything consuming 100 watts on 220 volts) draws 100/220, or .45 Amps. It will also have about 220²/100, or 484 ohms resistance. A 60 watt 220 volt light bulb (or anything consuming 60 watts on 220 volts) draws 60/220, or .27 Amps. It will also have about 220²/60, or 807 ohms resistance.
There is a 100 watt light left on for 30 days and uses 72 kilowatt-hours suppose thecost of this electricity is 5.76 how much electricity does a 100 watt light bulb use in one week what's the cost?
Check with your electric company. If you switch to 100 W fluorescent bulbs they are only about 14 watts usage. Those are the new energy efficient bulbs. You still get 100 W, but less wattage used. Therefore you bill should be reduced by some. You won't see it right away, it's over the long haul. I have switched most of my lighting (except one lamp and my kitchen) to those bulbs. They last a long long time. I will be switching my kitchen to a new fixture so I will use the 100W energy efficient bulb and get just as much light as 100 incandescent bulb. I'll put 4 in and get 400 W for 56 watts charged. < > < > 5.76/30 days = .192 cents per 24 hour period. .192 x 7 days = 1.344 dollars a week
Are halogen bulbs more energy efficient than traditional incandescent bulbs?
Well, if they're both 40 watt bulbs they use the same amount of electricity. But incandescent bulbs produce a lot of heat as well as light. Fluorescent bulbs don't produce (much) heat, so they can use their power to produce light. So you can use fluorescent bulbs of lower wattage to produce the same amount of light.So for the same amount of light, fluorescent bulbs use less electricity than incandescent bulbs.
How many kilowatt do 100 watt bulbs use?
That depends both on the light bulb's power rating, and how long you want to light it! Use the formula: energy = power x time If the power is in watts and the time in seconds, then the energy will be in joules (= watt-seconds). Alternately, if the power is given in watts, you can divide by 1000 to convert to kilowatts. Then, if you multiply by hours, you get kilowatt-hours. Note that the unit used by utility companies tp charge you is kilowatt-hours.
Will 1 amp deliver 100 amps in 100 hours?
No. One amp is one amp. It does not matter how long you supply that current. You could say that one amp for 100 hours is 360,000 coulombs, but that is not a useful piece of information.Now, if you want to talk about energy, that is a different story, but you need to talk about watts, not amps.One amp is one coulomb per second.One volt is one joule per coulomb.One watt is one joule per second, which is why watts is amps times volts.One watt for 100 hours is 100 watt-hours, or 360,000 joules. Joules is energy. That is useful information.
What is the rhyming word for a 100-watt bulb?
The rhyming word for a 100-watt bulb is "dull."
How do you use the word dimmer in a sentence?
A 40 watt bulb is dimmer than a 100 watt bulb.
What percentage is a 100 watt light bulb brighter than a 60 watt light bulb?
Original answer: Because it gives off more power. Updated answer: In general, because the 100-watt bulb produces more total light (lumens) because it also consumes more power than the 60-watt bulb. However, a 60-watt can produce more lumens than a 100-watt bulb, depending on the types of bulbs in question.
How many lumens are in a 1000 watt incondescent light bulb?
A 1,000 watt is 15,000 lumens. A 100 watt bulb is 1,500 lumens.
What are the carbon emissions from a 100 Watt light bulb?
100
What is the highest watt light bulb that there is?
the highest light bulb is 100
Can you use a 50 watt halogen bulb for a 100 watt halogen bulb?
Yes. It just won't be as bright.
Where do you find a watt?
A watt is a measurement of electricity, usually pertaining to light. Light bulbs luminosity is graded by wattage, such as a 60 watt bulb, 100 watt bulb and so on. You would find a watt in a light bulb, to start.
Why is 60 watts written on the bulb?
It is probably a 60 watt bulb (believe it or not). Bulbs are rated in watts. A 100 watt bulb is brighter and consumes more power than a 60 watt bulb
How much more money will it cost if you use 100 watt bulb then a 60 watt bulb?
Almost twice as much as 100 is almost twice 60.
Does a 100 watt bulb produce more heat than a 25 watt light bulb?
yes, 4x more
What rhymes with 100-watt bulb?
