1) The power use of bulbs is specified in units of power, not energy. In other words, watts - which means joules per second.

2) Light-bulbs come in different capacities.

3) It is incorrect to say that the energy (or power) "is in" the light-bulb. The light-bulb simply transforms one type of energy to another, using electrical energy which is NOT stored in the light-bulb.

Does a 150 watt bulb do 150 joules of work?

Every second a 150 Watt bulb converts 150 Joules from electricity into heat and light. The number of Watts tells you how many Joules pass per second.

How many joules does A 100 watt light bulb consume in 24 hours?

100 watts means 100 Joules/Second. So in 24 hours, the bulb would use 24*60*60*100 Joules. so that's 8,640,000 joules

How many joules does 60W bulb consumes in 1 hour?

6o Wh = 216000 J

How many btu's of heat produced by incandescent light bulb?

Almost 90 % of electrical energy provided to an incandescent light bulb goes as heat and rest as light. A 100 Watt bulb puts out 100 Joules of heat per second. So - for one minute it would put out 6000 Joules (100 Watts X 60 seconds). 1 BTU (British Thermal Unit) of heat = 1055.056 Joules. So a 100 watt bulb, burning for one minute would put out 5.68 BTUs of heat. ( 6000 Joules / 1055.056 Joules) = 5.68 BTUs. Same bulb burning for one hour would generate 341 BTUs of heat.

How many lumens does 1 led light bulb produce?


How many lumen's are in a 20 watt led bulb?

1600 Lumens

What is the energy used in one second when a bulb have 40Watts.?

40 Joules, I think, as the formula for Watts is Joules/Second = Joules per second 40 Watts should equal 40 Joules per one second...

How many hours does an LED light bulb last?

led bulb lasts for more than 24 hours if they glow continuously but if we use the periodically(from some time to time ) they lasts long for many years

How many lumens does a 3W LED warm white GU10 bulb produce?

How many Joules of electrical energy does a 100 Watt light bulb consume from the electrical supply in 2 seconds?

Watt means joules/second. It refers to the amount of energy a device uses, in this case. Multiply the power (in watts) by the time (in seconds) to get the energy (in joules).

How many joules are in 56 kilo joules?

56 kilo joules = 56,000 joules

If the light bulb from number 10 radiates 100 watts times 100 joules per second of photons. How many photons per second are radiated?

Given the wavelength of the photons from above, 3000 nm you just calculate how many joules each photon has and divide that into 100 joules per second.

The power of a light bulb that converts electrical energy at a rate of 100 joules per second is what?

100 joules/second = 100 watts.

How many joules of power does a 60 w light bulb use when lit?

1 watt= 1 joules/1 sec60 w = 60joules/minuteor=3600joules/hour

How many joules does a 100 watt light bulb use in 1 minute?

100 watts running for 60 seconds uses 100 x 60 Joules of energy. A Joule is the same as a watt-second.

How many joules of energy does a 100Watt light bulb use per hour?

It's 100 watts times 3600 seconds, that's 360,000 joules of energy. A joule is 1 watt for 1 second.

How many joules of energy does a 100 watt light bulb have?

Can I get an LED light installed into my incandescent downlight cans?

Yes, absolutely. As long as the LED bulb and incandescent bulb have the same base they will both fit the socket. The LED bulb will also run much cooler than the original incandescent bulb.

How many watts does it take for an Led bulb vs a 60 watt incandescent light bulb?

LED bulbs com in different powers, so there's no way to tell. At a guess a 10W LED might compare to a 60W incandescent.

Which has a longer life an LED or an incandescent light bulb?

An LED has a longer life than an incandescent light bulb.
