Since LED bulbs come in a variety of sizes there is no one answer. If we consider Watts then LED bulbs from 1 to 12 Watts are common. The higher end of quality LED lights that are commercially produced generally yield about 80 lumens per Watt. This means for a 10 Watt LED bulb your looking at 800 Lumens. This is higher than both CFL and incandescent lights. LED bulbs can save money in the long run due to the lower energy use, but they require a larger up front investment. See below for a link to an example of an LED bulb that produces 460 lumens.

∙ 12y ago1) 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.

Will a regular LED bulb work in a refrigator?
yes
What is the difference between led light and a normal light bulb?
a normal light bulb gives off more light
How many joules are in 1500 grams?
Voltage is electrical pressure and Joules is a power rating so other info is needed
How many joules in a punch?
Depends on how much force is placed into a punch.
When 60 W means that W joules of energy are transferred into the bulb each second. In use how much energy is given out by the bulb each second?
The light bulb will use electrical energy at the rate of 60 W (60 J/s), and it will emit that energy, also at the rate of 60 W.Note that in any real light bulb, only part of the energy is emitted as visible light. The remainder is mainly heat.
How many joules are saved by a energy efficient light bulb?
there are 100 joules in an energy efficient light bulb 75 joules go towards the light and 25 joules go towards the heat
How many joules does a 40 watt ight bulb convert in 10 seconds?
Four Hundred Joules
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 LED equals a watt?
it depends on the kind of led bulb
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).
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...
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.
What is the power of a light bulb that converts Electrical energy at a rate of 100 joules per second?
100 joules/second = 100 watts.
What is the power of light bulb that converts electrical energy at a rate of 100 joules per second?
100 joules/second = 100 watts.
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 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 much power in watts will an led bulb consume if its energy is 6 joules?
Joules (energy) are not equivalent to Watts (power).If something converts 6 Joules every second, it is 6 Watts. If it takes ten seconds to convert 6 Joules, its power is 0.6 Watts.Multiply the Watts by the seconds to find the Joules.CommentYou do not 'consume' power. Power is simply a rate; you cannot consume a rate! You consume energy; the rate at which you consume it is power.
