It depends on the type of bulb used. The term "60 watt" is the power consumed by an incandescent bulb producing about 800 lumens of light. This would use about 1.44 Kw-hr of electricity if operated continuously for 24 hours.
A compact fluorescent lamp (CFL) would require only 13 to 15 watts, about 25% as much electricity.
A light-emitting diode lamp (LED) would require only 6 to 8 watts, about 13% as much as the 60-watt.
What else can I help you with?
If 100 J goes into a light bulb how much energy comes out of the light bulb in total?
The amount of energy that comes out of a light bulb is typically less than the energy that goes in, due to energy losses in the form of heat and light. The efficiency of a light bulb is determined by its design and technology. The amount of useful energy output can vary depending on the type of light bulb used.
Different color light bulb affect how much energy it has?
No, Colored light bulbs holds the same amount of energy a regular light bulb holds.
How much of the electrical energy used to light an incandescent bulb is converted into light energy?
Only about 10% of the electrical energy used to light an incandescent bulb is converted into light energy. The rest is mostly given off as heat.
What is wattage of a light bulb?
The wattage of a light bulb indicates how much power it consumes. It is a measure of the bulb's energy usage, with higher wattage bulbs typically producing more light.
What does the number on the top of a light bulb indicate?
The number on the top of a light bulb indicates the wattage of the bulb, which is a measure of the amount of power the bulb consumes. This can give you an idea of how bright the light will be and how much energy it will use.
How much energy do you save per hour if you replace a 60 W light bulb with a 55 W light bulb?
18,000 J
How much energy does a 5 watt light bulb use off?
A lot
Why is an incadescent bulb a very inefficient light source?
An incandescent light bulb is very inefficient light source because of the amount of heat energy wasted when it is energized.
Why does energy saver give more light than electric bulb of same watt?
Both bulbs output the same amount of energy. The difference is in how much of that energy is output as heat vs the energy output as light. In a standard incandescent light bulb about 10% of the energy is output as light while the other 90% is output as heat. This makes the bulb only 10% efficient. For a florescent bulb the output of light is about 50% and the other 50% is output in heat. This means that a fluorescent bulb outputs five times as much light for the same wattage as a standard incandescent bulb, hence you can get the equivalent of 100 watts of light output for only 20 watts of electricity.
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.
How much energy does a normal light-bulb make in comparison to a colored one?
Both normal and colored light bulbs typically have the same energy consumption in terms of electricity when producing light. The difference lies in the design of the colored bulb that filters out certain light wavelengths to produce colored light, which can make it appear dimmer compared to a normal bulb of the same wattage.
Does the size of the light bulb affect how much energy it uses with wire and a battery?
The size of the light bulb (wattage) affects the amount of energy it consumes. A higher wattage bulb will use more energy than a lower wattage bulb with the same wire and battery. The wire and battery provide the electricity needed for the bulb to produce light.
