What kind of light bulb gives off the most heat?
Incandescent bulbs produce the most heat for a given amount of light; fluorescent lights produce much less heat, and LED produces the least.
Do CF light bulbs produce as much heat as incandescent bulbs?
No, compact fluorescent bulbs run much cooler that an incandescent bulb. A CF bulb can be unscrewed when the lamp is on whereas an incandescent will give you a bad burn if this is tried.
What watt fluorescent bulb can you use to replace a 60watt incandescent bulb?
fluorescents are about 5x as efficientso a 12W will give about as much light
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.
Was the light bulb invented in accident or in purpose?
The incandescent light bulb as we know it was invented by Thomas Edison. It was invented deliberately and after much trial and error by a very large number of people.
How much of the electrical energy used to light an incandescent bulb is converted into light energy?
About 2 %.
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 much time would a 60w light bulb to run out of light?
The average lifetime of an incandescent bulb is around 2000 hours.

What watt fluorescent bulb can you use to replace a 60watt incandescent bulb?
fluorescents are about 5x as efficientso a 12W will give about as much light
How many 75 watt fluorescent bulbs are needed to give as much light as a 75 watt incandescent bulb?
A 15-watt fluorescent should produce about as much light as a 75-watt incandescent.
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 does a person affect the temperature for an average size room?
About the same as a 100 watt incandescent light bulb.
