How efficient is a light bulb?
An incandescent bulb is 96% efficient as a heater, and 4% efficient as a source of light. A fluorescent bulb is only 60% efficient as a heater, and 40% efficient as a source of light. An LED bulb is only 10-20% efficient as a heater, and 80-90% efficient as a source of light (but that light is usually unidirectionally directed... harder to do diffuse lighting with them).
Would a 100 watt light bulb be an incandescent light?
Yes, a 100 watt light bulb is typically an incandescent light bulb that produces light by heating a filament wire until it glows. However, there are energy-efficient LED and CFL bulbs available that can produce the same amount of light using less energy.
What did people use after a the light bulb was invented?
After the invention of the light bulb, people transitioned from using candles, oil lamps, and gas lamps as their primary sources of indoor lighting. The light bulb offered a more convenient and efficient alternative, leading to widespread adoption in homes and businesses.
What is the least efficient kind of light bulb?
It is the Incandescent light bulb. Most of the energy are lost as 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
Which type of light bulb is more efficient light bulb incandesent or an fluorescent light bulb?
Fluorescent is more efficient. Incandescent bulbs should not be used any more, except for some special purposes (mainly where they keep something warm).
How many watts in an energy efficient light bulb?
100
Who invented the energy efficient light bulb?
Bob the builder!
What light bulb is most energy efficient and why?

When comparing two light bulbs the more efficient bulb will produce less what?
The more efficient bulb will produce less heat than the less efficient bulb. This is because a higher proportion of the energy input is converted into light output rather than wasted as heat.
Why is it better to use energy efficient light bulbs?
Energy efficient light bulb saves half of energy consumed by a regular bulb, although it has a lower range light compare to the high energy consumer bulbs.
How efficient is a fluorescent bulb that emits the same amount of light as a 100w incandescent bulb?
It is about 5 times more efficient than the incandescent bulb, in other words for the same light a fluorescent uses one fifth the electric power.
