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).
What else can I help you with?
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.
How efficient is a 100 watt light bulb?
A 100-watt incandescent light bulb is not very efficient, as it converts only about 10% of the electricity it uses into light, with the rest being lost as heat. It is more energy-efficient to use LED or CFL bulbs, which can produce the same amount of light as a 100-watt incandescent bulb while using significantly less energy.
What invention is similar to the light bulb?
The LED (light-emitting diode) is similar to the light bulb as it also produces light, but it is more energy-efficient and longer-lasting.
What is the curly light bulb called?
The curly light bulb is called a compact fluorescent lamp (CFL). It is designed to be more energy-efficient than traditional incandescent light bulbs.
Who perfected the light bulb?
Thomas Edison is credited with perfecting the first commercially practical incandescent light bulb in 1879. He filed for a patent for his invention and his improvements made the light bulb more efficient and long-lasting.
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
What is the least efficient kind of light bulb?
It is the Incandescent light bulb. Most of the energy are lost as 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?
edunno soz
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.
What is the descriptive use of an LED?
small, cost efficient light bulb.
Has anyone else ever perform efficient light bulb?
hey
How is a led bulb different to a light bulb?
LED light bulbs are more energy efficient, environment friendly, and provide you more savings.
