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).
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.
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.
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.
The curly light bulb is called a compact fluorescent lamp (CFL). It is designed to be more energy-efficient than traditional incandescent light bulbs.
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.
there are 100 joules in an energy efficient light bulb 75 joules go towards the light and 25 joules go towards the heat
It is the Incandescent light bulb. Most of the energy are lost as heat
Fluorescent is more efficient. Incandescent bulbs should not be used any more, except for some special purposes (mainly where they keep something warm).

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.
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.
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.
small, cost efficient light bulb.
hey
LED light bulbs are more energy efficient, environment friendly, and provide you more savings.
