You can make a light bulb more efficient by using LED bulbs that consume less energy and have a longer lifespan compared to traditional incandescent bulbs. Additionally, consider using dimmer switches or timers to control the amount of light output based on your needs, which can also help save energy.
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.
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).
Yes, we could still live without the light bulb as there are alternative sources of light such as candles, oil lamps, and natural daylight. The light bulb has made life more convenient and efficient, but it is not a necessity for survival.
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.
Fluorescent is more efficient. Incandescent bulbs should not be used any more, except for some special purposes (mainly where they keep something warm).
LED light bulbs are more energy efficient, environment friendly, and provide you more savings.

It would be more different since it will take up more power than the less efficient light bulb. Instead of using all the solar power it will probably need the forces of 2 energies to light the 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.

Efficiency is typically associated with minimizing losses in a circuit. If you have no load you couldn't compute efficiency. If there is a load you need to determine what you are trying to measure. For example, in an incandescent light bulb a lot of power is wasted in heat. So if light is what you are looking for an incandescent bulb isn't very efficient. A compact fluorescent would be more efficient. However, if you were using a light bulb to power an "Easy Bake" oven it would be more efficient.
A fluorescent light bulb contains a gas which produces UV light when it comes in contact with electricity. Contrary to a normal light bulb this does not create any heat and is far more energy efficient.
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.
