I think it's the law in the UK and they save energy and are therefore more eco-friendly but they are also kinda annoying because they are quite dull at first.
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.
If a light bulb wastes about 85% of its energy, then it is approximately 15% efficient. This means that only 15% of the energy it consumes is actually converted into light, while the remaining 85% is lost as heat.
The relationship between the wavelength of light emitted by a light bulb and its energy efficiency is that shorter wavelengths, such as blue light, are more energy efficient than longer wavelengths, such as red light. This is because shorter wavelengths carry more energy per photon, allowing for more efficient conversion of electricity into light.
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.
Yes. Part of the energy is converted to light, part to heat. The percentage depends on the type of light bulb. Fluorescent and LED light bulbs are more efficient than incandescent light bulbs. A 60-watt incandescent bulb will be uncomfortable to remove from the socket with your bare hands after turning it off. However, a 100-watt bulb will burn you if you remove it with your bare hands after turning it off.
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.

there are 100 joules in an energy efficient light bulb 75 joules go towards the light and 25 joules go towards the heat
An example of an energy efficient device includes an energy efficient light bulb.
It is the Incandescent light bulb. Most of the energy are lost as heat
LED light bulbs are the most energy-efficient option for your home.
The job of a light bulb is to convert electrical energy into visible light energy. (Not ALL of the electrical energy a bulb uses is converted to light energy. Their efficiency is quite low. An incandescent light bulb is more efficient as a heater than as a source of visible light. Fortunately, our eyes are very sensitive.)
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.
The energy-efficient light bulb was not invented by a single person. However, Thomas Edison's incandescent light bulb laid the foundation for modern developments in energy-efficient lighting, leading to the creation of technologies such as compact fluorescent lamps (CFLs) and light-emitting diodes (LEDs) that are more energy-efficient.
LED light bulbs are more energy efficient, environment friendly, and provide you more savings.
