Replace it, but take the old one to the correct place for disposal
No, the most energy efficient bulbs are LED (Light Emitting Diode) light bulbs.
A greater percentage of light, and a smaller percentage of infrared radiation and heat.
If you're using it to generate light, 10 percent efficient. If you're using it to generate heat, 90 percent efficient.
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.
When lighting a light bulb, it is changed into light and heat/thermal energy.
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.
An example of an energy efficient device includes an 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
It is the Incandescent light bulb. Most of the energy are lost as heat
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.)
LED light bulbs are more energy efficient, environment friendly, and provide you more savings.
No, the most energy efficient bulbs are LED (Light Emitting Diode) light bulbs.
The energy efficient light bulb costs several times as much as the normal (incandescent) light bulb. The exact prices may vary from region to region. In any case, the extra cost will be more than compensated by savings in electrical energy, over the lifetime of the 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).
