reduce electric bills without turning off too many lights
Yes, on an attritional basis, as the old ones burn out-
To convert electric energy into light energy
Yes, electrical energy can be changed into thermal (heat) energy. Light is electromagnetic energy, and electricity can be changed into light energy. We know that a resistance heater changes electrical energy into thermal energy. An electric range does this, as does an electric space heater. We see electrical energy changed into light in fluorescent lights.

An electric bulb, like an incandescent or LED bulb, can turn electric energy into heat and light energy. An electric motor can transform electric energy into motion energy.
When an electric light shines, electrical energy is converted into light energy and heat energy. The electrical energy is converted into light energy, which is the main purpose of the light bulb, while some of the energy is also released as heat energy due to the resistance in the light bulb filament.
A light bulb.
A bulb in a lamp converts electric energy into light and heat energy.
No. An energy saving light bulb is just a light bulb, and can't charge anything. The reason it's called an "energy saving" device is that it can give you the same amount of light while using less electrical energy than older bulbs used.
Radiant (light) energy.
Light is electric/electromagnetic energy!
