Electromagnetic energy.
To plug it in, you use your muscle energy. When current flows through the bulb,electrical energy converted to the heat and light energy in the bulb.
The battery produces electrical energy. If the light bulb is connected between the terminals of the battery, then the bulb will change the electrical energy into heat, and if you're lucky and you have the correct voltage, also maybe some light.
Electrical energy is transferred into light energy, however if the light bulb is an older one, some energy will also be transferred into heat loss.
Mostly electrical to heat and light.
An electric light bulb converts electrical energy into thermal energy which is in the form of radiated light and heat. For example, the " easy bake oven" uses a light bulb to cook the food.
Radiation.
Battery (chemical energy) goes to the wires (electrical energy) which goes to the light bulb (thermal and electromagnetic energy. In the bulb of a traditional flashlight, electric current energy is transformed to heat and then partially to light, when the temperature of the filament in the bulb is sufficient. In an LED type flashlight, little heat is produced and more of the electrical current energy is transformed into light.
Electrical energy is transformed into heat and light. More specifically, electrical energy from the household wiring is turned into thermal energy (heat) by the filament which in turn becomes luminous energy (light). Some energy is lost due to resistance in the conductors.

An erg is a unit of energy equal to 10-7 joules.
Electrical energy (the electric current) is transformed into thermal energy (by heating the filament to incandescence), and this thermal energy creates electromagnetic energy in the form of light.
The general answer is that energy conversion is the conversion of one type of energy into another. We use this principle all the time every day. For instance, we use chemical energy in a battery to create electrical energy to power an electric starter motor. This motor uses the electrical energy to create mechanical energy to start a vehicle. The vehicle converts chemical energy into mechanical energy to make the vehicle go. If you think about the types of energy, you can come up with all sorts of things that change one type of energy to another type. A microphone converts the mechanical energy of sound into electrical energy. There is a boatload of other examples.
