The flashlight uses three different forms of energy. It's first starts as chemical energy, then to electrical, and finally to electromagnetic (visible light.)
The light produced by a flashlight is electromagnetic radiation.
"Go through"? The process of charging and using a crank flashlight includes the existence of thermal, mechanical, electromagnetic, sound and radiation energy.
Heat to make the filament glow white hot and emit light (electromagnetic 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.

A flashlight can transform electric energy to light energy and heat energy.
Battery electric energy is converted to light energy of flashlight.
The flashlight does.
That energy is called "electromagnetic waves" or "electromagnetic energy".
flashlight: the battery in the flashlight transforms it's chemical stored Energy into electrical Energy which is then transformed into radiant energy because of the light the flashlight gives off.
The popular energy of flashlight are Rechargeable Li-on battery, Alkaline battery.
The electric energy will be transfered to light energy and heat energy once flashlight turn on.
