The popular energy of flashlight are Rechargeable Li-on battery, Alkaline battery.
The spring in a flashlight completes the circuit by providing a connection between the battery and the light bulb. It does not convert electrical energy into light energy - the light bulb does that function.
Potential energy
Energy in a flashlight changes from stored chemical energy in the battery to electrical energy when the battery powers the light bulb, which then converts electrical energy into light and heat energy.
When a battery-operated flashlight is turned on, the chemical energy stored in the battery is converted into electrical energy, which powers the light bulb, producing light energy and heat energy.

The flashlight can not be turned on as it no power now.
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.
A flashlight battery contains stored chemical potential energy that is converted into electrical energy when the flashlight is turned on. This electrical energy is then used to produce light energy, which is a form of radiant energy.
You cannot turn on a flashlight without battery inside. That's impossible if the only energy of flashlight is a battery.
In a solar panel flashlight, the energy transformation involves converting solar energy into electrical energy. The solar panel captures sunlight and converts it into electricity, which is then stored in a rechargeable battery in the flashlight for later use. When the flashlight is turned on, the electrical energy stored in the battery powers the light source.
