A flashlight is given off light and heat energy once turn on.
A flashlight gives off both light energy in the form of visible light and heat energy, typically in the form of infrared radiation. The light energy allows us to see in the dark, while the heat energy is a result of the energy lost in the conversion process from electrical energy to light energy.
Waste energy in a flashlight is mainly given off as heat, due to inefficiencies in converting electrical energy to light energy. This heat is produced by the resistive losses in the electrical components and by the inefficiency of the light-producing materials. Additionally, some energy may also be lost as sound vibrations or through the battery's chemical processes.
There is more energy in the battery than that given off as light and heat for two reasons. 1) Some energy is lost due to resistance in the battery. As current flows, energy is lost to heating of the battery due to this internal resistance. 2) As the battery operates, the voltage falls until it is too low to heat the bulb to incandescence. Yet energy remains in the battery, but this last energy is at too low a voltage to be useful.
The heat given off by an object is called thermal energy. It is a form of energy that is transferred in the form of heat due to a temperature difference between the object and its surroundings.
Most energy is given off as heat, which is a form of energy that is transferred from one object to another due to a difference in temperature. When energy is transferred or converted from one form to another, some amount of energy is usually lost as heat.
All of the energy in the battery, or most of it, is eventually given off as heat and light.

A flashlight gives off light energy, which is a form of electromagnetic radiation. The light energy is created when the flashlight's batteries produce electrical energy that powers the light bulb or LED to emit light.

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 process in which energy is given off is called an exothermic change. The energy released can be in the form of heat, light, electricity, or sound
