Yes. The heat and light energy in a torch are separate. From the total energy input to the torch (chemical energy from batteries), Some is useful (the light energy) and some is wasted. (heat/thermal energy) The more efficient an appliance is ,the less energy out of the input energy is wasted. For example, an appliance may be 70% efficient. If it is supplied with 100J (joules) of energy, 70J will be useful and 30J will be wasted. Along with light energy, heat energy is also produced by a torch and is wasted. Heat energy is the most common form of wasted energy in appliances. Other appliances will waste energy in the form of heat, though it may not always be obvious.

Which type of energy other than light energy is produced by incandensent light?
Heat
Which type of energy other than light energy is produced by incandescent lights?
heat energy
What forms of energy is produced when a tv turns on?
heat, sound, and light
When we switch on the light electrical energy is converted into light energy. But when we switch off the light the produced light disappears. In which energy the produced light energy is converted to?
The produced disappears whether you switch it off or not - otherwise it would get brighter and brighter. In a closed room, the light would eventually be absorbed, and converted to heat. Outdoors, the light may go into outer space, going on and on and on... at a very high speed known as the "speed of light". In general, bet on heat. Light turns into heat.
What form of energy is heat produced by filament?
Heat energy. When it is radiated off from the filament, it is mainly infrared light.
What form of energy is stored in a torch?
light and heat
