The actual amount of energy that is found when electrical energy is converted to light and heat energy depends on the efficiency of the conversion process and the specific characteristics of the devices involved. In general, when electrical energy is converted to light and heat energy, some of the energy is lost as heat due to resistance in the components and inefficiencies in the conversion process. The actual amount of energy that is converted to light and heat energy can vary, but it is typically less than the total amount of electrical energy input into the system.
