I want to know the answer to the following question:
What appliance requires more energy due to the use of incandescent lighting?
All the background I'm provided with is that "A comparison of incandescent lamp operating cost with other light sources must include illumination requirements, cost of the lamp and labor cost to replace lamps (taking into account effective lamp lifetime), cost of electricity used, effect of lamp operation on heating and air conditioning systems.". Is that enough to answer the question?
Answer: no
