I want to know the answer to the following question:
Do fluorescent lights have a higher or lower luminous efficiency than incandescents?
All the background I'm provided with is that "There are many non-incandescent light sources, such as the fluorescent lamp, high-intensity discharge lamps and LED lamps, which have higher luminous efficiency, and some have been designed to be retrofitted in fixtures for incandescent lights.". Is that enough to answer the question?
