I want to know the answer to the following question:
How can luminescent light sources be modified to resemble the appearance of 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?
Answer: no
