I want to know the answer to the following question:
What is the upper limit for LER of an incandescent lamp?
All the background I'm provided with is that "The spectrum emitted by a blackbody radiator at temperatures of incandescent bulbs does not match the sensitivity characteristics of the human eye; the light emitted does not appear white, and most is not in the range of wavelengths at which the eye is most sensitive.". Is that enough to answer the question?
Answer: no
