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?
