I want to know the answer to the following question:
Up to what wavelength does the human eye perceive IR LED sources as red?
All the background I'm provided with is that "However, particularly intense near-IR light (e.g., from IR lasers, IR LED sources, or from bright daylight with the visible light removed by colored gels) can be detected up to approximately 780 nm, and will be perceived as red light.". Is that enough to answer the question?
Answer: yes
