Just to share what I have read on Shoudian.org. Hanan_Tomas of Shoudian.org replaced someone’s EYE40 with 7c,5c,3c and 1c LED.
According to him, the light is very sun light alike and comfortable to eyes. He suspect this configuration somehow complete light spectrum better than single tint.
Anyone tried this before here? Maybe can combine more tints better with 7-LED flashlight.
I know that some custom builders of multi-LED setups would add in a single red LED to “increase color rendition”. I have never seen this in action but it must do something special.
