Does a light that is more to the blue end of the spectrum give a false impression of being brighter?
I'm asking because I have one of those wind up LED lanterns that have a quite blue light that glares a lot but in contradiction doesn't seem to illuminate well.

I know that the human eye works best in the green part of the spectrum and is more efficient at detecting colour differences in that range.
Some evidence for saying we evolved in jungles rather than on the savanah?
