I really don't understand what your point really has to do with the original discussion.
Ok, light can be described by its intensity and wavelength. So what? Can you tie this to the original parent post?
You can break it down further - intensity is just the "number" of packets (photons). So, really, light is just frequency and travels at max speed (C) because photons are massless.
Where are we going with this discussion?
Edit: I am not able to respond to you below so I am responding here. You're right on this one - it doesn't matter what the originating source is, light is light whether it is reflected or emitted.
The argument is that since the light is the same, it can't have different effects. Reflected light cannot be inherently healthier than light from an LCD.
