You better go back to school. There's some things they didn't cover, apparently. Like why a sunset is actually red, not the superstitious nonsense you think.
When you take a bulb that is the same color as the sun appears, go to an otherwise dark room, and put a sheet of white paper in front of it, the paper looks yellow. If you have a bulb with more blue light as a component, the paper looks closer to white, the way it looks in sunlight. Why is that, Mr. "I took three extra classes in college so now I have a Masters degree"? Oh that's right, you wouldn't know because you only took a few extra classes in college, they didn't cover things like "why is the sky blue and not red."
I made a mistake in that blue is a shorter wavelength, not longer. Everything else was accurate. A shorter wavelength has more energy and travels farther, especially through dust and haze.
As far as your claims that "nothing happens in that distance," that's a comment from someone that hasn't bothered to see if reality actually matches their assumptions. Ever see sodium street lights, you know they amberish-yellow ones? They use that particular bulb because that frequency of light provides the most visibility in fog. And because of the particular color of the light, it causes less light pollution than mercury vapor lights, which are definitely more bluish in color. If they asked you, you'd tell them it wouldn't matter what frequency of light they used. Good thing they didn't ask you. Instead, they actually tested different lights to see which worked best under those conditions. God forbid one actually observe the physical world before making pronouncements :/
You got your Masters in Sussex? Good to know. I don't want to make the mistake of going there and getting trained by tossers who don't know blue from red.

He really should email the folks at the VLA so they stop wasting their time and money.
Pwnt.
