Is no lighting considered too little? I like to sit in the dark with nothing but a computer monitor for light. I have noticed this greatly reduces eye-strain and distractions, but perhaps that is just me.
For most people, sitting in the dark with only their monitor giving off light massively increases eye-strain.
I've used this for years and it makes working during the evening so much better.
As an example I used to be a midnight owl but now with kids I have to make the most of my daytime hours and squeeze as much sleep as I can in the night hours. I totally get the warmth of working the night hours but I am also fine with being in the zone during the daytime. You can shape your brain to get used to anything.
