You actually think you know more about someone than they do about their own perceptions (leaving aside scientific research in this area and practical, real world considerations)...
Wow.....
His comments are right in line with scientific research.
Most people who think that certain types of bulbs give them headaches or that they can see strobing really can't tell the difference in double-blind tests and are no more likely to get headaches or dizziness with one type of bulb than another.
The color and brightness of a bulb have a lot more effect regardless of the type of bulb.
If you have "scientific research in this area" that supports your claim, please present it.
