Interesting!
I must admit I don't know my lightbulbs...this is groundhubby territory...I don't do oil or lightbulbs...sorry...I should learn about it.
Anyway, I, too, as CArroll has said, don't feel my best in certain flourescent lights, although there must be different kings. We have flourescent bulbs in our kitchen and they don't bother me, but in my office they keep me feeling sleepy...and there are certain stores I go into, only if it's dark outside...and my eyes play tricks on me and I feel weirdly hyper and sleepy at the same time...no headaches, but some of those lights do something strange to me, mainly if it's dark outside...sounds bizarre, but it's true.
We have a lot of those LED lights (don't ask me any particulars...I'm totally ignorant; I just know groundhubby calls them LED) for areas where we don't really need a lot of clear vision...like where we wouldn't read or work on something hard to see, or anything like that. Supposedly they take little energy and last forever. I also have windup flashlights with these LED lights in them that I use to take care of doggies' needs.
Sometimes here at work I find it necessary to turn off my lights and just do computer work in the dark, just so I can stay un-sleepy! Not like the work is exciting enough to keep you charged up...

--it's weird too, cuz I'm not a person who actually sleeps much or can sleep much at all...but certain lights just seem to go directly to my ol' groundhog brain!
I know a lot of people who get onto that freecycle thing!
